1.02 General Design Gonsiderations
Various Warrang Tables have been included in Paragraph 1.05 citing various requirements by which specific
warranty coverage can be obtained. Appropriate Warranty Table should be referenced to ensure proper warranty
coverage.
A. The maximum roof slope for Mechanically Attached Roofing Systems is 18" in one horizontal foot. There are no
maximum slope restrictions for the application of the Fully Adhered Roofing System.
B. The mechanically attached roofing system is not acceptable for installations on steel decks lighter than 22 gauge
unless the steel deck is used in conjunction with lightweight concrete and a minimum of 360 pounds pullout per
fastener is achieved with HPVX Fasteners into the steel deck below. A Fully Adhered Roofing System may be
specified or refer to the Metal Retrofit Roofing System Specification, published separately for other roofing options.
C. Certain petroleum based products, chemicals, and waste products may not be compatible with these roofing
membranes. Contact Versico for verification of compatibility and recommendations concerning an acceptable roofing
membranes.
D. Metal-Edge Systems and Copings should be designed in compliance with Section 1504.5 of the lnternational Building
Code and shall be tested in accordance with ANSI/SPRI ES-1 .
E. Concentrated loads from rooftop equipment may cause deformation of insulation/underlayment and possible damage
to the membrane if proper protection is not provided. A protection course or sleepers must be specified.
F. lt is the responsibility of the specifier to review local, state and regional codes to determine their impact on the
specified Versico Roofing System.
G. lt is the responsibility of the building owner or his/her designated representative to verifi structural load limitation. ln
addition, a core cut may be taken to verify weight of existing components when the roofing system is to be specified
on an existing facilitY.
H. Construction Generated Moisture / Vapor Drive
1. On new construction projects, especially in cold climate regions, moisture generated due to the construction
process could adversely impact various components within the roofing assembly if not addressed. Refer to
besign Reference DR-01-21 "Construction Generated Moisture" included in the Versico Technical Manual.
2. On structural concrete decks, when a vapor retarder is not used, gaps in the deck along the perimeter and
around penetrations must be sealed along with vertical joints between tillup panels, if present, to prevent
infiltration of hot humid air and possible moisture contamination resulting from condensation. This is specifically
important when adhesive is used to attach the roof insulation.
NOTE: lf left unaddressed, collected moisture could weaken insulation boards and facers resulting in a blow-off or
increase the probability of mold growth.
L Drainage
1. Drainage must be evaluated by the specifier in accordance with all applicable codes. Slopes may be provided
by tapering the structure or through the use of tapered insulation; a sufficient number of roof drains should also
Thermoplastics 1/2023 4
J.
be specified and properly located to allow for positive drainage. Significant ponding that could remain after 48
hours should be eliminated with the addition of auxiliary drains in low areas where ponding is anticipated.
Versico specifically disclaims responsibility for the design and selection of an adequate drainage
system and drain accessories. Selection must be made by the building owner or the owner's design
professional
2. Small incidental areas of ponded water will not impact the performance of this roofing system, however, in
accordance with industry standards, the roofing assembly should be designed to prevent ponding of water
on the roof for prolonged periods (longer than 48 hours). Good roofing practice dictates proper drainage to
prevent possible excessive live load and, in the event of a roof leak, to minimize potential interior damage to the
roofing assembly and to the interior of the building.
3. Ta'pered edge strips, crickets or saddles are recommended where periodic ponding of water may occur.
When the slope of the taper exceeds 2 inches to one horizontal foot, additional membrane securement at the
base of the tapered edge strip will be required.
4. Subject to code requirement, it is recommended that a minimum roof slope of 1/8" per horizontal foot be provided
to serve long-term aesthetics. On new construction projects, roof drains should be positioned in areas where
minimum deflection is anticipated. Slopes greater than 1/8" per foot should be considered due to possible roof
deflection.
Retrofit - Recover Projects (when the existing roofing material is left in place)
1. The removal of existing wet insulation and membrane must be specified. The specifier shall select an
appropriate and compatible material as filler for voids created by removal of old insulation or membrane.
2. Entrapment of water between old and new membrane can damage and deteriorate new insulation/underlayment
between the two membranes. lf a vapor retarder or air barrier is not specified, Versico recommends existing
membrane be perforated to avoid potential moisture accumulation to allow for detection of moisture to enable
the building owner to take corrective action. This can be accomplished by drilling approximately 3/4" diamele_r
holes every 100 square feet in the existing built-up roof or single-ply membrane (excluding non-reinforced PVC
membrane).
3. lf total removal of existing non-reinforced PVC membrane is not specified, existing membrane may be cut into
maximum 10'x 10'sections, when the new insulation or membrane underlayment is to be mechanically attached.
4. Regardless of the type of membrane or assembly selected, any loose flashings at the perimeter, roof drains and
roof penetrations must be removed.
1.03 Quality Assurance
Building codes are above and beyond the intended purpose of this specification. The building owner, owner's
repres6ntative or Specifier should verify local codes for applicable requirements and limitations. lt is the
responsibility of the specifier to review local, state and regional codes to determine their impact on the specified
Versico Roofing System.
NOTE: For code approvals achieved with the Versico Roofing Systems, refer to the Versico Code Approval Guide,
DORA (Direciory of Roof Assemblies), Factory Mutual (FM) Approval Guide or Underwriters Laboratories (UL)
Fire Resistance or Roofing Materials and Systems Directories'
A. When recovering or retrofitting an existing roof system, the addition of new insulation (type and thickness) may alter
the fire performance characteristics of the assembly. Building owners or their designated representatives shall consult
the local code enforcement agency to avoid potential code violation.
B. Versico recommends the use of Versico supplied products for use with VersiWeldA,/ersiFlex Roofing Systems. The
performance or integrity of products by others, when selected by the specifier and accepted as compatible by
Versico, is not the responsibility of Versico and is expressly disclaimed by the Versico warranty.
C. This roofing system must be installed by a Versico Authorized Roofing Contractor in compliance with drawings and
specifications as approved by Versico.
D. There must be no deviations made from Versico's specifications or Versico's approved shop drawings without the
PRIOR WRITTEN APPROVAL of Versico.
E. After completion of the installation, upon request, an inspection shall be conducted by a Technical Representative of
Versico to ascertain that the membrane roofing system has been installed according to Versico's published
specifications and details applicable at the time of bid. This inspection is to determine whether a warranty shall be
Thermoplastics 1/2023 5
issued. lt is not intended as a final inspection for the benefit of the owner.
F. Coordination between various trades is essential to avoid unnecessary rooftop traffic over completed sections of the
roof and to prevent subsequent damage to the membrane roofing system.
G. The solar reflectance of this roofing product may decrease over time due to environmental defacement such as dirt,
biological growth, ponded water, eti. The roof should be monitored at regular intervals and maintained or cleaned
when necessary to assure the maximum solar reflectance.
H. Refer to the Design Reference DR-07-20 'CRRC/LEED lnformation" for information. (i.e. solar emittance, solar

2.03 lnsulations/Underlayments
A. General
1. Roof insulation thickness must be determined by the thermal value required for each project and may be subject
to code approval limitations. On projects where a vapor retarder is used, the specifier must calculate insulation
thickness to ensure the temperature at the vapor retarder will not fall below the calculated dew point.
2. Multiple layers of insulation are recommended with all joints staggered between layers.
3. For minimum recommended R-Values, previously published by American Society of Heating and Air-
Conditioning Engineers (ASHRAE), consult local building code official for applicable requirements.
4. For lnsulation fastening pattern and densities refer to Versico Applicable Details and Design Reference DR-05-
1 9 "lnsulation Fastening Patterns".
5. When new insulation or cover boards are specified, the use of Versico lnsulation and Versico marketed cover
board is required. Any of the Versico lnsulation/Underlayment may be specified subject to design restrictions
included with each of the following tables.

GAUTION: Walking on the boards immediately after placement in adhesive can cause
slippage/movement until the adhesive has started to set up.
On roofs with a slope greater lhan 1l2" in 12", begin adhering insulation at the low point and
work upward to avoid sliPPage.
A person should be designated to walk/roll-in all boards and trim/slit or apply weight
as needed to ensure adequate securement.
3. Alternate attachment method, the specifier may select an alternate insulation attachment that incorporates a
solid mopping of the insulation with hot asphalt (ASTM D312, Type lll or lV). lf the attachment method is to be
covered by the Versico Warranty, Versico must be contacted for specific requirements. Upon review and
acceptance by Versico, the maximum warranty coverage available is limited to '15 Year with maximum Peak
Gust Wind Speed Coverage of 55 mph, for other warranties contact Versico.
a) Extruded or Expanded Polystyrene insulation are not acceptable when this alternate attachment method is
specified.
b) The existing gravel surfaced built-up roof must be scraped to remove all loose gravel. Large blisters that
may prevent continuous embedment of insulation must be repaired. The surface of the substrate must also
be dry and clear of foreign material.
c) On coal tar pitch, when deemed compatible by the specifier, minimum 1.5" Polyisocyanurate is the required
membrane underlayment when using darker heat weldable membranes (tan or gray). lf VersiWeld /
VersiFlex white membrane is used, minimum 1" thick Polyisocyanurate is required.
d) For successful attachment, proper asphalt temperatures must be maintained and the specifier's
requirements concerning the installation of a base sheet (where required) and quantity of hot asphalt must
be followed.
The maximum insulation board size shall notexceed 4'X4', Trim insulation boards around crickets and
saddles to ensure continuous embedment.
f) Caremustbeexercisedtopreventcontaminationofthetopsurfaceoftheinsulation. Asphaltoozingthro-ugh

VersiWeld / VersiFlex membrane.
S) A grid shall be installed subdividing the roof in individual sections of 24OA square feet. Required for
warranties up to 10 years with wind speed coverage up to 55mph.
h) The wood nailers are installed relatively flush with the insulation surface and the membrane is to be fastened
with seam fastening plates and Versico HPV or HPVX Fasteners on 12" o.c. For wood nailer installation,
refer to Design Reference DR-08-11 "Wood Nailers and Securement Criteria".
Mechanically Attached Roofi ng Systems
1. Versico Fasteners and Fastening Plates are required for insulation securement. Refer to lnsulation
Fastening Criteria Table in Paragraph 2.05 for appropriate fastener and deck penetration. The fastener can be
used with either 2-318" diameter HPVX/HPV-XL Plates OR 3" diameter lnsulation Fastening plate.
2. Any Versico approved insulation or cover board shall be mechanically attached to the roof deck at lhe
miriimum rate of 1 fastener and plate per every 8 square feet (4 fasteners in a 4 x 8 board) for warranties up
to 15 year. Projects with 20 yearwarranties require the use of 6 fasteners and plates in a 4'x 8' board ('1 per
5.333 square feet).
CAUTION: Versico Polyisocyanurate lnsulation with a thickness less than 1.5" installed over an
existing roofing membrane without a tear-off must be mechanically attached to the roof deck

3.05 Membrane Placement and Securement
Thermoplastics 1/2023 48
A. General
1. Ensure that water does not flow beneath any completed sections of the membrane system by completing all
flashings, terminations and daily seals by the end of each workday.
2. Sweep all loose debris from the substrate.
3. lf aesthetics are of concern, protection should be specified to avoid discoloration of the white membrane surface
resulting from adhesive residue or excess foot traffic.
4. ln addition to the primary membrane securement (Bonding for Fully Adhered and Fastening for Mechanically
Attached Assemblies), additional membrane securement is required at the perimeter of each roof level, roof
section, curb, skylight, interior wall, penthouse, etc., at any inside angle change where slope or combined slopes
exceed 2" in one horizontal foot, and at other penetrations in accordance with the applicable Versico details.
Refer to Paragraph F for additional membrane securement.
B. Membrane Placement
Maximum '12'wide VersiWeld or maximum 10'wide VersiFlex Membrane is fully adhered or mechanically attached
to an approved insulation or substrate.
1. position VersiWeld or VersiFlex membrane over the acceptable substrate. For a mechanically attached
assembly ensure the proper number of perimeter sheets are positioned along the perimeter of the roof as
outlined in Paragraph '1 .05 "Warranty Tables".
2. Position field sheets perpendicular to the steel deck flutes in Mechanically Attached Applications.
3. place adjoining membrane sheets in the same manner, overlapping edges appropriately to provide for the
minimum overlap width. lt is recommended all overlaps be shingled to avoid bucking of water.
C. Membrane Securement / Bonding - Fully Adhered Roofing System
1. Adhere VersiWeld or VersiFlex membrane to an acceptable substrate with Versico Bonding Adhesive. CAV-
GRlp 3V Low-VOC aerosol adhesive may be utilized with VersiWeld TPO membranes. CAV-GRIP PVC aerosol
adhesive may be utilized with VersiFlex PVC membranes (cannot be used with any KEE or KEE HP bareback
membranes). Comply with Labels, Safety Data Sheet (SDS) and Technical Data Bulletins for installation
procedures and use. Adhesive must be applied to both the membrane and the surface to which it is being
bonded.
2. On projects at high altitudes (6,000' and above), rapid flash-off (drying) of Bonding Adhesive and Primers will
occur due to low atmospheric pressure.
3. Fold membrane sheet back so half the underside is exposed. Sheet fold should be smooth without wrinkles or
buckles.
4. Stir Bonding Adhesive thoroughly scraping the sides and the bottom of the can (minimum 5 minutes stirring is
recommended). Bonding surfaces must be dry and clean.
S. Apply Bonding Adhesive to the exposed underside of the membrane and the corresponding substrate area. Do
n6iafpty Bonding Adhesive along the splice edge of the membrane to be heat welded over adjoining sheet.
When using VersiWeld Bonding Adhesive or VersiFlex Low-VOG Bonding Adhesive, a coverage rate of
approximately '120 square feet per gallon per one surface (membrane or substrate) or approximately 60 square
feet per gallon per finished surface (includes coverage on both membrane and substrate) shall be achieved.
eppiy aOnesive evenly, without globs or puddles with a plastic core, medium nap paint roller to achieve
continuous coating of both surfaces. A 9-inch roller will easily fit into the S-gallon containers.
A mechanical roller dispenser can be used to apply Bonding Adhesive when the continuous coating and
coverage rate noted above are maintained.
CAUTION: Due to solvent flash-off, condensation may form on freshly applied Bonding Adhesive when the
ambient temperature is near the dew point. lf condensation develops, possible surface
contamination may occur and the application of Bonding Adhesive must be discontinued. Allow
the surface to dry ind apply a thin freshener coat at the coverage rate which is approximately half
the coverage rate stated above to the previously coated surface when conditions allow for
continuing.
Thermoplastics 1/2023 49
NOTE: When Aqua Base 120 is specified refer to Spec Supplement G-09-'18 "Aqua Base 120 Bonding
Adhesive" for application methods and warranty requirements.
6. Allow adhesive to flash-off until it does not string but remains tacky to a dry finger touch.
CAUTION: Care must be exercised to ensure proper drying. Avoid thin areas of adhesive because over drying
can occur and proper adhesion may not be achieved.
7. Roll the coated membrane into the coated substrate while avoiding wrinkles.
B. Brush down the bonded section of the membrane sheet immediately after rolling the membrane into the
adhesive with a soft bristle push broom to achieve maximum contact.
g. HydroBond Adhesive can be applied directly to the substrate using an airless spray machine or a medium nap
roller. Do not apply HydroBond to splice areas to be hot-air welded. When applying HydroBond, ensure that the
adhesive has not dried before the membrane is laid in place. This is a wet lay-in adhesive; drying occurs rapidly
during high temperatures, and care must be taken to ensure the membrane is laid into wet adhesive. To ensure
a weilay-;n, adjust the application technique according to weather conditions. Avoid heavy or thin application of
adhesive. Rollthe membrane into the wet, adhesive coated substrate while avoiding wrinkles. lmmediately brush
down the bonded portion of the membrane with a soft-bristle push broom or a clean, dry roller applicator to
achieve maximum contact and to work out any air bubbles. lmmediately after brooming out from the center, roll
the membrane in all directions with a minimum 10G-150-lb (4M8 kg) weighted roller to achieve maximum
contact.
NOTE: When using Hydrobond Adhesive, do not apply when the surface and/or ambient temperatures are
below 40 degrees or when the temperature is expected to drop below 32 degrees within 72 hours of
application. Hydrobond Adhesive is a wet lay-in, one-sided adhesive with coverage rate is 100-133
square feet per gallon finished surface.
10. Fold back the unbonded half of the sheet and repeat the bonding procedures. Apply Bonding Adhesive to the
remaining exposed underside of membrane and adjacent substrate and complete this section as described
above.
1 1. lnstall adjoining membrane sheets in the same manner, overlapping edges a minimum of 2 inches to provide
for a minimum 1-112inch heat weld. lt is recommended that all splices be shingled to avoid bucking of water.
CAUTION: lf aesthetics are of concern, protect completed sections of the roof so Bonding Adhesive will not
discolor the membrane surface. Do not place Bonding Adhesive containers or their lids directly on
the surface of the VersiWeldA/ersiFlex membrane.
D. Membrane Securement / Fastening - Mechanically Attached Roofing Systems
1. Thermoplastic membranes shall be mechanically attached to the structural deck with specified Versico
Fasteners and designated Plates, for fastening densities and numbers of perimeter sheets refer to Warranty

3. On steel decks, membrane shall be positioned with seams perpendicular to the steel deck flutes. This allows the
external forces on the roof assembly to be distributed between multiple steel deck panels. Refer to Design
Reference DR-06-19 "Wthdrawal Resistance Criteria" in the Versico Technical Manual.
4. Perimeter Sheets
The number of perimeter sheets and fastener spacing is dependent on the building height, wind zone location
and warranty duration as outlined in Warranty Tables in Paragraph 1.05.
The roof perimeter is defined as all edges of each roof section (i.e., parapets, building expansion joints at
adjoining walls, penthouse walls, etc.). When multi-level roofs meet at a common wall, the adjacent edge of the
upper roof is treated as a roof perimeter if the difference in height is greater than '10'. Perimeter sheets are not
required at the base of the wall at the lower level.
NOTEI Expansion joints, control joints and fire walls in the field of the roof or roof ridges with slopes less than 3" to
the horizontal foot are not considered as part of the roof perimeter.
For VersiWeld membranes, perimeter sheets can be formed by using individual 4' to 6' wide sheets or by
sub-dividing 8'or 10'wide field sheet using 10" wide Pressure-Sensitive RUSS strip or row of seam
fastening piates as described below. For VersiFlex membranes, perimeter sheets can be formed by using
individual 40.5" or 5'-0" wide sheets.
a) lndividual perimeter sheets (TPO - 4', 5' or 6' wide)(PVC - 40.5" or 5' wide)(KEE HP PVC - 5' wide)
Position membrane along the perimeter of the roof over the acceptable insulation/underlayment. The
perimeter membrane width from line of securement to line of securement should be approximately 3'-6" to
4'-0" wide.
b) RUSS - Reinforced universal securement strip (versiweld Membrane only)
1) When field sheets are positioned parallel to a roof perimeter, 10" wide VersiWeld Pressure-
Sensitive RUSS (with 3" wide tape each side) shall be placed approximately down the center of the 8'-
0', 10'-0" or 12'-0" wide VersiWeld TPO field membrane sheets. When a RUSS divides a field sheet in
half, two perimeter sheets are created.
2) When field membrane sheets extend perpendicular to the edge of the roof, position the 10" wide
VersiWeld Pressure-Sensitive RUSS beneath the membrane along the center of each field sheet
extending a distance equal to 0.4 times the building height to create perimeter sheets.
GAUTION: 6" wide VersiWeld Pressure-sensitive RUSS is only available with 3" wide QA Seam
Tape on one side and therefore cannot be used to form perimeter sheets.
c) Fastening Plates Method
ln lieu of the RUSS securement method, position a row of seam fastening plates in the locations identified
in Paragraph 4.b.1 and 4.b.2, secure plates with appropriate fastener and overlay plates either 6" wide
Pressure-Sensitive TPO Cover Strip (TPO Only) overlay the plates as follows:
1) VersiWeld lnstallation - Warranties Up to 20 Years - 6" wide Pressure-Sensitive TPO Cover Strip or
6" wide VersiWeld membrane centered over the plates and heat welded to the field membrane. Seal
cut edges of TPO overlay with TPO Cut-Edge Sealant to seal any exposed scrim, cut edge sealant is
not required for PVC or KEE HP.
2) projects with Warranties greater than 20 Years OR VersiFlex projects regardless of warranty duration'
center 6" wide section of TPO/PVC/KEE HP PVC membrane (equal thickness to the deck membrane)
over the plates and heat weld the field sheets. All cut edges of TPO overlay must be sealed with TPO
Cut-Edge Sealant to seal any exposed scrim, cut edge sealant is not required for PVC or KEE HP.
NOTE: Perimeter sheets can also be formed by positioning RhinoBond plates placed along the
center of a field membrane (if heat induction welder is available on job-site). Refer to
"Attachment l" for additional information.
d) Building with Special Gonditions:
Air pressurized buildings, canopies and buildings with large openings where the total wall openings exceed
10% of the total wall area on which the openings are located (such as airport hangars, warehouses and
large maintenance facilities) will typically require additional perimeter membrane securement, an increased
Thermoplastics 1/2023 51
fastening densi$ or other enhancement.
e) Buildings with large openings
When any wall contains major openings with a combined area which exceeds 10% of the total wall area on
which the openings are located, four (4) perimeter sheets (centered over the opening) must be specified as
shown.
As an option to the above perimeter securement,
a fully adhered membrane section may be used in
lieu of the mechanically attached membrane at
large openings in accordance with the Versico
Specification for the VersiWeldA/ersiFlex Fully
Adhered Roofing System.
NOTE: Depth of perimeter area, noted above,
shall not be less lhan 2.5 times the
width of the opening.
f) Buildings with overhangs
The membrane must be specified with
perimeter sheets installed over the entire
overhang area extending onto the main roof
deck when at the same level.
As an option, a fully adhered membrane
section may be used in lieu of the
mechanically attached membrane at building
overhangs in accordance with the Versico
Specification for the VersiWeldA/ersiFlex
Fully Adhered Roofing System.

5. Field Membrane
a) Position adjoining field membrane sheets to
allow an approximate overlap of 5-112" al
those locations where Fastening Plates are
located (along the length of the membrane); at
the same time overlap end roll sections (the width of the membrane) a minimum of 2".
b) Secure the membrane at the approved fastening density with the required Versico Fastener and Fastening
Plates.
c) For installation of membrane with fullness, tighten the sheet between fasteners as follows:
'1) Unroll sheets and Position.
2) Place a fastener and plate in one end of the sheet on the appropriate fastener mark. Go to the opposite
end of the sheet, pull it tight and place a fastener and plate at the appropriate mark. Place the remaining
fasteners into the sheet.
3) Proceed to weld the sheet in place and continue across the roof.
6. Prevention of membrane distortion during windy conditions:
a) Unroll sheet approximately 5' and position edge of membrane with overlap line on adjacent sheet.
b) lnstall fasteners along the 5' exposed edge.
c) While the 5' of expgsed membrane is being fastened, begin welding the overlapped edge using the
Automatic Heat Welder.
Thermoplastics 1/2023 52
d) As sheet is being welded and fastened concurrently, unroll membrane. Unroll only enough membrane to
stay a few feet ahead of welding and fastening process. This reduces amount of unsecured membrane to
be distorted by wind.
e) Continue this process for each adjoining sheet.
VersiWeld QA (Quick-Applied TPO) - Quick-Applied Roofing System (membrane bonding)
10' wide VersiWeld QA TPO is fully adhered to an approved insulation or substrate with Factory Applied Quick-
Applied Adhesive.
1. Position VersiWeld QA TPO membrane over the acceptable substrate.
2. Fold membrane sheet back so half the underside is exposed.
3. Remove the release liner on one half of the sheet starting from the split in the liner at the middle of the sheet.
The liner should be removed at an angle to reduce risk of splitting or tearing.
4. Roll the membrane onto the substrate while avoiding wrinkles. To achieve the best adhesion, the membrane
should be rolled onto the substrate at an angle with 30" wide 150 lb weighted segmented roller. \Men applying
the VersiWeld QA TPO membrane it is recommended to maintain a large curve on the leading edge of the
membrane. This will help eliminate creases and bubbles that cannot be removed after the sheet is in place.
5. Fold back the remaining half of the sheet and repeat the above process.
Additional Membrane Securement
1. Securement must be provided at the perimeter of each roof level, roof section, expansion joint, curb, skylight,
interior wall, penthouse, etc., at any inside angle change where slope exceeds 2 inches to one horizontal foot,
and at all penetrations as identified on the Versico details.
2. Securement may be achieved as follows;
On Mechanically Attached Roofing Systems, Versico's HP\D( Fastening Plates are used to secure the
membrane with the appropriate Versico Fastener at the base of walls and penetrations and flashed as
shown on the applicable Versico detail (excluding OSB, cementitious wood fiber and gypsum decks where
the required Versico Fastener is installed with the associated 2" diameter plate). On Fully Adhered
Roofing Systems, Versico standard 2" diameter Seam Fastening Plates may be used in lieu of HPVX
Plates.
Securement of the membrane shall be a maximum of 12 inches on center. Starting 6 inches minimum to 9
inches maximum from the inside or outside corner.
c) On Mechanically Attached assemblies, additional membrane securement is required around pipes and
sealant pockets as shown on the applicable detail. The plates must be positioned a maximum of 12" away
from the penetration, spaced a maximum of 12" on center and flashed in accordance with the applicable
Versico Detail"
d) After securing the membrane, flash in accordance with the appropriate detail
3.06 Heat Welding Procedures
A General
1. APEEL Protective Film should be removed from within areas that are to be heat-welded together. ln areas that
do not require heat welding, the APEEL Protective Film can be left in place for up to 90 days.
2. Heat weld the VersiWeld or VersiFlex membrane sheets using the Automatic Heat Welder or Hot Air Hand
Welder and silicone roller.
3. When roof slope exceeds 5" per horizontal foot, use of the Automatic Heat Welding Machine may become more
difficult; use of the Handheld Hot Air Welder is recommended.
4. Gheck the surfaces of the membrane to be heat welded to ensure they are properly prepared.
The surfaces to be heat welded must be clean. Membrane overlaps that become contaminated with field dirt
must be cleaned with Weathered or PVG and KEE HP Membrane Cleaner (Weathered Membrane Cleaner
E
F
a)
b)
Thermoplastics 1/2023 53
should not be used to clean VersiFlex PVC). Weathered or PVC and KEE HP Membrane Cleaner should be
wiped dry with a clean Splice Wipe prior to welding. No residual dirt or contaminants should be evident.
B. Automatic and/or Handheld Heat Welder Equipment
Refer to Spec Supplement T-01-18 "Heat Welding Equipment" for:a) Temperature Settingsb) Equipment Set-upc) Additional lnformation
C. Membrane Welding
Prepare the Automatic Heat Welder and allow it to warm for approximately 5 to 10 minutes to reach operating
temperature.
2. Position the Automatic Heat Welder properly prior to seaming with the guide handle pointing in the same direction
the machine will move along the seam.
3. Lift the overlapping membrane sheet and insert the blower nozzle of the Automatic Heat Welder between the
overlap. Machine will begin moving along the seam immediately.
4. Weight plates provided on Automatic Welders must be utilized.
5. Proceed along the seam ensuring that the small guide wheel in front of the machine aligns with the edge of the
top membrane sheet. Guide the machine from the front only.
CAUTION: Ensure the power cord has plenty of slack to prevent dragging the machine off course (which could
result from a tightly stretched cord).
6. At all splice intersections, roll the seam with a silicone roller to ensure a continuous heat welded seam (the
membrane should be creased into any membrane step-off with the edge of the silicone roller). A false weld may
result due to surface irregularities created by multiple thicknesses of VersiWeldA/ersiFlex membrane sheets.
When using 60-mil or 80-mil VersiWeld or 80-mil VersiFlex Membrane, a TPO/PVC "T" Joint Cover must be
applied over all "T" joint splice intersections.
7. To remove the Automatic Heat Welder from the finished splice, disengage and pull the nozzle from the seam
area, the machine will stop automatically.
8. Mark the end of the heat welded seam with a water-soluble marker for easy identification. A Handheld Welder
will be necessary to complete the weld in the area between where the Automatic Heat Welder is stopped and
restarted.
9. Perform a test weld, at least, at the start of work each morning and afternoon. Test welds should be made if any
changes in substrate or weather conditions occur.
10. All membranes, at end laps, a minimum 6" wide, reinforced coverstrip must be used in conjunction with
applicable primer.
D. Preventing Membrane Creeping During Welding
I
1
The operator of automatic welding equipment must apply foot pressure to the membrane, keeping the
membrane tight under the welder. Refer to Spec Supplement T-01-18 "Heat Welding Equipment" for
additional information.
E. Test Cuts
Perform a test weld at least at the start of work each morning and afternoon. Refer to Spec Supplement T-01-
18 "Heat Welding Equipmenf' for additional information.
F Seam Probing
1. A cotter pin puller (blunt or dull for PVC or KEE HP Membranes) or Versico TPO Seam Probe is recommended
to probe all heat-welded seams. Probing seams must be done once heat welds have thoroughly cooled. Refer
to Spec Supplement T-01-18 "Heat Welding Equipment" for additional information.
Thermoplastics 1/2023 54
G. Gut-Edge Sealant
1. Apply Cut-Edge Sealant on all cut edges of the VersiWeld reinforced membrane (where the scrim reinforcement
is exposed) afterseam probing is completed. When a 1/8" diameter bead of TPO Cut-Edge Sealant is applied,
approximately 225 - 275linear feet of coverage per squeeze bottle can be achieved.
a) Cut-Edge Sealant is not required on cut edges of VersiFlex membrane (Horizontal or Vertical).
b) Cut-Edge Sealant is not required on vertical VersiWeld splices.
3.07 Welding Problems I Repairs
A Handheld Hot Air Welder and a 2" wide silicone roller must be used when repairing the VersiWeldA/ersiFlex
membrane. When the entire heat welded seam is to be overlaid, an Automatic Heat Welder may be used.
B. Prior to proceeding with any repair procedure, the area to be repaired must be cleaned with Weathered or PVC and
KEE HP Membrane Cleaner fl//eathered Membrane Cleaner should not be used to clean VersiFlex PVC or KEE HP
Membrane). The membrane can typically be repaired with standard cleaning methods. ln cases where the standard
cleaning method is not sufficient, the following procedures must be used.
1. Scrub the area to be welded with a "Scotch Brite" Pad and Weathered or PVC and KEE HP Membrane Cleaner.
2. Clean all residue from the area to be welded with a Splice Wpe or a clean natural fiber (cotton) rag.
3. Weld the new membrane to the cleaned area using standard welding procedures.
Voids in welded seams can be repaired using a Handheld Hot Air Welder and a silicone roller. Depending on
conditions, a splice overlay may be required.
Position the handheld welder facing into void so hot air is forced between overlapping membranes. Roll the top
membrane surface using positive pressure toward the outer edge until the heated membrane surfaces are fused.
Exposed scrim-reinforcement (resulting from scorching surface of membrane) and test weld areas must be repaired
by overlaying the damaged area with a separate piece of VersiWeldA/ersiFlex reinforced membrane with rounded
corners. The overlay must extend a minimum of 2 inches past the area to be repaired.
Probe all edges of the overlay once cooled to ensure a proper weld has been achieved.
Seal all cut edges of VersiWeld reinforced membrane with TPO Cut-Edge Sealant. Cut-Edge Sealant is not required
on cut edges of VersiFlex Membranes.
The same overlay repair procedures may be used for puncture in the VersiWeldA/ersiFlex membrane.
3.08 Flashings
A. GeneralGonsiderations
1. The height of new wall flashing must extend above the anticipated water level or slush line.
2. On 15- or 2O-year warranty projects, Versico's Termination Bar, in conjunction with Water Cut-Off Mastic, must
be specified under all metal counterflashings and surface mounted reglets.
3. To comply with various warranty options, flashing material must equal the required minimum membrane
thickness but shall not be less than 60 mils thick. For projects with 25 year or greater warranties Versico Pre-
Fabricated accessories must be used when feasible.
4. All Projects, regardless of Warranty Duration, shall incorporate Versico supplied pre-fabricated accessories to
seal pipes, corners, sealant pockets, etc., when feasible. When field fabrication is required, the flashing material
shall not be less than 60-mils thick.
5. For wall and curb flashing, the required thickness shall equal the deck membrane thickness.
On Retrofit Projects
Bitumen-based roof cement and asphaltic-based flashing material, if allowed to remain in contact with the
membrane, will cause severe membrane discoloration and for PVC and KEE HP membranes, promote
premature plasticizer migration. Existing wall and curb flashing must be removed or concealed with a new

a) The specifier must examine structural supports for rooftop equipment to determine if reasonable access to
the membrane beneath the equipment is provided. Versico should be consulted for clarification when
access to the membrane system will be restricted.
b) When hot pipes or other similar penetrations exceed 140"F (60"C) (PVC/KEE HP) or 160"F (71"C) (TPO),
they must be designed to incorporate an insulated metal collar and rain hood designed to maintain a surface
temperature less than 140'F (60'C) (PVC/KEE HP) or 160"F (71"C) (TPO).
When possible, all reinforced membrane splices are heat welded with the Automatic Heat Welder. The Hand
Held Hot Air Welder should be utilized in hard to reach areas, smaller curbs, vertical splices and when using
non-reinforced mem brane.
a) The new VersiWeldA/ersiFlex membrane flashing must not conceal weep holes or cover existing
throughwall flashing.
b) lnstall surface mounted reglets and compression bar terminations directly to the wall surface.
ln areas where metal counterflashing or surface mounted reglets are used as vertical terminations, the
counterflashing must be sealed with a rubber grade caulking to prevent moisture migration behind the new wall
flashing.
8.
B.Application of Bonding Adhesive
1. Membrane shall be fully adhered to vertical surfaces with VersiWeldA/ersiFlex Bonding Adhesive. CAV-GRIP
3V low-VOC aerosol adhesive may be utilized with VersiWeld TPO membranes. CAV-GRIP PVC aerosol
adhesive may be utilized with VersiFlex PVC membranes (cannot be used with any KEE or KEE HP bareback
membranes). The Bonding Adhesive shall be applied continuously, without globs or puddles.
2. Allow adhesive to flash-off until it is tacky but will not string or transfer to a dry finger touch.
3. Roll the membrane into the adhesive.
4. Care must be taken when setting the flashing to avoid bridging greater than 3/4 inch at angle changes (i.e.,
where a parapet or roof penetration meets the roof deck). This can be accomplished by creasing the membrane
into the angle change.
5. Terminate the edges of the installed membrane in accordance with Versico's applicable details.
6. When using TPO membrane flashing only, bonding adhesive is not required when the flashing height is 12" or
less. When Versico termination bar is used beneath the counter-flashing, bonding adhesive can be eliminated
when the flashing height is 18" or less.
C. Walls, Parapets, Gurbs, Skylights, etc.
The flashing height must be calculated so that the VersiFlex membrane flashing includes a minimum 1-1i2 inch heat
weld beyond the Fastening Plates.
1. Fasten at angle change as identified in Paragraph 3.05 F, Additional Membrane Securement, with the required
Versico Fastener and Plate.
2. Flash the fasteners/plates with a separate piece of VersiWeldA/ersiFlex reinforced membrane; apply heat and
crease the flashing into the angle change before attaching it to the vertical surface.
D. Metal Edge Terminations
Factory-fabricated metal edge systems must be secured to the wood nailer as specified by the manufacturer. Shop-
fabricaied edging must be installed in compliance with appropriate Versico Detail using Versico TPO/PVC Coated
Metal in orderto achieve ES-1 Compliance. Refer to the appropriate Universal Details for other flashing options and
requirements.
E Roof Drains
1. VersiWeldA/ersiFlex membrane may extend into the drain sump when the slope of the sump is less than 3" to
one horizontal foot.
Thermoplastics 112023 56
When the drain sump is greater than 3" to one horizontal foot, additional membrane securement must be
installed.
2. Only drain strainers that have been approved by the specifier in accordance with applicable codes may be used.
F. VersiWeld/VersiFlex Rib Profiles
VersiWeldA,/ersiFlex Rib Profiles are recommended for use with VersiFleece TPO and PVC adhered roofing
systems.
2. The VersiWeldA/ersiFlex Rib Profiles should be positioned parallel to the laps of the installed TPO/PVC roofing
system and parallel with the roof slope where possible.
3. Ensure that all welding surfaces are clean and dry. lnspect all seam areas for proper weld prior to installing
VersiWeldA/ersiFlex Rib Profi le.
4. Rib Profile spacing can be individually determined to achieve the desired appearance.
5. Connecting multiple ribs is achieved by using fiberglass pins. lnsert a pin half-way into the end of one profile.
Connect the adjoining rib by inserting the exposed end of the pin into the alignment hole. Repeat previous steps
for additional TPO/PVC Rib profiles.
6. Consult the VersiWeld or VersiFlex Rib Profile installation guides for instructions on proper installation
techniques.
G. Other Penetrations
On Mechanically Attached assemblies, additional membrane securement is required around pipes and sealant
pockets as shown on the applicable detail. The plates must be positioned a maximum of 12" away from the
penetration, spaced a maximum of 12" on center and flashed in accordance with the applicable Versico Detail.
1. Pipes, Round Supports, etc.
a) Flash pipes with Molded Pipe Flashings or Split Pipe Seals where their installation is possible. Molded pipe
flashings cannot be cut and patched; deck flanges cannot be overlapped or installed over angle changes.
b) Where Molded Pipe Flashings or Split Pipe Seals cannot be installed, APPLY FIELD FABRICATED PIPE
FLASHING using VersiWeldA/ersiFlex non-reinforced membrane.
2. Flexibte Penetrations (braided cables, conduits, wires, etc.) must be enclosed in a stable "goose neck." Apply
a Split Pipe Seal or field fabricated pipe flashing to flash the goose neck.
3. Hot pipes that exceed 140'F (60'C) (PVC/KEE HP) and 160'F (7'1'C) (TPO), must utilize an insulated metal
collar and rain hood, flashed with a field fabricated pipe flashing.
4. For pipe clusters or unusually shaped penetrations, a Molded Sealant Pocket and White One-Part Sealant
must be utilized.
5. Existing Roof Tielns for PVC or KEE HP PVC membranes require total isolation between the two roofing
systems. For TPO membranes refer to applicable Versico details for tie-ins.
6. Flashing of Difficult Penetrations, referto Spec Supplement G-'11-20 for "LIQUISEAL Liquid Flashing" for
additional information and specific requirements.
H. APEEL Protective Film (Optional)
When the optional APEEL Protective Film is utilized on TPO or PVC/KEE HP, remove and discard the APEEL
Protective Film after the installation of the entire TPO or PVC/KEE HP Roofing System is complete.
3.09 Roof Walkways
Walkways are to be specified at all traffic concentration points (i.e., roof hatches, access doors, rooftop ladders, etc.),
and if regular maintenance (once a month or more) is necessary to service rooftop equipment. Refer to Spec
Supplement G-05-l8 "Roof Walkway Installation".
Thermoplastics 1/2023 57
3.10 Daily Seal
On phased roofing, when the completion of flashings and terminations is not possible by the end of each workday,
provisions must be taken to temporarily close the membrane to prevent water infiltration. Refer to Spec Supplement G-
06-20 "Daily Seal & Glean Up".
