1.02 General Design Considerations
Various Warranty 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.
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.
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.
Metal-Edge Systems and Copings should be designed in compliance with Section 'l 504.5 of the lnternational Building
Code and shall be tested in accordance with ANSI/SPRI ES-1 .
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.
It is the responsibility of the specifier to review local, state and regional codes to determine their impact on the
specified Versico Roofing System.
It is the responsibility of the building owner or his/her designated representative to verifu 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 pro1ects, 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
Design Reference DR-O1-21 "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 tiltup 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.
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
B.
c
D.
E.
F.
G
4Thermoplastics 1/2023
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 rooflng 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. Tapered 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 'l18" 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.
J. 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" diameter
holes every 100 square feet in the existing built-up roof or single-ply membrane (excluding non-reinforced PVC
membrane).
3. If 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.
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
representative 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 (Directory 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 rooflng 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.
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.
The solar reflectance of this roofing product may decrease over time due to environmental defacement such as dirt,
biological growth, ponded water, etc. The roof should be monitored at regular intervals and maintained or cleaned
when necessary to assure the maximum solar reflectance.
Refer to the Design Reference DR-07-20 "CRRC/LEED lnformation" for information. (i.e. solar emittance, solar
reflectance and recycled content)

2.03 lnsulations/Underlayments
A. General
1- Roof insulation thickness must be determined by the thermal value required for each project and may be subjectto code approval limitations. On projects where a vapor retarder is used, the specifier must calculaie 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-oS-
'1 9 "lnsulation Fastening patterns".
5. When new insulation or cover boards are specified, the use of Versico lnsulation and Versico marketed coverboard is required. Any of the Versico.lnsulation/Underlayment may be specified subject to design restrictionsincluded with each of the following tables.

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.
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
Adhere VersiWeld or VersiFlex membrane to an acceptable substrate with Versico 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). 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.
5. Apply Bonding Adhesive to the exposed underside of the membrane and the corresponding substrate area. Do
not apply Bonding Adhesive along the splice edge of the membrane to be heat welded over adjoining sheet.
When using VersiWeld Bonding Adhesive or VersiFlex Low-VOC 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.
Apply adhesive 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 and 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.
8. 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.
9.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 wet lay-in, adjust the application technique according to weather conditions. Avoid heavy or thin application of
adhesive. Roll the 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 (45-68 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 1-112 inch 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 dlrectly on
the surface of the VersiWeldA/ersiFlex membrane.
D. Membrane Securement / Fastening - Mechanically Aftached Roofing Systems

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.
NOTE: 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 plates as described below. For VerslFlex 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'-A" 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€ensitive 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 Conditions
Air pressurized buildings, canopies and buildings with large openings where the total wall openings exceed
1Oo/o 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

B. Prior to proceeding with any repair procedure, the area to be repaired must be cleaned with weathered or pVC andKEE HP Membrane Cleaner (Weathered Membrane Cleaner should not be used to clean VersiFlex pVC or KEE HpMembrane)- The.membrane can typically be repaired with standard cleaning metntos.- tn cases where the standardcleaning 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 \A/ipe or a clean natural fiber (cotton) rag.
3. Weld the new membrane to the cleaned area using standard welding procedures.
c Voids in welded seams. can be repaired using a Handheld Hot Air Welder and a silicone roller. Depending onconditions, a splice overlay may be required.
D' Position the handheld welder facing into void so hot air is forced between overlapping membranes. Roll the topmembrane surface using positive pressure toward the outer edge until the heated r6mbrane surfaces are fused
E' Exposed scrim-reinforcement (resulting from scorching surface of membrane) and test weld areas must be repairedby overlaying the damaged area with a separate piecl of versiweldA/ersiFlex reinforced membrane with roundedcorners. The overlay must extend a minimum of 2 inches past the area to be repaired.
F. Probe all edges of the overlay once cooled to ensure a proper weld has been achieved.
G' Seal all cut edges of VersiWeld reinforced membrane with TPO Cut-Edge Sealant. Cut-Edge Sealant is not requiredon cut edges of VersiFlex Membranes.
Note: 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 20-year wananty projects, Versico's Termination Bar, in conjunction with Water Cut-Off Mastic, mustbe specified under all metal counterflashings and surface mounted regiets.
3. To comply with various warranty options, flashing material must equal the required minimum membranethickness but shall not be less than 60 mils thick. F-or 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 toseal pipes, corners, sealant pockets, etc., when feasible. When field taOricaiibn is iequired, tne flasning materiatshall not be less than 60-mils thick.
5. For wall and curb flashing, the required thickness shall equal the deck membrane thickness.
6. On Retrofit Projects
Bitumen-based roof cement and asphaltic-based flashing material, if allowed to remain in contact with themembrane, will cause severe membrane discoloration Lnd for PVC and KEE Hp membranes-, promotepremature plasticizer migration. Existing wall and curb flashing must be removed or concealed with a new
Thermoplastics 1/2023 Ss
acceptable substrate.
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.
B. Application of Bonding Adhesive
7
8.
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-'112 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-
fabricated edging must be installed in compliance with appropriate Versico Detail using Versico TPO/PVC Coated
Metal in order to achieve ES-1 Compliance. Refer to the appropriate Universal Details for other flashing options and
requirements.
E. Roof Drains
VersiWeldA/ersiFlex membrane may extend into the drain sump when the slope of the sump is less than 3" to
one horizontal foot.
Thermoplastics 1/2023 56
2.
When the drain sump is greater than 3" to one horizontal foot, additional membrane securement must beinstalled.
Only drain strainers that have been approved by the specifier in accordance with applicable codes may be used.
F. VersiWeld/VersiFlexRibProfiles
1. VersiWeldA/ersiFlex Rib Profiles are recommended for use with VersiFleece TPO and pVC adhered roofingsystems.
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 adjointlO 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 sealantpockets as shown on the applicable detail. The plates must be positioned a maximum of 1'2;, away from thepenetration, spaced a maximum of 12" on center and flashed in accordance with the applicable Versico Detail.
1. Pipes, Round Supports, etc.
a) Flash plpes 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 plpE
FLAS H I NG using VersiWeldA/ersi Flex non-reinforced mem brane.
2. Flexible 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 (71"C) (TPO), must utitize an insutated metat
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 Tie-lns 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 (Optionat)
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. itefer to SpecSupplement G-05-18 "Roof Walkway lnstallation".
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 infiitration. Re-fer to Spec Supptement G-
06-20 "Daily Seal & Clean Up".
