systems that are not addressed in FRSA/TRI April 2012 (04-12) and are used in foam -on tile applications.
Maximum Design Pressure is the result of testing for wind load resistance based on allowable wind loads,
and reflects the ultimate passing pressure divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has
already been applied). Refer to FRSA/TRI April 2012 (04-12), Appendix A, Table 1A or FBC 1609 for
determination of design wind loads.

6 3, . LeakBarrier® MS300 PS200"T, PS200Mu, NRS00"' or SS400 Ice and`Water Armor:
6.3.1 Shall be installed in compliance with the requirements for ASTM D1970 underlayment in FBC Table
1507.1.1 for the type of prepared roof covering to be installed.
6.3.2 Non -Tile Applications:
Cut to manageable sections and allow to relax prior to application.
Membrane Application:
➢ Place a full width piece on the prepared substrate, aligned parallel to the eave edge and extend
approximately 3/8" over the eave and rake with the selvedge edge positioned upslope.
➢ Fold back the upslope half of the sheet and remove the exposed release film, taking care not to displace
the membrane
➢ Working from the centerline out, roll the membrane onto the substrate, taking care to avoid wrinkles
and ridges
➢ Apply a 1/16" thick layer of asphalt plastic cement over the eave and rake metal, extending 2" to 3"
onto the deck surface.
➢ Fold back the downslope half of the sheet, remove the release film and roll the membrane onto the
substrate from the centerline out.
➢ Seal all 6" end laps with a 1/16" thick application of asphalt plastic cement and stagger all end laps
minimum 36".
➢ Remove selvage release film, if present, and install second and subsequent courses in a similar manner.
➢ Install capped or tin -tagged nails 6" D.C. along the centerline of the laps.
➢ At all T-joints, where an end -lap and the next overlapping course intersect, apply a bead of roofing laps
cement before the overlapping course is laid.
➢ Roll the entire surface with a weighted roller, paying particular attention to side laps, end laps and eave
/ rake areas to ensure a complete bond.
6.3.3 Tile Applications (PS200"T only):
Reference is made to FRSA/TRI April 2012 (04-12) Installation Manual and Table 1 herein, using the
instructions noted above as a guideline.
Wait a minimum of 24 hours prior to loading roof tiles.
For mechanically fastened tile roofing over 2-ply system, consisting of Base Sheet and self -adhering top
sheet(s), Base Sheet fastening shall be not less than FRSA/TRI April 2012 (04-12), Table 1.
For adhesive -set tile applications, refer to Section 5.6.4 herein.
Refer to Section 5.8 for tile staging limitations. If tiles are to be left in a staged condition for more than 30
days, Tarco Roofing requires tiles be staged two tiles perpendicular to slope, four tiles on top, parallel to
slope, regardless of the allowance in Section 5.8.
6.3.4 Multi -Ply Underlayment Systems:
LeakBarrier® SS400 Ice and Water Armor followed by LeakBarrier® SS400 Ice and Water Armor (direct -to -
deck per 5.6.1 or over mechanically attached base sheet per 5.6.2) is allowable for use under mechanically
attached prepared roof systems. Limits of use are those associated with the top -layer material. This is not
a requirement, but is allowable if a multi -ply underlayment system is desired.

6.4 Tarco 15 arid 30:
6.4.1 Non -Tile Applications:
Shall be installed in compliance with the codified requirements for ASTM D226, Type I (Tarco 15) or ASTM
D226 Type II (Tarco 30) underlayment in FBC Table 1507.1.1 for the type of prepared roof covering to be
installed.
6.4.2 Tile Applications (Tarco 30 only):
Tarco 30 is limited to use as a mechanically attached base sheet in the "Two Ply System" from FRSA/TRI
April 2012 (04-12). Reference is made to Table 1 herein, coupled with FRSA/TRI April 2012 (04-12)
Installation Manual.
6.6.2 Non -Tile Applications:
Place a full width section of EasyLay, parallel to the eave edge of the roof and unroll 2 to 3 feet with the lay
lines facing up, and position to the edge of the eave and rake. Install a few fasteners at the top, near the
rake, and roll out the sheet to a manageable length. Pull, straighten and align the sheet so that any
wrinkles are eliminated and the sheet is even with the eave edge. Fasten with 3/8" headed roofing nails or
1" capped (plastic or metal) nails, driven by hand or pneumatically, spaced 6" o.c. at all laps in the center
of the seam area, and two staggered rows fastened 12" o.c. in the field of the sheet. Install nails such that
the head of the nail is flush with the surface, without cutting into the surface. Fasten from the top to
avoid walking or kneeling on unsecured sheet. Continue to the end of the substrate and fasten down.
Align the next roll over the preceding sheet so as to form a minimum 4", water -shedding lap, and install
per instructions above. Apply subsequent sheets in the same manner, with minimum 4" water -shedding
laps and minimum 8" end -laps, which are staggered minimum 36" fro the preceding course.
For double layer applications, follow the instructions noted above, but using a minimum 19", water -
shedding side lap.
Allow for minimum 6" up the vertical transitions and minimum 6" over hips and ridges.
At valleys, first install a vertical length of EasyLay down the center of the valley, then start at the low point
and work to the high point, rolling the membrane from the center outward in each direction, ensuring no
wrinkles or tears. Covered with valley -metal or other valley lining material in accordance with NRCA
recommendations.
Apply a thin coat of asphalt plastic cement to waterproof areas where any cuts or tears have occurred.
Seams or joints that require adhesive or sealant can be treated with high quality plastic cement (asbestos
free).
6.6.3 Tile Applications, base laver in multi -ply system:
LeakBarrier EasyLay is limited to use as a mechanically attached base sheet in the "Two Ply System" from
FRSA/TRI April 2012 (04-12). Reference is made to Table 1 and Section 5.6.4 herein, coupled with

of battens or nail -boards, to prevent tile sliding and/or damage to the underlayment during the loading
process.
