Proiect Information:
Height = 8' Exposure: C Basic/Ultimate Wind Speed: V i=163 mph
Length = 37' Category: II Nominal Wind Speed: V.d=V it*40.6
Width = 15' Slope: < 7° (asd = allowable strength design)
Parapet Wall: N/A Residential KZ = 0.85, Kzt = 1.0, Kd = 0.85
Design Calculations:
Velocity Pressure: q = 0.00256*K K tKdV2
Velocity Pressure (u): q=0.00256(0.85)(1.0)(0.85)(163)2 = 49.14 psf
Velocity Pressure (.d): q=0.00256(0.85)(1.0)(0.85)(163*40.6)2 = 29.49 psf
Width of Pressure Coefficient: 0.1(15') = 1.5'
0.4(8') = 3.2' ) use: TO"
Effective Wind Area: <1 Off
For parapet height three feet (3') or larger, zone three (3) shall be treated as zone two (2).

All Area Roofing - Franklin Residence
Flat Wood Non Insulated Roof Deck
400 E. Weatherbee Road; Fort Pierce, FL:
Design Pressures Based on Vasd:
1) Field
2) Perimeter
3) Corners
Attachment Requirements:
P1 = 29.49*[(-1.0) — (0.18)] = -34.8 psf
P2 = 29.49*[(-1.8) — (0.18)] = -58.4 psf
P3 = 29.49* [(-2.8) — (0.18)] = -87.9 psf
The system is acceptable as approved based on the requirements of Florida Product
Approval # FL1654-R23, Appendix 1, page 26 of 65, System No. W-170 with a
maximum design pressure of -90 psf.
Base Ply:
Self adhere one or more plies of Elastoflex SA V Base Ply sheet to the min. 15/32"
plywood deck.
Cap Ply:
Torch apply the Polyflex G Cap Ply sheet to the base ply sheet.
Notes: Corners and perimeter area dimension shall not be less than a = 3'0"
Contractor to verify that the fastening patterns meet manufacturer's
requirements for issuance of a warranty (as applicable).
