Dear Sir;
SCANNED

St. Lucie County
The re -roofing specifications for flat areas of the subject commercial property are
reviewed by myself. The purpose of this letter is to determine the wind uplift pressures
and specify attachment of self -adhered base sheet.
The existing flat roof is located in Exposure D area at mean roof height of 18 ft. The roof
consists of 19132" CDX plywood deck, having positive drainage. Roof design
pressures; as per 2014 Florida Building Code, ASCE 7-10, 165 MPH ultimate Wind
Velocity for Risk Category II in Exposure D area, using Wind Load Factor of 0.6 for ASD;
are determined as follows:
Field P1= -52 psf / Perimeter (4' wide) P2 = -87 psf / Corner (4'x4') P3 = -131 psf.
The proposed Polyglass Self -Adhered Modified Bitumen Roof System over Wood
Decks (#FL1654-R21) consists of sealed plywood seams using 4" wide ElastoFlex SA-V
Plus tapes followed by roll -pressed ElastoFlex SA Plus base and SIBS SA cap sheet.
The max. design pressure of -135 psf (Wood Deck, Non -Insulated, Table 1G, Syst Type F,
Syst#W-145, pg. 21/56) is determined to satisfy roof uplift pressures in all roof zones.
Therefore, this letter is to certify that installation of Polyglass Self -Adhered Roof System
(#FL1654-R21) over wood decks, as described above, conforms to requirements of 2014
Florida Building Code which specifies 165 MPH ultimate wind velocity for Risk Category
II in Exposure D area.
If you have any questions regarding this matter or I may be of further assistance, please
do not hesitate to call me.
Sincerely, d 1

The existing flat roof is located in Exposure D area at mean roof height of 18 ft. The roof
consists of 19/32" CDX plywood deck, having positive drainage. Roof design
pressures; as per 2014 Florida Building Code, ASCE 7-10, 165 MPH ultimate Wind
Velocity for Risk Category II in Exposure D. area, using Wind Load Factor. of 0.6 for ASD;
are determined as follows:
Field Pi = -52 psf / Perimeter (4' wide) P2 = -87 psf / Corner (4'x4') P3 = -131 psf.
The proposed Polyglass Self -Adhered Modified Bitumen Roof System over Wood
Decks (#FL1654-R21) consists of sealed plywood seams using 4" wide ElastoFlex SA-V
Plus tapes followed by rolled -pressed ElastoFlex SA Plus base sheet and SBS SA cap
sheet.
The max. design pressure of -135 psf (Wood Deck, Non -Insulated, Table 1G, Syst Type F,
