I’m reaching out to see if you can help answer a question regarding the roofing membrane for this project. We typically use GAF products and would like to confirm whether they are approved for use on this project.

07/21/2026

The membrane installed must be compatible with the existing roof pvc membrane to ensure a watertight tie in where it may meet portions of the roof that will not be replaced. The product used must be compatibal pvc membrane roofing and must not compromise performance or manufacturers warranty. See SOW paragraphs1.E.

and 2.E.

The insulation is specified as both R30 and 7" minimum. R30 is equal to 2 layers of 2.6" ISO (total of 5.2") while 7" would equal R41. We just need to clarify what to install. 07/21/2026

The minimum R-value required is R30. The thinnest insullation over the roof shall meet this requirement.

The scope states that the ISO should be mechanically fastened but doesn't clarify how to install the cover board and membrane. Both the cover board and the membrane can be installed by either mechanical fastening or adhesion. I recommend adhering them which provides a better hail resistant assembly.

07/21/2026

The cover board and membrane shall be fastened by both adhesion and mechanically. Pine Ridge experiences extremely high wind events.

IHS COR

A0001 4 7/19/2026 Technical

Cover board is readily available in both 1/4" and 1/2" thick boards but the spec does not specify a thickness. I recommend 1/2" as it provides better hail resistance at only a slightly higher cost. 07/21/2026

1/2" cover board shall be installed

IHS COR

A0001 5 7/19/2026 Technical

The spec calls for replacing the parapet flashings. Does this include the existing metal coping cap? The existing metal coping is in good condition and could be reinstalled once the new membrane is installed on the walls.

This would easily save $10,000 - $15,000 in material costs alone. 07/21/2026

If the contractor can guarantee replacement of any metal coping cap that is bent or damaged as a result of its removal and re-installation, then re-using the coping cap will be acceptable.

Concerning the warranty, we offer various warranties including the 15 year specified in the specification. I recommend clarifying that the Duro-Last 15 Year NDL (No-Dollar-Limit) Supreme warranty is required. In addition to covering the material and labor for 15 years this warranty also covers consequential (interior) damages, all at no extra charge! (See attached warranty sample.)

07/21/2026

See revised SOW paragraph 2.B. for warranty requirements.

Is there interest in sustainability? Duro-Last has a "Recycle Your Roof" program (see attached flyer) and the EPDM and ISO could be repurposed through a company called "Repurposed Materials" (repurposedMATERIALS - Largest Industrial Thrift Store in America )

07/21/2026

The contractor is responsible for the disposal of the roof membrane, insulation, and all other removed materials as required by this project.

The method of disposal is not specified. IHS COR
