Question Submitted on September 4, 2009 by Crowther Roofing

Question: “Upon review of the specification section 07 51 13, Built-up Asphalt Roofing, we found under section 2.2 Fiberglass Felt Materials, a. Venting Base Sheet. The wrong material is specified. The ASTM D 4897, Type II is designed for high moisture content substrate, and not over the type used on this project. It is also designed to be mechanically fastened or spot mopped to the substrate, and not mopped solid. The proper Fiberglass Base Sheet is the ASTM 4601, Type II product. I have attached product data sheets on these two products.

You can also apply four piles of the Ply Felt in lieu of the base sheet, which the manufacture’s would rather see.”

USACE Response to Question: The Venting Base Sheet should be ASTM D 4897, Type II as specified. USACE has specified the correct product for the application.
