New low-slope roof systems explained. Here's all the detailed information you need to stay current with the big increase in usage of single-ply and modified bitumen membranes and the unique problems they present. It's all in the third edition of The Manual of Built-Up Roof Systems, by C. W. Griffin and Richard Fricklas. Updated with a wealth of research and code updates from Hurricanes Hugo, Andrew and Iniki, the guide gets you up to speed on all the essentials--roof system performance, emerging materials, drainage, wind uplift, vapor control, fire resistance, thermal insulation, reroofing, and much more. And you'll even find field-tested solutions for such current roof system problems as lap-seam failures, membrane shrinkage and fastener backout.
