What plays a bigger role in preventing shingle blow-offs — the nails or the adhesive? GAF decided to find out by blasting 153 MPH hurricane-force winds at a roof held together with no nails — just GAF Dura Grip™ Adhesive. We’d never recommend installing a roof without nails, but after watching this video demonstration, the next time someone talks about their pretty nailing strips, you might want to ask, “Where’s your Dura Grip™?”

How tough are GAF shingles? According to this recent extreme shingle testing demonstration, they’re tough enough to withstand hurricane-force-winds, more water than any rainstorm will hit them with, and a continuous blast of red hot embers. GAF Advanced Protection® Shingles with GAF Dura Grip™ Adhesive are engineered to endure. See for yourself!
