Peculiar Phenomenon - Pulling Shingles Off of Plywood | Dura Grip Sealant on Timberline HDZ Shingles
Remember the last time this happened on one of your roofs? Yeah, we couldn’t either and GAF is on millions of rooftops so I think we would have heard something about this rather peculiar phenomenon. So why do some shingle manufacturers make such a fuss about nails, nail placement and reinforcement tapes while completely ignoring the critical role that sealant plays in wind performance? Well, instead of a benchtop sales demo we went to this highly regarded hurricane research facility to show you it’s not all about the nails. Dura Grip™: available on all GAF Shingles, including our new Timberline® HDZ™ Shingles. Learn more at gaf.com/layerlock
