Why are "Ice and Water" roof membranes always "peel-and-stick" ???
Roofers I've talked to say that re-roofing a house that had an ice and
water membrane put on it 10 or 15 years ago is a pain. Ripping the old membrane off frequently leads to replacing parts of the plywood deck. I don't understand why these Ice and Water membranes have to be "peel and stick". Seems they would work just fine if you rolled them out and put a few nails on them to keep them in place before the shingles go down (ie same as tar paper). Does anyone make an Ice and Water membrane that's NOT peel and stick? (Tamko Nail Fast seems like it but Tamko doesn't exactly call it an Ice and Water shield even though it's made of the same SBS material). |
