Ice and water shield is a great product. If the roof is ventilated then why should there be a problem. The attachment to the roof would only be a concern, and yes, Ice and water shield does have a sticky side and when it gets hot it sticks. I know that sometimes when I have applied it, it did not "stick" right away and maybe because of the low temperature when I was doing it.
If it is sticking right away, putting it on is and "art". I would leave the plastic wrapping on it, and roll out the product with the plastic on the roof. With one top corner stapled you can sneak the plastic barrier out and the product sticks well without problem. Hard to describe......I have used it extensively........ jloomisconstruction.com
Considering using Ice and Water shield on the entire roof of my house in Fla. Is this advisable? Roof is ventilated well. Is it worth putting the membrane on in regards to possible hurricane damage to shingles? Thanks for replys.
