I am about to finalize my roofing contractor and have a question regarding using Peel/Stick such as GAF Stormguard as the underlayment over the entire roof.
Will this protect the roof in the event of a high wind shingles being blown off? Second, how does this effect moisture that may get trapped between the sheathing and Stormguard underlayment, can the roof still breath? I have now the option of cover it all with stormguard, or cover the sheathing seams with 6" peel/stick then cover with 30# felt or titanium.
The cost of the entire covering with Peel and stick runs the cost up(28 sqs) but may or may not be usefull in the long run?
I am going to use Landmark 30yr shingles, certainteed starter and cap products. Shingles to be 6 nailed.
