Roofing question...shallow pitch underlayment question.
Part of our home has a very shallow pitch. It's just steep enough for shingles though. Code is to 1/2 lap(?) with 30 lb. felt and is the absolute minimum required for a shallow pitch. One contractor said that he would heat seal rubber with a torch and another said that they would apply a peel & stick product. Which of these three methods would be the best? The peel & stick man said that the torch sealed rubber was an inferior product and had a manufacturer's warranty of only 10 years as opposed to the 30 year shingles that would be applied. Would that matter if this product is underneath he shingle?
Any experiences? thank you!
