Roofing Underlayment

Roofing underlayments are used as secondary barrier under shingles in residential roofing in order to prevent leaks and damage to decking and internal structure prior to shingle application. Roofing underlayments, in effect, help to protect our valuables from the effects of extreme weather. Before construction begins, talk to your builder and roofing contractor about incorporating these products for complete protection.
