Even homeowners who are very picky about the brand of roofing shingle they prefer forget about what's underneath that shingle: underlay, or roofing felt. Few people, and even some roofing contractors from my experience, understand the purpose the of underlay. Yet, the roofing underlay design, specification and installation can have a big impact on the functionality of your new asphalt shingle roof New York and an impact on moisture in your home. Talk to your roofing installer Bronx about the types of underlay available for your roofing system New York. It is an important element of your fiberglass or asphalt shingle roofing Queens.
The roofing underlay should allow water vapour to pass freely through, and prevent water penetration into the building structure and insulation. Roofing felt is designed to hold condensation formed overnight on the underside of roofing materials and release it as vapour during the day. It is also a secondary layer of protection if your asphalt single roof Bronx fails, allowing rain, dust, wind, and moisture through. It also protects the insulation in your attic. With all these factors, your asphalt shingle roof replacement Queens or other shingle roofing should include careful consideration of the proper underlayment for your roofing material and climate.
