Another way inexperienced contractors try to cut costs on roof installation is by roofing over old felt. When a roofing company takes off the existing roof, it should completely remove all of the old shingles and felt underneath.
Roofing felt (also known as tar paper) was originally made from recycled rags, but now is made from recycled paper products like cardboard, saw dust, polyester, or fiberglass that is soaked in a waterproof substance. This felt is a durable material that provides protection between the wooden sheathing and the exterior shingles. Roofing felt also protects the shingles from the resins that are produced from the roof’s wooden sheathing. Roofing felt gives the roof a cleaner and more professional look and acts as an extra layer of protection against fire.
When we install a new roof, we remove all pre-existing shingles and old felt to ensure your roof will be in the best condition possible. We first start by installing the new felt. New felt comes in rolls of 36-inch wide material, and we lay it down so that each strip overlaps the others. If water or snow leaks onto your roof, we want it to slide down the felt paper. While installing roof felt may seem like an easy process, it should be done with great care and only by a professional roofing company.
If you do not properly remove all the old felt, then can cause a worse problem than originally anticipated. Ultimately, roofing felt is an inexpensive layer of protection that will help your home in the long run. Cutting corners on roof installation may save you money now, but it will come back to haunt you later. Learn how you can get a free quote on your next roofing job with Robbins Roofing.
