Why use roofing felt?

The felt helps keep water away from the wood, so it doesn't leak into the attic or into the house.


felt can be a lifesaver during extreme storms, heavy rains and snow. Even if you lose a tile, the felt provides an additional layer of protection for the roof covering. Roofing felt is a subfloor that is located between the roof covering and the shingles.

Its main purpose is to serve as another layer of protection against rain, wind and snow. As a result, contractors install it on the deck before fixing the roof shingles. Roofing felt refers to a tar paper. A layer of this tar paper is usually applied on a roof before the installation of roofing shingles.

The main purpose of this installation is to ensure that your roof is water resistant. In other words, you won't have to worry about water leaks from the roof because it provides an extra layer of protection. Before roofing contractors were so commonplace, this kind of blanket was designed to protect the internal structure of a roof during lengthy DIY roofing projects. Installation is also much easier with roofing felt, because it is safer to stand than a smooth plywood platform, especially for roofs with steep slopes.

For this reason, some inspectors and roofing professionals are skeptical about the essential nature of felt paper. For roofers, synthetic roofing felt is much safer during installation because there is a gripping surface that prevents slipping or falling. This coating serves as a moisture protection and can improve the fire resistance of a roof if left in place. If there is a leak coming from the roof, the felt paper could trap moisture before it moves into your home.

In many cases, workers replacing a roof use felt paper as a protective barrier before installing shingles on a roof. When it was first introduced, roofing felt acted as a temporary waterproof solution that protected the house while the roof was being built. This is due to self-adhesive technology combined with proven mechanical fastening; roofers save time and at the same time offer the highest quality materials and confidence in the finished product. The base of the roof can be left uncovered for short periods, but it must still be completely dry before you can add shingles on top.

While there is a fairly wide acceptance of this form of roof protection, there are several theories that suggest that this felt paper is unnecessary and sometimes even harmful to a roof. The same problems that arise with overheated roofs could arise with the use of felt paper as a roof subfloor in the Atlanta area. A professional roofing installation will most likely be fine without the use of felt paper if other measures are taken, although any work would be safer for roofers if felt paper were part of the project. Divide your roof area by the area of the felt rolls you plan to use and leave 10% more waste.
