Union County Roofers: Article About Roofing Felt
When a new roof is installed, most expert Union County roofers will first install roofing felt over the roof deck before adding the shingles. While some homeowners may not know why roofing felt is needed, there are some major advantages to this addition.
Initially, roofing felt was designed to protect the home against water penetration while the home was being built or while new shingles were being installed. Essentially, the felt provided protection to a roof that had been stripped of its old materials. It also protected the internal roofing materials from rain in between the time of the tear off and the installation.
Not all roofs have roofing felt installed. However, there are certain advantages to having this material applied before the new shingles are added. In addition, keeping the roof deck dry in the event of a rainstorm during the installation of new shingles is always ideal. During the actual installation process, the felt provides a safer working environment, as the material is much less slick than the roofing deck alone. The roofing felt also provides a moisture barrier between the shingles and the roof deck while potentially increasing the fire rating of the overall roof system.

There are cases where a thicker felt may be required. Most homes require a standard number 15 felt. On roofs that have a steep pitch, a number 30 felt may be used, as this type of felt resists tearing. This increases the safety for roofers who are working on steep roofs as well. However, it should be noted that thicker felt does not increase water resistance.
While there certainly are benefits to installing roofing felt, it should be noted that roofing felt is not necessarily an essential component. Not all roofs need this material. When the shingles are installed, the roofing nails actually go through the felt and into the roof decking. If the shingles are not installed properly and leaks occur, the roofing felt is not going to stop the leaks. However, before choosing to not have the felt installed, homeowners should check local building codes, as many require that roofing felt be installed.
In many cases, manufacturers consider the roofing felt to be an essential part of the roof and require that it be installed in order to meet warranty requirements. Even though roofs that do not have roofing felt often last just as long with proper maintenance, it is still recommended to install the felt for the safety of the roofers and for temporary protection.
