Roofing felt is a layer of asphalt saturated paper that is usually used as an extra protective covering against inclement weather. They are installed beneath the shingles and help in preventing water from seeping into your home. Waterproofing your home with roofing felt is essential if you use asphalt, wood, or shingles as your primary roofing material. An advantage of using roofing felt is that it can be cut to the desired length in case you want to replace just a part of it. There are a number of factors that you need to consider before attempting to install roofing felt on your own.
Mentioned below is some more information on roofing felt. This information may assist you in your efforts to keep your home well maintained.
What is roofing felt?
In short, roofing felt is a paper/cardboard that is saturated with asphalt and impregnated with tar and bituminous coal. There are other types of roofing felts that are coated with either sand or abrasive materials which ensure that the felt does not stick to itself when rolled up. The sand also helps to keep the asphalt coating on the paper, protecting the roofing felt from inclement weather conditions.
They are commonly used as waterproofing agents for your roof. They prevent humidity or moisture from seeping through in the event of shingles getting damaged. It might only be one layer but it certainly is important in protecting your interiors from water damage. The roofing felt goes underneath other layers like shingle. This is partially because this material does not deal too well with exposure to the elements.
When it comes to dimensions roofing felts can be customised according to your requirements. The thickness can also vary with the most common ones being 15lb or 30lb, 3 feet wide and 150-300 feet long. It is prudent to purchase extra material in case some of it gets damaged during installation.
