How to install roofing felt, the latest product on the roofing industry, is gaining popularity fast. No longer do you have to settle for the pre-fabricated shakes that are so common and so boring. The felt that you are about to purchase will be custom fashioned and will come with all of the colors and textures that you can imagine. These roofing nails have been a part of the residential and commercial roofing markets for decades and were originally created by the Romans.
If you are interested in learning how to install roofing felt then you need to know a little bit about it first. Installing the felt is a fairly straightforward process as long as the directions are followed correctly. If you are unable to follow the instructions completely then you may find yourself having to strip off the old roofing felt prior to starting the installation.
For instance, if your roof deck has sloped roofs then you will want to install the roofing felt on the inside edge of the valleys. To accomplish this you must have an overlap of at least three valleys. For roofs that have flat roofs however you will want to overlap the areas where the flat roofs meet the slopes. This is where the real application of the overlapping can take place.
The basis of how to install roofing felt is quite simple. You will first want to build an open layer of either asphalt shingles or tar paper. The purpose of the open layer is to create a waterproof barrier between the sloped roof and the dirt. Once you have the asphalt shingles built, you will want to place the tar paper over the top. Then you will want to make an area where the asphalt shingles will be cut into. This area should be six to twelve inches away from the top of the tar paper and in direct line with the top of the sloped roof.
The key to how to install roofing felt is to have the tar paper or asphalt shingles be ahead of the sloped roof insulation. This will allow the underlayment to be set into place and adhere to the roofing felt. When installing the underlayment be sure to have the same thickness throughout. This will provide a strong base for the tar paper underlayment. Then you will want to run the drip edge felt under the tar paper and to overlap the spaces between the sloped roof and the felt.
Most people like to use the roll roofing felt underlayment for their roofing felt installation. However, it is possible to install the underlayment directly to the roofing felt. For the easiest installation of the roll roofing felt, you will want to follow the manufacturer’s direction. They will guide you through the entire process and provide a step by step method.
