How to attach roofing felt is the first step in making sure that your roof stays in good condition. Roofs are subjected to many different weather elements such as wind, rain, snow, hail, and even ice. Each of these has the potential to cause damage to the shingles. No one wants to have their roofing material deteriorate so quickly. By learning how to install roofing felt on your own, you can protect your roof from all types of weather elements.
The most common type of roofing material is asphalt shingles. If you have a flat roof or a slope that is more than 8 degrees, then asphalt shingles will probably be best for you. Asphalt shingles are water-resistant underlayments made with asphalt, a by-product of crude oil production. In addition to being water-resistant, asphalt shingles provide a solid barrier between the concrete slabs and the underlying roof structure. This reduces the risk of water seeping into your roof and accumulating underneath the shingles.
To install roofing felt on a slope, you will need a long straight razor blade and a construction paper (stainless, black, unpolished). Use the long blade and scrape off the excess coating. You will probably need to do this several times to ensure a smooth and flat surface for the felt.
If you have asphalt shingles on a slope that experiences moisture, then you will need to remove some of the asphalt before you begin work on the roofing felt. First, locate the ridge cap and remove any debris that may be there. You can use a pressure washer to eliminate the moisture. Once the area is dry, you can apply the roofing felt and nail it into place, using the supplied nails.
To install roofing felt over a roof decking which has been damaged by hail or weather, you will need to build an insert prior to beginning your work. With the insert in place, you can install the roofing felt and nail it in place, but only after you have attached the roof decking and built up some of the damage. The added bulk around the insert will prevent the roofing felt from sliding.
To complete installing the roofing felt, you will need to add three to four rows of nails. Nail the felt to the roof decking first, and then attach the next set of shingles. Continue in this fashion until all of the shingles are in place. Now, you just need to wait for the final set of nails to be installed. These should run along the entire length of the shingles to prevent moisture penetration.
