How to Install Roofing Felt on an Asphalt Deck
Installing roofing felt is a process that differs slightly from installing asphalt shingles, but it is not impossible to do. Many people prefer to use it as a substitute because of its appearance and durability, as well as its fire retardant properties. Here’s how to install roofing felt. This process can be done by anyone who knows basic home repair skills.
The first step is to locate the gable edge next course from where the ridge line starts to divide the house into two parts. On each side of the ridge line, there will be a cutout. You should be able to see the cutout clearly from where you are standing. Once you’ve located it, you can begin to cut the exposed gable side insulation with a utility knife and utility blade. Keep in mind that there may be small spaces between the tack and the wall so be sure that you get these spaces covered with a piece of foam or a good quality drop in spacer.
Once you’ve located the cutout, pull off the insulation from the sheet. If there are no gutters, there should be a section of roofing nails around the baseboard near the ridge. Start nailing the sheet over the nails and be careful of the nails, so that they don’t pull the insulation loose. You will probably want to anchor the sheet in place with roofing nails that are slightly bigger than the screws.
Once you’ve attached the sheet to the existing roofing tar, pull off the felt and cut it again to make sure that the felt doesn’t leak through to the gable end. If it does, make sure that you have the gable end covered as well. Cut another piece of felt about twice the width of the sheet and just as long as your original size. Nail the second piece of felt along one edge of the gable end. This will help keep the felt inside the roof instead of on the ridge.
The final step is to pull on your roofing nails and begin to unroll the felt on the ridge. Keep in mind that you will probably need to work at an angle so that you can secure the shingles at each point. Once you have all the shingles secured, continue to roll the felt up and down the ridge. Make sure that you don’t forget any nooks and crannies along the way. If at any point you find any water or moisture, you should double check your installation and try again.
Installing a new roof over your existing roof is a very complicated project and may require some professional help. However, if you follow these steps, you should be able to successfully complete a roof installation even if you are not experienced with this type of repair. The key to a successful installation is using the right kind of roof shingles, laying your new deck correctly, and including a sealant for your asphalt deck.
