Roofing felt has two sides, the smooth side and the rough side. When laying shingles on your roof, you should place the rough side of the felt on the roof. Felt is often called an underpayment, and it’s required when you install asphalt shingles as the first layer of the roof. You’ll also need roofing felt if you’re installing asphalt shingles over wood shingles or a built-up roof.
The first layer of roofing feel should be installed at the bottom corner of the roof, so that its bottom edge will sit flush with the roof’s drip edge. To install the second layer of roofing felt, use fasteners every four to eight inches. Leave the top part of the felt free. Trim the ends of the roofing felt with a utility knife. Start a new roll with the ends overlapping about four inches.
After you’ve cut the first layer of roofing felt, install the second roll. Install the second roll the same way, by placing it on the roof’s edge. Fold the felt paper over the peak and staple the first layer to the second roll’s downward slope. When you’re finished, you’ll have a two-inch overlap on the top and bottom of the roof. Afterwards, you can cut the remaining felt paper with the utility knife.
Felt is a waterproof, breathable membrane for your roof. It is commonly sold in rolls of fifteen to thirty pounds per 100 square feet. Manufacturers of felt typically offer warranties of at least 10 years. Keeping your shingles well-maintained can extend its life. This is also referred to as tar paper, as it is infused with bituminous material. While it might be a petroleum-based product, the best way to protect your roof from damage is to avoid using tar paper altogether.
If you’re using roofing felt on a shed roof, you need to purchase a sufficient amount. It’s essential to calculate the area of the roof and purchase enough felt. Once you’ve purchased the required amount, you can unroll the roofing felt on a flat surface and cut it with a sharp hook blade knife. Once you’ve cut the roof felt, you’ll need to clean it with a bristle brush. Next, you’ll need to apply a coat of primer or waterproof paint.
