If you are about to replace your roof, it’s a good idea to understand the basics of roof installation before beginning the project. There are several steps involved, including replacing damaged sheathing and installing new felt, which serves as a moisture barrier between your home and the outside environment. You’ll also need to consider the cost of felt.
The first step in installing shingles on a roof is to measure the area of the roof and lay out the layout for the shingles. The shingles should overlap to protect the roof from water dripping off the roof. You can create a template on a flat surface using chalk and tape. Use a chalk line every six inches to guide your placement.
It is important to follow the instructions carefully and follow the proper method when mounting the shingles on the roof. Failure to follow the proper procedure can lead to water leaks and other issues. It is also important to prepare the area and have the right tools and equipment. Before beginning the installation, ensure that the roof is free of debris.
The first row of shingles should be placed on the first course, so that it overlaps the previous course. It should have an overhang of five inches. After installing the first course of shingles, you should add the second course. The first row of shingles should be nailed flush to the previous one. You should also install roofing nails according to the manufacturer’s instructions. Depending on the region of your roof, you may need to use six roofing nails per row.
Underlayment is an important component in ensuring the water tightness of a roof. It is placed over the plywood decking and creates a barrier between the roof and the weather. Underlayment is a fabric containing asphalt or another water-repellent material. It varies in weight depending on the geographic region, but on average, underlayment weighs about 15 pounds.
When laying underlayment, start at the lowest part of the deck and work upward. The type of underlayment you use will determine the slope of the roof, the temperature at which it should be installed, and the types of fastening that you can use. Self-adhering underlayment must be cut to size and primed with an ASTM D41 asphalt primer before being installed. Water-based acrylic primers are also an option.
The underlayment works in conjunction with the flashings and the shingles. It must be installed in the correct order and in the correct orientation. Felt is sometimes used to align the shingles, but it will wrinkle when wet. During the installation process, the roof deck should be completely cleared of nails and debris.
Roof damage can have a wide range of consequences, and repairing it immediately is crucial. Even a small leak can lead to bigger problems over time, including mold, framing rot, destroyed insulation, and even damaged ceilings. One homeowner was left with a huge repair bill due to a small leak that was easy to detect, but went unnoticed for two years. The homeowner could have avoided this problem and saved himself a lot of money by fixing the leak as soon as it began.
Wind is another common cause of roof damage. High-speed winds can rip off shingles, causing extensive damage to a roof. Depending on the damage, a replacement roof may be needed. For more details visit a local McKinney roofing contractor in your area.
