The first step of a roof installation is to determine what type of roofing is necessary for the job. Some roofing materials are designed to be installed over a specific area, such as a flat roof or an angled roof. A metal roof is another option. Before choosing a type of roofing material, you should consider the type of climate in which you live.
Professionals will install a new roof with safety in mind. They will set up roof jacks with large boards to create landing platforms for workers and to catch falling shingles. They will also install safety harnesses and straps for workers to protect them from falling objects or from weak spots on the roof. This can prevent accidents and injury.
Many problems with a roof can be traced back to improper roof installation. Improper attic ventilation is another cause of roof failure. Trapped air can affect the lifespan of a roof and void the manufacturer’s warranty. If not repaired immediately, an improperly installed roof can fail in as little as two years. Other signs of improper roof installation include lifted shingles, sideways nail heads, and nails that don’t have the right pressure.
Installing the drip edge is another step in roof installation. It goes over the underlayment and overlapping the edge is essential to ensure an effective seal. While you’re installing the drip edge, make sure to do so carefully to prevent cutting the underlayment. You can install the drip edge by working from the bottom gable and working upward. You can use tin snips to trim the edge to the proper size. In addition to following the proper installation process, be sure to keep your roof clean and free of debris.
Once you’ve secured the required permits, you can move forward with installing the new roof. The installation phase typically lasts two to four days. It may take longer if there are unforeseen circumstances, so be sure to allow enough time for planning and inspection. The roofing company will perform an inspection of your current roof before starting work on your new roof. They will also provide you with a scope of work and secure the necessary permits.
After you’ve completed the preparation, you can begin installing shingles. The first shingles that go down are called starter shingles. They are half the width of regular shingles, and are used to prevent water from leaking in between the shingles. The shingles should be installed in an overlapping pattern. Make sure you nail each shingle securely with a nail gun.
Lastly, you need to choose the kind of felt paper to use. Felt paper will protect the shingles underneath and increase the roof’s fire rating. You can find a variety of materials at a roofing supplier, including 15 and 30-pound felt. The 30-pound felt is safer to walk on and wrinkles less.
