Steps in the Roof Installation Process
Depending on the climate, a roof in a mild or moderate climate may only need one layer of underlayment, whereas a colder climate may require two layers of underlayment. Underlayment is a thin waterproof membrane that is applied to the decking of the roof, extending up to two feet beyond the interior wall line. The edge of the roof is capped with a drip edge flashing, which must be securely fastened to prevent water from leaking through the underlayment.
The next step in the roof installation process is to install the roof vents. These are installed with the proper flashing and may be single or double along the ridge of a roof. Excessive heat in the attic can cause the shingles to break down prematurely. These roof vents can be installed in conjunction with the installation of new shingles. For optimal ventilation, it is advisable to install roof vents in strategic places around the home, such as the eaves and roof eaves.
Roofing valleys require special treatment. Flashing is usually made of zinc, copper, lead, or aluminum. Proper installation is essential for proper flashing. Moss and algae growth can cause discoloration in the roof and need to be eliminated. A zinc flashing is an effective way to kill these organisms. Once the flashing is installed, the shingles can be placed on the roof. The final step in the roof installation process is to install the gutters.
In order to avoid injuries during the roof installation process, it is advisable to hire a professional. A professional roofer will set up roof jacks with large boards that serve as landing platforms for workers and fall-off shingles. The roof jack will also enable the worker to use a safety harness or strap to prevent falling objects from a weakened point on the roof. Finally, the roof installation process will ensure that all the workers are properly protected by a sturdy and stable structure.
Besides roof shingles, asphalt shingles are also the cheapest and easiest roofing material to install. These roofs are common throughout the U.S., and the best roof installers will also be able to repair them if necessary. However, the quality of the asphalt shingles and the workmanship are the factors that determine the roof’s lifespan. To ensure quality, it is advisable to hire an experienced roof installation company. Once the installation is complete, an independent roof installation company will provide a two-year labor warranty, and an optional 25-year warranty. This warranty will cover repairs and leak repair.
Roofing contractors will inspect the structure of your home and the surrounding area before starting the roof installation process. They will check the overall condition of the roof and the shape of the house. They will assess whether it is time for a roof reroof and whether the materials are still in good condition. They will also evaluate whether the existing roof sheathing needs to be replaced before re-roofing your home.
