Composite Roofing Installation Process

When you have a roof installed, you want to make sure that it's installed well so that it lasts a long time. Finding a contractor that has a lot of experience and is able to provide a quality roofing job is one of the easiest ways to increase the lifespan of your roof. However, you won't be able to tell how effective the contractor is at installing composite roofs unless you know the process yourself.

Install the Underlayment

The first step in the roofing process is for the underlayment to be installed. This is a water-resistant or waterproof layer that goes directly beneath the roof. It helps protect the house from leaks and inclement weather. Ordinarily, the underlayment is secured to the roof using staples or tacks, although in areas where there are high winds, plastic strips are used. When the underlayment is installed across the roof, it should be perfectly flat, have at least 4–5 inches of overlap between pieces, and directly in line with the sides of the house.

Prepping the First Row of Shingles

The next step is to get the first row of shingles ready for use. This is done by simply cutting off the tabs of the shingles that will be used for the first row with a utility knife. Removing these tabs is necessary to keep any moisture from being trapped underneath the shingles. 

Lay the First Row of Shingles

When laying shingles, you should always start at the eaves and work your way down in order to provide the maximum level of protection. Starting underneath the drip edges will make the process go more smoothly because you will not have to force any of the shingles into place. Galvanized nails should be used to secure each roofing shingle into its correct location, with the first row overlapping the eaves by about half an inch. 

Install the Rest of the Shingles

Once the first row has been installed, the rest of the roof will go up rather quickly. About a sixteenth of an inch needs to be left in between the shingles, with the labs overlapping the underlayment. Lay the shingles row by row until the rest of the roof is covered. If there are oddly shaped spaces, it is important that the shingles are cut to fit these spaces exactly in order to prevent moisture from seeping in.
