Dallas Roofing: Article About Installing Asphalt Shingles
Asphalt shingles are among the most popular roofing materials among homeowners. They are inexpensive, can last or up to 20 years and easy to install. However, if they are not installed correctly, they could rot, buckle or blow off with ease. This is why a Dallas roofing professional should always be called in to handle such a project.
The first step to installing an asphalt shingle is to put down the underlayment and flashing. These materials will prevent water from getting into the roof deck or into the home while the shingles are being installed. Additionally, they will provide protection against water after they have been put on the roof.
Once the underlayment has been put down, it is time to install a starter strip. The starter strip should be sealed to the underlayment with cement or another strong adhesive that will repel water. After this initial strip has been put on, a contractor will use chalk to make install lines on the roof. These lines are generally 5 inches apart to allow the shingles to overlap.
Contractors generally have two methods for getting the shingles on the roof so that they can be put into place. First, they may be lifted onto the roof with a crane or another lever and put into their proper location to be secured to the underlayment.

If the roof has a low enough slope, the shingles may be carried to the roof by hand. It is usually faster and easier for a contractor to be able to carry materials to the roof.
Three tab shingles come in sections of three 12 inch shingles that are attached to the roof deck with roofing nails. Typically, four nails are sufficient to keep a shingle in place. However, it may be a good idea to use six nails in areas that experience extreme winds. While nails can be installed by hand, most professionals will use a nail gun to get the job done faster and to ensure that each nail is hammered in with the same amount of force.
Once the shingles have been put on the roof and secured into place, the final step is cleanup. It is important that old shingles are removed from the yard below as they could cause damage to grass or plants if left unattended. Asphalt shingles may also release pollutants into the air, which is why they should be bagged and removed from a homeowner's property as soon as possible.
