How Is a Roof Installed?

Blogs How Is a Roof Installed?

In this article, we are going to describe a process of a typical roof installation for our customers. You'll be able to understand the process better and find a good contractor for your installation. A moderately-sized, professional roofing job might take only 3 or 4 days and consists of the following steps.

1. Removal of existing shingles

Damaged and old shingle, as well as the old valley, flashing, and drip edging, need to be removed at the first step. A roofing crew will use tarps to protect the foundation during tear-off and will use magnetic tools to pick up nails and metal objects from your yard.

2. Minor repairs

Minor roofing repairs might need to be performed after the first step in order to provide a stable foundation. This might include replacing bad wood with new plywood.

3. Installing ice dam protection

The ice guard membrane is a synthetic waterproof material used in roofs to prevent water from backing up under the shingles and penetrating through the sheathing, where the moisture can get into your home and cause severe water damage.

4. Installing asphalt roofing paper

The roofing paper is usually installed over the roof sheathing and creates an inner barrier against water coming into the house. Rows of roofing paper need to be installed in an overlapping manner as they progress upward toward the peak.

5. Applying metal drip edging

Metal drip is installed around the edge of the roof, both the eave sides and gable sides, and nailed in place over the roofing paper or ice dam protection.

6. Checking a valley flashing

The flashing along with areas where two roof planes meet have to be properly isolated, protected, and sealed with roofing caulk.

7. Installing the roof material

Tab shingles are now installed, starting at the edges of the roof and working upward toward the peak.

8. Installing flashing around the elements

The flashing should be installed around all areas where roofing features penetrate the roof — against the chimney, around skylights and stack vents.

9. Installing the ridge vent

The ridge went will help the air circulation in the attic by exhausting hot air and preventing winter ice dams. If this option is not available for your roof type, there should be other types of roof or gable vents installed to provide air circulation in the attic space.

10. Clean up and final inspection

Cleaning up the debris is the last step of your roof installation. Now you can enjoy your new roof!
