A Simple Step-by-Step to Replace the Seals
So, here is what you want to know: How do you replace asphalt roof materials, from tear-off to new roof installation?
Step 1: Ripping Off the Old Roof
Roofers begin by taking off all existing shingles and underlayment to access the roof decking. That’s the only way to check for hidden damage, such as rot or mold.
Step 2: Inspecting the Decking
The roof deck, usually plywood or OSB, is carefully examined if replaced. Any weakened or rotted spots are removed and replaced to give added support to the new roof.
Step 3: Install the Underlayment and Flashing
The protection against water comes from a waterproof middle layer made of a synthetic material or felt. Flashing is also employed around chimneys, vents, and valleys to discourage water from pooling in vulnerable areas.
Step 4: Applying Starter Shingles
The starter course of shingles is laid along the eaves to resist the wind lifting the exposed edges of the roof.
Step 5: Install the New Shingles on the Roof
Shingles are lapped and nailed according to the manufacturer’s application instructions. Correctly aligned and spaced text is important for appearance and performance.
Step 6. Ridge Cap and Final Sealing
Ridge cap shingles sit at the roof peaks as the final piece for a polished look and added defense. Roofers seal nails and inspect all transitions.
Step 7: Clean Up And Final Check Up
Debris is swept away, magnetic rollers collect errant nails, and the site is given a thorough scrubbing. The last step is an inspection to make sure everything is up to code and quality.
