A shingle roof can last anywhere from 15 to 30 years. While you can extend its longevity by repairing minor issues as soon as they arise, a complete roof replacement will eventually be necessary. When that time comes, you’ll have to choose between the tear-off method and the overlay approach. Naturally, each process has its own advantages, and the best option for the job will depend on the circumstances. Below, learn about each method to see which is right for your home. 

What Is the Overlay Approach?

During the overlay method, roofing contractors apply a second layer of shingles directly on top of the first. This is a viable way to reinforce a worn roof that doesn't necessarily need total replacing. Because the job calls for considerably less labor and materials than total roof replacement, it’s fairly affordable. It can also be completed relatively quickly, and oftentimes in a single day. It’s important to note that the second layer of shingles will add additional weight to the roof, so an overlay can only be performed once. If your roof already has two layers of shingles, you’ll have no choice but to opt for the tear-off method. Otherwise, it will threaten the structural integrity of your home. 

What Is the Tear-Off Method?

As the name implies, the tear-off method entails tearing off the old roof before replacing it with a new one. This approach is recommended for roofs that have sustained considerable damage over the years and may no longer be structurally sound. While the tear-off method costs more and takes additional time because of the extra work, it can be a worthwhile investment because a brand new roof will last a lot longer than shingle overlays. This is primarily because a single layer of shingles traps much less heat than a double layer, and excessive heat causes shingles to curl. This will cause them to deteriorate faster.
