Some roofing contractors choose to install a new roof over existing asphalt shingles in an attempt to expedite the installation process. However, this can lead to quite a few issues and might even increase repair costs in the long run. Here’s what you need to know about a roof tear-off and why it’s the preferred method.

What Is a Roof Tear-Off?

A roof tear-off involves removing existing materials from a roof and starting with a clean slate. Roofers always peel off the asphalt shingles and sometimes the underlayment and decking, depending on the materials’ conditions. Contractors are sometimes reluctant to perform a tear-off due to the time and effort involved, and many homeowners are also hesitant due to the added costs.

Roofs can typically only handle two layers of asphalt shingles, although even that may be pushing it. When more layers of shingles are added, numerous problems can occur. For example, any leaks that were present on the existing roof will still cause problems after the new one is installed. Adding new shingles over old ones also increases the weight, which damages the structure below.

Why Is It Recommended?

Lasts Longer

With a tear-off, you’re starting fresh with a brand-new roof. That means your roof system will likely last longer since the process helps address underlying issues.

Fixes Leaks & Defects

Missing shingles and other roof defects allow water, air, and pests into your home. Once your roof is completely removed, roofers can identify and repair defects in the decking or underlayment.
