Overlay Versus a Tear-Off And Re-Roof

Overlay Versus a Tear-Off And Re-Roof

When it’s time to replace your existing roof, one of the biggest decisions you face is what type of shingle to install. There are many options, including an asphalt 3-tab shingle, an architectural shingle, an impact-resistant shingle and COOL shingles. We are Owens Corning certified preferred roofers and we encourage you to make the best-educated decision for your family. However, this is not the only decision that you have to make. Another is deciding whether to overlay your new roofing materials over your existing roofing materials or whether to tear off your existing roofing and have a new roof installed. Here is more information about an overlay versus a tear-off and re-roof.

What Does It Mean to Overlay Or Tear Off and Re-Roof?

Understanding the difference between an overlay and a tear-off and re-roof can help you to decide which option is ideal for you. Overlaying a roof means that your existing roofing material, typically shingles, is left in place. A new layer of shingles is applied over the top to help protect your roof from the elements once again. With a tear-off and re-roof, your existing roofing materials are removed, leaving nothing but the roof decking or sheathing. A new layer of roofing materials is laid on top of the roof decking or sheathing, giving you a completely new roof. We do not recommend an overlay roof installation. The buildup of heat dramatically degrades your new shingles and voids the warranty.

What Are the Benefits of Each Option?

One of the biggest benefits associated with an overlay is that it’s typically cheaper and faster than a tear-off and re-roof. This may be an option for someone on a tight budget or someone who needs a roof replaced quickly in the middle of winter. Even though you may have a new roof, don’t expect the shingles to last as long as a single layer installation. If repairs are needed on overlay roofs, a roofer has to tear through layers to find the problem. This isn’t an issue with tear-off and re-roofs.
