Why Is A Roof Tear-off Necessary? Can You Just Leave Your Old Roof Underneath?

November 17, 2022

As Class A contractors, we always suggest a complete tear-off of the old roof for our clients. But is that necessary? Can't you leave the old stuff there and put new shingles on top to help the client save a few bucks? It turns out it is a much better investment down the line to do a full tear-off. Below, we've outlined why this step is critical to protecting your home and wallet.

While it may seem like a good idea to lay down shingles over your existing roof, there are several reasons why a complete re-roof is a better option. Adding another layer of shingles on top of your existing roof adds more weight. This added weight can stress certain parts of your home, potentially from your roof down to the foundation, which can cause costly damage down the line.

Even if both layers are installed perfectly straight and flat,there is a likely chance they'll begin shifting anyway after a few years.Virginia's heavy winds and storms and a climate where temperatures fluctuate quite a bit from season to season can cause issues. Any moisture trapped below those new layers could start seeping through gaps between them into spaces where it shouldn't belong—like inside your attic! Additionally, it isn't the prettiest look for your Richmond area home, decreasing your curb appeal and potentially your home value.  

Tear-off is a critical part of the re-roofing process because it allows a better installation of the new roofing materials. When we peel back all the layers and look at the roof's structure, we may see serious issues that need to be fixed. Problems like rot, mold and hidden leaks can cause severe damage to the roof decking, rafters, the ridgeboard, and more. It also ensures that you will comply with insurance companies and warranty requirements. Many home insurance companies won't cover a home with several roof layers. We only work with quality roofing supply companies that provide materials with generation-long warranties. Still, those warranties are contingent on being applied correctly, an aspect we pride ourselves on within our company. The first step to that is a complete tear-off. If you have any concerns about replacing your entire roof, consider the investment in upgrading. You will savemoney down the road, ensuring every part of your new roof is in tip-top shape!

By taking this vital step, you will save money in the long run by extending the life of your home. Have more questions and want to chat? Our team would love to help answer any questions you may have!
