2 Reasons Your Roof Shingles Are Buckling

A roof shingle is designed to lay flat against the surface of the roof. In fact, if the shingle has any areas of buckling or bumpiness — it's not doing its job. All it takes is a tiny opening for moisture to get inside the underlayers of a roof and cause significant damage. If your shingles aren't resting flat on your roof, it's essential that you get to the bottom of the problem. Learn some of the reasons why this problem might be affecting you.

1. Too Many Layers

For specific roof styles, such as asphalt, you can safely install a new layer of shingles over an existing layer, but there is a limit. Professionals often recommend that you have no more than two layers of shingles on your roof, but in some instances, even two layers is a problem. The issue is that when you install new shingles over existing shingles, the new shingles will eventually take on the same form as the old shingles.

So, if the old shingles were uneven or had dips and dumps, the new shingles will subsequently take on these deformities. While it might seem like an investment, the best long-term solution may be to strip the roof and start with a fresh surface. Multiple shingle layers may also require a permit in some locations, so if you have more than two layers, you might also be in violation of local codes. 

2. Installation Concerns

As a homeowner, you have a number of opportunities to complete projects on your own. However, just because you have the option does not mean that you should always take advantage of it. Unless you have experience in the field, homeowners should avoid performing roof installation and repairs on their own.

In terms of issues with the shingles not resting flat, incorrect spacing during the shingle installation process can typically lead to this problem. While it might not be noticeable at first, as the shingles settle, the problem will begin to surface. More important, the installation pattern for the shingles may vary depending on the area on the roof, which is another factor most homeowners simply aren't aware of. 

Whether you know why you're having issues with your shingles not resting flat or you don't, it is essential that you have your roof inspected by a professional. If you ignore the problem, you could face costly repairs. A company like The Roof Doctor will look over the roof, highlight the problem, and help you with the repairs you need.
