If you have had an asphalt roof installed within the last few years, then you may notice some issues with the shingles. While some problems indicate that the roof was installed improperly, others appear and are likely to resolve themselves. This is something that happens with buckling asphalt shingles. Keep reading to understand what the problem is, what it looks like, and how it can be fixed.
What Are Buckling Shingles?
Buckling shingles are asphalt shingles that have a large and elongated ripple down the middle of them. This ripple looks like a bump that sits horizontally across each shingle. Unlike other types of roofing problems, the buckling is likely to appear within the first few years after a roofing installation is completed. The buckles are typically the result of moisture.
Most commonly, the buckles are caused by the moisture present in the roof decking. The wood decking is exposed when the old roofing shingles are removed. The wood absorbs moisture from the air, especially if your roof installation is completed in the humid weather. The absorption causes the wood to swell. When the moisture is released, the wood shrinks and pulls on the shingles. This forces them to buckle.
Buckling is sometimes caused by moisture absorbed by the roofing felt. The felt or paper expands much like the decking, pushing the shingles upward.
Shingles can also absorb moisture themselves and buckle in the process. However, this is often seen once shingles have aged for some time.
How Are Buckling Shingle Repaired?
Buckling shingles do not necessarily need to be repaired, especially if they have just started to appear. Also, If your roofing installation has taken place within the last year or so, then it may be best to see if the problem resolves itself. While this is true, you can contact your roof installation professional. This is a good idea, especially if the roofing shingles are under warranty. The roofer can determine if the shingles are defective and if this is causing the problem. This is not likely, but mistakes during the shingle manufacturing process can contribute to early shingle failures. This can, in turn, cause the shingles to absorb water.
If your shingles do not flatten over time, then this may be a sign that water is not evaporating from the roof like it should. The culprit is likely trapped moisture in your attic. Moisture may have been able to escape through the holes or openings in your old roof, but the new roof may be much more sealed and airtight than your old one.
There are several different home issues that can lead to attic moisture. Leaks in the ductwork of your HVAC system and vented fans that force moist air into the attic are both common causes of high attic humidity. Also, if your basement is always wet, then humid and hot air may rise through the home and become trapped in the attic. Inspecting your home to find these sorts of issues and resolving them is a good way to fix shingle buckling problems.
If you do not see any obvious issues that may be causing attic humidity problems, then you may need to ventilate the attic properly. This can help to reduce the natural accumulation of moisture that is unable to escape. Ventilation can be acquired through the installation of a fan. You also may need to add undereave or soffit vents.
Whole house humidifiers are a good option to reduce the moisture in your house as well.
