Did you just have your old roof removed and the new one looks wavy? There are two goals that a new shingle roof is intended to achieve. First is to improve your home’s aesthetics and curb appeal. The second goal is to create a protective seal between your home and the elements. If your shingles are curling, bumpy, wavy, or lumpy, this can potentially be a problem. However, you don’t have to start panicking just yet.
If your roof shingles are not lying flat, there can be several possible reasons. These would include your roof’s age, the temperature and weather conditions, and the overall roof condition. In some instances, the shingles will seemingly fix themselves, almost like magic. Other times, it will require costly repairs to correct the issue. Here are some common causes:
Causes of a Wavy Roof
1. Shingles Not Sealing – Most asphalt shingles have an adhesive strip. When heated by the sun, the strip will cause the shingles to lay down and bond together. It is not uncommon for a new roof to look a bit wavy until this permanent seal is created. This is normally not a problem unless you experience windy conditions that can catch the shingles. Applying a temporary adhesive will do the trick.
2. Multilayer Roofs – It is always better to tear off your old roof and install a new one. However, some areas allow multilayer roofs, which can save homeowners the cost of a tear off and debris removal. However, the new shingles will keep to the form of the old layer. So, if the old roof had a bumpy or lumpy appearance, the new layer will as well.
3. Poor Installation – If you continue to see a problem after the roof has had a sufficient time to seal, it is possible that the cause is a poor installation. Incorrectly placed and nailed shingles can cause them to be uneven. The best way to avoid this issue is to hire a reputable and trustworthy Shingle Roof Specialist. Always take the time to investigate a company, ask for references, and check out online reviews.
4. Defective Shingles – There is always the possibility that the cause of a wavy roof is the result of a manufacturer defect. Purchase only high-quality roof shingles from a good source. Cheap shingles are often thin and easily torn, and they don’t often adhere to rigorous quality controls and inspections. Moreover, if the shingles are warped, they can sometimes seal unevenly.
Today’s blog article answers the question, “Why does my roof look wavy?” If your new roof was installed in the winter, wait until outdoor temperatures get warmer and the shingles have the opportunity to seal. Nevertheless, if you suspect the problem was caused by either poor installation or defective shingles, contact a roofing contractor. The shingle manufacturer should stand behind their warranty, unless the issue was caused by the roofer did not follow their installation instructions.
