Rippling Asphalt Shingles: Why Does It Happen?

An asphalt shingle roof that has a rippled surface detracts from your home’s curb appeal. Not only that, but it is also an indication of a problem that requires immediate attention. That’s not always the case, however. If your roof is fairly new, the shingles will normally look a little lumpy after installation. Within a couple of warm days, they should eventually lay flat.  

If your shingles look wavy for more than a few days, or if they are quite old, you likely have to contact your roofing contractor. Advanced Roofing Inc., one of the top local roof repair contractors, explains the common causes of wavy, rippled asphalt shingles. 

Installation Mistakes

To ensure the success of your roof replacement project, you need to hire a reputable roofing company. Doing so can help you minimize mistakes that can lead to issues later on. A qualified and experienced roofer knows that felt should always be stapled and shingles nailed down in the direction the shingles are being laid. Otherwise, they can be blown off due to strong winds and lead to the roof surface looking wavy or rippled.

Re-Roofing Issues

A re-roof involves installing new shingles directly over the old ones instead of removing the old shingles first. This often leads to moisture getting trapped under and within the old shingles, which may cause moisture damage to the underside of the new ones. As time passes, the new shingles absorb the moisture and begin rippling or curling. This can lead to the new roof’s early deterioration.

Roof Leakages

Residential roofing systems require maintenance to ensure their long-term weather performance. However, many homeowners fail to do so, disregarding potential issues like leaks. They form as moisture from precipitation or humidity penetrate the shingles, where they can build up on the underlayment for weeks or months before traveling through your roof decking and into your home. The water buildup can eventually warm the shingles surrounding the leak and cause the roof to look rippled or wavy. 

Poor Ventilation

A poorly ventilated attic causes moisture to condense on the underside of the decking boards. Over time, it can penetrate through the boards and affect the shingles. Your roof decking will eventually warp, and your shingles will ripple or buckle. You have to make sure your roof has adequate ventilation to prevent this from happening.
