Why Is My Asphalt Shingle Roof Rippling?

Asphalt shingles can last for several years and withstand extreme weather conditions if properly installed. They sometimes develop a wavy appearance after installation, but this should disappear after a few days. If your shingles still look uneven after several weeks or rippling starts after some years, it could be due to the following reasons.  

Why Is My Asphalt Shingle Roof Rippling?

Improper Roofing Techniques

Some roofers perform re-roofing, which involves installing new shingles over old roofing material. Unfortunately, this method causes the moisture trapped within the old shingles to seep into the underside of your new shingles. Over time, the new shingles will absorb the moisture, causing a rippled appearance. 

Poor Roof Ventilation

Good attic ventilation ensures moisture can escape through the vents, preventing condensation from building up underneath the roof decking. Inadequate ventilation will cause moisture to accumulate inside the attic, which then leads to the warping of the decking material and the rippling of asphalt shingles.

Wind Damage

High winds can cause asphalt shingles to have a rippled or warped appearance. If the damage is moderate, rippled shingles can still be smoothed and repaired. However, if the shingles developed creases or cracks, it’s best to replace them instead.

Roof Leaks

Leaks can pool on the underlayment after a heavy rain. As a result, the shingles also get soaked in moisture, causing them to develop a rippled appearance.

Manufacturer Defects

Sometimes, shingle rippling is caused by bad roofing products. If your roof is still under warranty, contact your contractors immediately so that they can address the problem. Make sure to review your roofing warranty so you know what is covered.

No hassles, no stress roofing contractor.

We've worked with a number of contractors over the years doing home improvement projects and I can say that, without question, working with Pressure Point was about as easy as it gets.

Everything about the project, from sales all the way to final inspection, went like clockwork and without a hitch.  They delivered more than they promised, on time and within budget.   We could not have been happier with their personnel, products and services.  Highly recommended!

I've changed my review from a 1 star to a 4 stars. Matt Stone got right on a pretty poor job done installing a skylight. He had his guys remove the skylight, move it, repair the roof and inside ceiling to its original state, paint it, repair some external trim that was damaged, and all within a few days after talking to him about the multiple problems. It was really an eyesore from the inside. I'd give a 5 star if this had been done well the first time. The skylight just didn't fit the space I first wanted it and was told it would. More communication about the potential problems might have allowed this to be done right the first time. But, Pressure Point Roofing gets 5 starts for making amends and correcting a pretty ugly problem, very fast! Thank you.

I needed someone to come out to take a look at a leaky roof. I contacted Pressure Point Roofing, Inc. and they came out the same day. They gave me a quote to fix the problem and I agreed to their terms. It was about 4PM and I knew they closed at 5PM but they stayed and fixed the leak at no additional cost. I was very happy and impressed. Would recommend them to anyone. Thank you Pressure Point Roofing for earning our families trust. Will definitely be doing business with you again.

I am so happy I chose Pressure Point to replace my 40-year-old roof.  The crew was professional, efficient, and answered all my questions, addressed the few concerns I raised, and made me feel comfortable, trusting them with such a big project.  I couldn't be happier with their work and the look of my new roof.
