We can't blame you if you're puzzled that your new roofs are wavy or rippled. It's an odd sight to see your sloped roof material have different shadows casted and look different on the ground. Wavy or rippled roofs are a natural occurrence, but these might indicate defects in some cases. To make sure your roof is operating properly, here are a few things to know about them.
The Primary Causes of Wavy or Rippled Roofs
Wavy or rippled roofs occur due to these two usual causes.
Recent Roof Replacement
New asphalt shingles are still at full or reduced length depending on the temperature during their installation. Your professional roofers gave them allowances to expand or contract. If they improperly spaced the materials, you can see the wavy or rippled appearance as they expand during summer and contract during winter.
Poor Attic Ventilation
Asphalt shingle materials tend to expand faster when they absorb high heat levels. High-quality asphalt shingle manufacturers continuously test their materials for regulatory compliance, ensuring they won't be wavy or rippled a few weeks or months after installation. Your roofer's investigation may reveal that your asphalt shingles are wavy because of poor attic ventilation, encouraging it to absorb more heat than necessary
AABCO Roofing has an excellent post detailing how you can prevent massive roof repairs in an excerpt below.
“Wavy” or warped roofs don’t happen naturally. There are a few reasons why it occurs, but please remember that it is dangerous for you to attempt to DIY or self-inspect your roof. Rather rely on a local roofing contractor for professional help.
Laying The Foundation
A foundation is not just limited to the bottom of your home. Your roof needs one too.
The foundation of a roof is made up of the frame for the roof as well as the decking. If your roof’s foundation is compromised in any way, you will end up with a warped roof. If your decking or frame is damaged in any way, it can be hazardous for you and your family. If your attic is safe to enter, things you can look out for include cracks or rotting wood. If you’d rather not take the risk, don’t hesitate to call in a professional to do the inspection.

In some instances, you could also end up with a water leak in the roof which does compromise the structure and integrity of your roof. You will need a professional roofing contractor to do a thorough inspection and advise you if you should repair or replace your roof.
Underlying Problems
Your roof will have a layer of product that separates your tiles or shingles from your decking, this is known as the underlayment.
Depending on the type of roofing tile you have on your roof, different materials can be used as the underlayer. If your underlayment layer is not placed correctly, your roof can become compromised. In some cases, this can happen after a new roof installation.
It’s A Little Too Hot In Here
Just like every commercial building needs to have good ventilation, so does your household roof.
Without good ventilation in your roof, you will end up with excess moisture trapped in the attic. This will lead to your wood decking to possibly warp as the underlayment will end up becoming distorted. (Continue reading here to learn more)
