Have a wavy roof and trying to figure out why or looking for a fix?  A roof with a wavy look to it can be caused by a number of reasons, but the problem may be short lived.  Let’s take a look at some of the typical causes of a wavy shingles, especially after a new roof is installed.

Causes of a wavy roof:

  • The felt paper used on the decking was potentially wet or bubbly when laid down.  Thankfully this is something that can be fixed with just a little time and heat.  Typically after a few warm summer weeks, the shingles will lay flat and you will no longer notice the wavy look.
  • First layer of shingles were wavy and the roofer laid directly over the existing layer.  This is a bad move, a roofing company should not lay new roofing shingles over shingles that are wavy.  A new roof will be required, after stripping both layers of shingles, to achieve a quality flat look.
  • Damaged decking could also cause a wavy look to shingles.  Inspect the plywood from the attic and look for cracks, sagging, or rotting.  If any of this is found, be sure to have a roofer replace any plywood, with the required thickness of board that is code for where you live.
  • Quality of the roofing work in general can also cause a roof to look wavy.  Potentially it could be caused if the shingles were not properly aligned or not nailed fully.  Ultimately there is no single answer for why a roof may look wavy, but could be a combination of factors.
