When you get a new roof for your home, you are completely entitled to expect it to be flawless. If your shingles do not look flat, there may be some kind of a defect involved, in terms of materials or installation.

There are several reasons why your new roof shingles may not be flat but rather wavy. The most common one is related to having a multi-layered roof. In this case, the new shingles layer will conform to the old layer; if the old layer has bumps and dips, so will the new layer.

Another common reason why your shingles do not look flat after getting a new roof has to do with the felt paper, which is placed before placing the shingles. If felt paper is exposed to humidity, it will form bubbles which may cause shingles to warp.

Installation mistakes can also cause your roof to look not as flat as it should. Sometimes, roofers fail to be precise, and a misplaced shingle will cause a domino effect.

Regardless the cause of the improper aspect of your roof, you should contact your expert Aurora roofing contractor and ask it to fix the problem.
