Observed a roof this morning where most of the shingles had cracking through out. The roof is only 5-7 years and there are 2 layers.
Is this a defect in the shingle? What causes this cracking? It is hard to see in the pictures all the small cracks iat the shingles.
I recommend having a roofer evaluate.
They also did a lousy job of attaching the patio cover.
