Todays home was built in 2004, the roof covering is three tab shingles.
There were 6 - 7 shingles that had a small spot about the size of a quarter where the granuals were missing leaving the asphalt exposed. You could even see some of the fiberglass.
I’m just curious if anyone has seen this and what causes it. The shingles are fairly new. I would think these shingles are succeptible to 'breaking down" pre-maturely in the hot Florida sun.
Thanks in advance for your feedback.
