How much granule loss is too much?
It all depends on how much loose granules you find, and how old your roof is. If it’s over 25, it’s probably time to replace your roof. If it’s under that age by a decent factor, then you may just be experiencing some shingles giving out that have been unlucky enough to be worn out faster.
What does it mean when a roof has granular loss?

What is delamination of shingles?
Delamination can occur over time due to your roof’s exposure to UV rays or from improper installation of the original roof. If moisture gets between the membrane of the roof and the shingles, this can also cause delamination. This delamination can cause both water and wind damage to the existing roof.
