If you’ve noticed gritty, black or colored particles in your gutters, you’re likely seeing roof granules from your shingles.
These mineral or ceramic granules protect shingles against UV rays, add fire resistance, and help your roof shed water.
While some granule loss is normal as your roof ages, sudden increases may signal storm damage, accelerated wear, or even a sign of a recently installed roof settling in.
Excessive granule buildup can shorten your roof’s life, clog gutters, cause water backups, and leave shingles vulnerable to leaks and UV damage.
For Houston area residents, frequent granule loss or finding bare patches on shingles means your roof may need professional attention.
Seeking a roof inspection from a trusted local expert ensures you catch issues before they turn into costly repairs or leaks.
