A roof-condition signal

Granule loss: what it may mean

Granules can move for several reasons, so their presence in gutters or at downspouts needs context rather than an automatic conclusion.

A professional roof assessment is required to determine the appropriate next step for a specific roof.

Responsible roof decisions

Understand the condition before choosing the route.

Granules can move for several reasons, so their presence in gutters or at downspouts needs context rather than an automatic conclusion.

One visible symptom rarely tells the whole story. Installation, ventilation, exposure, product, storm history, previous repairs, and the condition of the entire roof can change the responsible route.

Useful observations

Document what changed, where it appears, and whether severe weather or roof work preceded it.

  • Location and concentration
  • Recent hail or wind reports
  • Bare-looking or inconsistent shingle areas
  • Changes in only one roof plane

Avoid a remote conclusion

Photographs support triage but cannot establish cause, concealed conditions, or treatment eligibility.

  • Inspect the whole pattern
  • Keep safety first
  • Route repair and storm concerns appropriately
