Compare the timing and roof condition. Loose granules after installation and persistent loss with visible damage require different evaluation.
Some loose granules after a new shingle installation can be normal. Persistent loss accompanied by a changing roof surface or other damage deserves review. The amount in one gutter photograph alone cannot establish the cause.
Why the installation date matters
GAF's granule-loss bulletin explains that excess manufacturing granules can shed initially and diminish over time. It recommends contacting the manufacturer when significant loss persists after the initial period or the shingles show appearance changes or other damage. Follow the guidance for your actual product.
That distinction does not mean every new roof concern should be ignored. If you see a bare area, an unusual pattern, or a sudden change, send the installer photographs and request an assessment. Avoid washing or brushing the roof to make the comparison easier; that could alter the condition being evaluated.
Keep a simple observation record
- Installation date and exact product, if known.
- Dates of observations and any storm or nearby work.
- Wide roof photographs taken from a safe location.
- Photographs of affected areas obtained by the inspector.
- The installer or manufacturer's response and next review date.
For example, a record showing a stable roof appearance and decreasing loose material is different from one showing a progressively exposed patch. Neither should be reduced to “there are granules in the gutter.” Ask the inspector to describe the surface condition as well as the collected material.
Keep cleaning records so later observations have context. For an older roof or additional symptoms, review roof inspection warning signs and arrange a condition assessment.
Common questions
Frequently asked
