What We Check During A Granule Loss Assessment
We review missing tabs, lifted shingles, fasteners, seal strips, granule loss, ridge areas, roof edges, surrounding wear, and whether the repair is isolated or part of a larger aging pattern.
Granule loss patterns are diagnostic. Hail damage produces circular impact craters with granules knocked off in a spatter pattern — each impact leaves a dark spot. UV degradation produces more uniform granule loss across south-facing slopes that get the most sun exposure. Mechanical abrasion from overhanging branches produces loss in a line. We photograph and document the pattern before giving you a recommendation, which is useful whether you are planning repairs or preparing an insurance claim.
