Hail Claim on a Nine-Year-Old Roof With Ridge-Cap Fastener Damage
Nine years after installation, a 28-square architectural shingle roof shows granule loss on the south slope, several circular depressions in the field, and a 3-foot section of exposed black mat along the ridge. The homeowner filed a hail claim after a storm that produced 1-inch hail and claims all slopes must be replaced. The insurance adjuster asks you to inspect. The south slope faces the prevailing storm direction. The gutters contain moderate granules. The ridge cap is nailed with four nails per cap, and several nail heads are visible through the cap. Adjacent metal roof vents show no dents. The attic decking is 7/16-inch OSB with no visible cracks. The homeowner wants a letter saying the entire roof is hail-damaged.
1. How do you distinguish hail damage from blistering, mechanical damage, and normal weathering on this roof?
Read the worked answer
Hail damage is random and fresh. It typically shows as circular or irregular impacts with displaced granules, a bruised or soft spot in the mat, and sometimes a fractured mat. Collateral evidence matters: dents on metal vents, gutters, downspouts, and flashing, and granules washed into gutters. The absence of dents on adjacent metal vents weakens the claim that this slope took a damaging hail strike.
Blistering is usually circular, raised, and popped, often in a pattern that follows roof temperature or ventilation problems, and it lacks fresh granule displacement. Mechanical damage is linear or concentrated where someone walked, dragged equipment, or dropped tools. Normal weathering shows uniform granule loss, slight curling, and surface erosion, especially on the south slope. The exposed mat at the ridge with visible nail heads points to a fastener or installation defect, not hail. Each condition should be documented separately; do not lump all of them into one hail conclusion.
2. What inspection protocol would you use, and what would you record?
Read the worked answer
Inspect all roof slopes, not just the south slope. Lay out at least one 10-foot by 10-foot test square on each slope and count and mark hail hits by type: granule displacement, bruise, and mat fracture. Photograph the test squares with a scale, then photograph the ridge, valleys, hips, vents, gutters, and downspouts. Probe suspect impacts gently to determine whether the mat is soft or fractured, but do not create damage.
Check the attic for cracked or fractured decking and for evidence of long-term leakage. Compare the south slope with the north slope and with any shaded areas. Record the ridge-cap nailing, visible nail heads, and the exposed mat as separate defects. Note the date of the storm, the hail size reported, and the absence or presence of collateral metal damage. Your report should distinguish functional damage from cosmetic granule loss and should state the basis for repair versus replacement.
3. The homeowner insists on a letter saying the entire roof is hail-damaged. How do you respond?
Read the worked answer
Explain that your report must describe what you actually observed, not what the claim needs. A blanket statement that the entire roof is hail-damaged would be unsupported if the test squares, collateral evidence, and slope comparisons do not show it. That kind of letter can damage your credibility and may create problems for the homeowner with the insurer.
Offer a factual report: the hail indicators you found, the areas that are not hail-related, the ridge-cap defect, and the repair options. If the functional damage is limited to one slope, say so and explain why partial replacement may be appropriate; if the damage is widespread enough to justify replacement, document the test-square counts and collateral evidence. Let the adjuster and homeowner make the coverage decision from the evidence. Put your findings, photos, and limitations in writing and keep a copy.
