Hail Damage Repair

Round bruises with granule displacement. The classic hailstrike on asphalt: a circular impact zone where granules have been displaced, exposing the dark asphalt mat underneath. Diameter ranges from dime-size (3/4") for marginal damage to golf-ball-size (1.7") for severe damage.

Mat fracture without granule loss. Marginal hail can crack the asphalt mat beneath the granule layer without dislodging granules. Looks fine to the naked eye; shows up under thumbnail probe as a soft, springy spot. ASCE/HAAG hail-assessment methodology calls these 'functional damage' and they shorten shingle life dramatically.

Soft-metal verification points. Hail strikes on the rounded surfaces of roof vents, gutter aprons, downspouts, AC condenser fins, and aluminum-clad fascia leave clear dents. These soft-metal hits are the highest-confidence indicator of a genuine hail event — and adjusters use them to verify the storm produced damaging hail.

Pattern direction matters. Real hail produces a directional damage pattern — predominantly on one side of the house (the side facing the storm's approach) with reduced damage on the leeward side. Pattern-less damage spread evenly across all slopes typically indicates blistering or mechanical wear, not hail.

Window screens and painted surfaces. Hail also dents window screens and chips paint on south- or west-facing trim. These secondary indicators corroborate the roof damage and matter for insurance documentation.

Test squares. We mark four 10×10 ft sample squares on each significantly-affected slope (one in each corner of the slope) and count visible hailstrikes per square. This is the HAAG-standard sampling method adjusters trained at HAAG Engineering recognize on sight.

Strike-density threshold. The HAAG threshold for functional damage is typically 8+ strikes per 10×10 square on the dominant slope. Carriers (NJM, State Farm, Allstate, Liberty Mutual, Travelers, Plymouth Rock) use this benchmark when scoping the claim — partial-slope replacement for marginal density, full-slope or full-roof for above-threshold density.

Photo grid with chalk circles. We circle each visible hailstrike with chalk before photographing the test square. The chalk circles make the strikes visible in photos that an adjuster reviewing the claim file remotely can count.

Soft-metal corroboration. We photograph every dented vent, gutter, downspout, and HVAC condenser fin. Dent diameter is documented (using a quarter or a coin as reference scale) — the diameter ties to hailstone size and corroborates the strike pattern on the shingles.

Consequential-damage map. Beyond shingles, we map damaged window screens, paint chips on trim, dented exterior light fixtures, and dented mailboxes. Comprehensive documentation supports the claim and prevents the adjuster from dismissing the roof damage as 'mechanical' wear.

Adjusters under-scope hail claims more often than wind. Standard insurance adjusters typically don't have HAAG certification; many under-count strikes per square, miss mat-fracture damage that requires thumbnail probe, and write partial-slope scopes when full-roof replacement is warranted.

Supplements get filed routinely. About 60% of hail claims we work require at least one supplement filing after the initial estimate. We document the missing items with photos, code references, and HAAG methodology — most NJ carriers approve when supported.

Code-upgrade items they miss. NJ Uniform Construction Code requires drip edge (R905.2.8.5), ice & water shield (R905.1.2), and proper ventilation on every reroof. Many adjusters write the membrane scope but skip the code items. Supplements catch these.

Matching-shingle issue. Some carriers cap matching at one slope; others approve full-roof when matching shingles aren't available. NJ has a Matching Statute (N.J.A.C. 11:2-42.9) that requires reasonable uniformity of appearance — a strong supplement argument when partial replacement leaves visible color mismatch.
