How Hail Damage Repair Works, Step by Step
Hail damage is rarely obvious from the driveway. Someone has to get on the roof deck, walk the slope, and read the surface before anyone can price the work honestly. Here is the order we follow.
- Rapid damage inspection comes first, so we chalk every bruised shingle, dented vent boot, and chipped ridge cap before the next storm rolls in.
- Emergency tarping covers the interior that same day, because water seeping past a cracked mat will wick into the sheathing and start rot.
- Insurance claim assistance follows, with a line-item estimate, Xactimate documentation, and adjuster coordination up on the roof.
- Tear-off exposes the substrate, and we install replacement decking wherever plywood or OSB has buckled, swelled, or lost fastener grip.
- Rebuild lays synthetic underlayment and ice-and-water shield along the eave and valley, then sets replacement shingles with a nail gun.
- The closing roof inspection checks the ridge vent, soffit vent, and attic fan, since crushed ventilation traps heat and cooks the insulation.
Materials We Choose After a Hail Event
Replacement shingles matter more after hail than after ordinary end-of-life wear. A bruised mat sheds granules quickly and leaves raw asphalt facing the sun. We match the existing profile when we can and explain the tradeoffs when we cannot.
- Architectural shingles are laminated, dimensional, and heavier than a three-tab shingle, so they absorb small impacts across the field course.
- Asphalt shingles from GAF or Owens Corning carry warranties most carriers treat as insurance-approved material.
- Synthetic underlayment replaces roofing felt and tar paper, which tear fast once hail drives an edge through the surface.
- Ice-and-water shield is self-adhered, sealing around nails and fasteners at the eave where ice dam water backs uphill under the courses.
- Copper and aluminum flashing outlast steel at chimney flashing and counter-flashing, the two details hail dents open first.
- Modified bitumen, EPDM, and TPO membrane cover flat sections where a built-up roof with a coating handles ponding better than shingles.
- Composite, clay tile, and concrete tile shrug off most hail yet crack under a dropped tool, so we walk those roofs on battens.
- Wood shake and cedar shake shed hail well, but repeated hits split the grain and speed the decay without a maintenance coating.
- Slate and standing-seam panel roofs hold up, though a corrugated panel or soft aluminum canopy shows every strike on the roofline.
What We Inspect, and What Failure Looks Like
A roofer reads the failure, not just the dent. Hail lands hardest on high points, so we start at the ridge, hip, and verge lines, then follow the water downhill to see where it is going.
- Granule loss across the field course and valley that leaves the bitumen exposed and turns the rooftop gray.
- Blistered, buckled, or algae-stained shingles that read as age but hide impact damage underneath.
- Soft mats that flex under a boot, the hail signature photographs alone tend to miss.
- Dented ridge cap, drip edge, and any pipe flashing or pipe boot sitting on the roof plane.
- Cracked sealant and mastic at step flashing, apron flashing, and boot flashing, where water seeps in.
- Rot in the fascia, soffit, or overhang when a clogged gutter and downspout push water back under the eave.
- Sagging rafters and trusses, or a softened ridge beam that tells us the leak has run for months.
- Cracked skylight curbs, dormer cheeks, and parapet coping on commercial and mansard or gambrel rooflines.
Local Conditions, Timelines, and What Drives Cost
Spring thunderstorms drop hail in narrow bands, so one street gets pounded while the next block is untouched. That is why we inspect rather than assume, and why two neighbors can get very different scopes.
Hot, dry summers harden shingles until they crack instead of flexing. Fog and morning dew then keep the surface damp long enough for a small tear to widen before the winter rains arrive.
- Most shingle repairs take one day, while a full tear-off on a standard ranch home runs two to three days in dry weather.
- Steep pitch, three-story access, and fragile tile add labor, because tile work needs a scaffold and a roofing square for layout.
- Decking replacement raises the roof estimate, since every sheet of plywood or OSB under the underlayment adds material and disposal.
- A dumpster, debris hauling, and building code rules on ice-and-water shield coverage are fixed line items you should see in writing.
- Insurance typically covers the storm-damaged slope, while your deductible and any upgrade to a coated product stay with you.
