Hail is not the Valley's most frequent roof peril — monsoon wind events happen far more often — but Phoenix does see hail-producing storm cells most years, and when one tracks across a commercial corridor it can affect dozens of low-slope roofs in the same afternoon. Commercial hail claims get scrutinized closely because the damage on a low-slope membrane roof isn't as visually obvious as it is on a sloped shingle roof, and because Phoenix's intense UV exposure already puts wear on membranes that can be mistaken for, or mistaken as evidence against, hail impact.
We document hail damage on commercial roofs as the roofing contractor handling the assessment — producing the inspection findings that support the claim, not filing or negotiating the claim itself.
Finding Hail Impact on a Low-Slope Membrane
On TPO and PVC membranes, hail impact leaves circular depressions where the stone compressed the membrane and the insulation underneath — impressions that are often difficult to see without close-range inspection in low-angle light on a dry surface. We walk the full roof in a grid pattern and photograph impact density by section, rather than spot-checking a few areas, because impact density is what an adjuster uses to judge whether the roof needs section repair, full recover, or replacement. On EPDM, impact often shows as surface bruising rather than a clean depression, and on gravel-surfaced built-up roofing, impact assessment requires clearing sample areas of aggregate to inspect the cap sheet beneath.
Distinguishing Impact From UV Wear
This is the step that gets a Phoenix hail claim challenged if it's skipped. A membrane that's been on a roof for twelve summers already shows chalking, minor surface cracking, and reduced flexibility from UV and thermal cycling — none of which is impact damage, and none of which a carrier will pay to correct as storm loss. We document impact geometry (circular depression pattern, consistent spacing, granule or coating displacement at the point of impact) separately from general membrane condition, so the report doesn't conflate storm damage with the roof's baseline age and wear.
Reporting Impact Density and Scope
The written assessment includes an impact density count by roof section, photography keyed to a roof plan, membrane type and approximate install age, and our judgment on whether the documented impact pattern is consistent with section repair or points toward a full recover or replacement. Where the roof includes rooftop equipment — curbs, condensing units, conduit — we note hail-related damage to those components too, since equipment damage is frequently part of the same claim. If your insurer schedules a joint inspection, we're available to walk the roof with the adjuster and point to the impact findings directly.
We're your roofing contractor, not a public adjuster — we inspect, document, and produce the damage assessment so you and your adjuster are working from an accurate, complete scope.
Frequently asked questions
How can you tell hail damage from normal wear on a Phoenix commercial roof?
Hail impact leaves a consistent, roughly circular depression pattern at the point of contact, distinct from the general chalking, surface cracking, and stiffening that Phoenix sun produces over a membrane's service life. We document impact geometry separately from baseline UV wear so the two aren't conflated in the report.
Is hail actually common enough in Phoenix to cause commercial roof claims?
It's less frequent than monsoon wind damage, but Phoenix does get hail-producing storm cells in most years, and a single event can affect many roofs across a corridor at once. When it happens, low-slope commercial membranes need a closer inspection than a shingle roof to identify the impact.
What size hail causes damage to a TPO or PVC commercial roof?
Impact impressions typically become identifiable at around 1 inch in diameter and larger, though membrane condition, thickness, and substrate affect susceptibility. We assess and document what we actually find on your roof rather than relying on a general size threshold.
Do you provide a hail impact report I can give to my insurance adjuster?
Yes. We produce a written assessment with impact density by roof section, photography keyed to a roof plan, and membrane condition notes, formatted for the adjuster reviewing the claim. We're available to walk the roof with the adjuster if a joint inspection is scheduled.
Can hail damage be repaired, or does it always mean full roof replacement?
It depends on impact density and the membrane's remaining service life. Isolated impact on a newer membrane often supports a section repair. Dense impact across an older membrane closer to the end of its service life more often supports recover or replacement. That judgment is based on the documented condition, not a fixed rule.
