Documenting Wind, Hail, and Ice-Dam Roof Damage for the Claims Process
A commercial roof claim around Ann Arbor usually starts with one of three things: a wind event that lifted membrane or metal edge, an ice dam that backed water under flashing over a Michigan winter, or hail damage that's obvious on a metal roof and nearly invisible on a single-ply membrane until someone knows where to look. We document what we find factually and thoroughly, because the strength of a claim comes down to the quality of the evidence, not how the story gets told.
Wind Damage: Where It Actually Starts
Wind damage on a flat or low-slope commercial roof almost never starts in the field of the membrane. It starts at the perimeter , edge metal, coping, and parapet flashing , where uplift pressure concentrates hardest. We inspect those zones first, because a membrane that looks intact from the ground can have edge metal that's already lifted and working loose, which is the failure point that turns a minor wind event into a full membrane blow-off during the next storm. We photograph and measure lifted or displaced edge metal, document fastener pull-out patterns, and note wind speed and direction data from the event date to tie the damage to a specific, documentable cause.
On standing seam and R-panel metal roofs, wind damage shows up as panel oil-canning, clip failure, or seam separation, and we document each of those distinctly because an adjuster evaluating a metal roof claim is looking for different failure signatures than on a membrane roof.
Hail: The Damage That's Hardest to See From the Ground
Hail damage on a single-ply membrane rarely looks dramatic. It shows up as granule loss on modified bitumen cap sheet, bruising or fracturing on EPDM that's gone brittle with age, or dented pipe boots and rooftop equipment housings that took direct hits before the membrane itself did. We walk the field methodically, checking rooftop equipment and penetration flashing for impact marks even when the membrane field looks clean, because those impact marks on ancillary equipment are often the clearest evidence a hail event actually occurred at that address on that date.
Ice Dams and Freeze-Thaw Water Intrusion
Freeze-thaw cycling drives a specific kind of Michigan roof damage: meltwater backing up behind an ice dam at a parapet wall or scupper, then working under flashing that was never designed to hold standing water. This kind of damage often gets discovered well after the freeze event that caused it, once interior staining shows up during a spring thaw. We document the interior damage pattern alongside the exterior roof condition and correlate it to the weather record from the likely event window, because a delayed-discovery claim needs that timeline connection more than a same-day wind claim does.
Documentation Support We Provide
- Dated, timestamped photo documentation of every damage point, keyed to a roof plan
- Measurements of lifted edge metal, fastener spacing, and membrane displacement
- Weather event data correlated to the inspection date and damage pattern
- A written scope of repair or replacement tied directly to the documented damage, not a generic estimate
- Emergency tarp and dry-in to stop ongoing water intrusion while the claim is under review
- Photos and notes organized in a format adjusters can move through quickly
What We Don't Promise
We don't promise a claim outcome, and we'd tell any owner who asks that we can't. What we control is the quality and completeness of the documentation we hand over, and thorough, factual documentation is what gives a claim its best chance with an adjuster. We describe damage as we find it and let the evidence make the case.
Emergency Response Before the Claim Is Even Filed
A lot of storm-damage calls come in as an active leak, not a claim question. We tarp and dry-in the affected area first to stop water intrusion from getting worse, then move into full documentation once the building is stabilized. That order matters , a building owner shouldn't have to choose between stopping a leak and preserving evidence for a claim, and getting the tarp up fast doesn't compromise the documentation of what caused the damage.
Questions Owners and Property Managers Ask During a Claim
How fast can you get someone out after a storm?
We prioritize emergency tarp and dry-in calls after a storm event and move into full documentation as soon as the immediate water intrusion risk is under control.
Will your documentation hold up with our adjuster?
We document damage with dated photos, measurements, and weather correlation formatted the way adjusters expect to review it. We can't speak for how any individual adjuster rules, but we build the file to be as complete and factual as possible.
Can you tell the difference between storm damage and normal wear?
Yes, and we'll say so plainly if what we find looks like age-related deterioration rather than event-driven damage, because that distinction matters for how the claim gets evaluated.
Do you work directly with our public adjuster or insurance-side estimator?
We're glad to walk the roof with whoever is evaluating the claim and answer technical questions about the assembly and the damage we documented.
What if the damage is worse than it looked from the ground?
That's common, especially with hail on a membrane roof or ice-dam damage discovered during a spring thaw. We document what we actually find on the roof, even if it exceeds what prompted the initial call.
