First, assess the damage safely (from the ground)
The safest first step after hail is a ground-level inspection. Do not climb onto the roof until you know what you're dealing with. Wet shingles, cracked decking, and debris-covered slopes are a bad combination, and a roof that took a serious hit can have soft decking that doesn't feel wrong until you step on it.
Before you touch anything, take photos of every damaged area you can see. Photographing damage before any cover-up is part of the mitigation process itself, and pictures taken before the tarp goes on make your insurance claim faster and cleaner. Once the tarp is up, the adjuster can't see what's underneath it.
Wait until the storm has fully passed and the roof has dried before any inspection from above. If the damage looks significant or you're just not sure, get a professional roof inspection before anyone sets foot up there.
- Missing or lifted shingles: gaps or curled edges you can spot from the yard
- Dent patterns: hail leaves circular bruises on shingles, gutters, and flashing; check the gutters and downspouts first since dents show up clearly on metal
- Granule loss: a pile of dark grit in the gutters or at the downspouts means the protective surface took a beating
- Active leaks: check the attic for stains, drips, or wet insulation right after the storm passes
- Damaged skylights and vents: cracked skylights and dented vent caps are favorite hail targets
How do you tarp a roof so it actually holds?
A properly installed tarp is the most reliable short-term fix a homeowner can put up. A heavy-duty poly tarp secured with wooden battens can hold for months depending on the weather and how well it went on, and that gives you a real window to schedule permanent repairs without panic.
Gather everything before you climb: one or more heavy-duty poly tarps (thicker is better), 2x4 battens cut to tarp width, roofing nails or screws, a hammer or drill, a utility knife, non-slip footwear, and a safety harness if you have one. Size the tarp generously; one that barely covers the damage will leak at its edges. You want coverage extending at least three feet past the damaged area on every side, and over the ridge line if you can manage it.
The installation, step by step: clear loose debris and standing water from the damaged section. Lay the tarp so it runs from the ridge down toward the eave, covering the damage plus that three-foot margin. Fold the top edge over a 2x4 and fasten the batten to the roof just below the ridge, which anchors the tarp and sheds water away from the peak. Batten down both side edges so wind can't get under it. Then fold the bottom edge over another batten and fasten it at the eave, letting the tarp hang slightly over the gutter so water runs clear of the fascia.
Last check: make sure the tarp lies flat with no low spots. A tarp that pools water gets brutally heavy when saturated, and that weight can collapse decking that's already weakened. Flat and taut is the goal. When it's done, photograph the finished installation from a few angles; insurers expect documentation of your mitigation work, and photos plus receipts support reimbursement.
What if a tarp isn't the right tool?
Tarping isn't the answer for every situation. Small punctures, cracked flashing, or minor damage in awkward spots call for different patches. Just keep the key limitation in mind: all of these are a bandage, not a cure. None of them replaces a proper shingle repair or flashing replacement, and if the damaged area is bigger than a few square feet, a full tarp beats spot-patching every time.
And a repeat of the safety point, because it matters: don't climb onto a heavily damaged roof to apply sealant unless you have fall protection. This is exactly the kind of job our roof repair crew handles every week.
- Roofing cement: a thick asphalt-based compound for sealing lifted shingles, cracked flashing, and small punctures; bonds well to dry surfaces but softens in prolonged heat
- Roof sealant or caulk: good around vents, skylights, and flashing seams; useless on large open areas
- Self-adhesive roofing tape: seals seams and small tears quickly and holds for a few weeks
- Patch kits: pre-cut adhesive patches that work on flat or low-slope roofs, less so on steep pitches where water moves fast
- Plastic sheeting: a lighter stand-in for a tarp on very small areas; secure it with battens the same way
Documenting everything for the insurance claim
Good documentation is what separates a smooth claim from a frustrating one. Insurers cover emergency protective measures like tarping, but they expect you to show your work. The full storm damage and insurance guide covers the claim process in detail; here's the short checklist.
Photograph everything before repairs: wide shots of the whole roof, close-ups of each damaged spot, plus the gutters, downspouts, siding, and any interior water damage. Photograph the tarp installation, battens and all. Save every receipt for tarps, lumber, cement, and any labor you paid for; those are typically reimbursable. Write down when the storm hit, when you inspected, and when the temporary protection went up.
Then get a written estimate from a licensed contractor, because a professional assessment carries more weight with adjusters than homeowner photos alone. And report the damage to your insurer promptly; delayed reporting complicates claims. Read your policy before the adjuster visits so you walk into that conversation knowing what's covered.
The mistakes that turn a small repair into a big one
Most post-hail mistakes come down to three things: unsafe behavior, flimsy materials, or waiting too long. The single most expensive one is waiting. A small leak becomes a mold problem; a mold problem becomes a structural repair. The EPA, CDC, and FEMA all recommend drying wet building materials within a day or two to head off mold, so act fast even if all you do is get a tarp up.
One more thing, said plainly: watch out for door-to-door contractors after a hail event. Storm chasers are a well-documented scam. Some collect payment and disappear; others do work that voids your warranty. Hire local, and check the Oregon CCB license database before signing anything.
- Climbing a wet or damaged roof without protection: wait for a dry surface, use a harness, and leave steep or badly damaged roofs to the pros
- Waiting more than a day or two: mold adds thousands to a repair bill and can affect your family's health
- Using thin plastic or duct tape as your only protection: they fail fast in wind and rain; a heavy-duty tarp with battens is the minimum
- Tarping only the visible damage: a tarp that stops at the damage edge leaks around its perimeter; go three feet beyond on all sides
- Covering the damage before photographing it: pre-tarp photos protect your claim
