What Happens to Your Roof After Hail Hits
The storm passes, the sun comes out, and your roof looks... fine. That is the trap. Most hail damage is invisible from the ground, and it doesn't leak right away — it fails slowly, months or even a year later. Before you can understand the repair process, you need to know what hail actually does to an asphalt shingle roof:
- Granule loss. Hailstones knock the protective ceramic grit off the shingle surface, leaving bare, chalky, light-colored spots. Those granules are the shingle's armor against UV rays — once they're gone, the asphalt underneath degrades fast in Oklahoma sun. Check your gutters and downspouts: an unusual amount of granules collecting there after a storm is one of the first visible clues.
- Bruising. A direct hail strike crushes the asphalt mat beneath the surface without necessarily breaking the shingle. The result is a soft, dark, sometimes dimpled spot — like a bruise on an apple. You can often feel it with a gloved hand. Bruising weakens the shingle's structure and tells an adjuster exactly where hail impacted.
- Cracked and split shingles. Larger hail (quarter-size and up) can crack the shingle itself or split it along the impact point. Cracks open a path for water and are the fastest route from a hail claim to an interior leak.
- Collateral damage. Hail rarely stops at the roof. Dented gutters and downspouts, damaged ridge vents, cracked skylights, bruised AC condenser fins, and battered garage doors are all part of the same storm claim — and all things an adjuster looks for.
What an adjuster looks for is the same thing a trained inspector looks for: clusters of impact marks on the sun-facing slopes (where hail damage concentrates), bruising and granule loss on shingles, cracks and splits, damaged flashing and ridge caps, and collateral hits on gutters, vents, and skylights. Adjusters photograph and measure every mark because each one becomes a line item on the scope of work. If the damage isn't documented, it isn't in the estimate — which is why the first step in this process matters so much.
Want to know exactly what hail damage looks like before you call anyone? Our guide to hail damage on Tulsa roofs walks through the visual signs in detail. Then start here, at Step 1.
Step 1 Schedule a Free Roof Inspection
Do not wait for a leak. By the time water finds its way through hail-damaged shingles, the decking underneath is often rotting, and the damage is harder to prove to your insurer. Book an inspection within days of the storm — bruising and granule loss can take weeks to become visible, but a trained inspector can identify impact patterns immediately.
Proof Construction offers free post-storm inspections across the Tulsa metro. We document what we find with close-up photos, note the shingle condition, check flashing, ridge caps, gutters, and vents, and give you a plain-English report — no pressure, no obligation. This inspection is step one for a reason: everything downstream (the claim, the scope, the supplement) depends on what gets documented here.
Step 2 Document Everything
Before you file anything, build your evidence file:
- Photo and video of all sides of the house — roof surfaces from every accessible angle, gutters, vents, skylights, AC units, garage doors.
- Close-ups of every impact mark, bruise, and granule-loss spot you can find or that your inspector flagged.
- The storm date and any weather records (hail size, wind speed) for that day.
- Receipts for emergency tarping or mitigation if you had to protect the home.
One rule matters more than any other: do not tear off damaged shingles before the adjuster sees them. If the evidence is gone, the insurer can argue the damage can't be verified. Tarp it if it leaks, document it, and leave it in place.
Step 3 File Your Insurance Claim
Call your insurance company with your documentation ready. You'll need:
- The date of loss (the storm date) and a description of the visible damage.
- Your deductible and confirmation that you have replacement cost (RCV) coverage, so you know what to expect from the first check.
- A scheduled adjuster visit — and ask when they can come. After a major regional storm, adjuster availability backs up for weeks. That's the single biggest reason hail repairs take longer than anyone wants.
- Your right to have your own contractor present at the inspection. Insist on it. Your contractor represents you; the adjuster represents the insurer.
Step 4 Review the Scope of Work
A few weeks after the inspection, you'll receive the adjuster's estimate — the scope of work — along with your first check. That first check is usually the Actual Cash Value (ACV): replacement cost minus depreciation and your deductible. The remaining depreciation is released after the work is done.
Before you deposit anything, review the scope line by line:
- Does it include all damaged slopes, not just the ones visible from the street?
- Are gutters, vents, flashing, and skylights listed?
- Does it include code-required items — drip edge, starter shingles, ridge cap, ice-and-water shield in valleys?
- Do the roof measurements and pitch match reality?
Initial estimates frequently miss items. That's not a conspiracy — it's how the process works — and it leads directly to Step 5's ugly cousin, the supplement. If your scope looks short, don't cash the check and move on. Read our breakdown of how insurers build their estimates so you can spot what's missing.
Step 5 Select Materials
Once the scope is approved, you pick the shingle. The insurance settlement is based on like-kind materials, and in Oklahoma the standard is a quality architectural shingle — we're an Owens Corning Preferred Contractor (CIB #80004070), so we install Owens Corning systems with matching manufacturer warranties. Your contract should itemize:
- Shingle brand and line — never a vague "architectural shingles" line; you want the specific product.
- Underlayment — synthetic underlayment is standard on quality installs.
- Flashing, drip edge, pipe boots, and ridge vent — the details that keep a roof from leaking at its weak points.
- Ice-and-water shield in valleys and eaves, where Oklahoma freeze-thaw cycles do their worst.
Material lead times matter after big storms: shingle supply can tighten when every roofer in the state is buying at once, and that adds to the schedule. It's worth the wait for the right product.
Step 6 Tear-Off
The old roof comes off, usually in a day. A full tear-off to the deck is the standard for hail replacements — layering over damaged shingles hides problems and voids warranties. During tear-off the crew inspects the decking board by board:
- Rotted or water-damaged decking gets replaced — a common supplement item, because old decking that can't hold new fasteners isn't something the first adjuster visit can see.
- Code upgrades get installed: drip edge, updated flashing standards, and proper ventilation, typically covered under your ordinance-or-law coverage if your policy has it.
- The crew should protect your landscaping, use roof jacks and safety lines, and do a magnetic nail sweep at the end of every day — nails in your yard are the #1 customer complaint in roofing, and a professional crew never leaves them.
Step 7 Installation
New underlayment goes down, then the shingles — one to three days of active work for a typical Tulsa home. Quality installation is where the warranty lives: correct nailing patterns and nail placement (the manufacturer's spec, not "good enough"), proper starter rows, sealed and nailed ridge cap, and flashed transitions at chimneys, skylights, and walls. This is also when gutters get cleaned or replaced and downspouts get reattached, so the whole water-shedding system is done at once.
Weather cooperates or it doesn't — Oklahoma thunderstorms can stop a crew mid-job, which is another reason the calendar for hail repairs is measured in weeks. A reputable contractor keeps you informed and doesn't rush a roof just to hit an arbitrary date.
Step 8 Final Walkthrough
Before the crew leaves for good, walk the property with your project manager:
- Walk the yard — no nails, no debris, no shingle scraps.
- Check the roofline from the ground, and inspect flashing around chimneys, skylights, and vents.
- Confirm gutters are clean or replaced and downspouts are attached.
- Collect your paperwork — final invoice, manufacturer registration, and warranty documents. If the walkthrough isn't clean, speak up before the final invoice goes to the insurance company; it's much easier to fix then.
Once the work is complete, your contractor submits the final invoice, the insurance company releases the depreciation holdback, and the claim closes — usually within a couple of weeks of completion.
How Long Does This Actually Take? (Honestly: Weeks, Not Days)
After a major storm, the entire metro is filing claims at once. Adjusters are booked out, shingle supply tightens, and every reputable crew in the state is scheduling weeks ahead. Here is a realistic Tulsa timeline:
| Stage | Typical Timeline |
|---|---|
| Free inspection + documentation | Within 1–2 weeks of the storm |
| Claim filed, adjuster scheduled | 3–14 days (longer after major regional storms) |
| Adjuster inspection | 1–2 weeks after filing |
| Estimate / first check issued | 1–3 weeks after inspection |
| Supplement review (if needed) | Adds 1–3 weeks |
| Materials ordered and delivered | 1–2 weeks, weather and supply permitting |
| Tear-off + installation | 2–4 days of active work |
| Final payment / depreciation released | 1–2 weeks after completion |
Add it up: a clean claim runs 4 to 8 weeks from storm to finished roof; a claim with a supplement runs 6 to 10 weeks. Anyone promising a full hail replacement "by next week" after a metro-wide storm is either lying or cutting corners — or both. The fastest way through is exactly what this guide describes: inspect fast, document thoroughly, file promptly, and push the scope to be complete the first time. We mapped the full claim timeline in detail on our insurance claim timeline guide.
What Is a Supplement? (Spoiler: It's Normal)
A supplement is a formal request to the insurance company for additional payment — submitted with photos, measurements, and pricing — when the initial scope missed damage. And here's the thing to internalize: it is a completely normal part of the hail repair process. Insurance estimates are initial offers, not final verdicts.
The most common supplement items in Oklahoma hail claims:
- Missed slopes — hail damage on a back slope or a section the adjuster couldn't see from the ground.
- Collateral damage — gutters, ridge vents, skylights, or AC units written in after the fact.
- Decking replacement — rotted sheathing discovered at tear-off that no inspection could have seen.
- Code-required upgrades — drip edge, ventilation, and flashing standards under your ordinance-or-law coverage.
- Steep-slope and accessibility charges — legitimate labor line items that generic software estimates underprice.
A reputable contractor handles supplements for you at no upfront cost — it's part of getting the job funded properly, and it's why Step 1 (documentation) pays off twice. If your contractor tells you a supplement is "fighting the insurance company" and treats it as a battle, find a different contractor. It's paperwork, not warfare.
Protect Yourself: Get the Warranty in Writing
Oklahoma requires only a 1-year workmanship warranty on roof installations. That is the legal floor — and far too many storm-chaser crews treat it as the ceiling, if they honor it at all. Three ways to protect yourself before work starts:
- Workmanship warranty in writing, before you sign. Proof Construction gives every customer a 3-year workmanship warranty — three times the state minimum — in writing, covering the labor on your roof. If a contractor won't put the warranty on paper, that's your answer.
- An itemized contract. Materials by brand and line, underlayment, flashing, accessories, cleanup terms, and a nail sweep — all spelled out, all matching the approved insurance scope.
- No AOB pressure, no "free deductible." Never sign an assignment of benefits you haven't read, and never accept a contractor who offers to "pay your deductible" — that's insurance fraud in Oklahoma, and the homeowner is the one on the hook.
Local, licensed, insured, and willing to put everything in writing — that's the bar. Proof Construction has served Tulsa and Broken Arrow since 2015 as an Owens Corning Preferred Contractor (CIB #80004070), rated 4.9 stars from 127+ reviews, and our 3-year workmanship warranty comes with every roof, in writing.
Hail Damage Roof Repair FAQs
After a major storm, expect weeks, not days. Filing the claim, scheduling an adjuster, and reviewing the estimate typically takes 2 to 6 weeks before work starts, and the roof replacement itself takes 1 to 3 days of active work once materials arrive and weather cooperates. Simple, well-documented claims can close in 2 to 4 weeks; claims that need a supplement often run 6 to 10 weeks.
Three signs matter most: granule loss — bare, chalky spots where hail knocked the protective grit off the shingle; bruising — soft, dark, sometimes dimpled areas where the asphalt mat underneath was crushed; and cracked or split shingles at the impact point. Bruising and granule loss can take weeks to become visible, which is why a professional inspection after the storm matters.
A supplement is a formal request to your insurance company for additional payment when the initial scope misses damage. Yes, it is completely normal — insurance estimates are initial offers, not final verdicts. Supplements routinely add missed slopes, collateral damage, decking replacement, and code-required items. A reputable contractor submits them at no upfront cost to you.
Your contract should itemize materials (shingle brand and line), underlayment, flashing, and accessories; match the approved insurance scope; cover cleanup and nail sweeps; and include a workmanship warranty in writing. Oklahoma only requires a 1-year workmanship warranty — Proof Construction gives you 3 years, in writing, on every roof we install.
