Spring hail and summer derechos are rough on Chesterfield roofs, and most of the damage is invisible from the driveway. We climb up, document everything, and tell you straight whether it is worth filing a claim.

Hail is the most common and most misunderstood roof threat in Chesterfield. A spring storm can knock granules off shingles and fracture the mat underneath without leaving anything obvious from the ground. That hidden damage shortens the roof's life and sets up leaks years down the road. By the time water is showing up inside, the storm that caused it may be long forgotten.

Chesterfield sits in the path of some of Missouri's worst straight-line wind events, including the derecho-type storms that push through the Missouri River valley in late summer. Winds do not have to reach tornado strength to lift shingle tabs and break the adhesive seal. Once that seal is broken, wind keeps working on the shingle from underneath, and the damage spreads further than the original failure point.

The high-wind storms that move through West St. Louis County push water sideways under shingles, around step flashing, and into penetrations that handle normal rain just fine. A roof that performs perfectly in a standard rain event can leak badly when water is driven upward at 60 mph. These intrusion leaks often show up as ceiling stains one or two days after the storm, not during it.

Chesterfield's heavily wooded neighborhoods and the tree canopy along the Chesterfield Valley make debris impact a real concern after any significant storm. A branch does not have to punch through the deck to cause serious damage. Glancing impacts crack shingles, compress the mat, and create stress fractures that let water in slowly. Any visible debris on the roof after a storm warrants a professional look.

DAMAGE IS RARELY VISIBLE FROM THE DRIVEWAY
From the first call to a repaired roof, here is exactly what to expect.
We climb the roof, walk every slope, and photograph everything we find: hail strikes, lifted shingles, granule loss, flashing gaps, and penetration damage. You get an honest report even if our answer is that there is no damage worth filing on.
If storm damage is present, we compile a written report with date-stamped photos and a hail and wind history pull for your specific address. That documentation is what your insurance adjuster needs before they will open a claim.
We walk you through what storm date to reference, what to say to your carrier, and what not to sign before the adjuster has visited the property. This is the part storm-chasers count on homeowners not knowing.
When your adjuster arrives, we meet them on the roof. Walking through the damage together cuts down on missed items and supplements later. Most adjusters appreciate having a knowledgeable roofer present.
Once the claim is settled, we schedule the work with local crews, manufacturer specs, and a full tear-off when the slope calls for it. Every job is backed by the 10-Year Gorilla Guarantee.
Most of our Chesterfield storm work comes from neighbors referring neighbors. That is the only referral program that matters.

Thanks very much to Matt, who came out in Dec. 2024, thoroughly assessed our problem (even popping into the attic to confirm what was going on), and helped us sort out a leak we'd been chasing for months. Honest, thoroug…

They were upfront from the start — told us we only needed a repair, not a full replacement. Saved us thousands. Most contractors would've pushed for the bigger job. Gorilla earned our trust and our business going forward…

From the first inspection to the final cleanup, the communication was outstanding. Our new roof looks incredible and the crew finished a day ahead of schedule. Couldn't be happier.

After the hailstorm last spring, Gorilla walked us through the entire insurance process. No pressure, no gimmicks. They handled the adjuster meeting, the paperwork, and the install. We just had to sign things.

Within 30 days is ideal. Most insurance carriers will still accept a storm-related claim up to one year after the event, but the sooner you get documentation, the easier it is to tie the damage to a specific storm date. Waiting also risks further damage from weather getting into compromised areas.
Not necessarily. Hail damage can fracture the shingle mat and strip granules without causing an immediate leak. That hidden damage shortens the roof's useful life significantly. The leak often shows up years later, long after the storm that caused it. An on-roof inspection is the only way to know for sure.
Do not sign anything before you have had an independent inspection and filed the claim yourself. Storm-chasers target Chesterfield neighborhoods within hours of a major event. Some are legitimate, many are not. A local roofer who has offices in Chesterfield has far more incentive to do the job right.
Usually yes, as long as the damage is storm-related and the roof was compliant when installed. Some policies pay actual cash value on older roofs rather than full replacement cost, meaning depreciation is applied. Check your policy for the words 'actual cash value' versus 'replacement cost coverage' before you file.
It happens more than people expect. We can request a re-inspection with a different adjuster, submit supplemental documentation, or refer you to a public adjuster for more complex disputes. Most disagreements get resolved without escalating further.
A free inspection typically happens within a few days of your call. Once a claim is filed, adjuster visits usually occur within one to two weeks. After claim approval, scheduling and installation vary by season and scope, but most residential replacements are completed in a single day once materials are on site.
We climb the roof, document what is there, and tell you straight whether it is worth filing on. No pressure, no door-knocker games.

More than a promise — it's our commitment to unmatched craftsmanship and total transparency. We stand by our work 100%, no exceptions.
