Crushed Insulation Under The Sheet
Hail compresses foam board under a membrane that still looks fine. Foot pressure finds the soft spots, and cores confirm how deep the damage goes.

As a Vincennes commercial roofing contractor, we install and replace roofs on Knox County offices, shops, and plants, and check them closely after hail.
Vincennes commercial roofing calls often start after a spring storm, when owners need to know what the hail did under the membrane.

Hail rarely leaves a hole you can see. It crushes the insulation under a membrane, cracks aged TPO, dents metal panels, and shatters skylights, and much of that shows up only when you walk the roof or cut a core.
After a storm we walk every section, mark bruised areas, and core them, so a repair, a replacement, or an insurance claim rests on what was actually found.
The marks hail and wind leave on Knox County roofs.
Hail compresses foam board under a membrane that still looks fine. Foot pressure finds the soft spots, and cores confirm how deep the damage goes.
Older TPO and EPDM lose flexibility and crack where stones land. The fractures are fine, so they show only up close with the surface wet.
Dents on steel panels mostly matter where they open a lap or crack the paint finish. Rust follows the cracked paint within a few seasons.
Translucent panels break in hail and leave open holes in the roof. They are also a fall hazard for anyone walking up there.
Light metal caps on vents and exhaust dent closed or split. Water then runs straight down the duct into the building.
Storm winds peel edge metal and the membrane behind it. A loose edge left alone grows into a large blow-off in the next storm.
Gains that matter on a roof that takes spring storms.
New insulation replaces the crushed board, and the new membrane sits flat over it. Ponding in hail dimples ends.
Heavier membrane or a cover board under it stands up better to stones. The scope lists the thickness so you can compare bids.
Replaced skylights or screens over them close the most common hail opening and the fall hazard with it.
Cores, photos, and a roof plan from the inspection give your carrier the facts behind the claim.
All four systems, chosen for how they handle hail.

Thicker TPO over a cover board gives Vincennes store and office roofs more resistance to stones than thin sheets laid on bare foam.

Rubber membrane flexes under impact, and on Knox County offices it can be fully adhered over a firm board.
Evansville EPDM roofing
Plant roofs after a storm need units, hoods, and stacks checked as closely as the field. Industrial roofing handles both.

Heavier-gauge steel panels resist denting, and standing seam keeps fasteners out of the weather on shops and warehouses.

From storm check to finished roof in four steps.


We walk every section, mark soft and cracked spots in paint, and photograph skylights, hoods, and edges for the file.
Cores cut through marked spots show crushed or wet board. Each one is patched before we leave so the roof stays dry.
Small, isolated damage gets a repair scope. Damage across the field gets a replacement scope with system and thickness listed.
New board, membrane, and flashing go down area by area, each sealed daily, with skylights and hoods replaced as needed.
We also roof shops, plants, and civic buildings in these towns. Outside them? Call us or send us a message.
Storm, coverage, and selection questions from Knox County owners.
Any storm with stones big enough to dent cars or gutters is worth a roof walk. Bruising under the membrane gets worse with each freeze, so finding it early keeps a repair small. Photos and cores taken soon after the storm also give your insurer clear dates and findings.
It can, and most of the damage hides. Stones crush insulation under the membrane, crack older TPO, dent panels, and break skylights. From the ground the roof looks fine, so after a storm we walk it and cut cores where bruising is likely, and any repair or claim rests on those findings.
Yes, on flat and metal roofs over Vincennes offices, shops, and industrial buildings. Drainage, the layers already on the roof, and the deck all get checked before we suggest TPO, EPDM, or metal. Owners in other Knox County towns can call and ask about their building.
Churches and schools in and around Vincennes get the same roof walk and written scope as offices and plants. Work days are set around services and class schedules, and the scope notes any entrances that need protection while roofers work overhead.
Ask for a roof walk with cores before any price, a written scope with system and thickness, and a plan for keeping the building open. After hail, ask whether the findings will be photographed and written up for your insurer. Compare scopes line by line before comparing totals.
It starts with a storm check and cores, then either a repair of the damaged areas or a full replacement where the damage spreads. Skylights, hoods, and edge metal are included in the scope where hail or wind hit them.
Send the address and the storm date if you know it. We walk the roof, cut cores, and write up what the hail did.
