A November hailstorm does not have to be huge to leave a mark, and the one that crossed Rockton, IL on November 10, 2020 dropped hail of an inch to an inch and a quarter in and around the town. Hail that size bruises a membrane, cracks an aging coating and strips the granules off a mineral-surfaced cap sheet. Then the Northern Illinois winter moves in behind it, with about 134 days a year at or below freezing, and every thaw pushes meltwater into whatever the hail started. Damage that looked cosmetic in November turns into a stained ceiling tile and a wet insulation board by February.
If your building was standing in 2020 and nobody has walked the roof since, that is the first thing to fix. We will look at it, photograph it and tell you plainly what we find, including when the answer is that you are fine.
Check the roof for the hail that nobody reported
Most hail damage on a commercial roof never produces a leak the week it happens. A single-ply membrane takes the hit, the reinforcing scrim underneath takes a small fracture, and the roof carries on shedding water until the next hard freeze opens that fracture a little wider. On a modified bitumen roof, the stones knock granules loose and expose the asphalt to ultraviolet light, which dries it out years ahead of schedule. Metal panels pick up dents that look minor and sometimes break the paint finish, which is where corrosion begins. The storm that hit Rockton damaged buildings across Winnebago County on a known date, and a known date gives a claim something firm to stand on.
Walk the roof with someone who is paid to tell you the truth, not to sell a project. A careful commercial roof inspection after a known storm date gives you something to put in front of a carrier. Hail damage repair starts the same way: find the bruises, count them plainly and decide whether the roof is worth repairing.
Protect your money with a claim file before the deadline matters
A policy gives you only so long to report storm damage, and the clock keeps running while a roof leaks quietly. A Rockton owner who sat on the hail of November 2020 and then found trouble in a later winter may be asked by the carrier why the claim came so late. Paper is your best protection, and it should hold three things: photographs with dates on them, a written roof condition report, and an estimate that separates hail or wind damage from ordinary aging. A roofer who prepares insurance claim documentation builds that file, though no honest roofer can promise what an adjuster will decide.
Do not sign a contract with a contractor who offers to cover your deductible or who wants to start before the adjuster has seen the roof. Get a second opinion on any scope that looks heavy. A fair price is one you can explain line by line to a bank, a board or a landlord.
Study the drains and the heavy rain
The Pecatonica River, which has flooded repeatedly in the years after 2017, enters the Rock River at Rockton, about 15 miles north of Rockford. A river flood will not reach a rooftop, but the wet years that fill rivers also load roof drains, and Rockford itself saw a 200-year flood in July 2024 that overwhelmed its stormwater systems. On a low-slope building, a clogged drain or an undersized scupper turns a heavy downpour into standing water in a few hours. Ponded water adds weight, speeds the wear on seams and gives winter ice a place to form.
Look at the drainage before you look at the membrane. Clear the basins, check that the sumps still pitch to the drain and see whether the overflow scuppers sit at the right height. Clearing and correcting roof drains and scuppers is often the cheapest roof dollar an owner will ever spend, and it protects every other dollar spent on the roof.

- Water standing more than a day after rain
- Staining on the wall below a scupper
- Soft or spongy spots underfoot near a drain
Weigh repair, recover and replacement side by side
Commercial buildings of different ages carry roofs of different ages, and a tired built-up roof, a patched ballasted EPDM roof and a 15-year-old TPO roof each call for a different answer. Repair makes sense when the insulation is dry and the damage is local. A recover over the existing roof can work when the deck and insulation are sound and the building code allows another layer. Full replacement is the right call when moisture has spread through the insulation or when the deck itself is failing.
Ask for all three prices in writing, side by side. If a bid lists only replacement, ask why. A new TPO roofing system and a roof recover over what is there buy different things, and a contractor should be able to say what each choice buys and what it does not. Permits for a full replacement now fall under the 2021 IECC based energy code that Illinois adopted for 2024, so insulation requirements can change the number on a bid, and a contractor should be able to show you why.
Time the work around the freeze and the plant calendar
Welded seams and adhesives want mild, dry air, and in this part of Illinois that means the weeks from spring thaw to the first hard frost. Open a roof in January and the temporary protection costs real money while the building stays exposed to the next storm. Larger jobs go on the warm calendar, and winter hours are kept for emergency dry-in and targeted repair, with that plan spelled out in the estimate so nothing surprising lands on the invoice.
Rockton has working industrial neighbors, among them the Chemtool lubricant plant, and a working plant cannot lose a production shift. We plan staging, hoisting and tear-off around the schedule of the people inside, and if a flexible, tenant-occupied flex industrial building needs phased work, we phase it. The Chemtool explosion and fire of June 14, 2021, which forced a one-mile evacuation, is a reminder that a roof near heavy industry can collect soot, debris and residue, and an owner within a mile of an event like that should have the roof photographed. The same timing applies to a building near Roscoe or South Beloit, and emergency roof repair is there around the clock when a storm gets ahead of the plan. A separate property in Roscoe is inspected on its own roof and event evidence.
Questions Owners Ask
Does 1-inch hail really hurt a commercial roof?
It can. Stones that size bruise single-ply membranes and loosen granules on modified bitumen, and the damage often shows up as a leak a winter or two later. A walk with a moisture scan will tell you whether yours took a hit.
How late is too late to report storm damage from 2020?
Your policy sets the limit, so read it or have your agent send it to you. The longer the gap, the more your photos and condition report have to prove that the damage came from the storm and not from age.
Should I worry about the Chemtool fire if my roof is a mile away?
Worry is the wrong word, but a quick look is smart. Soot, debris and residue can settle on a roof near a large industrial fire, and a dated photo set protects you if a question comes up later.
What does a ponding problem near the river cost me over time?
Plenty, in slow motion. Standing water wears seams, adds load and freezes into ice that lifts flashings. Fixing the drain is usually far cheaper than replacing the membrane the water ruined.
Is Rockton close enough for same-day emergency help?
Yes. We work out of Rockford, about 15 miles south, and emergency crews respond around the clock, holidays included. The first visit dries in the building and documents the damage.
