Snow and Ice Roof Damage Repair
Rockford, IL
The winter of 1978-79 dropped 74.5 inches of snow on Rockford, IL, and the roofs under it showed owners what a roof is really built to carry. An ordinary winter is lighter, about 36 inches, but it brings roughly 134 days at or below freezing, and weight is only half the trouble. Snow settles, melts a little at midday, refreezes into a dense crust and then gets rained on in March. Fresh powder is light and wet crust is not, and that heavy layer sits where the roof has the least to spare: against parapets, beside rooftop units and in every low spot where the membrane already holds water. By the time the ice lets go, the damage is already done and the bill is yours to sort out.
Do not climb up and chip at the ice, and do not let anyone shovel down to the membrane. Have the damage found and written down first, then decide what it is worth to fix.
Find where drifts and ice settle on your roof
Wind does not spread snow evenly. It scours the open field of a flat roof and dumps the load wherever something stops it: the wall of a taller section, a penthouse, a bank of rooftop units, a screen wall around the mechanical equipment. At roughly 5.3 million square feet, the Belvidere Assembly Plant stands in a town that averages about 35 inches of snow a year, and a roof on that scale can have many different levels, each with its own drift line and its own pattern of stress. The membrane in a drift zone takes the weight, then takes the meltwater, then takes the refreeze, and that is why the seams along a tall wall are usually the first to open.
Ice does its own harm. Drains, scuppers and downspouts freeze solid, and water backs up behind the plug until it finds a lap or a loose flashing. On steeper roofs, ice builds along the eave and pulls gutters and edge metal loose as it moves. If you see ice on the surface, look at your roof drains and scuppers first, and check the edge metal and gutters before the next freeze.
Sort ice damage from ordinary wear before you pay
Snow and ice leave a particular set of marks. Shovels and ice chisels cut membranes, sometimes straight through to the insulation. Drifts crush soft insulation and leave a visible dip. Ice jacks laps apart, so a seam that looked tight in November is a split in March, and a seam that has already let go needs seam failure repair. Flashings lift off walls and curbs as the frozen sheet moves, and a lifted base flashing calls for flashing failure repair before the next thaw. Metal panels lose fasteners, and snow guards bend or shear off.
Ask any contractor to put each finding in writing with a dated photograph and a plain statement of what caused it. Some damage belongs to this winter and some belongs to years of wear, and a claim that mixes them up gets argued. Roof insurance claim assistance from a contractor keeps the two apart so your adjuster is looking at documented facts, and you can compare the repair price with the replacement price before you commit to either.
Watch for the signs of an overloaded roof
The roof tells you it is struggling long before it fails, but the signs show up inside the building. Doors that start sticking, ceiling grids that drop or pop out of line, sprinkler heads that look out of plumb, hairline cracks in block walls, and creaking or popping from the structure overhead are all reasons to stop and look. Steel joists in a long-span building can deflect visibly before they give, and a roof that has been dipping at one bay since last year has less margin than the bay beside it.
If you see those signs, move people and stock out of the area and call a structural engineer first. We can bring a crew to remove snow in controlled layers, but the engineer decides whether the structure is safe to work over.
Large buildings with open interiors deserve the most attention. A roof the size of the one over the 90,000 square foot international cargo building at Chicago Rockford International Airport, which has more than 20 truck docks, gives drifted snow a great deal of area to load, so any building of that scale should be checked early in the thaw.
Choose between a patch, a section and a new roof
A torn sheet that sits over dry insulation is a repair. A sheet that tore and let meltwater into the insulation for a month is a different problem, because wet insulation keeps releasing moisture and stays wet under a patch. Before anyone prices a replacement, get an infrared moisture survey and a few core cuts. That test is what separates a section of roof worth saving from a roof that has to come off, and it keeps you from paying for more roof than the damage justifies.
Metal roofs ask a different question. Standing seam panels shed snow in slabs, so look at what sits below them: lower roofs, walkways, entrances and loading areas. A standing seam metal roof may need snow guards or a changed layout rather than new panels.
Converted industrial buildings need the engineer too. At Colman Yards on South Main Street, five former Barber-Colman manufacturing buildings are slated for renovation in Phase 1B, and a conversion like that changes what the deck and framing have to carry. Check capacity before you add insulation, a recover or rooftop units to a structure like.
Stop the water now and finish the repair in dry weather
A winter leak is worth stopping the day you find it. Temporary work in the cold means mastic, tarps, sealed laps and a dried-in opening, and it holds the building until the weather lets a crew do permanent work. Many adhesives and sealants will not cure in the cold, so a patch made in January is a holding action and not the final answer. Call for emergency roof repair if water is coming through the ceiling, and our crews respond at any hour, holidays included.
Then plan the permanent fix for the first stretch of dry, mild weather in spring. Walk the roof after the last big melt, when ponded ice has gone and the damage is visible, and again in fall before the first freeze. A preventive maintenance program puts both visits on the calendar so snow does not catch you unprepared, and a roof that has been cleared of debris and ponding water enters winter in much better shape. A separate roof review in Downtown Rockford follows its own drainage and ice-damage evidence.
Questions Owners Ask
Who should remove snow from a commercial roof?
Nobody without a plan. A crew that knows membranes clears the snow in layers, leaves a thin cushion over the surface and stays off the drains, the edges and every curb.
How do I know the roof is carrying too much?
Look inside first. Sticking doors, sagging ceiling grids and cracks in the walls point to a structure under strain. Clear the area and call an engineer before anyone goes up.
Will insurance pay for ice damage?
Policies differ on what counts as sudden damage and what counts as wear. Read the snow and ice language before you file, and photograph the roof before anyone repairs it.
Is a January leak worth fixing in January?
Stopping the water is. A temporary seal protects the ceiling, the stock and the insulation, while the permanent repair waits for weather that lets materials cure properly.
Do flat roofs get ice dams?
Not the way a steep eave does, but ice still builds at drains, scuppers and edges, and the water it traps behind itself finds the same weak laps.
Does a metal roof need attention after a heavy snow?
Panels shed snow all at once, and that slab is what damages whatever sits below. Check the lower roofs, the gutters and the walkways, then check the fasteners.
