Winter Storm Damage Roof Repair Checklist for Illinois Homeowners

Winter storms in Illinois can be harsh. Heavy, wet snow, ice build-up and freeze-thaw cycles put stress on shingles, flashing, gutters and the attic. We wrote this checklist for Mount Prospect and the nearby NW suburb communities so you know exactly what to check after a winter storm, what to fix right away, and what can safely wait until spring.

Before you climb always think safety first

Never climb onto a snowy or icy roof. Slips are common and dangerous. From the ground, use binoculars or a good vantage point to look for obvious problems missing or curled shingles, broken vents or areas where snow is sliding off in chunks. If you see large tree limbs that have cracked and landed on the roof, keep everyone inside away from that part of the house and call a pro. For interior signs watch ceilings, attic insulation, and walls for fresh water stains or sagging. These are the earliest clues a roof has let water in.

Immediate post-storm checklist to do right away

Quick exterior scan from ground level

Walk around your house when it’s safe and dry. Note any missing roofing material, visible holes in flashing around chimneys or vents, downed gutters, or debris on the roof from trees. Photograph everything, clear photos taken from the ground are extremely helpful when you call us.

Check the attic for leaks and stains

Go into the attic with a flashlight during daylight (if safe). Look for wet insulation, dark streaks, damp wood, or light coming through the roof. Mark any wet spots with painters’ tape so technicians can find them quickly. Small attic leaks can become big problems fast; if you spot wet spots, call us to schedule an inspection.

Clear accessible downspouts and entrances

If ice or snow is blocking gutters and downspouts at the ground level, carefully clear them once temperatures allow. Standing water that can’t drain will freeze and make ice dams worse. Don’t chip at ice on the gutters with a hammer that can bend and damage them. If gutters are pulled away or torn, they should be secured or temporarily supported.

Look for ice dam signs

Ice dams form when warm attic air melts snow on the upper roof but it refreezes at the eaves. Look for long icicle lines and snow-melt runoff inside the attic or along the soffit. If you suspect ice dams, don’t use unsafe methods to break them, call us. We provide proven solutions (ventilation, insulation, targeted repairs) to help stop repeat problems.

Temporary fixes we can do right away

When leaks are active, we can apply temporary tarps or targeted sealants to stop water entry until a permanent repair is scheduled (If weather permits). These are emergency measures designed to prevent interior damage; they’re fast, effective, and done safely by our trained crews.

What to document

Take clear photos of damaged areas, the inside ceiling or attic stains, and any displaced gutters or debris. Record the date and time of the inspection and write brief notes about what you saw. This log helps our crew triage the urgency and plan an efficient repair when we arrive. (We use records like this in our maintenance files for local homes, and it speeds up service calls.)

What a professional should check

When you schedule an inspection with Peterson Roofing, our techs will:

• Walk the roof when safe and clear, checking shingles, flashings, ridges and valleys.
• Inspect chimney and vent flashings and sealants for gaps.
• Test gutters, downspouts and drip edges for attachment and flow.
• Inspect attic insulation and ventilation to identify temperature imbalances that promote ice dams.
• Search for concentrated wear, like granule loss on shingles or hammered nails that have popped up.

Repairs that should be done right away

Active leaks

If water is coming in, stop the leak. Even a small drip can damage drywall, insulation and electrical systems. We’ll install an emergency patch or tarp (If weather permits) and schedule the permanent repair

Detached or torn flashing

Flashing around chimneys, vents and skylights directs water away. If it’s loose, bent, or missing, fix it now; water will find this path every freeze-thaw cycle.

Sagging or compromised gutters

When gutters pull away they let water spill where it shouldn’t and create ice hazards. Re-secure or replace damaged sections immediately to restore proper drainage.

Heavy branches resting on the roof

A large limb held by snow can puncture roofing or shift structure. Have it removed safely by professionals.

Large areas of missing shingles or exposed underlayment

Large gaps let water and wind enter and should be repaired quickly to avoid interior damage.

Repairs that can wait until spring unless they worsen

Some issues are inconvenient but not immediately catastrophic. We’ll evaluate and let you know if a delay is safe.

Minor shingle loss around edges where no active leak is present

If the underlying deck is sound and there’s no sign of water intrusion, it’s usually safe to plan replacement in spring.

Small cosmetic damage or isolated granule loss

Granule loss signals aging, but if there’s no leak and flashing is intact, monitor and schedule full replacement planning for warmer weather.

Non-critical gutter cleaning or replacement when sections are functional

If gutters are flowing and attached, you can wait for clearer conditions in spring to replace entire runs.

Minor attic condensation without active leaks

Sometimes winter condensation shows as frost or surface dampness; improving ventilation and insulation is a spring task unless it’s causing active dripping or mold.

Ice dams

Ice dams can produce leaks even in otherwise healthy roofs. If you have repeated ice dams, the permanent fix usually includes improving attic insulation, balancing ventilation, and repairing damaged shingles/flashings at the eaves. Short-term removal can help but must be done safely; we offer long-term solutions to prevent a repeat.

Why timely, local repairs matter

Winters in Illinois are different from milder climates, repeated freeze/thaw cycles and heavy, wet snow accelerate damage. Addressing active leakage and compromised flashing quickly prevents mold, structural rot, and higher repair bills later. We recommend routine spring and fall checks as part of our maintenance program to catch issues before storms hit.
