Roof Maintenance Checklist for SW Suburbs Homeowners (Spring & Fall)

By AJ Roofing | April 2, 2026 | Southwest Suburbs of Chicago

A roof that receives no attention for 20 years will fail earlier than one that gets basic seasonal maintenance. In Illinois, the most important maintenance windows are spring — after winter has done its worst — and fall, before winter begins. If you haven't had your system checked recently, we recommend a free 21-point roof inspection to identify hidden issues before they become leaks.

Spring Checklist: Assess Winter's Impact

Spring inspection is about assessing damage from the season that just passed. Do this as soon as weather is consistently above freezing and the roof surface is dry enough for a professional to safely access.

Check for ice dam damage. If you had ice dams this winter, inspect the eave area from below for water staining on ceilings or exterior walls near the eave line. Inside the attic, look for staining on rafters or insulation that has been saturated and may no longer be performing. Ice dam water travels horizontally and can appear far from where the dam was located.

Inspect shingles for winter cracking. Extremely cold temperatures cause asphalt shingles to become brittle. After polar vortex events, check for visible cracks or fractures — particularly on older shingles that were already showing granule loss. Walk around all four sides of the home and look up at each slope from the ground.

Look for lifted or displaced shingles. Wind events during winter can loosen shingles, particularly along ridges and rakes. Lifted shingles — even if they haven't blown off — may have broken their factory adhesive seal and will be vulnerable to the next wind event. These need professional re-sealing or replacement.

Check gutters and downspouts. Winter ice can pull gutters away from the fascia and damage downspout connections. Walk the perimeter and check that gutters are securely fastened, properly pitched for drainage, and free of winter debris. Check downspout connections at both the top and the splash block or drain at the base.

Inspect the attic for moisture. Even without a visible interior leak, winter moisture infiltration can leave evidence in the attic. Look for staining on the underside of the roof deck, frost lines on rafters, wet or compressed insulation, and any signs of mold growth. Early detection allows remediation before mold establishes itself.

Clear debris from valleys. Leaves and debris that accumulated over fall and winter concentrate in roof valleys where slopes meet. This debris holds moisture and accelerates shingle degradation at the valley — a high-stress area to begin with. Clear these areas carefully.

Fall Checklist: Prepare for Winter

Fall is preparation time. Everything on this list is designed to reduce the risk of winter problems before temperatures drop.

Clean gutters thoroughly. This is the single most important fall maintenance task for your roofing system. Clogged gutters that freeze in winter create the ice blockages that contribute to ice dam formation and gutter damage. Clean after leaves have finished falling — typically late October to early November in our area — so you're not cleaning again after another round of leaves.

Check flashing at all roof transitions. Chimney flashing, pipe boots, skylight flashing, and step flashing at wall-to-roof transitions should all be examined for cracked or missing sealant. Fall is the right time to address failing flashing — before freeze-thaw cycles work moisture through gaps that have developed over summer.

Inspect all roof vents and attic ventilation. Confirm that ridge vents are clear and not obstructed by debris. Check that soffit vents haven't been blocked by blown-in insulation or bird nesting. Proper ventilation going into winter is critical for preventing ice dams and attic condensation.

Trim overhanging branches. Branches that hang over the roof drop debris, hold moisture against the surface, and present a wind-damage risk during ice storms and winter wind events. Trim branches to at least 6 feet of clearance above the roof surface.

Check the attic for adequate insulation. Current Illinois energy code recommends R-49 to R-60 for attic insulation. If your attic is significantly below that, adding insulation before winter both reduces ice dam risk and lowers heating costs. This is one of the highest-ROI home improvements available to SW Suburbs homeowners.

What to Look for from the Ground

Homeowners should never get on their own roofs for inspection purposes. There's too much that can go wrong, particularly on wet, cold, or steeply-pitched surfaces. From the ground, use binoculars if necessary and look for: missing or displaced shingles, dark staining on shingle surfaces (indicating granule loss), curling or lifting at shingle edges, and gutters that appear to be separating from the fascia.

When to Call a Professional

The general rule: a professional roof inspection every two to three years for roofs under 15 years old, and annually for roofs 15 years and older. After any significant storm event, an inspection is warranted regardless of the inspection schedule. If you observe any of the warning signs above from the ground — or if your spring check reveals interior evidence of moisture intrusion — call us before it worsens.

Early detection makes the difference between a simple repair and a major remediation project. Most of what AJ Roofing finds during proactive spring and fall inspections is addressed with minor repairs. The homeowners who call us only after leaks appear usually have larger projects ahead of them.
