Northern Illinois puts a house through four very different tests every year: spring downpours that find every clogged downspout, summer storms with hail and straight-line wind, an autumn leaf drop that can fill a gutter in a week, and a winter of snow, ice and freeze-thaw cycles. This home maintenance checklist for Illinois takes those tests one at a time and tells you what to look at, when, and how.
Most of the list can be done from the ground, from a properly set ladder at a one-story eave, or from the attic hatch. Where a task calls for walking a roof or working two stories up, we say so plainly. A sprained wrist costs more than a service call. To keep records and log what you find, print our homeowner roof and exterior guide, which is built to pair with this page.
Illinois home maintenance checklist ground rules: DIY from the ground, pros on the roof
Before the seasonal tasks, decide where your line is. Ours is simple. Homeowners handle looking, cleaning within easy reach, and anything done from the ground. Walking roofs, working at second-story eaves, and any repair that means lifting shingles or flashing belong to a crew with fall protection and the right materials.
Reasonable to do yourself:
- Scanning the roof with binoculars from the yard or a neighbor’s driveway.
- Cleaning one-story gutters from a ladder that stands on firm, level ground.
- Flushing downspouts with a garden hose and checking where they discharge.
- Washing siding with a soft brush and low water pressure.
- Looking through the attic with a flashlight, stepping only on joists or a floored area.
- Pulling snow off the lower few feet of roof with a long-handled roof rake while standing on the ground.
Leave to a pro: anything on the roof surface itself, two-story gutters, ice dam removal, sealing or replacing flashing, heat-cable installation, large limbs over the house or near service lines, and animals living in soffits or attics.
If you do use a ladder, follow the long-standing basics: set the base about one foot out for every four feet of height, keep three points of contact, never lean it on a gutter without a stabilizer, and do not reach past the rails.
Spring (March–May): finding what winter left behind
Winter does its damage quietly. Spring is when you find out what it left, ideally on a dry, calm day after the snow is gone.
- Roof from the ground: look for missing or cracked shingles, tabs that lift in a breeze, ridge caps out of line, and metal flashing that has pulled away from the chimney or a sidewall. Note any shingle pieces in the yard.
- Gutters: ice and snow are heavy. Sight down each run for sags, loose hangers and sections pulling off the fascia. During the first good rain, step outside and watch for drips at seams and corners and for water spilling over the front edge.
- Downspouts: confirm every elbow and extension is attached and that water lands several feet from the foundation, not against it.
- Siding: walk each wall looking for vinyl cracked by snowblower debris, soft or swollen boards near grade, peeling paint on painted siding, and caulk joints that have opened around windows.
- Soffits and fascia: look for chewed holes, gaps at the corners and nesting material. Spring is nesting season, so if something is living up there, call a wildlife professional before anyone seals an opening.
- Trees: winter storms break limbs. Note anything hanging over the roof. Small branches can be trimmed from the ground; larger ones are arborist work.
Summer (June–August): storms, sun and attic heat
Summer is storm season, and also the easiest time of year to get outdoor work done. Use the warm, dry weeks for the tasks that need them.
- After every severe storm, repeat a short version of the spring walkaround (see the storm section below).
- Siding wash: mildew and grime collect on shaded north walls. Use a soft brush, mild cleaner and a hose, or a pressure washer on a gentle setting aimed level or down so water is not driven up behind the laps.
- Caulk and paint touch-ups: warm, dry weather suits exterior sealants and paint. Check the label for the product’s temperature range, and keep sealant work to what you can reach safely.
- Roof streaks: dark streaks on shingles are usually algae and mostly cosmetic. Do not pressure wash a roof; it strips the protective granules. A roofer can advise on gentle cleaning methods.
- Attic airflow: on a hot afternoon, check the soffit vents from the attic side. Insulation stuffed against them blocks the intake air that keeps the roof deck cooler and drier.
- Grills and fire pits: keep them well away from vinyl siding, which can warp from radiant heat.
If a roof or siding project is on your list, summer is also the time to collect bids so the work can be scheduled before the weather turns.
Fall (September–November): leaves, sealing and winter prep
Autumn sets up the winter. What you clear and seal now decides how your house handles ice and snow.
- Gutter cleaning: clean after most leaves have dropped. Under maples one pass may do; under oaks, which tend to hold leaves into late fall, plan a second. Bag the debris rather than dumping it at the foundation. If cleaning has become a chore you dread, read our honest take on whether gutter guards are worth it.
- Downspout test: run a hose into each gutter after cleaning. Water should flow freely out of every downspout. A blockage left in October becomes a solid ice plug in January.
- Roof valleys and low spots: leaves and seeds collect in valleys and behind chimneys, where they hold moisture against the shingles. You can spot the buildup from the ground; clearing it is a job for someone working on the roof.
- Seal entry points: check where soffits meet the roof edge and where pipes and wires enter the siding. Small gaps let mice and squirrels in when nights turn cold.
- Exterior faucets: disconnect hoses so trapped water cannot freeze back into the spigot.
- Snow plan: note where downspouts discharge so snow from driveway clearing does not bury them, and buy a roof rake before the first big storm, not after.
Winter (December–February): watch from the inside
Winter maintenance is mostly observation. Stay off the roof entirely. Icy shingles are dangerous, and walking on frozen asphalt can crack it.
- Ice dams: a thick ridge of ice along the eaves, often with heavy icicles, means heat is escaping into the attic and melting snow higher up. Watch ceilings and the tops of exterior walls for stains. Do not chip at the ice with tools. Our guide to ice dams explains the causes and the lasting fixes.
- Roof rake: after a heavy snowfall, pull snow off the first few feet above the gutters while standing on the ground. Pull gently and leave a thin layer so the rake does not scrape the shingles.
- Gutters: long icicles and gutters bending under ice are worth a photo and a note for spring repairs.
- Siding: keep shoveled and plowed snow from piling high against walls, especially fiber cement and engineered wood, which need their bottom edges to dry out.
- Attic on a cold morning: frost on roofing nails or sheathing, or damp insulation, means warm indoor air is leaking upward. Note where it is heaviest; that is where air sealing should start.
The attic check: twice a year, fifteen minutes
The attic shows problems long before a ceiling stain does. Go up once in spring and again in late fall with a good flashlight and a phone for photos.
- Look up at the sheathing. Dark rings, white mineral trails or soft-looking plywood mark past or present leaks. Pay close attention around chimneys, plumbing vents and valleys.
- Check the exhaust ducts. Bathroom and kitchen fans should run through ducts that end outside the house, not blow into the attic. A disconnected duct pumps moisture straight onto the roof deck.
- Check the intake vents. You should see daylight or baffles at the soffits. Insulation packed against the eaves chokes airflow.
- Check insulation depth and evenness. Low or bare spots let heat reach the roof and feed ice dams.
- Sniff. A musty smell points to moisture, even before you can see it.
Photograph anything that changes between visits. A series of dated pictures is far more useful to a roofer than a memory of “it looked different last year.”
Any season: the hour after a hail or wind storm
Severe storms do not keep to a calendar. When one passes, wait until it is fully over and the lightning has moved off, then:
- Look for dents on soft metals: gutters, downspouts, roof vent caps and the fins of the air-conditioning unit. They show hail size and direction better than shingles do from the ground.
- Check siding on the side that faced the storm for cracks, holes or chipped paint.
- Walk the yard for shingle pieces, granules washed out of downspouts, and fallen limbs.
- Take dated photos of everything, including close-ups next to a coin or ruler for scale.
- Inside, check ceilings under the attic and around skylights over the next few days, since leaks can take time to show.
If you find damage, a professional roof inspection documents what the ground view cannot. If you file a claim, your insurer decides coverage; a contractor’s role is documentation.
Questions readers ask
How often do gutters need cleaning in the Chicago suburbs?
At least twice a year: in late spring after seeds and blossoms drop, and again in late fall after the leaves. Homes under large oaks, maples or pines often need a third cleaning. Watching your gutters during a heavy rain is the quickest test. Water spilling over the front edge means it is time.
Is it safe to clear snow off my roof myself?
Only from the ground with a roof rake, and only along the lower few feet of the roof. Climbing onto a snowy or icy roof is one of the most common ways homeowners get hurt in winter. If snow and ice are deep enough that you are worried about weight or leaks, call a roofing crew equipped for it.
Should I pressure wash my roof to remove black streaks?
No. High-pressure water strips the granules that protect asphalt shingles from sunlight and can force water under the laps. The streaks are usually algae, which is mainly a cosmetic problem. Ask a roofer about gentle cleaning methods, or about algae-resistant shingles the next time the roof is replaced.
What does a professional maintenance visit cover that I cannot see from the ground?
A roofer on the roof can check sealant at pipe boots and flashing, lift and inspect suspect shingles, clear valleys, look at the condition of ridge vents, and spot hail bruising that is invisible from below. Pairing that visit with your own seasonal checks catches most problems while they are still small repairs.
