Michigan Spring & Summer Exterior Prep Guide: A Homeowner's Checklist After the Thaw

The job most Michigan homeowners do in November isn't the only one their house needs. After six months of freeze-thaw, road salt film, and falling debris, the same roof and the same exterior that the fall cleaning protected are due for a second pass — and the homeowners who book it in late spring catch the problems that winter creates but doesn't fix. A professional window washing, a post-winter roof inspection, and a late-spring gutter check and re-clean are the three services Michigan homeowners most consistently book together between mid-May and the end of June.

Window washing season timing: getting windows right between pollen and summer storms

Across Oakland County — Bloomfield Hills and Birmingham especially — homeowners schedule exterior window washing the same week they notice pollen has stopped sticking to the cars and patio furniture. That's not a guess; it's the natural end of the oak-and-maple pollen push that coats every west-facing window from late April through mid-May. A professional window cleaning service between late May and mid-June removes both the winter's road-salt film and the fresh pollen residue in a single visit, so the windows stay clean through the longest stretch of summer sunlight.

The mistake Michigan homeowners make is washing too early. Book the visit for mid-May and you'll see white film reappear within a week. Book it for late May or early June and you're past the worst of the pollen push and ahead of the heavy summer thunderstorms that streak the glass.

• Road salt film. The white haze that builds on lower panes over winter contains calcium chloride residue that doesn't rinse off with a garden hose. It needs a squeegee pass with a proper cleaning solution.
• Pollen film. Oak and maple pollen in Oakland County runs late April through mid-May. Once the trees stop shedding, the residue sticks until the next rain — and the next rain doesn't lift it cleanly.
• Hard water spots. Sprinklers hitting windows bake calcium into the glass over a single summer. The longer they sit, the harder they are to remove without a professional pad.
• Screens. Winter storms pack dust and grit into the mesh. A wash that doesn't include a screen rinse leaves grit on the sill that streaks the next rain.

FAQ: When is too early to wash exterior windows in Michigan? Before mid-May is too early. The pollen push is still running, and a clean window will film over again within days. The right window is post-pollen, pre-thunderstorm — roughly late May through mid-June.

FAQ: Should I wash windows before or after pollen season? After. Washing during pollen season is wasted effort; the next rain leaves another film. Wash once after oak and maple pollen have finished, and the windows stay clean through the drier weeks of summer.

Post-winter roof inspection: what Michigan homeowners can see from the ground

Homeowners in Auburn Hills and Royal Oak see one of two things after the thaw: a roof that came through winter cleanly, or a roof that shows the early signs of freeze-thaw damage. The second group is bigger than most people think — a professional roofing inspection after the thaw catches the issues that are cheap to fix in spring and expensive to fix in midsummer.

Most post-winter roof damage is visible from the ground; you don't need to climb a ladder to spot it. Walk the perimeter of the house once after the last hard frost and look up at the roofline.

FAQ: What winter damage shows up first on a Michigan roof? Lifted shingles along the eaves, pulled flashing around chimneys, and missing ridge cap shingles. These are all visible from the ground after the thaw and are all faster to fix in spring than in midsummer when crews are booked out for storm work.

FAQ: Do I need a full inspection or just spot repairs for a Michigan roof? If only one or two shingles are lifted and the rest of the roof is intact, a spot repair is enough. If multiple courses are showing damage or the flashing is pulled on more than one penetration, a full Michigan roofing inspection is the cheaper path — spot repairs on a failing roof add up fast.

The late-spring gutter check: what the fall cleaning leaves behind

Homeowners in Rochester and Troy who book a fall cleaning often assume they're done until the next November. That's not how Michigan gutters work. Between leaf drop in November and the next leaf drop in October, the system sees ice, snowmelt, and a full season of seed-and-blossom debris. A late-spring gutter check and re-clean catches what the fall visit left behind and what winter added.

The pattern is consistent: the June clean catches shingle grit that washed down over the winter, blossom petals and seed husks that fell in May, and the residue from the first few thunderstorm cycles. Without it, all of that sits in the gutter through the heaviest rain months of the year.

• Shingle grit from winter ice. Freeze-thaw releases a surprising amount of asphalt granules over a single winter. The grit sits at the bottom of the gutter run and blocks the downspout outlet within weeks of the first storm.
• Maple seed and blossom petals. May in Michigan drops maple helicopters and blossom petals for two to three weeks. They're small enough to slip past the downspout screen and settle at every corner.
• Sagging runs after ice weight. Heavy ice loaded onto a loosely-hung gutter pulls the pitch off. A post-thaw pitch check is what catches it before the spring storms fill the gutter faster than it drains.
• Miter seals split by freeze. The inside corners are the most weather-exposed joint on the system. A seal that survived the fall will often fail through a single Michigan winter.

FAQ: Is the late-spring gutter cleaning as important as the fall one in Michigan? Yes, for a different reason. The fall cleaning protects the gutter through freeze-thaw. The spring cleaning protects it through the hardest rain months of the year. Skipping either one ends with water in the basement or against the foundation.

FAQ: How do I know if I missed the spring gutter window? Two tells: water spilling over the front of the gutter during a normal rain (not a cloudburst), and downspouts that burp instead of flowing steadily. Either one means the system has debris the fall cleaning didn't catch and the spring rains are pushing it past capacity.
