Summer 2026 was hard on roofs across the Upper Midwest. Hail fell in April, June, July and August, and wind lines crossed both states repeatedly. September is the month to deal with it, because good fall roof maintenance Minnesota and Wisconsin homeowners can do in one afternoon prevents most of what goes wrong in January. Here is the checklist we run on our own inspections, written so you can do the ground-level parts yourself.
Why Fall Roof Maintenance in Minnesota Cannot Wait Until October
Sealants need warmth to cure. Shingles need warmth to seal down. Once overnight temperatures drop into the thirties, both become unreliable. In addition, every reputable crew in both states books solid by early October. Waiting therefore costs you twice: worse working conditions and a longer wait. Aim to finish inspections and repairs before the end of September.
Start With What This Summer Left Behind
Before you think about winter, deal with summer. If you live anywhere near the July 4 or August 7 storm corridors, hail damage may already be present. Our August 7 hail recap lists the affected communities. Damage from those storms is still claimable, but it becomes harder to attribute to a specific date as months pass. Handle that first, then move to maintenance.
The Ground-Level Checklist
None of this requires a ladder. Walk the perimeter of the house with binoculars and a phone camera:
- Look down each roof plane for lifted, curled, cracked or missing shingles
- Check the ridge line and hips, since cap shingles fail first under wind
- Inspect flashing at the chimney, at every wall intersection, and around skylights
- Look at plumbing vent boots for cracked rubber collars, which are a very common leak source
- Scan for dark streaking or moss on north-facing slopes, because both hold moisture
- Photograph anything questionable and note the date
Attic and Insulation: Where Ice Dams Actually Start
Ice dams look like a roof problem. In reality they are a heat problem. Warm air escapes into the attic, melts snow on the upper roof, and that meltwater refreezes at the cold eave. Water then backs up under the shingles. So the fix is almost always insulation and ventilation rather than the roof surface itself.
Check three things while you are up there. First, confirm insulation depth is even and that it has not been compressed or pushed aside. The Department of Energy recommends roughly R-49 to R-60 for attics in our climate zone. Second, make sure soffit vents are not blocked by insulation. Third, verify that bathroom and kitchen fans vent outside rather than into the attic.
Gutters, Valleys and Downspouts
Clean gutters twice in fall, not once. Do the first pass in mid-September and the second after the last leaves drop, usually late October. A gutter packed with wet leaves freezes into a solid block, and that block becomes the anchor for an ice dam. While you are there, confirm downspouts discharge at least four feet from the foundation. Also clear roof valleys, since debris there traps snowmelt.
Fall Roof Maintenance Minnesota Homeowners Skip Most Often
A few items get overlooked almost every year:
- Trimming branches back six to ten feet from the roof, which prevents abrasion and reduces ice loading
- Checking attic ventilation ratios, since many older homes have intake but almost no exhaust
- Sealing attic bypasses around recessed lights, chimneys and top plates before insulation is added
- Inspecting fascia and soffit for rot, which lets pests and moisture in over winter
- Testing heat cable if you already have it, rather than discovering it failed in January
When Maintenance Is Not Enough
Sometimes the honest answer is replacement. Consider it if your roof is past twenty years, if you have patched the same leak more than twice, or if this summer produced widespread hail bruising. Given how the last several storm seasons have gone in both states, Class 4 impact-rated standing seam metal is worth pricing. It carries a 40 to 70 year service life, sheds snow rather than holding it, and often earns an insurance discount. Ask your agent what your carrier offers.
