Is Your Roof Ready for Winter? 7-Point Checklist
Michigan winters are hard on roofs. Freeze-thaw cycles, wet snow, wind off the lakes, and ice at the eaves all look for the same thing: a weak spot.
A roof winter checklist Michigan homeowners can finish in an afternoon will not catch every hidden issue. It will catch a lot of the common ones while the weather is still mild enough to fix them. Think of it as a walk-around, not a full inspection report.
Below are seven practical checks. Do what you can safely from the ground or a stable ladder. Leave the steep pitches and icy edges to a pro.
1. Gutters and downspouts
Clogged gutters sit full of water and leaves right where ice likes to form. That is a winter problem waiting to happen.
Walk the perimeter and look for:
- Leaves, shingle granules, and debris packed in the troughs
- Downspouts that do not drain when you run a hose through them
- Sagging sections or hangers pulling away from the fascia
- Joints that drip even in light rain
Clear what you can. Make sure water exits several feet from the foundation if possible. If a section is pulling loose, note it — winter ice makes that worse.
2. Shingles you can see from the ground
You do not need to climb every slope. Binoculars from the driveway often show enough.
Look for:
- Missing tabs or bare spots
- Curled, cracked, or blistered shingles
- Dark streaks of granules collecting in gutters (some wear is normal; heavy piles can signal aging surfaces)
- Shingles lifted along ridges or near valleys
A couple of damaged shingles near an edge or valley can open a path for winter water. Small repairs in the fall are often simpler than chasing a drip in January.
3. Flashing at chimneys, walls, and skylights
Flashing is the metal or membrane transition where the roof meets something else. Those joints move with temperature. Seals dry out. Nails loosen.
From the ground, check:
- Chimney step flashing that looks open, bent, or rusted through
- Counterflashing that has pulled out of the mortar
- Wall flashing where a second story meets a lower roof
- Skylight frames with cracked sealant or obvious gaps
You cannot always tell from the yard whether flashing is sealed underneath. Open seams, rust holes, or missing pieces are enough reason to get a closer look before snow covers everything.
4. Pipe boots and roof penetrations
Plumbing vents stick through almost every Metro Detroit roof. The rubber or plastic boot around that pipe ages in the sun and cracks. When it cracks, rain and meltwater follow the pipe into the attic.
Scan for:
- Cracked or split rubber collars
- Boots that have shrunk away from the pipe
- Exposed gaps around satellite mounts, exhaust caps, or older unused vents
Pipe boot repairs are common winter leak sources. If a boot looks tired now, winter will not be kinder to it.
5. Attic clues from inside
A good roof winter checklist Michigan run includes ten minutes in the attic on a cool day.
Bring a flashlight and look for:
- Daylight shining through the roof deck or around penetrations
- Water stains on sheathing or insulation
- Frost on nails in cold weather (can point to moisture and temperature issues)
- Insulation that is thin, shifted, or compressed near the eaves
- Blocked soffit vents or stuffed insulation choking airflow
You are not trying to become an energy auditor. You are looking for obvious red flags. Soft or stained wood, damp insulation, and clear daylight gaps deserve attention before freeze-up.
6. Trees, limbs, and roof edges
Overhanging limbs scrape shingles in the wind. Dead branches drop in ice storms. Yard debris collects in valleys.
Check:
- Limbs rubbing the roof or hanging over the eaves
- Dead wood that could snap onto the house
- Valleys packed with leaves that will hold moisture under snow
Trimming trees may be a separate job from roof repair, but it belongs on a winter readiness list. Less debris and less impact mean fewer openings for water later.
7. Prior leak history and soft spots indoors
Walk the upstairs rooms and any finished attic spaces. Look at ceilings near exterior walls, around chimneys, and under bathrooms on upper floors.
Note:
- Old water stains that might reactivate
- Soft drywall or bubbling paint
- Musty smells after rain
- Rooms that always felt colder or damper near the roof line
Past leaks often return in the same place when snow and ice load the roof again. If you remember a drip from last February, mark that area on your list even if it looks dry today.
How to use this checklist without overreacting
Finding one cracked shingle does not mean the whole roof is failing. Finding several issues in the same area — say, open flashing, a stained attic bay, and a soft spot on the ceiling below — is a stronger signal to call for a repair visit.
Soft language matters here because roofs vary. Age, pitch, prior storm damage, and how the house was built all play a role. What this checklist does is shrink the chance that winter is the first time you notice a problem.
What to fix before the snow sticks
Priority usually goes to:
- Active or recent leak paths
- Open flashing and failed pipe boots
- Clogged or detached gutters at the eaves
- Missing shingles in valleys or along edges
Those are repair jobs. Targeted, practical, and timed for fall weather when crews can still work with fewer ice risks. Metro Detroit Roof Repair handles that kind of work across Wayne, Oakland, and Macomb counties.
We fix roofs. We don't sell roofs. The goal of this checklist is to help you keep the roof you have through another Michigan winter — not to talk you into anything bigger than you need.
When you should skip DIY and call
Stay off the roof if it is steep, wet, icy, or higher than you are comfortable with. Ladder falls and cold-weather slips are not worth a DIY win.
Call if you find multiple issues, if you had a winter leak before, or if you simply want someone to verify what you spotted from the ground.
