The Short Answer
In West Michigan, check the roof once the snow is gone and before the late spring storms, usually from mid-April into May. Stay off the roof. Walk the yard with binoculars looking for missing, creased or lifted shingles, bent flashing and cracked pipe boots. Check what washed out of the downspouts. Then look in the attic on a sunny day for daylight and after a rain for wet wood, and check ceilings near exterior walls for ice dam stains.
Key Points
- In Grand Rapids the median last measurable snowfall is around mid-April and the median last 32 degree night is around the end of April, so mid-April to May is the natural window.
- Everything on this checklist can be done from the ground, a ladder at the gutter line, the attic or inside the house.
- Ice dam damage usually shows up near exterior walls; freeze-thaw and wind damage shows up at shingle edges, nails, boots and flashing.
- Photograph and date what you find, because Michigan insurers expect prompt notice and reasonable steps to limit further damage.
- Small items caught in spring are cheaper to fix together in one visit than one at a time after the summer storms.
When to Do a Spring Roof Check in West Michigan
The check works best once the roof is clear of snow and ice, the gutters have thawed and drained, and you can stand in the yard without slipping. In the federal daily records for the Grand Rapids airport, the median date of the last measurable snowfall from 1991 to 2020 was about April 12, and the median last night at or below 32 degrees was about April 29. Some years end much earlier and some much later: in that span the last freezing night came as early as April 12 and as late as May 25.
That makes the second half of April into May the natural window for most homes. It also comes just before the wetter months. April and May each average about 4 inches of precipitation at Grand Rapids, well above March's 2.4 inches, and spring thunderstorms bring the year's first strong winds and hail. A roof that has been checked and patched before then is far less likely to turn a spring storm into a ceiling stain.
If something is obviously wrong before then, such as a shingle in the yard, water in the house or a sagging section, do not wait for the calendar. Call a roofer and handle the urgent part now.

Do the Whole Check Without Walking the Roof
A spring roof is a bad place to walk. Shingles are brittle in the cold, moss and algae are slick when wet, and shaded slopes can hold frost or ice into late morning. Falls from roofs and ladders are among the leading causes of serious injury in construction, and homeowners do not have the anchors and harnesses a crew uses. Everything below can be done from the ground, the attic or a ladder set at the gutter line.
If you use a ladder, follow OSHA's basic rules for portable ladders: set the base out one foot for every four feet of height to the support point, extend the ladder at least 3 feet above the edge you are working at, keep three points of contact while climbing, and look for overhead power lines before you raise it, especially the service drop to the house. Do not step from the ladder onto the roof. A pair of binoculars and a phone camera with zoom will show you nearly everything a quick walk would.
What to Look for Walking Around the House
Walk the full perimeter, then cross the street or go to the back of the yard for a view of the upper slopes. Morning or late afternoon light, coming in low across the roof, makes lifted edges and creases easier to see. Take photos as you go so you can compare them with last fall.
- Missing shingles, or bare strips of dark underlayment or wood showing through.
- Creased or lifted tabs, usually along rakes, ridges and the windward side, where wind caught a shingle that was not sealed.
- Small bumps or holes in the shingle surface, which are often nails that have backed out over the winter.
- Ridge caps that are cracked, split or missing; they are the most exposed shingles on the roof.
- Flashing at chimneys, walls and dormers that is bent, loose, or has dried sealant pulled away from the brick or siding.
- Plumbing vent boots with a cracked or split rubber collar, and vent hoods that are dented, loose or missing.
- Drip edge that is bent or pulled away at the eaves, often from ice or a heavy gutter.
- Gutters sagging, separated or pulled away from the fascia after holding ice. Gutter repair is another trade, but note it for the roofer, because ice-loaded gutters also damage the roof edge.
- Shingle pieces, nails or flashing scraps in the yard or flower beds below the roof.
- Moss, especially on north slopes and under trees, and any shingles it has lifted.
Read What Winter Washed Out of the Gutters
The gutters and the splash area under each downspout are a record of what came off the roof over the winter. Before you flush them, take a look. A handful of granules is normal on any asphalt roof, especially a newer one. Heavy drifts of granules, enough to make a dark sand pile at a downspout, suggest aging shingles or surface damage worth a closer look.
Other things that turn up there tell their own story. Pieces of shingle mean something broke. Nails mean fasteners are working loose. Bits of sealant or roof cement mean a patch somewhere has let go. Note which downspout they came from, because that tells you which part of the roof to look at with the binoculars.
The Attic Check, Step by Step
The attic shows what the outside cannot: whether water got through. If you can reach it safely, plan two short visits, one on a bright day and one within a day after a good rain. Step only on framing, not on the drywall or plaster between it, and wear a mask in dusty insulation.
- Step 1
Look for Daylight
On a sunny day, turn off the attic light and look up. Pinpoints of light around nails, pipes, chimneys or along the eaves mean openings that water can find. Light along a ridge vent is normal.
- Step 2
Check the Eaves First
Shine a flashlight down to where the roof meets the outside walls. Dark streaks, rust on nail tips or water-stained sheathing there are the classic signs of ice dam backup.
- Step 3
Follow the Penetrations
Check around the chimney, plumbing vents, bath fan ducts and any skylight wells. Stains that run down from a penetration usually point to its flashing or boot.
- Step 4
Feel the Insulation
Flattened, matted or damp patches of insulation mark where water has been landing, even if the ceiling below looks fine.
- Step 5
Look Again After Rain
Wet wood after a rain points to a roof leak. Wet wood after a thaw with no rain, or many small drips at nail tips, more often points to condensation.
Ceilings and Walls Tell You Where Ice Dams Leaked
Ice dam leaks have a recognizable footprint. Water backs up under the shingles at the eave and comes into the house just inside the exterior wall, so the stains show along the top of exterior walls, at the corners of upstairs ceilings, above windows and sometimes as peeling paint or swollen trim on the outside wall below the eave. The University of Minnesota Extension notes that ice dam water can damage walls, ceilings and insulation, and that moisture left behind can lead to mold.
Check closets and rooms you rarely use, which is where a winter leak often goes unnoticed. Then check around chimneys, skylights and bathroom ceilings, which point to flashing and boot problems rather than ice. If you find wet drywall or insulation, it needs to dry. The EPA's mold guidance is to dry water-damaged areas and items within 24 to 48 hours to prevent mold growth, and drying or replacing interior finishes is a job for a restoration or drywall contractor, not a roofer.
Fix Now, Fix This Season or Keep an Eye On
Not everything you find is urgent. Sorting it helps you decide what to call about today and what to bundle into one visit.
Fix now
Before the next rain
Active leaks, missing shingles that expose underlayment or wood, flashing that has pulled away from a chimney or wall, a cracked pipe boot with a stain below it, and any soft or sagging area. These let water in on the next storm.
If it's leaking right nowFix this season
Before summer storms or next winter
Creased or lifted tabs, backed-out nails, dried and cracking sealant at flashing, bent drip edge, and ice dam stains that have dried. None is a crisis today, but each gets worse with wind and next winter's freeze-thaw cycles.
What freeze-thaw doesKeep an eye on
Note it and recheck in fall
Light granule loss, a little moss, minor cosmetic streaking and an older roof that is simply aging. Photograph these so you can tell next spring whether they changed.
Signs you need a new roofWrite It Down Before You Fix It
Before anything is repaired, take dated photos of each problem from the ground and in the attic, plus any interior stains. Keep them with last fall's photos and any repair invoices. That record helps a roofer diagnose, helps you if a problem comes back, and matters if you think damage came from a specific storm.
Michigan's Department of Insurance and Financial Services lists a policyholder's duties after a loss, including notifying the insurer or agent as soon as possible and taking reasonable action to minimize further damage, such as covering damaged property. Most homeowners policies treat gradual wear and deterioration differently from sudden events like a wind storm, so not everything a spring check finds is a claim. If you think it might be, read your policy and call your agent before the damage is repaired, and keep receipts for any temporary protection.

Learn MoreQuestions We Hear
Is it normal to find shingle granules in the gutters every spring?
Some, yes. New shingles shed loose granules for a while, and every asphalt roof sheds a little each year. What deserves a closer look is a sudden increase, heavy piles at one downspout, or bare dark patches on the shingles themselves. Note which downspout the granules came from and look at that part of the roof with binoculars.
My ceiling stain from February is dry now. Do I still need to do anything?
Yes. A dry stain means the water stopped, usually because the ice melted, not because the cause went away. Ice dam leaks tend to repeat in the same spot every winter until the eave and the attic heat loss are dealt with. Check the attic above the stain for wet or darkened wood, and have the eave inspected before next winter.
Can I use a drone to check my roof?
A drone can give you a good look at upper slopes and chimneys without a ladder. Federal rules apply even to hobby flights: the FAA requires registering drones of 250 grams or more, passing its free TRUST safety test, and getting authorization before flying in controlled airspace near airports. A drone shows the surface only; it will not show soft decking or what is happening under the shingles.
How long can I wait to fix minor winter damage?
Minor items like a few backed-out nails or a creased tab can usually wait a few weeks to be bundled into one visit, but try to have them done before the summer thunderstorm season and well before next winter. Anything letting water in, such as a missing shingle with wood showing or a split pipe boot with a stain below, should be fixed before the next rain.
Should I clean moss off the roof during my spring check?
Not from on the roof, and never with a pressure washer; the asphalt roofing industry warns that high-pressure washing is likely to damage shingles. Moss is a sign that part of the roof stays damp and shaded. Note where it is and how thick it is, and see our moss and algae article for cleaning methods that manufacturers accept.
