Roof inspections in Ohio and Michigan: what's checked, how often, and what you get
What a residential or commercial roof inspection covers, how often to schedule one in freeze-thaw country, what a good report includes, and red flags to avoid.

Key takeaways
- An inspection should end with photos and a written list of findings, not just a verbal opinion.
- Spring and fall inspections catch winter damage and prepare the roof for the next freeze.
- A good inspection separates repairs you need now from items to plan and budget for.
A roof inspection turns guesses into a list. Instead of “the roof is old,” you get what’s wrong, where, how urgent it is and what it will take to fix. In Ohio and Michigan, where freeze-thaw cycles and ice dams work on every roof each winter, a regular inspection is the cheapest roofing you’ll ever buy.
What a residential inspection covers
From outside and on the roof (by the inspector, not you):
- Shingle condition: curling, cracking, granule loss, missing or creased tabs, hail bruises.
- Flashing at chimneys, walls, skylights, vents and valleys.
- Drip edge, gutters and downspouts, and whether water drains away from the house.
- Pipe boots and roof vents, which are common leak points as their rubber ages.
- Signs of soft decking: sags, spongy spots, uneven lines.
From inside:
- The attic: stains, daylight, damp or matted insulation, frost on nails, mold.
- Ventilation: clear soffit intakes and exhaust vents, and bath fans vented outside.
- Ceilings and walls below the roof for stains.
What a commercial inspection covers
Low-slope roofs fail differently. A commercial inspection looks at:
- Membrane and seams: open laps, loose welds, blisters, splits, shrinkage at edges.
- Flashings and edges: walls, curbs, parapets, coping and metal edges.
- Penetrations: pipes, conduits, HVAC curbs and pitch pans.
- Drainage: drains, scuppers, gutters and ponding water that sits more than a couple of days.
- Rooftop equipment and traffic damage from service work.
- Moisture: visual clues plus, when needed, an infrared, capacitance or nuclear moisture survey confirmed with cores.
The NRCA’s preventive maintenance guidance, summarized by GSM Roofing, stresses regular inspections and prompt repairs as the core of extending a roof’s life.
How often to inspect in freeze-thaw country
| Property | Suggested rhythm |
|---|---|
| Home | Once a year, plus after hail or high wind |
| Commercial, church, school, municipal | Spring and fall, plus after storms |
| HOA or condo community | Spring and fall, rotating through buildings, plus after storms |
| Roofs with heavy equipment or kitchen exhaust | Quarterly checks around the equipment |
Spring finds what winter did: ice dam damage, cracked flashing, wind damage and clogged drains. Fall gets the roof ready: clear drains and gutters, reseal flashing and fix small openings before water can freeze in them.
What a good inspection report includes
- Date, property and who inspected.
- A roof sketch or aerial image with problem areas marked.
- Photos of each finding, close up and in context.
- Each finding ranked: fix now, fix soon, monitor.
- Estimated remaining life, stated as a range with the reasons.
- Recommendations that separate repair, maintenance and replacement.
If the only thing you get is “you need a new roof” with no photos, get a second opinion.
Red flags
- An inspector who won’t show you photos of the damage.
- Pressure to sign a contract on the spot, especially right after a storm.
- An offer to waive or cover your insurance deductible.
- Findings that are all “replace” with nothing to monitor or repair.
After the inspection
For a home, bring the findings to the roof replacement planner or the repair triage. For a commercial or association roof, log findings in the inspection intake, then compare an inspection program, maintenance plan, coating and replacement in the commercial roof cost planner. The preventive maintenance cost analysis from D. C. Taylor Co. is a useful read on why planned inspections usually cost less than reactive repairs.

Run your numbers
Quick roof estimate
Provisional planning range (our setting, not a quote or market average). Real prices depend on condition, access and scope.
What this estimate does and doesn't cover
- It all depends on the roof. Condition, material, pitch, number of layers, access and local code can move the price well outside this range. Treat it as a first budget number, not a price.
- Roof area is a rough guess. We turn living area into roof area using your stories, a 10% allowance for overhangs and your pitch. Garages, porches, dormers, valleys and complex shapes are not counted. A measurement report or an on-site measurement will differ.
- The dollar band is our own provisional setting, informed by published guides. It is not a verified Ohio or Michigan market average, not a contractor quote and not an offer.
- Assumes a straightforward replacement: one layer torn off, standard underlayment, ice barrier at eaves, flashing and cleanup.
- Not included: rotted decking, extra layers, framing or structural repair, major ventilation changes, chimney work, skylights, gutters, permits, steep or difficult access, and insurance-related work.
- Repairs are not priced. Leaks, storm damage and small repairs need an inspection.
- Stay off the roof. Measure from the ground or plans, and get a written proposal from a licensed, insured contractor before you decide.

Roof inspections in Ohio and Michigan: common questions
How often should a roof be inspected?
For homes, once a year and after major hail or wind storms is a sensible rhythm. For commercial and association roofs, twice a year (spring and fall) is common, plus after storms. The NRCA recommends regular inspections as part of preventive maintenance.
How long does a roof inspection take?
A typical house takes under an hour. Large commercial roofs can take several hours or more, especially with a moisture survey.
What is the difference between a free inspection and a paid one?
A free inspection is usually a contractor's visual assessment offered at no charge. Paid inspections, such as infrared moisture surveys, engineering assessments or insurance-related reports, go deeper and produce formal documentation. Ask what you will receive either way.
Should I be home for a roof inspection?
It helps. You can show the inspector interior stains, the attic access and where leaks happened, and ask questions on the spot.
Can an inspection tell me if insurance will cover damage?
No. An inspector can document damage and its likely cause. Coverage decisions belong to your insurer under your policy.
