Michigan roof age and home insurance
Michigan lets an insurer refuse or drop a home only under written underwriting rules, and condition rules must be set without regard to the age of the structure. A termination needs 30 days' written notice with each reason.
Short answer: Michigan: home insurers must base roof-condition rules on codes, not house age, and give 30 days' written notice with each reason.
3 of 7 topics have a rule we could quote. 10 points below, 8 from statute or rule text.
Seven topics, what we found in Michigan
Condition rules must be set without regard to the age of the structure (MCL 500.2117)
No roof payment schedule rule found in the pages we opened
State guide suggests a higher deductible to cut premium; no wind or hail rule found
No cosmetic-damage rule found in the pages we opened
30 days' written notice, each reason stated; claim-count lines in MCL 500.2117
No roof-based discount mandate found in the pages we opened
Claim history can count if a condition stays unfixed after written insurer notice
"Nothing found" means we opened the official pages listed below and the topic was not there. It does not mean Michigan has no rule.
In plain English
Michigan's Insurance Code does not name a roof age. It does something broader. Under MCL 500.2117, an insurer may not refuse to insure, refuse to continue, or limit coverage for an eligible person except under underwriting rules that the section allows. One allowed basis is the physical condition of the home. Those rules must be objective, tied to the insured perils, and set without regard to the age of the structure.
So a worn roof can matter, but the rule has to point to a building code, a manufacturer's specification or a similar standard. The state's own consumer guide says the same thing in plain words: an eligible person cannot be denied insurance solely because of the age of the house. Insurers must also keep these rules in writing and apply them the same way to everyone.
The code also gives the owner a fix-it path in one place. Renewal can turn on claim history if the owner failed, after written notice from the insurer, to correct a physical condition tied to a paid claim. The notice comes first. Claim counts have a dollar line too: three paid claims in three years totaling $3,000.00 without weather claims, or $4,000.00 with them. Weather claims get more room.
Timing and reasons are fixed by MCL 500.2123 and 500.2122. A termination needs a written notice at least 30 days ahead, with the date and each specific reason. A new policy can be ended on shorter notice in its first 55 days. This page summarizes public text and is not legal advice. It does not cover wind or hail deductibles, cosmetic damage clauses, or roof payment schedules.

When hail hits Michigan
Across 14 Michigan counties the NOAA file holds 474 hail reports (2014 to June 2026). Peak month: Jul. Largest stone reported: 2.75 inches. A percentage deductible matters most in the months with the tallest bars.
| County with the most reports | Reports | Largest stone |
|---|---|---|
| Marquette County | 81 | 1.75 in |
| Washtenaw County | 69 | 2.0 in |
| Oakland County | 54 | 2.5 in |
| Bay County | 54 | 2.5 in |
| Macomb County | 38 | 1.75 in |
What a percentage deductible costs on your policy
Some policies set the wind or hail deductible as a percentage of the dwelling coverage. Put in the two numbers from your declarations page. This is plain multiplication; the rule above controls how the percentage may be used, not how much it is.
Depends on your policy. Enter both numbers to see the dollar amount you would pay first.
What changes for a homeowner
- A refusal or nonrenewal tied to the roof has to rest on an objective written rule, not on the age of the home.
- Ask the insurer for the underwriting rule it relied on. The code requires insurers to put all such rules in writing.
- Read the termination notice for the effective date and each specific reason. The code requires both.
- If the notice asks for a repair, treat it as a written notice about a physical condition. Fix it, and keep proof of the date.
- Weather claims count toward nonrenewal at a higher dollar line ($4,000.00) than non-weather claims ($3,000.00), so a single hail claim does not reach either line.
What to ask your insurer
Ask in writing and keep the replies. The box below turns these questions into a letter you can copy.
- Which written underwriting rule applies to my roof, and what code or manufacturer standard does it cite?
- Is the roof the reason for this notice, and does the notice list each specific reason?
- What is the effective date of termination, and how many days' notice was I given?
- If you want a repair, can you send that request in writing and say what counts as fixed?
- Are weather-related claims counted in my claim history for renewal, and at which total?
- Did my policy start less than 55 days ago, which allows a shorter notice period?
What we could not confirm
- Wind or hail deductibles: MCL 500.2101-2125 and 500.2826 and the DIFS homeowners guide were opened; no cap or disclosure rule for percentage deductibles was found.
- Roof payment schedules, cosmetic-damage exclusions and roof-based discounts: nothing found in the same pages.
- Michigan Administrative Code insurance rules and DIFS bulletins on roofs were not opened (no readable archive copy reached); they may hold more.
- MCL 500.2827 did not load (the site returned a captcha page), so it was not read.

Questions people ask
Can a Michigan insurer drop me because my roof is old?
In the pages we opened, condition rules must be objective and set without regard to the age of the structure. The rule has to rest on a building code or manufacturer standard.
How much notice must I get?
MCL 500.2123 says a termination is not effective unless the insurer mails or delivers a written notice at least 30 days before the termination date. A notice in the first 55 days of a new policy can take effect after 20 days.
Does the notice have to say why?
Yes. It must state the effective date and each specific reason for the termination.
Do hail claims count against me?
The code sets two nonrenewal lines for three paid claims in three years: $3,000.00 without weather claims and $4,000.00 with them.
