Choosing a Storm-Damage Roofing Contractor in MI

Michigan does not require state-level roofing contractor licensing, but municipalities set their own requirements. Detroit, Grand Rapids, Ann Arbor, and Lansing each require business licenses for contractors performing work within city limits, and some require separate building trade registrations. Your contractor should provide proof of current general liability insurance with minimum $1 million coverage and workers' compensation insurance for all employees. Request certificates of insurance directly from the carrier, not photocopies from the contractor. The certificate should name your property address as the project location and list you as the certificate holder. Verify the policy is active by calling the insurance carrier's verification line. Contractors working on insurance claims should have documented experience filing supplemental claims and working with adjusters. Ask how many insurance-funded projects they completed in the past 12 months and request references from those projects specifically.

Michigan experiences an average of 15–25 hail events per year, concentrated in May through August across the Lower Peninsula. Counties along the I-94 corridor from Kalamazoo through Detroit see the highest frequency. Contractors familiar with hail damage know to inspect for granule loss, mat fractures, and shingle bruising that may not be visible from the ground. Severe windstorms from Great Lakes systems regularly produce 60+ mph gusts that lift shingles, damage flashing, and compromise ridge vents. A contractor experienced with Michigan storm damage will check attic ventilation, inspect underlayment integrity, and assess whether decking absorbed moisture during the breach. Winter ice damming is common in northern counties and along Lake Michigan's eastern shore. Contractors working in these areas should discuss ventilation upgrades, ice and water barrier placement beyond code minimum, and attic insulation improvements as part of the replacement scope.

A complete estimate separates material costs, labor costs, disposal fees, permit fees, and contingency allowances for discovered decking damage. Material costs should specify manufacturer, product line, color, and warranty tier. Labor should be itemized by square or by day with crew size noted. Disposal typically runs $300–$800 depending on roof size and landfill fees in your county. The estimate must include underlayment type and ice and water barrier coverage. Michigan building code requires ice and water barrier to extend 24 inches beyond the interior wall line in counties with heavy snow load, but best practice extends it 36 inches or to the first full course of shingles. Ask whether the estimate uses code minimum or exceeds it. Permit costs vary by municipality. Detroit charges $50–$150 depending on project value. Grand Rapids bases fees on square footage. Some townships waive permits for like-for-like shingle replacement but require them when decking is replaced or structural work is performed. The estimate should state whether permit acquisition is included in the contractor's scope.

Ask for references from projects completed in the past 18 months where the work was paid through an insurance claim. Contact those homeowners and ask whether the contractor handled supplemental claims, how long the project took from contract signing to final invoice, and whether the contractor coordinated directly with the adjuster. Request photos of completed projects in your area that show similar damage types. A contractor experienced with hail damage will have before-and-after documentation showing shingle bruising, granule loss patterns, and replaced sections. Wind damage projects should show replaced decking, re-nailed shingles, and repaired flashing. Check the Better Business Bureau profile and verify how the contractor responded to complaints. One or two complaints over several years is normal. Patterns of unresolved disputes over final invoicing, material quality, or timeline delays are red flags.

Full asphalt shingle replacement on a 2,000 square foot ranch-style home in Michigan costs $8,000–$14,000 depending on shingle quality and roof complexity. Architectural shingles with 30-year warranties run $350–$450 per square installed. Impact-resistant shingles rated Class 4 add $50–$100 per square but may qualify for insurance discounts of 10–20 percent on premiums. Two-story homes and roofs with multiple valleys, dormers, or steep pitches increase labor costs by 20–40 percent. Decking replacement adds $75–$125 per sheet of plywood or OSB, and storm-damaged roofs in Michigan average 8–15 sheets of replacement decking due to moisture intrusion around breached areas. If your insurance claim is approved, the contractor works from the adjuster's estimate. Most initial estimates are conservative. Contractors file supplemental claims when they discover additional damage during tearoff, which is common with hidden hail bruising or wind-damaged underlayment. Estimates based on available industry data; individual project costs vary by roof size, pitch, material, and regional labor rates.

Contractors who go door-to-door immediately after a storm and offer to waive your insurance deductible are violating Michigan insurance fraud statutes. Waiving the deductible inflates the claim and puts you at legal risk. Legitimate contractors explain the deductible is your responsibility under the policy terms. Avoid contractors who ask for more than 10 percent down or who request full payment before work begins. Michigan construction lien law allows contractors to file liens for unpaid work, so large upfront payments offer you no protection and increase the contractor's leverage. Contractors who pressure you to sign a contract before your adjuster inspects the damage or who offer to handle the entire claim without your involvement are assuming control of a process where you are the policyholder. You have the right to select your contractor, review all estimates, and communicate directly with your adjuster.
