Roofing Contractor Insurance in Michigan — LARA Licensing, WC at 3 Employees, and Coverage Requirements
Michigan roofing contractors are licensed through LARA with workers’ comp required at 3 employees or 35 hours per week. Hail exposure and strong mechanic’s lien laws define the Michigan roofing risk environment.
Michigan Licensing and Compliance Requirements for Roofing Contractors
Michigan roofing contractors must hold a Residential Builder or Residential Maintenance and Alteration Contractor license from the Michigan Department of Licensing and Regulatory Affairs (LARA). For commercial roofing work, a separate Contractor license is required. Michigan uses separate licensing tracks for residential and commercial work.
Michigan workers’ compensation is required when you have three or more employees OR when any one employee works 35 or more hours per week — whichever threshold is reached first. This dual-threshold approach is unique in the country. A single full-time roofing crew member working 35+ hours/week triggers the WC requirement immediately.
LARA requires proof of general liability insurance for residential builder and contractor license applications. Standard minimums vary by license type — verify current requirements with LARA. Most commercial roofing contracts in the Detroit metro area require $1M per occurrence.
Michigan’s Residential Code (MRC) and Commercial Building Code (MCBC) govern roofing work. Michigan’s contractor licensing enforcement includes permit-based inspections — roofing work on permitted projects is subject to LARA compliance review.
Roofing-Specific Risks in Michigan
WC at 35 Hours/Week — Michigan’s Unique Threshold
Michigan’s dual WC trigger — 3 employees OR one employee working 35 hours/week — catches many solo or small-crew roofers off guard. A roofer working full-time for you as a sole employee immediately triggers WC if they’re working 35+ hours/week. This is the most commonly overlooked WC compliance issue for Michigan roofing contractors.
Michigan Hail Belt Exposure
Michigan receives significant hail activity, particularly in the southeastern lower peninsula and the Grand Rapids metro area. The Detroit metro, Flint, Lansing, and Kalamazoo all see spring hail events that drive insurance restoration demand. Post-hail surge work creates completed operations exposure when jobs are rushed.
Michigan Mechanic’s Lien Law
Michigan has one of the strongest mechanic’s lien statutes in the country. Roofing contractors who properly file lien claims — and those who fail to — face different legal outcomes. A roofing contractor who files an improper lien can face penalties; one who fails to file when entitled loses payment protection. Understand Michigan lien law before starting any project.
Winter Roofing and Ice Dam Risk
Michigan winters create significant ice dam and snow load conditions on roofs, particularly in the Upper Peninsula and the snowbelt along Lake Michigan. Emergency ice dam removal, winter tarping, and cold-weather roofing work carry elevated fall risk and completed operations exposure when temporary repairs fail.

Frequently Asked Questions
What is Michigan’s unique workers’ comp threshold for roofing contractors?
Michigan requires workers’ compensation when you have three or more employees — OR when any single employee works 35 or more hours per week. This dual threshold means a solo full-time roofing employee triggers the WC requirement immediately, even if you technically have only one worker. Track employee hours carefully and obtain WC as soon as either threshold is met.
Do I need separate licenses for residential and commercial roofing in Michigan?
Yes. Michigan has separate licensing tracks. Residential roofing falls under the Residential Builder or Residential Maintenance and Alteration Contractor license through LARA. Commercial roofing requires a separate Contractor license. Verify which license type applies to the work you perform and hold both if your business does both residential and commercial roofing.
What is Michigan’s mechanic’s lien law and how does it affect my business?
Michigan’s Construction Lien Act (MCL 570.1101 et seq.) gives contractors and subcontractors the right to file a lien against a property for unpaid work. To protect lien rights, Michigan requires contractors to provide a Notice of Furnishing to the property owner. Failure to provide proper notice can void your lien rights. Conversely, filing an improper lien carries penalties. Understanding Michigan lien law — or working with an attorney who does — protects your ability to collect payment.
