If you operate a roofing business, you need a layered insurance program that protects against the unique hazards your crews face every day. At a minimum, most states and general contractors require four core coverages: commercial general liability (CGL), workers' compensation, commercial auto, and an umbrella or excess liability policy. Depending on the size and scope of your operation, you may also need inland marine coverage for tools and equipment, builder's risk for projects under construction, and professional liability if you offer design-build services.
Commercial general liability is the foundation of your program. A standard CGL policy for a roofing contractor typically starts at $1,000,000 per occurrence and $2,000,000 general aggregate. This covers third-party bodily injury and property damage claims that arise from your operations, including damage caused by falling debris, misplaced materials, or foot traffic on a client's property. It also includes products-completed operations coverage, which protects you after you leave the job site if a roof you installed fails and causes interior water damage months or years later.
Workers' compensation is mandatory in nearly every state once you have employees. Roofing carries one of the highest workers' comp class codes in the NCCI system, typically class code 5551 for roofing with all types of materials. Rates vary by state but commonly fall between $10 and $30 per $100 of payroll, making it one of the most expensive line items in your insurance budget. OSHA consistently ranks roofing among the most dangerous occupations, with falls accounting for roughly one-third of all construction fatalities each year. A strong safety program and a clean experience modification rate (EMR) are the most effective ways to bring these premiums down over time.
Commercial auto insurance covers vehicles you own or lease for business use, including trucks, trailers, and equipment haulers. If your crews drive personal vehicles to job sites, you should also carry hired and non-owned auto coverage, which fills the gap when an employee causes an accident in a vehicle not titled to your company. Minimum liability limits of $1,000,000 combined single limit are standard for most roofing operations, though general contractors frequently require higher limits.
An umbrella or excess liability policy sits on top of your CGL, auto, and employers' liability limits and provides additional coverage, usually in $1,000,000 increments. Many commercial and government contracts require roofing contractors to carry $5,000,000 or more in total liability limits, which makes an umbrella essential for winning larger bids. The cost is relatively modest compared to the underlying policies because the umbrella only responds after those primary limits are exhausted.
Inland marine insurance covers tools, equipment, and materials in transit or stored at job sites. A standard commercial property policy only covers items at your listed business location, so if a trailer full of shingles is stolen from a job site overnight, inland marine is the policy that pays. Coverage limits typically range from $25,000 to $500,000 depending on your inventory.
Beyond these core coverages, you should evaluate whether you need builder's risk insurance for new construction projects, professional liability for design work, pollution liability if you handle asbestos abatement or work with spray-applied coatings, and surety bonds required by state licensing boards. The right insurance program balances adequate protection with manageable premiums, and working with a broker who specializes in construction risks is the fastest way to get there.
