A minimum premium is the lowest amount an insurance carrier will charge for a policy regardless of your actual exposures. Even if your payroll, revenue, or other rating basis falls below the level that would generate the minimum premium through normal calculation, you still pay the minimum. For roofing contractors, minimum premiums are particularly relevant because carriers set higher minimums for high-hazard classifications like roofing to ensure the premium collected justifies the risk they are assuming.
Workers compensation minimum premiums for roofing contractors typically range from $5,000 to $15,000 depending on the state and carrier. General liability minimums for roofing operations are often $7,500 to $20,000. These minimums mean that even a one-person roofing operation with minimal payroll will pay a baseline premium that reflects the inherent danger of the work rather than the small size of the operation.
Understanding minimum premiums is important when you are starting a new roofing business or scaling back operations. If your estimated annual payroll would generate a premium of $3,000 through the normal rate calculation but the carrier's minimum premium is $10,000, you will pay $10,000. This affects your cash flow planning and overhead calculations. When shopping for insurance, compare minimum premiums across carriers because they vary significantly. Some carriers specialize in smaller roofing operations and offer lower minimums, while others focus on larger contractors and set minimums that are prohibitive for startups. Your broker should match you with a carrier whose minimum premium structure fits your business size.
