You ran a clean year — zero claims, strong safety record, no audit adjustments — and your renewal still came in 12% to 25% higher. It feels unfair, and you are not alone. Roofing contractors across the country are seeing premium increases that have nothing to do with their individual performance. Understanding the forces behind these increases helps you push back effectively and make smarter decisions about your insurance program.
Catastrophe Losses and Reinsurance Costs
Insurance carriers purchase their own insurance, called reinsurance, to protect against catastrophic losses. When hurricane seasons produce $50 billion to $100 billion in insured losses (as they have in recent years), reinsurance costs spike — and carriers pass those increases to policyholders. Roofing contractors are disproportionately affected because your industry is directly tied to weather-related claims. Even if your company is in a low-CAT state, your carrier's overall book of roofing business includes coastal and hail-belt exposures that drive their reinsurance costs up globally.
The 2023-2025 reinsurance market saw rate increases of 20% to 40% for property catastrophe treaties. Your carrier absorbed some of that, but a meaningful portion flows through to your renewal.
Industry Loss Ratios
Carriers evaluate profitability by class code. If NCCI class code 5551 (roofing) produces a loss ratio above 65% to 70% across the carrier's book, they raise rates for all roofing accounts — regardless of individual performance. Roofing consistently runs loss ratios between 60% and 85% depending on the year, making it one of the least profitable classes for insurers. When a carrier loses money insuring roofers as a class, every roofer's premium goes up.
Social Inflation and Litigation Trends
The average cost to settle a construction defect lawsuit has increased roughly 8% to 12% annually over the past five years. Nuclear verdicts — jury awards exceeding $10 million — in construction cases have become more common. Plaintiff attorneys are increasingly targeting roofing contractors in habitability and construction defect suits, particularly in states like Florida, Texas, and Colorado. Carriers respond by increasing rates across their entire roofing book to account for rising claim severity.
Material and Labor Cost Inflation
When claims are paid, they are paid at current replacement costs, not the costs in effect when the policy was written. Roofing material costs have increased 30% to 60% since 2020, and labor costs are up 15% to 25%. A completed operations claim on a roof installed in 2022 that fails in 2025 costs significantly more to repair at 2025 material and labor prices. Carriers must price for this inflation in their rate calculations.
Capacity Contraction
Several standard market carriers have pulled back from insuring roofing contractors entirely in recent years, reducing the number of available markets. When fewer carriers compete for your business, pricing power shifts to the insurers. If your current carrier knows there are only two or three alternatives that will quote your account, they have less incentive to offer competitive renewals. This capacity contraction is especially acute for roofing contractors with revenue above $3 million, hot-work operations, or coastal exposure.
What You Can Do About It
Market your account early. Start the renewal process 90 to 120 days before expiration. Give your broker time to approach multiple carriers and create competitive tension.
Provide a compelling submission. Carriers offer their best rates to accounts that demonstrate professionalism. A current loss run, safety manual, OSHA 300 logs, fleet MVR reports, and a detailed description of your operations separate you from the contractors who provide a one-page application. Include your EMR history showing a downward trend, crew certifications, and project references.
Adjust your program structure. Increasing your deductible from $1,000 to $5,000 can reduce your GL premium by 8% to 15%. Bundling GL, auto, and inland marine with a single carrier often produces package discounts of 10% to 15%. Consider a higher SIR on workers comp if your cash flow supports it.
Challenge the renewal. Ask your broker to provide a written justification for every rate increase. If the carrier cites "market conditions" without specifics, push for detail. Request a breakdown of loss-driven vs. rate-driven increases and benchmark your renewal against industry averages for your class code and revenue size.
Premium increases without claims are frustrating, but they are not arbitrary. Understanding the drivers puts you in a stronger position to negotiate and make informed decisions about your coverage.
