Roofing insurance and bonding: what you actually need and what it costs

Insurance is the least exciting line on your budget until the day a tear-off leaks into a finished attic, a bundle slides off the edge onto a customer’s car, or a crew member goes off a two-story eave. Then it’s the only thing standing between a bad day and a closed business. And here’s the part every roofer needs to hear up front: roofing is one of the highest-risk classes insurers write. Height, falls, torches and hot work, tear-off debris, and water intrusion put you in a rating bucket most other trades never touch. That means your premiums run high, higher than an HVAC or plumbing shop of the same size, and it means the coverage gaps that catch roofers are specific and expensive. This is what you actually need, roughly what it costs, and where roofers get burned.

Why roofing pays more than any other trade

Two numbers drive your whole program, and roofing is at the top of both:

• Falls are the single largest cause of construction deaths, and roofing is the most exposed trade on that list. Underwriters know it. That pushes both your general liability and, especially, your workers’ comp rates to the high end of every published range.
• Water and “the roof failed” claims are frequent and costly. A roof that leaks doesn’t just cost the shingles; it can mean drywall, insulation, flooring, and mold remediation across multiple rooms.

So when you get a quote that looks steep, it isn’t your broker gouging you. Roofing simply runs high. Get multiple quotes and compare apples to apples, but don’t expect trade-average pricing. Anyone quoting you rock-bottom is probably misclassifying your work, which blows up at audit (see below).

The coverages that matter

• General Liability (GL), third-party bodily injury and property damage: your debris damages a car, a dropped tool hurts a bystander, a tear-off exposes an interior to a rain event. This is the baseline everyone needs and what clients ask to see. Because roofing is a high-hazard class, roofing GL costs meaningfully more than most trades. Treat any single figure you see online with suspicion and get real quotes. Make sure it includes completed-operations coverage: on a re-roof, the claim (a leak) often shows up after you’ve left, and completed-ops is what responds. And read the exclusions, see the faulty-workmanship trap below, which is the roofing coverage issue.
• Workers’ Compensation: covers employee injury (medical + lost wages), and it’s legally required almost everywhere once you have employees. Roofing carries among the highest workers’ comp rates of any trade: the rate is quoted per $100 of payroll, and the roofing classification is one of the priciest on the sheet precisely because of fall exposure. Payroll, job classification, state, and your claims history drive it. This is almost always your single largest insurance cost, and the one your safety record moves the most.
• Commercial Auto: your trucks, dumps, and their liability; personal auto policies exclude business use, so this is not optional. If you tow a dump trailer or run a boom/conveyor, tell your agent. It changes the rating.
• Tools & Equipment (inland marine / contractor’s equipment floater). Here’s a gap that bites: commercial auto usually does not cover the tools, ladders, nailers, and equipment inside a stolen or burned truck. A floater does. If a trailer full of gear can disappear overnight, you need this, and roofing gear plus a trailer adds up fast.
• Umbrella / Excess Liability: cheap extra limits stacked on top of GL and auto. When a commercial client, a GC, or a serious injury claim demands $2M-$5M in coverage, an umbrella is how you get there affordably. Given roofing’s injury exposure, this is not a luxury. A single fall claim can blow through a $1M primary limit.
• Business Owner’s Policy (BOP): bundles GL with commercial property (your shop, inventory, materials on hand) at a discount. Usually the efficient way to buy GL + property together for a small roofing shop.
• Professional Liability (E&O): worth considering if you do design or spec work (commercial flat-roof systems, engineered assemblies), where a design error, not a workmanship defect, causes a loss.

The faulty-workmanship trap: the roofing coverage issue

This is the one that catches roofers more than any other. Standard GL generally does not pay to redo your own defective work: the “your work” / faulty-workmanship exclusion. If you install a roof wrong and it leaks, GL typically covers the resulting damage to other property (the ruined ceiling and floors below) but not the cost of tearing off and reinstalling the roof you botched. Fixing your own workmanship comes out of your pocket. That’s a warranty/callback cost, not an insured loss.

Two practical consequences:

• Don’t assume “I have GL” means “a bad install is covered.” It usually isn’t, for the roof itself. Read the exclusions with your agent and know exactly where the line sits between your-work (excluded) and resulting-damage (often covered).
• Price and reserve for callbacks anyway. Because the redo isn’t insured, your workmanship warranty is a real liability you carry yourself. Build it into pricing and know your callback rate. (See know your numbers.)

Height and fall exposure: the thing underwriters price on

Falls are why your rates are what they are, so this is also where you have the most leverage. A documented safety program (fall-protection [harnesses, anchors, guardrails], ladder and hot-work protocols, training records, toolbox talks) does three things: it keeps people alive, it keeps regulators (OSHA in the US, provincial OHS in Canada) off your back, and it directly lowers your workers’ comp cost over time through your experience-mod. Roofing is the trade where “run a real safety program” is not a compliance checkbox; it’s the highest-ROI cost control you have. Insurers may ask about your fall-protection plan before they’ll even quote.

Subcontractor COI management: where a “cheap” crew gets expensive

Many roofing shops run subcontracted installers. If you do, an uninsured sub’s injury or damage claim lands on your policy, and worse, on your workers’ comp audit as if they were your payroll. Manage it like a system, not a favor:

• Collect a Certificate of Insurance (COI) from every sub before they set foot on a roof: proof of their own GL and their own workers’ comp, not just a signed agreement.
• Track expiration dates. An expired COI is the same as no COI at audit time. If a sub’s coverage lapsed mid-year, your auditor can add their payroll to your workers’ comp bill, a nasty surprise that can run into real money.
• Get named as additional insured on the sub’s GL where it matters, and confirm the endorsement wording actually responds. A mismatched additional-insured endorsement can leave you uncovered even when the COI looks fine.

The flip side: you’ll be asked for COIs constantly too. On commercial, property-managed, and GC work, no COI means no job, and GCs routinely require you to name them as additional insured. Be able to produce a COI same-day and keep renewals current. An expired certificate stalls work you already sold. (Same discipline you use hiring and running crews, see hiring and running crews.)

License, permit, and surety bonds (not the same as insurance)

Many states and municipalities require a contractor license bond to hold your roofing license, and jobs often require permit bonds. A bond isn’t insurance for you. It guarantees your compliance to the public, and if a claim is paid, you repay the surety. Mechanics:

• Bond amount is set by the jurisdiction, commonly in the four- to five-figure range, though some states scale it to revenue or license class. Check your own board; roofing-specific bonding requirements vary widely.
• You pay a premium, not the full face amount: a small percentage of the bond’s value per year, cheaper with strong personal credit and more expensive with weak credit. A modest license bond is usually a minor annual cost, not a major line item.
• Confirm the exact requirement with your state/city licensing board. This is covered in detail in the roofing licensing & certification guide.

🇨🇦 Canada notes

• Workers’ compensation is a provincial board, and it’s mandatory: WSIB in Ontario, WorkSafeBC in BC, WCB in Alberta and most provinces. In construction it typically covers even sole proprietors and independent operators with no employees, not just companies with staff. Roofing is a high-rate classification with the board just as it is in the US. Register and keep your account in good standing.
• The subcontractor trap is even sharper here: hire a sub without their own WSIB/WCB coverage and you can be on the hook for their premiums and their injuries. Always pull a clearance certificate before a sub works, and re-pull it, because it expires.
• $2M general liability is the practical norm, and many municipalities require proof of $2M GL + a WSIB/WCB clearance certificate to issue or renew your contractor business licence.
• WSIB/WCB ≠ employers’ liability. The board covers the worker’s comp claim; a separate employer’s liability layer fills gaps. Carry both.

Checklist

• General liability in force; $2M limit if you touch commercial/property-managed work, and know exactly what the faulty-workmanship exclusion does and doesn’t cover.
• Workers’ comp (US) / register WSIB/WorkSafe/WCB (Canada), mandatory with employees, often for solo operators in Canadian construction, and your biggest cost as a roofer.
• Commercial auto on every truck and trailer (personal auto excludes business use).
• Tools & equipment floater: don’t assume commercial auto covers the gear in the truck/trailer.
• Umbrella for extra limits, a fall claim can exhaust a $1M primary.
• Get the license/permit/surety bond your state/city requires.
• Collect and track a COI (GL + workers’ comp) from every sub, watch expiration dates, and get named additional insured where it matters.
• Be able to produce your own COI same-day; add clients as additional insured when required; keep renewals current.
• Canada: pull a WSIB/WCB clearance certificate from every sub and carry employer’s liability alongside the board.
• Run a documented fall-protection and safety program: it’s the biggest lever on your workers’ comp cost.
• Use an independent trades-savvy agent, classify payroll accurately, and review annually as you grow.

The bottom line

Roofing is expensive to insure because it’s genuinely dangerous and genuinely leak-prone, so accept that your program costs more than the neighboring trades, get multiple quotes, and don’t let anyone win your business by misclassifying your work. Get the baseline right (GL, workers’ comp/WSIB, commercial auto), then close the roofing-specific gaps: understand that GL won’t pay to redo your own bad install, insure the tools in the truck, and manage subcontractor COIs like a system so an uninsured sub doesn’t land on your policy and your audit. Buy your required bond, keep a COI ready so it never costs you a job, and run a real fall-protection program, because in roofing, your safety record is also your cheapest insurance discount.
