General liability insurance for contractors typically runs $204 to $596 per month, but the average hides a wide spread driven mainly by trade, not company size. Roofing carries the highest rate of any common trade at $45 to $65 per $1,000 of revenue, reflecting the frequency and severity of fall claims, while painting and finishing work runs as low as $12 to $18 per $1,000. Workers compensation adds another real cost, commonly $80 to $340 or more per worker per month depending on state and job classification. Knowing where your trade sits on this spread before shopping for coverage prevents sticker shock and helps you spot a quote that is genuinely out of line.
Key takeaways
- General liability insurance for contractors commonly runs $204 to $596 per month, though the full range spans from roughly $25 to well over several thousand depending on trade, revenue and claims history.
- Roofing carries the highest general liability rate of any common trade at $45 to $65 per $1,000 of revenue, due to the frequency and cost of fall-related claims.
- Electrical work runs $18 to $25 per $1,000 of revenue, plumbing and mechanical $15 to $22, general contracting $20 to $30, and painting or finishing work as low as $12 to $18.
- Workers compensation costs vary enormously by state, from roughly $39 per employee per month in Indiana up to $459 in New York for general contractors, according to industry benchmark reporting.
- Carriers price primarily by trade classification and claims history, not revenue alone, meaning the type of work you do matters more to your premium than how big your company is.
What drives the cost more than anything else
Insurance carriers set rates using historical claims data by trade classification code, and the gap between trades reflects real, measurable claim frequency and severity differences, not arbitrary pricing. A roofer working at height generates more claims, and more expensive claims, than a painter working mostly at ground level, and the premium reflects that gap directly. This is the single most important thing to understand before requesting quotes: your trade classification, not your revenue or your years in business, is the dominant factor in what you will pay.
General liability rates by trade
| Trade | Rate per $1,000 of revenue | Why |
|---|
| Roofing | $45 to $65 | Highest fall risk, frequent and severe claims |
| Concrete and masonry | $25 to $35 | Heavy equipment and material handling risk |
| General contracting | $20 to $30 | Broad exposure across subcontracted trades |
| Electrical | $18 to $25 | Fire and shock risk, moderate claim severity |
| Plumbing and mechanical | $15 to $22 | Water damage exposure, moderate frequency |
| Painting and finishing | $12 to $18 | Lower physical risk profile than structural trades |
These figures are rate per $1,000 of revenue, so a roofer doing $500,000 in annual revenue at the midpoint $55 rate would pay roughly $27,500 a year in general liability premium, while a painter at the same revenue at a $15 rate would pay closer to $7,500. That is close to a four-fold difference for the same revenue, purely from trade classification.
Workers compensation: the other major cost, and it varies by state
Workers compensation premiums vary more by state than by trade in many cases, since each state sets its own base rates and rules. Industry benchmark reporting puts average workers comp costs for general contractors from roughly $39 per employee per month in Indiana up to $459 in New York, an enormous spread driven by state-level regulatory and claims cost differences rather than anything a contractor controls directly. Separately, workers comp rates are commonly quoted per $100 of payroll, ranging roughly $2.46 to over $13 depending on state and job classification code, which translates to roughly $80 to $340 or more per worker per month in practice.
If your business operates in a high-cost state like New York, shopping multiple carriers and asking specifically about classification code accuracy matters more than it would in a lower-cost state, since a misclassified employee can meaningfully inflate the premium.
What actually moves your premium besides trade
- Claims history: a clean claims record over several years is the single biggest factor within your control, and carriers reward it with meaningfully lower renewal rates.
- Revenue: higher revenue means a higher premium since exposure scales with the volume of work performed, but revenue is a secondary factor behind trade classification.
- Years in business: newer businesses sometimes pay a premium for lack of track record, though this factor carries less weight than trade and claims history.
- Coverage limits: higher liability limits cost more, and the right limit depends on the size of contract you typically bid, since many commercial clients require a minimum limit to award work.
- Subcontractor use: using uninsured or underinsured subcontractors can expose a general contractor to claims that should have been covered by the sub's own policy, which carriers price into the overall risk.
How to shop for coverage without overpaying
Get at least three quotes from carriers or brokers who specialize in contractor and construction insurance specifically, since a general small-business insurance agent may not accurately classify your trade or understand the coverage nuances that matter for construction risk. Confirm your exact trade classification code on each quote, since a misclassification, even an honest one, can either overcharge you or leave you underinsured for your actual work. Ask directly what claims history and safety programs would reduce your premium at renewal, since carriers often have documented discount criteria that are not automatically applied unless you ask.
Bundling general liability with workers compensation and commercial auto through the same carrier frequently reduces total cost compared to separate policies, worth asking about directly even if you started the search assuming you needed separate coverage for each.
Proof of insurance is a genuine competitive advantage with commercial clients and increasingly with residential homeowners who have become more insurance-conscious after widely publicized contractor fraud cases, the same shift in buyer behavior covered in Yelp, Houzz, BBB and Angi: should contractors pay in 2026. Carrying adequate coverage and being able to produce a certificate of insurance quickly during a sales conversation closes deals that an uninsured or underinsured competitor loses before the conversation even gets to price. Treating the premium as pure overhead misses this half of the value.

How we put this together
Rate ranges by trade and workers compensation figures in this article are drawn from multiple independent industry benchmark sources reporting consistent ranges as of 2026, since insurance pricing varies by carrier, state and individual risk factors in ways no single public source fully captures. We did not obtain our own quotes to verify these figures directly, and actual premiums for your specific business will depend on your state, claims history and coverage limits, so treat these as directional benchmarks for budgeting rather than a quote for your business.
Frequently asked questions
How much does general liability insurance cost for a contractor?
Most contractors pay between $204 and $596 per month for general liability insurance, though the actual rate depends heavily on trade classification, with roofing paying roughly $45 to $65 per $1,000 of revenue and painting as low as $12 to $18 per $1,000.
Why does roofing insurance cost so much more than other trades?
Roofing carries the highest general liability rate of any common trade because working at height generates more frequent and more severe insurance claims than most other construction work, and carriers price directly based on that historical claims data.
How much does workers compensation cost per employee?
Workers compensation commonly runs $80 to $340 or more per worker per month, though this varies enormously by state, from roughly $39 per employee monthly in Indiana up to $459 in New York for general contractors, according to industry benchmark reporting.
Does insurance cost more as my company grows?
Yes, since premium scales with revenue and payroll, but trade classification and claims history remain bigger factors in your rate than company size alone. A small roofing company can pay more than a larger painting company at the same revenue.
What is the best way to lower my contractor insurance premium?
Maintaining a clean claims history over time is the single biggest factor within your control, alongside shopping multiple contractor-specialized carriers, confirming accurate trade classification, and asking directly about bundling discounts across general liability, workers comp and commercial auto.
Do I need insurance to bid on commercial jobs?
Most commercial clients require proof of insurance meeting specific coverage limits before awarding work, and being able to produce a certificate of insurance quickly is a genuine competitive advantage over uninsured or underinsured competitors.
