Roofing general liability

General liability insurance for California roofing contractors

What roofing GL covers, the exclusions that get roofing claims denied, and what general contractors require on your certificate.

Last reviewed October 2026 · Robert Mathis, CA Lic. #4301600

General liability

General liability (GL) pays for bodily injury and property damage to other people caused by your operations. For roofers the common claims are water damage to the interior after a tear-off is left open, fire from torch-down or hot-mop work, materials falling from the roof, and damage discovered after the job is finished.

Typical limits
$1,000,000 per occurrence / $2,000,000 aggregate
Rated on
Usually gross receipts (annual revenue), plus type of roofing and residential vs. commercial mix. See price examples
Who asks for it
General contractors, property managers, HOAs, commercial owners and many homeowners
Required by CSLB
Only for LLC licenses ($1M–$5M)

Completed operations is the part of GL that responds after the job is done. Roof leaks often show up months later, so make sure your policy includes completed operations and that it isn't limited or excluded for roofing.

GL exclusions to check on a roofing policy

Two quotes at similar prices can cover very different things. Read for these before you compare price:

  • Open roof exclusion or warranty. Removes coverage for rain damage while a roof is torn off, or only covers it if you follow strict rules: limits on how much roof can be open at once, tarping by end of day, and no tear-off when rain is forecast. Water intrusion is the most common roofing GL claim, so read this one first.
  • Hot work / torch exclusion. Removes coverage for torch-down, hot tar or open flame. If you do any of that work, this exclusion matters most.
  • Height or story limits. Some policies only cover work up to two or three stories.
  • Residential, tract or new construction exclusions. Common in California. Some exclude all new residential; others exclude tract homes or condos.
  • Prior work exclusion. Excludes jobs completed before the policy started. A problem if you're switching carriers.
  • Subcontractor requirements. Many policies require your subs to carry their own GL with you as additional insured, or the claim isn't covered.
  • Action-over exclusion. Excludes claims where your own injured worker sues the GC and the GC passes it to you.
  • Classification limitation. Covers only the operations listed on the policy. Make sure every type of roofing you do is listed.

Blanket waiver of subrogation

After your carrier pays a claim, it normally has the right to recover the money from whoever caused the loss. That's subrogation. A waiver of subrogation gives up that right against a specific party, usually the general contractor or property owner you work for. Most commercial contracts require it.

Specific waiver
Names one party. Needs a new endorsement each time a contract requires it.
Blanket waiver
Applies automatically to anyone you've agreed in a written contract to waive. Better for roofers who work for many GCs.
Where it's needed
GL (form CG 24 04 or equivalent), commercial auto, and workers' comp (California form WC 04 03 06)
Cost
GL waivers are often free or a flat fee. Workers' comp waivers usually add a percentage of premium, and a blanket waiver costs more than a specific one.

Signing a contract with a waiver you don't have can leave you personally responsible for the GC's loss. Send us the contract before you sign.
