What is a waiver of subrogation? (Plain English, 2026)
If a contractor asks for a 'waiver of subrogation' in their contract, they're asking your insurance company to give up its right to come after them after a covered claim. Here's exactly what that means, why it's standard for some kinds of work, and the times you should hesitate before agreeing.
The short answer
- Subrogation is your insurance company's right to step into your shoes and sue whoever caused a loss they paid you for.
- A waiver of subrogation removes that right — typically requested by a contractor as part of their contract with you.
- It's standard in commercial construction and lease agreements; it's less common in residential roofing but does come up.
- Agreeing to a waiver isn't usually catastrophic, but understand what you're giving up before you sign — your insurer may charge a higher premium or deny coverage if they discover an undisclosed waiver after a claim.
Subrogation, in one paragraph
Subrogation is the legal principle that lets your insurance company step into your shoes after they pay you for a loss. Imagine a roofer's worker falls through your skylight and damages your living room floor. You file a homeowner's claim, your insurer pays you $5,000 for the floor repair. Subrogation lets your insurer then turn around and sue the roofing company (or their CGL carrier) to recover that $5,000. It's a recovery mechanism that ultimately keeps your premiums down, because every successful subrogation claim is money the insurer doesn't have to pay out of the broader pool.
What a waiver of subrogation does
A waiver of subrogation is a contract clause where one party (typically you) agrees that your insurance company won't pursue subrogation against another party (typically the contractor). After a covered loss, your insurer pays you, and that's the end of it — no follow-up lawsuit against the contractor.
This sounds bad for you (and good for the contractor), but it's actually neutral in many cases because: (a) you're getting paid by your insurer either way, (b) subrogation lawsuits don't usually flow directly back to you, and (c) construction contracts often include mutual waivers — both parties agree neither side's insurer will subrogate against the other.
Why contractors ask: their CGL premiums go up if their carrier has to pay subrogation claims, and the legal cost of defending subrogation suits is real. A waiver up-front simplifies the risk picture for them.
When waivers are routine vs when to push back
**Routine in commercial construction.** AIA contract documents (the standard contracts for commercial building) include mutual waiver-of-subrogation provisions. If you're managing a commercial project, you'll almost certainly see and agree to one.
**Routine in commercial leases.** Landlord-tenant lease agreements commonly include mutual waivers — neither party's insurer can sue the other after a covered loss.
**Less common in residential roofing.** Most residential roof contracts don't include subrogation waivers. If a roofer asks for one, ask why. It's not necessarily bad, but it's worth understanding their reasoning.
**Push back when it's one-sided.** A waiver where you waive against the contractor but the contractor doesn't waive against you is asymmetric. Mutual waivers are reasonable; one-sided isn't.
**Push back when paired with an AOB.** A waiver of subrogation combined with an Assignment of Benefits is a red flag. The combination effectively transfers all your post-claim rights to the contractor: they collect proceeds, your insurer can't pursue them, and you have no leverage if work is shoddy.
Notify your insurer if you sign a waiver
Most homeowner's policies require you to notify your insurer if you sign a contract that affects subrogation rights. Read your policy's 'duties after loss' or 'cooperation' clause. If a covered loss happens later and your insurer discovers an undisclosed waiver, they may deny coverage or charge a higher premium retroactively.
The notification is usually as simple as forwarding the contract to your insurance agent and asking them to flag any concerns. Most agents will tell you whether the waiver is standard or whether it triggers a coverage adjustment.
Subrogation vs Assignment of Benefits — easy to confuse
**Subrogation:** your insurer's right to sue a third party who caused a loss they paid you for. A waiver gives up that right.
**Assignment of Benefits (AOB):** your right to negotiate insurance benefits, transferred to a contractor. They handle the claim instead of you.
These are different concepts. A subrogation waiver is generally lower-risk and often standard. An AOB is generally higher-risk and almost never appropriate for residential roofing. Don't confuse the two — and don't sign an AOB thinking it's a subrogation waiver.

Frequently asked
- If I sign a waiver of subrogation, am I giving up my right to sue the contractor?
- No. You retain your own right to sue the contractor for breach of contract, negligence, etc. The waiver only affects your insurer's right of recovery — not yours.
- Will my homeowner's insurance premium go up if I sign one?
- Sometimes. Some carriers charge a small premium adjustment for waiving subrogation; others don't care for residential. Ask your agent before signing.
- Can my insurer deny my claim if I signed a waiver?
- If the policy required notification of waivers and you didn't notify, possibly. If you disclosed the waiver and the carrier accepted it, no — the waiver doesn't change whether your loss is covered.
- Is a waiver of subrogation the same as 'additional insured' status?
- No. Additional insured status names another party as an insured under your policy. Subrogation waiver gives up your insurer's recovery right against another party. They're different mechanisms; some contracts include both.
- Should I refuse a waiver of subrogation in a residential roofing contract?
- Not necessarily. If it's a mutual waiver (both parties' insurers waive against each other), it's often fine. If it's one-sided, ask why. If it's paired with an AOB, walk away.
- What if a roofer says 'this is just standard, don't worry about it'?
- The line 'just standard' is itself a soft pressure tactic. Read the clause. If it really is standard mutual waiver language, agree. If it's something else, take the time to understand it. Reputable contractors will explain their contract; storm chasers won't.
