Can I sue a roofer for a leaking roof?
Yes. Roofers carry workmanship warranties and the manufacturer warranties stack on top. A new roof that leaks within the workmanship warranty period (typically 2 to 10 years) is a clear case. The roofer is responsible for the cost to fix the leak and any interior damage. The shingle manufacturer's warranty (often 25 to 50 years) provides additional protection for material failures. Roofing is heavily licensed in most states, so the contractor licensing board and the bond claim are reliable pressure points.
What roofer failures let you sue?
Four common patterns. Most leaking-roof cases involve workmanship rather than material defects, and workmanship is the contractor's responsibility regardless of material warranties.
Improper flashing
The most common cause of new-roof leaks. Flashing around chimneys, vents, walls, valleys, and skylights has to be installed per manufacturer specs. Skipped step flashing, missing kick-out flashing, or wrong-pitch valley flashing causes leaks within months.
Underlayment shortcuts
Synthetic underlayment under shingles is required by most building codes and manufacturer specs. Skipping it, using felt where synthetic is required, or improper overlap causes leaks during heavy rain.
Nailing pattern violations
Each shingle requires 4 to 6 nails per manufacturer specs. Wrong nail placement (too high, too low, too few) creates wind-uplift failures. Over-nailing creates sealant failures. Both void the manufacturer warranty.
Damage to interior from leaks
Interior ceilings, walls, attic insulation, hardwood floors, and electrical components damaged by water from a defective roof. The roofer is responsible for foreseeable interior damage caused by their workmanship.
How much can you recover?
Roof repair is the floor. Interior damage from leaks stacks on top. The cost to fully redo a defectively-installed roof can hit small-claims caps quickly.
Roof repair or partial redo
Cost to install proper flashing, fix underlayment, redo affected shingle areas, or in severe cases redo the entire roof. Quote from a different licensed roofer.
Interior damage repair
Drywall, paint, insulation, hardwood floors, electrical components damaged by leaks. Restoration company quote covers all interior items.
Filing fees, expert reports, interest
Filing fee, paid second-opinion report ($200 to $500), pre-judgment interest at your state's legal rate.
Cost to install proper flashing and redo affected shingle areas, plus interior damage from leaks, plus filing fee.
Send a demand letter first.
Roofer demand letters work especially well when paired with a second-opinion report identifying the workmanship defect. The roofer knows they cannot beat a written report from a licensed peer.
- Date of installation and date leaking started
- The workmanship defect identified by a second-opinion roofer
- Photos of the defect and the resulting damage
- Quote from a replacement roofer for the fix
- Restoration quote for interior damage
- A 14-day deadline before you file
- Sent certified mail with copy to the GL carrier
On September 8, 2025, you installed a new asphalt-shingle roof for $14,200. The roof began leaking on October 22, 2025 (less than 7 weeks later). I obtained a second-opinion report from Apex Roofing (license #2218) identifying step flashing missing at the chimney and improper overlap of valley flashing as the cause.
Apex's quote to install proper flashing and redo affected shingle areas: $4,800. American Restoration's quote for interior damage repair (drywall, paint, insulation): $3,500. I demand within fourteen (14) days:
- Reimbursement of $4,800 for proper flashing and redo;
- Reimbursement of $3,500 for interior-damage repair.
Total demand: $8,300.00. Copy of this letter has been sent to your GL carrier (West Casualty, policy GL-2025-9821) and the North Carolina Licensing Board for General Contractors. If unresolved, I will file in Small Claims Court.
How to file a roofer-leak case.
Four steps. The second-opinion report is the spine. Insurance and board complaints run in parallel.
Get a second-opinion roofer report
Hire a licensed roofer (different from the one who installed) for a paid inspection. Get a written report with photos, defect descriptions, and a cost-to-fix quote. Expect to pay $200 to $500 for thorough work.
File with GL carrier and contractor board
Roofers carry GL insurance for damage their work causes. File a third-party claim. State boards investigate roofing complaints because of the public-safety implications of leaks. Both run free.
File in small claims
If insurance and board do not resolve within 60 days, file. Filing fees usually run $30 to $100. File in the county where the roof is located.
Hearing
Lead with the second-opinion report and the photos of the defect. Show the timeline of installation and the start of leaks. Hearings usually run 10 to 15 minutes.
Collecting and bond claims.
Roofers carry licensing bonds and GL insurance. Bond claims pay out before other creditors. After 30 days post-judgment, the enforcement tools are a judgment lien on real estate, a bank levy, and a writ of execution on tools or vehicles. Roofing-board complaints can also block license renewal.
What evidence do you need to sue a roofer?
Cases like this turn on the second-opinion report and the timeline. Photos of the defect plus interior damage show the chain.
Inspected the roof installed September 8, 2025. Defects observed: step flashing absent at chimney left side; valley flashing has 2-inch overlap (manufacturer spec requires 6 inches); shingle nailing pattern shows over-driven nails on south slope.
Cost to install proper flashing, redo south slope, and add manufacturer-spec valley flashing: $4,800. Estimated 4 working days.
Valley Flashing Overlap
Valley flashing must extend a minimum of 12 inches up each side from the valley centerline. Adjacent flashing pieces must overlap by no less than 6 inches with sealant between layers.
Inspection found 2-inch overlap. Manufacturer warranty void on valley work as installed.
Common roofer defenses, with rebuttals.
Three arguments cover most leaking-roof cases. Each has a clean rebuttal once the second-opinion report is in evidence.
Keep it simple. Organized records, clear timelines, and solid evidence are your best defense.
How much do homeowners actually win?
Typical recovery in leaking-roof cases. The second-opinion report drives the result.
Partial flashing redo. Court awards the cost to fix the specific defect. Common when the leak is contained and interior damage is minimal.
Repair plus interior damage. Most common when the second-opinion report is clear and the interior damage is documented.
Cap-of-the-court awards. Major flashing failures requiring partial roof redo, plus significant interior damage. Multiple-room damage cases push to the cap.
Better evidence. Better prep. Better outcome. Your documentation makes the difference.
What are the alternatives to small claims?
Roofing has unusually strong out-of-court options because roofers are heavily licensed and insured.
Roofer's GL insurance
Free, fast, biggest payerWhen it fits: interior damage from the leaks. The roofer's GL covers exactly this. File a third-party claim with the carrier using the certificate of insurance.
Tradeoff: the carrier may dispute coverage scope (workmanship vs. damage). The second-opinion report establishes the link.
State contractor or roofing board
Free, regulatoryWhen it fits: the roofer is licensed (most are). Boards investigate roofing complaints aggressively. Florida has a specific roofing license. CSLB roofing classification (C-39) in California.
Tradeoff: the board can pull the license but does not always order restitution.
Small claims (this guide)
When the others failWhen it fits: the carrier and board did not resolve within 60 days. Damages within your state's cap.
Tradeoff: 30 to 90 day timeline. Filing fee $30 to $100.
Recover the repair cost.

How long is a roofer's workmanship warranty?
Typically 2 to 10 years for asphalt-shingle roofs, 10 to 25 years for metal or tile. The warranty is in writing and should be part of your contract. Even if the written warranty is shorter, the implied warranty of workmanlike construction in most states extends the protection.
What is the difference between workmanship warranty and manufacturer warranty?
Workmanship is the roofer's responsibility for proper installation. Manufacturer is the shingle company's responsibility for material defects. Workmanship covers most leak causes (flashing, nailing, underlayment). Manufacturer covers material failures (premature shingle aging, blistering, granule loss).
Can I claim against the manufacturer warranty?
Sometimes. Manufacturer warranties cover material defects but usually require proper installation. Improper installation often voids the manufacturer warranty. The second-opinion report tells you whether the failure is workmanship (the roofer is responsible) or material (the manufacturer is). Most are workmanship.
What if the roofer is out of business?
Two paths still work: bond claim and GL insurance claim. Both pay even if the company shut down. The bond and the policy were active when the work was done; the obligation to pay survives the company's closure. Both should be on the certificate of insurance.
How do I find a roofer's license and bond?
Search your state's contractor licensing board website. California: cslb.ca.gov, search for license type C-39. Florida: myfloridalicense.com. The license record shows the bond amount, the surety, current status, and any past complaints.
How long do I have to sue?
Breach of contract and warranty claims usually run 3 to 6 years from the date of installation. Latent defects (problems that develop later) often have a discovery clock that starts when the leak appeared. Some states have construction-specific statutes of repose capping the window at 8 to 12 years from completion.
Will my homeowners insurance cover this?
Sometimes for the interior damage, never for the cost to redo the roof. Use your homeowners insurance only when you need fast repair. Your carrier will pay you and pursue the roofer (subrogation), but you eat the deductible and the claim may affect your premium.
