A standard roofing contract is the written agreement that locks in exactly what your roofer will do, what materials they’ll use, what you’ll pay, and when. Before you sign one, make sure it identifies a licensed and insured contractor, describes the work in brand-and-product detail, ties payments to milestones instead of dates, requires written change orders and lien waivers, states both the manufacturer and workmanship warranties in writing, and preserves your right to cancel if the deal was pitched at your door. Everything below is what each of those sections should actually say.
Who You Are Signing With
The top of the contract identifies both parties. For the contractor, that means the legal business name exactly as it appears on their state registration, a physical street address rather than a P.O. box, phone, email, and professional license number. The license number is what lets you verify standing through your state’s contractor licensing database before any work begins.
Then ask for a certificate of insurance. At a minimum it should show general liability coverage, which protects your property if the crew damages it, and workers’ compensation coverage, which keeps you from being personally liable if a roofer is injured on your roof. The certificate should name the insurer, policy numbers, coverage limits, and effective dates that span the entire project. A contractor who resists providing proof of insurance has told you what you need to know.
Scope of Work and Materials
Vague scope language is where contracts fail homeowners. Every physical action the crew will perform should be written out: is this a complete tear-off down to the deck or an overlay on top of the existing roof, how many layers are already up there, and what happens to the old material.
Then pin down the products by brand and line, not category. “Architectural shingles” is not specific. “GAF Timberline HDZ in Charcoal” is. The same precision applies to the underlayment (synthetic felt versus ice-and-water shield), the flashing material and thickness around chimneys, valleys, and vent pipes, the ridge vents or other ventilation components, and the drip edge along eaves and rakes. This level of detail blocks material substitution on the job and protects your warranty: most major manufacturers require specific installation methods and accessory pairings to honor coverage.1GAF. Warranty and Guarantee Resources CertainTeed ties extended warranty eligibility to credentialed contractor installation per manufacturer instructions.2CertainTeed. Understanding Roof Warranties
Who Pulls the Permit
Nearly every jurisdiction requires a building permit for a residential roof replacement. The contract should state clearly that the licensed contractor is responsible for pulling it. If a contractor asks you to pull the permit yourself, treat that as a signal they lack proper licensing or want to avoid code inspections.
List the permit fee as a separate line item in the cost breakdown. When the project wraps, the local building department inspects the work for code compliance, and the permit also creates a public record that matters when you sell the house or file an insurance claim. Roofing work done without a permit can trigger fines, forced removal of the new roof, or complications with your homeowner’s insurance.
Price and Payment Schedule
Payment is where you have the most leverage, and the schedule should be tied to verifiable milestones rather than calendar dates. A typical structure breaks into three parts: a deposit before work begins, a progress payment after tear-off and deck inspection, and a final payment on your walkthrough approval. Never pay the full amount upfront.
Many jurisdictions cap the deposit a contractor can collect. Limits vary; some states restrict it to ten percent of the contract price or a fixed dollar cap, whichever is less. Check your local consumer protection rules before agreeing to a large upfront payment.
Every cost component should appear as its own line item: labor, materials, permit fees, dumpster rental, and debris disposal. Lump-sum pricing with no breakdown makes it nearly impossible to evaluate a later change order fairly.
Include specific start and projected completion dates. If timely completion actually matters, because you’re coordinating with an insurance claim deadline or a home sale, consider adding a “time is of the essence” clause. Without that language, courts tend to treat construction deadlines as flexible and only require completion within a reasonable time. The clause turns the date into a firm obligation, and missing it becomes a material breach that lets you terminate or pursue damages. The contract should also set out, in writing, how delays outside the contractor’s control (extended rain, material backorders) extend the timeline.
Change Orders for Hidden Damage
Rotten decking, damaged rafters, and inadequate ventilation framing often hide under old shingles. Roughly one in three roofing jobs turns up some kind of surprise once the tear-off exposes the deck. If your contract doesn’t address how those discoveries get priced and approved, you’ll be negotiating with a contractor who already has your roof open.
Build in a change order procedure: the contractor stops the extra work, documents the problem with photos, provides a written cost estimate, and gets your written approval before proceeding. Even better is pre-setting unit prices for common extras in the original contract, like a per-sheet price for plywood deck replacement and an hourly rate for structural repairs. If the crew finds three sheets of rotted decking, you already know the cost and can approve on the spot.
Never accept a verbal change order. Even where oral modifications are technically enforceable, proving what was agreed to without a signed document is a fight you don’t want. A one-page change order describing the extra work, the cost, and the revised timeline, signed by both parties before the work starts, is all you need.
Both Warranties, in Writing
A roofing project involves two separate warranties, and the contract needs to address both. The manufacturer warranty covers defects in the materials. The workmanship warranty, from the contractor, covers installation errors. They are independent: a manufacturer won’t cover a leak caused by improper nailing, and a workmanship warranty won’t replace a shingle that delaminated from a factory defect.
Manufacturer coverage on many shingle lines runs 25 years or longer for material defects. Workmanship warranties are shorter. CertainTeed’s guidance notes that most contractors set their workmanship coverage at one to two years, though some offer longer.2CertainTeed. Understanding Roof Warranties Whatever the length, get it written into the contract itself, not promised in a document that will arrive later.
Read the exclusions. Workmanship warranties commonly exclude weather damage, unauthorized modifications by someone other than the original contractor, improper maintenance, and normal wear.2CertainTeed. Understanding Roof Warranties Those are standard. Watch instead for overly broad exclusions that effectively void coverage for any moisture issue or anything discovered more than 30 days after completion.
Lien Waivers at Every Payment
Here’s the scenario that catches homeowners: you pay the general contractor in full, but they never pay the shingle supplier or the subcontractor who did the flashing. Those unpaid parties can file a mechanics lien against your property. The lien can cloud your title, block a refinance or sale, and in the worst case force a foreclosure to satisfy the debt. You end up paying twice for the same work.
Lien waivers prevent this, and your contract should require them at every payment milestone. A conditional waiver is signed when payment is due but hasn’t cleared, and it only takes effect once the funds arrive. An unconditional waiver confirms payment has been received and gives up lien rights for that amount. Collect a conditional waiver from the contractor and from any subcontractors or major suppliers before releasing each progress payment, then follow up with unconditional waivers once checks clear. At final payment, collect unconditional final waivers from everyone who worked on or supplied materials for the roof.
The contract should name this process: who provides waivers, which type, and at what stage. A contractor unfamiliar with lien waivers, or one who resists including them, is a serious warning sign.
Cleanup and Property Protection
Roofing generates an enormous amount of debris: old shingles, felt paper, nails, flashing scraps, packaging. The contract should put cleanup and disposal on the contractor, including daily site maintenance on multi-day projects. A magnetic nail sweep of the yard, driveway, and surrounding areas is standard and worth requiring in writing. Stray roofing nails in a driveway are a guaranteed flat tire.
Property protection belongs in the same section: tarps over landscaping, plywood over air conditioning units, and precautions for siding and windows near the work area. If a dumpster is involved, state where it will sit and who is liable for driveway damage from the weight.
Dispute Resolution
The contract should spell out what happens when the two sides disagree. Mediation brings in a neutral third party to help reach a voluntary settlement; the mediator doesn’t decide anything, and statements made in mediation can’t be used later if it fails. Arbitration is a private trial: an arbitrator hears evidence and issues a binding decision that replaces your right to go to court.
Many homeowners sign mandatory binding arbitration clauses without realizing they’ve given up their right to sue or appeal. Read this section carefully. If arbitration is required, check who pays the arbitrator’s fees (which can run into thousands of dollars), which organization’s rules govern, and where arbitration takes place. If you want to keep the option of court, negotiate for a clause that requires mediation first and lets either side proceed to litigation if mediation fails.
Signing and Your Right to Cancel
Both the property owner and an authorized representative of the roofing company must sign and date the contract for it to be enforceable. Electronic signatures are valid for construction contracts under the federal E-SIGN Act, which provides that a contract cannot be denied legal effect solely because it was signed electronically.3Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity Digital or ink, initial any addendums or high-stakes clauses (arbitration, change order procedure) to confirm you reviewed them individually.
If the contractor came to your door or approached you at a temporary location, common after storms when crews canvass affected neighborhoods, you may have a right to cancel. The FTC’s Cooling-Off Rule under 16 C.F.R. Part 429 gives buyers three business days to cancel contracts for sales made at their home, workplace, or a seller’s temporary location without penalty.4eCFR. 16 CFR Part 429 – Rule Concerning Cooling-Off Period for Sales Made at Homes or at Certain Other Locations The seller must provide a cancellation notice form at the time of signing.5eCFR. 16 CFR 429.1 – The Rule
The rule does not apply when you initiated the contact, for example, by calling the contractor to come give an estimate on a repair you already knew you needed. It also does not cover emergency repairs.6Federal Trade Commission. Buyers Remorse: The FTCs Cooling-Off Rule May Help If a storm-chasing contractor shows up unsolicited and pressures you to sign on the spot, that three-day window exists for exactly this situation. A contractor who tells you to waive it is violating federal law.
Keeping the Paperwork
Both parties should walk away with a fully signed copy on the day of execution. Keep yours alongside the certificate of insurance, every lien waiver, every change order, permit documentation, and warranty paperwork as a single project file. You’ll need it for insurance claims, warranty service requests, and as proof of permitted work when you sell the property. Manufacturer warranties in particular can require documentation of the original materials and methods to process a claim years later.
