Roofing Certificate of Completion: Fields, Uses, Template

By The Roofing Brief Team. Last reviewed: October 2026.

A roofing certificate of completion is a signed document a contractor gives you when a roof job is finished, stating the work is done, matches the contract, and was accepted by the property owner. It records the contractor, the dates, the materials, and any warranty and permit numbers, and its completion date starts real clocks: GAF’s sample System Plus warranty gives the contractor 45 days from installation to register an enhanced warranty, and California Insurance Code 2051.5 gives a California policyholder at least 12 months from the first actual cash value payment to collect the replacement cost holdback.

What a roofing certificate of completion is used for

A roofing certificate of completion is used to prove, to a specific third party, that the roof work was actually finished to spec. Each party reads a different field: GAF’s warranty desk checks the product line and that registration happened within 45 days of installation, a California insurer checks the completion date against its replacement cost deadline, and Philadelphia’s permit system checks the permit number on the uploaded city form.

• Warranty registration. Enhanced manufacturer warranties are registered by the contractor after completion. GAF states its base shingle warranty needs no registration, while System Plus, Silver Pledge and Golden Pledge do, and its sample System Plus warranty sets a 45-day registration window from installation.
• Final payment and lien release. Lenders and title companies release the final draw once completion is documented, usually alongside a signed lien waiver; in California the completion date also starts the 90-day lien clock under Civil Code 8412.
• Insurance. After a claim-funded replacement, carriers may request completion proof before releasing recoverable depreciation; Florida Statutes 627.7011(3) ties those payments to work performed and expenses incurred. See our guide to filing a roof damage insurance claim for where completion proof fits the timeline, and our guide to a recoverable depreciation roof claim for how the holdback is released.
• Permit and inspection closeout. The certificate supports, but does not replace, the jurisdiction’s final inspection sign-off. Some cities use their own form: Philadelphia requires its Roof Replacement Certification Form on the permit.
• Resale. Buyers, appraisers, and their inspectors treat a dated completion record as evidence of roof age and remaining service life.

What fields belong on a roofing certificate of completion

A usable certificate carries the entities a third party needs to verify the job: who did the work, when, on what, and under what warranty and permit. The nine fields below mirror what official forms ask for; the Philadelphia certification, for example, asks for the building permit number, contractor license or PA Home Improvement registration number, roof covering type, and a yes or no on whether less than 10% of the sheathing was replaced.

Field	Why it matters	Who checks it
Contractor name, license number, address	Ties the work to a licensed, insured entity	Insurer, buyer, warranty desk
Property owner and job address	Binds the certificate to a specific roof	All parties
Start and completion dates	Sets roof age and warranty start	Manufacturer, appraiser, insurer
Scope of work (tear-off, deck repair, install)	Confirms the job matched the contract	Owner, lender, insurer
Materials and manufacturer (shingle line, underlayment, ventilation)	Required to register the correct warranty tier	Manufacturer warranty desk
Warranty type and term	Records what coverage was promised	Owner, future buyer
Permit number and AHJ	Links to the jurisdiction’s inspection record	Buyer, appraiser, AHJ
Statement of completion and acceptance	The operative sentence: work done and accepted	Lender, insurer, court
Contractor and owner signatures with dates	Makes the acceptance mutual and dated	All parties

Certificate of completion vs. the other roofing documents

A roofing certificate of completion is one of seven documents people routinely confuse, and the differences decide which one a given party will accept. A certificate of completion is issued by the contractor and confirms the work; it is not the building department’s occupancy approval, not the permit’s final inspection card, not a payment waiver, and not California’s recorded Notice of Completion, which the owner signs and verifies under Civil Code 8182.

Document	Who issues it	What it proves	Common use
Certificate of completion	Roofing contractor	Work finished and accepted by owner	Warranty, final payment, resale
Certificate of occupancy	Local building department (AHJ)	Structure is legal to occupy	New builds, major renovations
Final inspection sign-off	Municipal inspector	Work passed code inspection	Closing the roofing permit
Lien waiver	Contractor or supplier	Payment received, no lien filed	Releasing lender or title funds
Warranty registration / certificate	Material manufacturer	Coverage is active on this roof	Future material or labor claims
Roof certification (wind mitigation)	Licensed inspector	Roof condition and features on an inspection date	Insurance premium credits, resale
Notice of Completion (California)	Property owner, recorded with the county	Date the work of improvement was completed	Shortens lien deadlines to 60 and 30 days

The wind mitigation document trips up the most people. In Florida, insurers use the Uniform Mitigation Verification Inspection Form OIR-B1-1802 for premium credits; the Rev. 04/26 version is required for inspections on or after April 1, 2026, per the Florida Office of Insurance Regulation. That is an inspector’s condition report, not a contractor’s completion record, so sending one when the carrier asked for the other will delay the file.

Who needs a copy and what they check

Five parties may ask for a roofing certificate of completion, and each reads a different line. Keep one signed original and give copies to anyone below who applies to your job; for a GAF enhanced warranty, check that the warranty copy arrives within 60 days of completion.

1. Manufacturer warranty desk: materials, install date, and contractor certification, to activate the correct warranty tier.
2. Insurance carrier or adjuster: completion date and scope, to release recoverable depreciation or apply a new-roof credit.
3. Lender or title company: the completion statement and matching lien waiver, to release the final construction draw.
4. Home buyer, appraiser, or inspector: completion date and permit number, to confirm roof age and legal work.
5. Building department (AHJ): permit number, cross-checked against its own final inspection record.

How to get a certificate of completion from your roofer

You get a roofing certificate of completion by requesting it in writing before the crew leaves, ideally as a contract term so it is not optional. Time it so the dates line up: the contractor’s GAF registration window (45 days) and California’s Notice of Completion window (15 days) both run from the completion date.

1. Put it in the contract. Add a clause requiring a signed certificate of completion at final walkthrough, before the final payment clears.
2. Do the final walkthrough first. Sweep the ground and gutters for nails, check step flashing at every sidewall (IRC R905.2.8.3 for asphalt shingles) and the boot at every pipe, and confirm the scope matches the contract line by line. Our guide to roof inspection after installation lists what to check before you sign.
3. Check every field. Confirm license number, dates, exact materials, warranty term, and permit number are filled in, not blank.
4. Sign together and date it. Both parties sign; the owner’s signature is the acceptance that gives the document weight.
5. Collect the companion documents. Ask for the lien waiver, the manufacturer warranty registration confirmation, and the permit’s final inspection record.
6. Store originals and copies. Keep a signed original; save a scan with your insurance and closing paperwork for resale.

Is a roofing certificate of completion legally binding?

A roofing certificate of completion can carry legal weight, but its effect depends on what it says and on state law. When the owner signs to accept the work, courts and lenders may treat it as acknowledgment that the job was complete, and in California “actual completion” is one of the events that defines completion under Civil Code 8180, alongside owner occupation with cessation of labor and 60 days of continuous cessation. It does not waive your rights over defects unless it explicitly says so, and it does not replace a government inspection.

The certificate’s date can matter in a lien dispute. In California a direct contractor must record a lien within 90 days after completion, or within 60 days if the owner records a Notice of Completion, and other claimants within 30 days of that notice. It is not a warranty by itself; coverage comes from the manufacturer registration and the contractor’s separate workmanship warranty. If a certificate contains a broad release or waiver clause, read it carefully or have it reviewed before signing, because that language can limit later claims.

Free roofing certificate of completion template

A workable roofing certificate of completion template is any single page that captures the nine fields above plus two signatures. The Philadelphia Roof Replacement Certification Form fits on one page with six numbered blocks (permit, owner, contractor, installation, date, notes), which is a good model for length. Copy the structure below and have your contractor complete it at the final walkthrough. Contractors closing out the job can pair it with our roofing invoice template.

• Header: “Roofing Certificate of Completion” with contractor name, license number, and contact.
• Project: property owner name, job address, permit number, and issuing AHJ.
• Dates: work start date and completion date.
• Scope: tear-off, deck repair, system installed, and ventilation.
• Materials: manufacturer, product line, and underlayment.
• Warranty: type (material, workmanship, or enhanced system) and term.
• Statement: “The above work has been completed in accordance with the contract and accepted by the owner.”
• Signatures: contractor and owner, each with a date line.

Pair the certificate with your signed agreement so the scope, product line (for example GAF Timberline HDZ with a named underlayment) and price on both documents match.

Frequently asked questions

What is a roofing certificate of completion?

A roofing certificate of completion is a signed document a contractor issues when a roof job is finished, stating the work matches the contract and was accepted by the owner. It records the contractor, license, dates, materials, warranty, and permit number. Its completion date starts deadlines such as GAF’s enhanced warranty registration window of 45 days and, in California, the insurer’s replacement cost window, which by statute cannot be shorter than 12 months from the first actual cash value payment.

Who provides the certificate of completion for a roof?

The roofing contractor provides it, usually at the final walkthrough. Reputable roofers issue one as standard practice, and you can require it as a contract term. Some cities add their own version: Philadelphia requires the contractor to give the owner a Roof Replacement Certification Form and upload it to the building permit.

Is a certificate of completion the same as a certificate of occupancy?

No. A certificate of completion is issued by the contractor and confirms the roof work is finished and accepted. A certificate of occupancy is issued by the local building department and confirms a structure is legal to occupy, typically for new builds or major renovations. A roof replacement usually needs a permit final inspection (IRC R109.1.6 in jurisdictions that adopt the IRC), not a new occupancy certificate.

Do I need a certificate of completion for insurance?

Often, yes. After a claim-funded roof replacement, a carrier may request completion proof before releasing recoverable depreciation, and some insurers apply a premium credit for a documented new roof. California Insurance Code 2051.5 gives at least 12 months from the first actual cash value payment to collect the holdback. In Florida, the wind mitigation form OIR-B1-1802 (Rev. 04/26) is a separate inspector’s document, not the contractor’s certificate.

What should a roofing certificate of completion include?

It should include the contractor name and license, property owner and job address, start and completion dates, scope of work, exact materials and manufacturer, warranty type and term, the permit number and jurisdiction, a completion and acceptance statement, and both signatures with dates. For a GAF enhanced warranty, also list the qualifying accessories so the contractor can register within 45 days.

Does a certificate of completion act as a warranty?

No. The certificate records that the work is done and accepted; it is not coverage by itself. Warranty protection comes from the manufacturer registration for the materials and from the contractor’s separate workmanship warranty. The certificate helps you activate those warranties by proving completion date and correct installation, which GAF’s sample System Plus warranty requires within 45 days of installation.
