A roofing certificate of completion is a signed document confirming that the contractor finished the roof installation or replacement according to the original agreement, and filling one out well means pulling your project records together before you open the template, then recording what actually happened on the roof rather than what the contract originally estimated. Done right, the certificate releases final payment, triggers recoverable depreciation from an insurance claim, updates your mortgage file, and proves the roof’s age and condition when you sell.
What to Gather Before You Start
Most mistakes on these forms come from working from memory. Pull these records first and the fields fill themselves.
- The roofing company’s full legal name, physical address, phone number, and state contractor license number. Confirm the license is active in your state’s database before you record it.
- Your full legal name as it appears on the deed, your mailing address, and a phone number or email.
- The property address where the work was performed, which may differ from your mailing address for a rental or second home.
- The building permit number your municipality issued before work began. This links the certificate to the public inspection record.
- The original contract price, any signed change orders, and the final amount paid. Mid-project material upgrades or deck repairs need to appear so the certificate matches the invoice.
- Shingle or panel brand and product line, underlayment type and grade, flashing specifications, and any other components installed. Keep each manufacturer’s data sheet; the fire rating, wind rating, and warranty terms come from those.
- The start date and completion date. The completion date starts the warranty clock, which is why adjusters and lenders ask for both.
Filling Out Each Section
Templates vary. Roofing associations and local building departments offer free versions, and some insurance carriers provide their own with fields tailored to claim processing. Whichever form you use, the goal is the same: document what was done with enough specificity that a stranger reading the certificate twenty years from now can reconstruct the project.
Project Identification
Put the property address, permit number, and project dates at the top. These let anyone cross-reference the certificate against the building department’s records. If there is a field for contract or project number, use the number from the original signed agreement so the two documents are easy to pair.
Description of Work
Vague language is where these forms fail. “Installed new roof” tells a future reader almost nothing. Describe the actual scope: tear-off of existing layers down to the deck, any deck repairs or replacements, ice-and-water shield in valleys and along eaves, synthetic underlayment across the remaining deck, drip edges, step flashing and counter-flashing at chimneys and wall intersections, and the final roof covering. If ridge vents, pipe boots, or other penetration flashings were replaced, list those too.
The International Residential Code requires roof assemblies to be installed according to both the code and the manufacturer’s instructions, and requires flashing at wall-roof intersections, slope changes, and around roof openings.1ICC Digital Codes. Chapter 9 Roof Assemblies – 2021 International Residential Code A scope that mirrors those requirements signals an installation that followed accepted standards.
Materials Installed
List each major component by manufacturer, product name, and specification. For asphalt shingles, note the fire classification (Class A, B, or C) and the wind rating. For metal panels, include the gauge and coating type. For underlayment, specify synthetic or felt and the ASTM designation. Metal flashing should be identified as corrosion-resistant with a minimum thickness of 0.019 inches (No. 26 galvanized sheet), per IRC requirements.1ICC Digital Codes. Chapter 9 Roof Assemblies – 2021 International Residential Code This detail locks in exactly what the manufacturer warranty covers and gives future owners or adjusters a clear picture of the roof without climbing a ladder.
Warranty Section
A roofing project usually carries two warranties, and the certificate should keep them separate. The manufacturer warranty covers defects in the materials themselves: cracking, curling, granule loss, premature failure. Asphalt shingle manufacturer warranties commonly range from 25 to 50 years depending on the product line. The contractor’s workmanship warranty covers installation errors like improper nailing patterns, unsealed flashing, or underlayment installed the wrong direction. Workmanship warranties are shorter, typically 2 to 10 years, though some contractors extend them.
Record the duration of each warranty, the start date (usually the completion date), and any conditions that could void coverage. Many manufacturer warranties require installation by a certified contractor or strict adherence to specific instructions. If the contractor holds a manufacturer certification such as GAF Master Elite or CertainTeed SELECT ShingleMaster, note it on the certificate; it often unlocks extended warranty terms. Attach copies of the actual warranty documents so everything lives in one file.
Attachments That Make the Certificate Hold Up
A signed certificate on its own is thin. Three attachments turn it into real evidence.
Photographs
Photos matter most when you file an insurance claim or sell the home years later. At a minimum, capture wide-angle shots from each side of the house showing the completed roof in context, close-ups of the components most likely to fail (chimney and wall flashing, drip edges, valleys, ridge vents, pipe boots), and, if you have them, in-progress shots of the underlayment and deck before the covering went on. Date-stamp every image. Most phone cameras embed geolocation automatically, which ties the photos to the property and date.
Final Inspection Record
In most jurisdictions, a permitted roofing project requires a final inspection before the permit can be closed. The inspector checks fastener spacing for the roofing material, flashing at all transitions and penetrations, and that the permit and approved plans were on site. Note on your certificate whether the inspection passed, the inspection date, and the inspector’s name or badge number. A passed inspection carries real weight: a third party with no financial interest in the project confirmed the work meets local code. If your jurisdiction issues a separate inspection report, attach a copy. Some lenders and insurance carriers will not release funds without evidence that the permit closed with a passing inspection.
Lien Waivers
The certificate confirms the work is done. A lien waiver confirms everyone got paid. Paying your general contractor does not guarantee the subcontractors and material suppliers received their share, and if they did not, they can file a mechanic’s lien against your property even though you paid the contractor in full.
When you make final payment, ask the contractor to sign an unconditional waiver and release upon final payment. If subcontractors or suppliers were involved, request waivers from them as well. Attach the signed waivers to the certificate so the entire financial discharge sits in one place. A title company reviewing the property during a future sale will look for exactly this paperwork.
Signing the Certificate
The certificate needs signatures from both the homeowner and an authorized representative of the roofing company. These confirm that you accept the work as complete and that the contractor acknowledges all contractual obligations are fulfilled. Without both signatures the document carries little weight with lenders, insurers, or buyers.
Digital signatures are legally valid for this purpose. Under the federal Electronic Signatures in Global and National Commerce Act, a signature or contract cannot be denied legal effect solely because it is in electronic form.2Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity E-signature platforms that capture time stamps and IP addresses create an audit trail that is often more reliable than ink on paper. The law requires mutual consent to transact electronically, so make sure both parties have agreed.
If the contractor refuses to sign and the work is genuinely complete, document the refusal in writing, contact your local building department about closing the permit independently, and consult an attorney if the refusal looks like leverage for disputed charges. Do not sign a certificate accepting work when real deficiencies remain unresolved.
Where the Copies Go
Once the certificate is signed, send copies to everyone who needs one.
Your insurance carrier needs it to process the final claim payment. When a homeowner’s policy covers the roof at replacement cost, the insurer usually pays actual cash value first and withholds the depreciation. Once you submit proof the work is complete, including the certificate, final invoices, and receipts, the insurer releases the recoverable depreciation as a separate payment.3SageSure. Roof Depreciation Life: How It Affects Your Homeowners Insurance – Section: What Is Recoverable Depreciation on a Roof Claim? Save all invoices, signed contracts, receipts, and canceled checks and submit them alongside the certificate.
If you have a mortgage, send a copy to your lender. Lenders track major structural improvements because they affect collateral value, and some loan agreements require notification of significant repairs. For a refinance, a recent roof replacement backed by a certificate can help the appraisal.
Keep your own copy in both digital and physical form. Store the digital version somewhere backed up, such as a cloud drive plus a scanned PDF saved in a second location. Attach the warranty documents, lien waivers, manufacturer data sheets, permit records, inspection results, and photographs to the same file. Buyers routinely request roof documentation during due diligence, and handing over a complete packet can smooth a sale and support your asking price.
