What a workmanship warranty is
Two warranties usually cover a finished job. The manufacturer warrants the shingles, the windows or the furnace. You warrant the installation: the flashing you bent, the seams you set, the connections you made. This document is the second one. It's a selling point when you quote, and a limit on your exposure once it's written down, because it says exactly what you'll come back for and for how long.
Issue it at the end of every job, alongside the job completion sign-off. The completion date on that form is the date this warranty starts.
What the warranty covers
- Covered work: defects in workmanship on the job described, such as leaks, loose fixtures or failed joints caused by how the work was done.
- Term: a number of years from the completion date.
- Exclusions: normal wear, misuse, lack of maintenance, storms and other acts of nature, settling, and changes made by others.
- Manufacturer warranties: passed through to the homeowner, with registration left to them where it's required.
- Making a claim: written notice within a set number of days of finding the problem, with photos and access for an inspection.
- Your response: a first visit within a set number of days, then repair or replacement of the defective work at your choice.
- Transfer: whether a new owner gets the remaining warranty if the house is sold.
- State-law rights: the warranty adds to, and doesn't take away, any rights the homeowner has under state law.
Warranty mistakes to avoid
- Writing "lifetime warranty" without saying whose lifetime. Use a number of years, or define it.
- Promising to cover the materials. If the shingles fail, the manufacturer's warranty applies; say so, and offer to help with the claim.
- Disclaiming every implied warranty. Some states don't let a contractor waive implied warranties on a home, and the attempt can make the whole clause look unfair. This template leaves them in place.
- No claim process. Without a notice deadline, you hear about a slow leak after it has rotted the subfloor.
Selling products as well as labor?
If your written warranty also covers consumer products you sell, the federal Magnuson-Moss Warranty Act sets rules for how the warranty is written and labeled. The FTC's guide to federal warranty law explains them.

Questions? Answers.
How long should a contractor's workmanship warranty be?
One to two years is common for general remodeling, and longer for roofing or siding. Pick a term you can stand behind and price it into the job.
Does the homeowner need to sign a warranty?
It isn't required, but their signature shows they received it and read the exclusions and the claim process. That helps if a claim is disputed later.
Can the warranty transfer to a new owner?
If you choose. The template has a blank to say whether the remaining term transfers when the home is sold, and on what condition, such as written notice within 30 days of the sale.
