What is a Workmanship Warranty for a Roof?
A workmanship warranty (sometimes called callback protection) is the contractor’s promise to fix any install-related defect in the roof at no additional cost to the homeowner for a stated period of time. It covers labor and is separate from the manufacturer’s product warranty, which covers the shingles themselves. Workmanship warranties are written and issued by the contractor; product warranties are written and issued by the shingle manufacturer. Both should appear on every reputable roofing contract.
Two separate warranties on every roofing project. The contractor’s workmanship warranty (cyan, left) covers install-related defects for a stated period. The manufacturer’s product warranty (right) covers shingle product defects separately.
What does a workmanship warranty cover?
A workmanship warranty covers install defects: things the contractor did or did not do during the installation process. Typical covered items include:
- Improperly nailed or under-driven shingles that lift, leak, or fall off.
- Flashing installed incorrectly at walls, valleys, chimneys, skylights, or vent pipes.
- Missing or skipped underlayment or ice and water shield in the proper zones.
- Leaks resulting from install error (not from product failure or ice dams or hurricane damage).
- Inadequate ventilation installed contrary to the spec on the contract.
- Tear-off damage to the deck or framing that should have been repaired before new install.
What it generally does NOT cover: shingle product defects (manufacturer’s warranty), storm damage or natural disasters (insurance), normal wear and aging at end of expected life, neglect or owner-caused damage, and changes the homeowner made after install. The two warranties together cover most failure modes but neither covers everything.
What is the average workmanship warranty on a roof?
In Virginia and Maryland, typical workmanship warranty terms by contractor tier:
| Contractor Tier | Typical Workmanship Warranty | Notes |
|---|---|---|
| Budget / handyman roofer | 1 to 2 years | Often verbal; rarely fully transferable |
| Standard licensed contractor | 2 to 5 years | Written contract terms; transfer rules vary |
| Premium contractor | 10 years | Often transferable; backed by contractor’s surety bond or insurance |
| Manufacturer-certified premium tier | 25 years (Owens Corning Platinum, GAF Master Elite Golden Pledge) | Backed by the manufacturer in addition to the contractor; transferable |
The huge gap between budget (1 to 2 years) and premium (10 to 25 years) is a major reason to favor a manufacturer-certified contractor. Even at a slightly higher install cost, the workmanship warranty alone is often worth the difference.
How long is a contractor liable for a roof?
Two answers, depending on how “liable” is defined.
- Workmanship warranty liability: for the stated period of the warranty (1 to 25 years depending on tier). After expiration, the contractor is not contractually obligated to repair install defects.
- Statutory liability (Virginia and Maryland): beyond the workmanship warranty, both states’ construction-defect statutes typically allow homeowners 5 years from completion (Virginia) or 10 years from completion (Maryland) to bring suit for latent defects, regardless of warranty terms. After the statutory period, the legal cause of action expires.
- License-related liability: for as long as the contractor is licensed and operating in the jurisdiction. The licensing board (MHIC in Maryland, DPOR in Virginia) can sanction a contractor for past poor work even outside the statute of limitations.
The practical answer: a roof should last 25 to 30 years; the workmanship warranty should cover the install years, and after that you are relying on the shingle quality. Storm damage and warranty disputes get resolved through insurance and product warranties rather than the contractor’s workmanship warranty.
Workmanship warranty vs manufacturer warranty
Two warranties, two issuers, two different scopes.
| Workmanship Warranty | Manufacturer Warranty | |
|---|---|---|
| Who issues it | Contractor | Shingle manufacturer (Owens Corning, GAF, CertainTeed, etc.) |
| What it covers | Install labor and workmanship defects | Shingle product defects (algae, premature failure, granule loss) |
| Typical term | 2 to 25 years depending on tier | 25 to 50 years (often prorated after year 10) |
| Transferability | Varies; premium tiers often transferable | Typically transferable once (with fee) |
| What voids it | Owner-caused damage, third-party work, neglect | Improper install (which is why install certification matters), inadequate ventilation, owner-caused damage |
| Who you call when there is a problem | The contractor | The manufacturer (often through the contractor) |
If the contractor is out of business when a problem arises, the manufacturer warranty still applies but the workmanship warranty is effectively gone. This is why hiring a contractor who is likely to still be in business in 10 to 25 years matters.
What DreamHome offers
DreamHome includes a 10-year workmanship warranty as the standard offering on every roofing project, written into the contract and transferable once with notification. Premium tier installs using Owens Corning Duration shingles with the OC Platinum Preferred Protection package extend the workmanship coverage to up to 25 years as part of the manufacturer-backed Platinum Protection bundle, with the manufacturer warranty also covering the labor portion (rare and valuable; most manufacturer-backed warranties exclude labor).
Every workmanship warranty issued by DreamHome includes documented coverage scope, a stated transfer process, and contact information for both warranty claims and (in the unlikely event of contractor non-performance) the relevant state licensing board.
Red flags on someone else’s workmanship warranty
- “Lifetime workmanship warranty.” Vague marketing language with no defined term. “Lifetime” typically means “as long as the contractor stays in business,” which is often shorter than a stated 10-year warranty.
- Workmanship warranty not in writing. Verbal warranties cannot be enforced. The terms must be in the contract or in a separate written certificate.
- Non-transferable warranty on a property you plan to sell. Reduces resale value; the new homeowner gets nothing. Premium tiers should be transferable.
- Warranty term shorter than the manufacturer install certification requires. Owens Corning Platinum requires a specific minimum contractor warranty; less than that disqualifies the install from the bundled Platinum Protection coverage.
- Workmanship warranty offered without manufacturer warranty registration. Both should be registered at install. If only the contractor’s warranty is offered, the manufacturer warranty defaults to a much shorter prorated tier when the homeowner tries to use it.
- “Callback protection” without a written term. Same problem as above. Get the years and the scope in writing.
