Manufacturer coverage
A long advertised term does not mean every leak, storm event, installation error, or accessory is covered for the same period or amount.
Contractor workmanship coverage
Workmanship coverage comes from the roofing company and addresses its installation under the written terms it provides. Ask who stands behind it if crews are subcontracted and how a service request is submitted.
The company, warranty term, covered details, response process, exclusions, and transfer rules should be written—not inferred from a sales conversation.
Questions to ask before signing
- Who issues each warranty?
- What exact roof components are covered?
- Are labor, access, tear-off, disposal, or interior damage included?
- Does the manufacturer require certified installation or registration?
- What maintenance or notice is required?
- How are wind, hail, ice, condensation, and building movement treated?
- Can coverage transfer to a buyer?
- What documentation should the owner keep?
Keep a complete roof file
Retain the signed contract, final scope, changes, invoices, payment record, product information, color and batch details when available, registration, warranty documents, inspection photos, and company contact information.
A warranty is not a substitute for choosing a clear scope and qualified roofing company at the start.
Conditions outside the warranty still matter
Storm impact, ice, building movement, condensation, inadequate maintenance, unauthorized modifications, foot traffic, animals, and work by other trades may fall outside coverage. Read exclusions before assuming a later leak will be repaired without cost.
Solar, skylight, chimney, gutter, and mechanical work can alter roof details. Coordinate those trades with the roof warranty holder and keep records of approved attachments and repairs.
If a problem develops
- Protect people and the interior first
- Photograph the symptom and weather timing
- Notify the correct company promptly
- Do not authorize another permanent repair before understanding claim requirements
- Keep samples or removed material when instructed
- Document inspection dates, findings, communications, and completed work
Four different things are called a warranty
When someone says a roof has a lifetime warranty, ask which of these they mean. The answer is almost always the material warranty, which is the one that excludes labour — meaning a defective shingle may be replaced free while the cost of putting it on the roof is yours.
| Type | Who issues it | What it typically covers | Common exclusions |
|---|---|---|---|
| Material warranty | Manufacturer | Defects in the product itself | Labour, installation error, ventilation faults |
| System warranty | Manufacturer | The full assembly when installed to spec by an approved installer | Registration lapses; non-approved components |
| Workmanship warranty | The installing contractor | Defects in how it was installed | Ends if the company ceases trading |
| Finish or coating warranty | Manufacturer (metal) | Fade, chalk, adhesion of the coating | Cosmetic thresholds; damage from cleaning |
What voids coverage more often than anything else
The ventilation exclusion deserves particular attention, because it is both frequently invoked and frequently justified. A poorly ventilated attic genuinely does age a roof from underneath, and a manufacturer declining a claim on those grounds is often technically correct. Getting the ventilation right protects the coverage as well as the roof.
- Inadequate attic ventilation — a common exclusion and a common real cause
- Installation not to the manufacturer's specification
- Registration never completed after installation
- Repairs made by another contractor using non-compatible materials
- Third-party attachments — solar mounts, satellite dishes, equipment
- Pressure washing or aggressive cleaning
