A leak after installation
The source needs to be examined. A material defect, installation connection and later damage are different causes and can point to different responsibilities.

A roof can have separate product and installation coverage. The useful questions are what failure is covered, who handles it and which remedy the terms actually provide.
Free roof inspections. Repairs, replacements and commercial roof help.
A leak can arise from a product defect, an installation connection, later damage or an unrelated opening. Those causes can involve different agreements and remedies. A product warranty and an installation warranty therefore need to be read as separate coverage, even when both concern the same roof.
The written terms establish the covered failure, exclusions, claim process and available remedy. Later repairs or equipment changes may affect those terms. Warranty length, transfer rights and any payment remedy come from the agreement that applies to the project.

| Coverage | What it addresses | What changes the answer |
|---|---|---|
| Product warranty | The manufacturer’s stated material defects. | The product, eligible installation, registration requirements, exclusions and remedy. |
| Workmanship coverage | The contractor’s stated installation responsibilities. | The agreement, covered work, exclusions, transfer conditions and how a claim is handled. |
| Insurance | Damage from a covered cause under the policy. | Deductible, settlement basis, exclusions and the insurer’s cause-of-loss decision. |
A term can include limited remedies, prorated amounts or specific installation conditions. Labor, removal and disposal are not automatically included because a product has a long stated term. The coverage needs to be read in its actual written form, with the responsible issuer identified.

The source needs to be examined. A material defect, installation connection and later damage are different causes and can point to different responsibilities.
Past repairs and changes to vents, solar equipment or rooftop units can affect the assembly and applicable terms. The condition and agreement need to be considered together.
A guide gives the background. A free inspection helps relate the work and options to your roof.
