Roof Warranties Explained
Roof warranties provide property owners with protection and peace of mind by covering certain types of defects or failures in roofing systems. Understanding the different types of roofing warranties helps ensure you know what is covered, for how long, and what responsibilities fall on the building owner versus the contractor or manufacturer.
Warranties are particularly important in both Residential Roofing and Commercial Roofing projects due to the significant investment involved and the expected lifespan of modern Roofing Materials.
