The answer to 'ridge vent warranty' is that most ridge vents come with a limited lifetime warranty from the manufacturer. This means the vent itself is covered for as long as you own your home, typically 20-30 years or more. The warranty covers any defects in the materials or workmanship of the vent, ensuring it will function properly and maintain its integrity over time.
However, the warranty does not cover issues caused by improper installation, lack of maintenance, or damage from external factors like severe weather. To ensure your ridge vent warranty remains valid, it's important to have it installed by a licensed and experienced roofing contractor, and to regularly inspect and clean the vent as part of your home's roof maintenance.
