The company guarantees your solar roof's production won't drop below 95% of its original level five years after the initial installation. For example, Tesla Solar has a 25-year power output warranty. A power output warranty is the manufacturer's guarantee that your solar roof won't drop below a specific production percentage within a certain amount of time.

However, most manufacturers will only cover wind damage for 10-15 years. The longest weatherization warranty we've seen is 25 years. In some cases, this warranty will also cover water damage caused by leaks. This warranty will typically cover your roof from any wind-related damage for at least 10 years.
