Solar Panels and Your Roof - An Overview

Before delving into the details of roof replacement, let’s have a quick overview of how solar panels are typically installed on a roof. Solar panels are mounted on racking systems that attach to the roof’s surface. The mounting method depends on the type of roof, such as asphalt shingles, metal roofing, or tile roofs.

Most solar installations are designed to last for several decades, which means the solar panels are intended to outlive the roof they’re installed upon. However, there are essential considerations to keep in mind when replacing a roof that has solar panels
