Are Solar Panels Bad For Your Roof? Explained
Learn whether solar panels damage roofs, the risks, benefits, and best practices for safe installation.
While solar panels can usually be safely and effectively installed on all roof materials, the exact installation processes may differ. As such, there is no "best" roof for solar – panels can go on just about any roof material. Below, we'll look at the various roof materials and how installers secure solar panels to each.
Ballast systems are simply a weighted racking setup that holds solar panels in place. If you need to drill into your flat roof to install solar panels, don't worry – your solar installer will ensure that the holes they drill are as small as possible and sealed correctly to avoid roof damage or leaking.

Solar panels and mounting equipment add approximately 3-4 pounds per square foot of additional load to your roof structure. Key evaluation factors include: If your roof needs replacement, complete this work before solar installation.
