You might be wondering if you can put solar panels on a metal roof. Yes! In fact, metal roofs have superior compatibility with solar panel systems, particularly when compared to asphalt and other types of roofing.
Read on as our team at PRS Roofing in Debary, FL, discusses the benefits of installing solar panels on metal roofs.
Metal Roofs and Solar Panels Are Fully Compatible
Metal roofs are 100% compatible with solar panel energy systems, including standard PV (photovoltaic) and thin-film panels. However, thin-film panels are only compatible with certain metal roofs—standing seam types, in particular.
Many people falsely believe that you can’t put solar panels on metal roofs without drilling holes during installation, which can lead to roof leaks. However, that’s not always the case. Below, discuss some different types of metal roofs and their corresponding mounting methods for solar energy systems.
Standing Seam Metal Roofs
Standing seam metal roofs are the ideal choice for installing solar panels. One common mounting system uses S-5 seam clamps to attach the panels to the seams on the roof with no drilling or holes required. The lack of drilling means that installation will be faster and less expensive than with other types of mounting systems.
Corrugated Metal Roofs
Unlike standing seam metal roofs, corrugated roofs do require drilling during installation. However, with installation from a professional and experienced solar energy company, you face no risk of water leaks or damage after mounting the system. Many installers use S-5 penetrating brackets and straddle blocks to install the solar PV panels, securing them onto the roof so they sit on top of the ridges. To prevent the risk of leaks, they apply commercial-grade sealant after installation.
Metal Tile Roofs
For homes or businesses with metal tile roofs, installers can use a mounting system that doesn’t require any drilling to secure the solar panels to the tiles. The installation uses tile mounts, which look very similar in appearance to the actual roof tiles, providing a pleasing aesthetic. The mounting and installation process is simple, and the tile mounts overlap on the existing roof tiles for a durable and water-resistant fit.
Which Types of Roofs Are Best for Solar Panels?
Standing seam metal roofs are the best choice for mounting solar panel systems, as they don’t require any drilling. For home or business owners who are installing or replacing metal roofs, consider choosing a light color. Light-colored metal roofs reflect the sun more than dark roofs, increasing energy savings.
