SOLAR COMPATIBILITY
The Ideal Platform for Solar
Metal roofing provides one of the most effective and reliable platforms for mounting solar photovoltaic (PV) systems. Known for its durability, sustainability, and versatility, metal roofing has become increasingly popular in the growing solar energy market.
Unlike many traditional roofing materials, metal roofs offer a long service life, excellent structural performance, and installation advantages that make them uniquely suited for solar applications.
Metal's Long Service Life
One of the most important advantages of metal roofing for solar installations is its exceptional lifespan.
Research from the Metal Construction Association indicates that coated standing seam steel roofs can last up to 70 years. By comparison, most solar PV systems have an expected service life of about 28–37 years, with an average of roughly 32 years.
Many common roofing materials, such as asphalt shingles or membrane roofing systems, may require replacement long before a solar system reaches the end of its life. This can create expensive complications, as the solar array must be removed and reinstalled when the roof is replaced.
With metal roofing, the roof often outlasts the solar system itself, eliminating the need for costly reroofing during the system’s lifespan.
Lower Long-Term Costs
When evaluating solar investments, the roof and the solar system should be considered as a single long-term asset.
If solar panels are installed on a roof that needs replacement halfway through the system’s lifespan, the entire solar array must be temporarily dismantled during reroofing. This process can involve significant costs, including:
-
Removing solar modules
-
Removing mounting systems and racking
-
Temporary system shutdown
-
Roof replacement
-
Reinstallation and system commissioning
By installing solar on a metal roof with a lifespan of several decades, building owners can avoid these additional costs, improving the overall return on investment of the solar system.
Simple and Efficient Installation
Solar systems are typically easier and more cost-effective to install on metal roofs than on most other roofing materials.
Standing seam metal roofs, in particular, allow solar mounting systems to attach directly to the raised seams of the roof panels. These seams can act as natural attachment points, eliminating the need to drill holes through the roofing surface.
This installation method provides several advantages:
-
Zero roof penetrations, reducing the risk of leaks
-
Fewer components required for installation
-
Faster installation times
-
Preserved roof warranties
The ability to mount solar panels without penetrating the roof surface makes metal roofing one of the most installer-friendly roofing systems available.
Solar Mounting Systems For Metal Roofs
When installing solar on a metal roof, the mounting system is just as important as the panels themselves. High-quality solar attachments are specifically engineered to securely fasten solar arrays without penetrating the roof surface, helping preserve the roof’s integrity, weather resistance, and long-term performance.
Industry-leading attachment systems from S-5! are designed to work seamlessly with standing seam and exposed-fastened metal roofing profiles, providing a secure, durable foundation for solar installations. These innovative mounting solutions simplify installation, maintain roof warranties, and ensure solar systems perform reliably for decades—making them a trusted choice for solar projects on metal roofs.
