Metal Roofing: The Best Choice for Solar Panels

Metal roofs are a better warranty match. The average use life of solar panels is typically about 20 to 25 years. Long-life asphalt shingles can have a warranty as long as 20 years or so, but that warranty is full of loopholes, typically excluding things like high-winds, hurricanes or other extreme acts of Mother Nature.

Also, they don’t usually cover the labor costs involved with repairs or replacements. Plus, any major repairs or shingle replacements may potentially require the deconstruction and re-installation of the solar array.

Metal roofs, on the other hand, are specifically engineered and pre-fabricated to meet the needs of your building’s climate and location, and warranties are typically as long as 40-years or so. This means your roof will outlast the solar panels, eliminating the expense of removing and reinstalling solar racks and panels until the panels themselves need to be replaced.

Racks are easily installed on a standing seam metal roof. This type of roof system works very well with solar racks, which offer the option of fasteners that lock right onto the standing seams. The metal roofs, with rack locks that fasten to the seams, prevents the need for any penetrations that contribute to water leaks or premature wear over time.

Before you go ahead with a solar power installation, make sure the home’s roof is worthy. If you’re building a new home, consider installing a metal roof from the get-go. If your traditional roofing materials are more than 10 years old, it is probably worth it to install a metal roof over your existing roofing materials – or replace the old roof system entirely – to ensure you give the solar energy system a lasting foundation.
