As a Minnesota roofing company specializing in green remodeling, we get requests to install roofing for Minneapolis or St. Paul homeowners who plan on having rooftop solar panels installed. We appreciate it when they get us involved ahead of time, because the type of roof that's installed is as important as the solar panel selection. Why does the type of roofing matter when you have solar panels put in? Hopefully those solar panels are going to be up there a long time. Because of that, you want a roof that will last at least as long as your solar equipment.
What Is the Best Roof to Support Solar Panels?We'll start the evaluation with simple mathematics.
- The average expected lifetime of a solar panel is 25 years
- The average expected lifetime of an asphalt roof here in Minnesota is 15 to 18 years; a metal roof should last 60 years or more
