How does solar affect your roof?
With proper design and installation, your roof should maintain all its pre-solar integrity. Since the solar system will last 25+ years, you must take into consideration the remaining life of the roof before installing any panels. If the roof does not have much life left, it is recommended you consider a ground mounted system or that you replace it before you install a solar system. On the other hand, if you do opt to install solar and replace your roof in the future years, it's a fairly simple process to remove the solar, replace the roof, and reinstall the array upon completion.
