Repairs can typically take place without removing any solar modules. Your roofer can just work around the equipment since there is space and walkways to do so. However, if they need to repair an area covered by modules or if you need to re-roof, a coating is recommended. A coating, like silicone, can extend your roof life for 20+ years. In the case of repairing an area covered by modules, it is best to remove the modules and have the roofer do their work, and then have the modules put back. This can be a bit costly; we estimate approximately $225 per module, to have the modules detached from the wiring, removed from the racking, and then reinstalled. To do a coating you can hire a roofer who is experienced in working around solar and they can coat the roof with the modules left in place, they will charge more for the additional time and preparation to do this.
