A. To use everyone’s favorite word from an attorney, it depends.  Initially its important to determine who holds the warranty(ies). For example, the contractor who installed the roofing system may offer a one year warranty on labor and materials, while the manufacturer of the roofing system offers a much longer warranty.  The best approach is to contact the warranty holder(s) and determine what needs to be done to maintain the warranty prior to any work being done. Oftentimes the warrantyholder(s) will want to inspect the solar energy system installation to make sure the roofing system was not damaged and all penetrations of it are sealed.  Please recall Civil Code section 714.1(a) allows an association to impose reasonable restrictions that: (1) provide for maintenance or repair of roofs & building components and (2) require installers to indemnify or reimburse the association for damage caused by installation or maintenance  of a solar energy system. – Kieran J.
