Designing any roof system can be a challenge, and the addition of solar contributes to the complexity of a roof system installation. The National Roofing Contractors Association (NRCA) strongly encourages design professionals to work with NRCA professional roofing contractors as well as follow NRCA recommendations and guidelines for solar roof system design. Please note NRCA's preferred term for solar roof system is photovoltaic (PV) roof system.
