A modular roofing system includes a lower set of co-adjacent rectangular panels locked together by an upper set of co-adjacent hexagonal tiles made from a light-weight rigid urethane foam material coated with a durable outer layer of non-foam polyurethane plastic. The tiles can carry photovoltaic cells that interconnect at opposite ends to adjacent tiles. The cells can be replaced on the existing installed tiles using an aligned locking structure for aligning electrical contacts and sealing the cells. Length adjustable modular gutter tiles terminate an array of tiles along a lower roof edge. |
