Solar energy characteristics of roof

Under normal circumstances, property management companies do not allow park owners to install water heaters on the roof. The main reason is: 1. The roof belongs to the public, not to the top floor owner, because it should not be used by the top floor owner. Second, installing a water heater on the top floor will easily damage the waterproof treatment of the roof and cause the house to leak rain. Third, the installation of solar wiring is to take the flue of the building, and it is easy to block the flue when sitting on the rice, causing odor. Fourth, for a good property community, if you look at the roof from a distance, all the water heaters will directly affect the overall appearance of the community, and will also affect the appreciation of housing prices in the community.
