Put simply, a Diamond Bar roof with working drainage outlasts an identical roof covering without it by years. Two visits a year keeps a Diamond Bar roof honest: clear the valleys and gutters before the rains, and check the flashings once past the earliest heavy storm. In practice, the majority of Diamond Bar roofs that fail early fail at a penetration someone could have resealed for a few hundred dollars.
