On most jobs, moss on a shaded Diamond Bar slope should be treated rather than scraped, since scraping takes the granules with it. We see it on Diamond Bar roofs every week. Clearing the Diamond Bar gutters in late autumn prevents nearly all of the damage the first storm would otherwise cause. Trimming back branches over a Diamond Bar roof removes the debris that holds moisture against the covering and shortens its life.
