Core System Clearance
The foundation of the visit. Leaves, twigs, seed pods, and shingle grit are removed from the troughs, downspouts are flushed until they run clear, and any gutter guards on the system are cleared of surface debris. Grit deserves specific mention: as asphalt shingles age they shed granules continuously, and that mineral sediment settles into the bottom of the trough where it holds moisture and accelerates corrosion. It does not blow out, and it does not wash out on its own.
