Gutter eave section — hidden hangers and drip edge lapped into the gutter
A gutter hangs on hidden hangers screwed into the fascia (~24″ o.c., tighter in snow/wind zones), and the drip edge must lap DOWN INTO the gutter — stop it short and water runs behind the gutter and rots the fascia.
What this diagram shows
A section through the eave showing how a gutter mounts. The gutter hangs on hidden hangers that screw through its back into the fascia board, spaced about every 24 inches (closer — 18 inches in heavy snow, 12 to 16 in extreme snow or high-wind zones). The roof drip edge bends over the roof edge and laps down INTO the back of the gutter, so runoff drops into the trough; if the drip edge stops short, water runs behind the gutter and rots the fascia. Two elbows and straps are used per downspout.
