Step 3: Cut The Downspout Holes

Measure in from the end of the roof to the point directly above where you plan to attach each downspout. Typically, they run inboard of corner trim; how far depends on their bracket's size. Transfer those measurements to the gutter, and cut the downspout holes with a hole saw or with metal shears, as shown.
