Step 1.
Mark a point at the
high end of each gutter run, 1” from the top of the fascia. Snap chalk
lines that slope toward downspouts. For runs longer than 35 ft., mark a
slope from a high point in the center toward downspouts at each end. |

Step 2. Install downspout
outlets near the ends of gutter runs (at least one outlet for every 35
ft. of run). The tops of the outlets should be flush with the slope
line, and they should align with end caps on the corners of the house,
where drain pipes will be attached. |
