predrill the fastener holes to pre- vent splitting the wood with the gutter screws. If you can recruit a friend or neighbor to help install the gutter, then do so. The gutter sections can be cumbersome for a single individual to carry up the ladder and nail in place. To install the first section, place the ladder on the roof about mid- way of where the first section would be installed. Position the end of the gutter section about 1 inch beyond the roof line, and tilt it slightly to match the slope of the chalk line. Drive the screw of the center fastener into the fascia. The aluminum gutters are so lightweight that a single screw will hold the section temporarily in place, so you can release it. The center screw serves as a pivot point so you can make adjustments to the gutter slope. Once satisfied, drive home the remaining screws to anchor the gutter. Repeat for the remaining sec- tions of gutter, Start at one end
and work toward the opposite, assembling as much of the gutter on the ground as possible and joining the sections along he eaves by gluing a seamer at each joint.
DOWNSPOUTS Once the gutter is installed, you’ll need to assemble down- spouts that attach to each end drop, and these often require elbows that extend the downspout from the gutter, beneath the eave, to the house wall where it is secured with downspout bands. To measure the length of down- spout between elbows, temporarily duct-tape an elbow to the flange outlet of the end drop. (The flanges attach inside the end drops using sealant and sheet metal screws.) Align a straight edge with the bottom of the elbow to see where the downspout will intersect the house wall. On the wall, temporarily tape the second elbow. Measure between the two downspout sections to determine the length of downspout needed between the elbows, but don’t for- get to account for the overlapping slip-joint (not a butt joint like the gutters). Note that each down- spout and elbow has one end
Make sure to mark your gutter layout so it slopes toward the downspout 1” per 20’.
Align the gutter section with the slope. Drive the gutter fasteners into solid wood. This might require marking the roof’s rafter trails and predrilling the fastener holes.
