Step 1

Establish Pitch

Attach a support clip high up on the fascia board, at the opposite end from where the running outlet will be. You will probably find it easier to tighten screws near the roof covering with a hand-held screwdriver rather than a power drill-driver (image 1). Position a clip at the other end of the eaves, lower than the first and at the correct height to give the necessary pitch (image 2). Tie a string line between the two clips to form a guide line (image 3). Make sure the string line is taut and is not caught anywhere, especially if it has to travel around a corner (image 4). Check the pitch with a level (image 5). If it is not as you want it, adjust it by slightly repositioning the lower bracket.

Step 2

Attach Clips and Running Outlet

Attach a third clip three feet away from the first one, with the string line just touching the top edge of the bracket (image 1). Attach a union bracket three feet along from the third clip. Then attach alternate clips and brackets until within three feet of the end (image 2). Remove the string line. Then clip the running outlet into the last, lowest support clip (image 3).

Step 3

Install Gutter

Position the first whole length of gutter by snapping one end of it into the highest clip (image 1). Snap a stop end onto the gutter before moving the ladder to clip the rest of the length in place (image 2). Snap the gutter into the next clip, and then insert its end into the first union bracket (image 3). Snap the next length into the union bracket. Continue installing whole lengths until near the end (image 4).

Step 4

Cut to Length

Mark where you need to cut the last piece of gutter to length. Use an off-cut of gutter to guide you for a straight cut with a panel saw (image 1). File the cut end of the gutter to remove burs (image 2). Position the last piece of gutter and clip it into the running outlet (image 3). Clip a stop end onto the running outlet if it needs one. If the roof overhangs the edge of the house by a long way, you may need to attach a short length of gutter the other side of the outlet, angled down from the eaves into the running outlet.

Step 5

Attach Downspout

Before you begin to install gutters, assemble as much of the gutter system as you can while you are on the ground. Working on the ground minimizes the amount of work you will have to do later while you are standing on a ladder or scaffolding. Assemble a bend to connect the gutter with the downspout, using two offset bends with a length of downspout between them. Adjust the middle section of downspout so that the main downspout will lie against the wall (image 1). Push the bend into the bottom of the running outlet to fit it in place. Then push the downspout into the off-set bend (image 2).

Step 6

Attach Downspout Brackets

Hold a bracket in place at the top of the downspout and draw through the fastener holes to mark the wall (image 1). Use a masonry bit to drill pilot holes at the marked points. Insert wall plugs into them (image 2). Screw the bracket into position over the downspout (image 3). Secure more brackets every three feet along the length of the downspout (image 4).

Step 7

Installing Metal Gutters

Set up a string line for metal gutters just as you do for vinyl. Cast-iron gutters will not have union brackets, but lightweight aluminum involves using a hole cutter to make holes in gutter lengths, allowing running outlets to be positioned as required. Join lengths with a union bracket that creates a watertight seal (image 1). Attach a stop end and clip it into place (image 2). Use a running outlet where the hole has been cut to clip over and around the gutter profile (image 3).
