To hang gutters, mark the lines, cut the gutter, and attach the fascia brackets. Prepare the gutter by attaching end caps and cutting a downspout hole before installing the gutter and attaching the downspout.Continue Reading
Use chalk to mark the highest point of the gutter. Make the mark on the fascia, the band running horizontally under the roof edge. Mark the low end of the gutter run on the other side of the fascia. Calculate 1/2 inch for every 10 feet of run. Use a chalk line snapper to mark the line.
Fin the rafter tails, which are usually 16 inches on center. Use chalk to mark a line on every other tail. Use a 1/8-inch drill bit to drill a hole into each marked tail. Use 1/4-inch lag screws to attach the fascia brackets.
Use a hacksaw or miter saw to cut gutter pieces to the appropriate length. Cut a 45-degree angle if the gutter goes around a corner. Use an 8-inch overlap for gutter extensions, screwing them together.
Use a sheet-metal screw to hold the end cap in place as you drill a 1/8-inch hole through the two pieces of metal. Install one pop rivet. Remove the screw. Use aluminum pop rivets to finish attaching the end cap to the gutter. Seal with silicone caulk.
Turn the gutter upside down. Put a downspout outlet on top, and trace around the inside. Drill a hole through the center of the outline, and turn the gutter over. Use a 4-inch hole saw to cut the downspout hole.
Position the gutter so that its back edge enters the brackets. Drill a 3/16-inch hole in the front edge of the gutter, drilling through each hole in the brackets. Use 1-inch machine screws and flanged nuts to fasten the gutter to the bracket.
Wrap a 3-inch aluminum strip under the gutter. Use pop rivets to secure the strip. Use snips to cut a triangle out of the top of the stop, and fold the flaps over the edge of the gutter.
Use screws to attach a downspout elbow to the downspout outlet. Cut a section of downspout to connect the second elbow to the first. Insert the downspout into the first elbow, crimping the edge to make it secure. Repeat with the second elbow. Use pop screws to secure the parts.
