Learn to professionally fabricate and properly install aluminum rain gutters.
First, load the roll of coil stock aluminum right to the gutter extruding machine. Then turn on the machine and allow the machine to form about 4 feet of gutter, then immediately turn off the machine. Apply silicone adhesive around inside edge of the aluminum end cap. Use hammer if necessary to lightly tap end cap onto end of gutter for tight fit.

Pinch the end cap onto the gutter using a crimping tool. Now run a bead of silicone along seam where end cap joins the inside of the gutter. Turn the gutter-extruding machine back on to produce the desired length of gutter. Turn off machine and mark the location of the downspout outlet on the inside of the gutter. Use hammer to punch out downspout hole using manual downspout cutter.

Spread silicone adhesive generously around flange of downspout outlet. Wipe dry the area around the hole in the gutter, after which install the downspout outlet. Cut the gutters length by using the machine’s forward-pull guillotine cutter. Install the other end cap onto the remaining gutter end, again using the silicone adhesive and finally the crimping tool.

Place aluminum drop on clips by spacing them every 2 to 3 feet. Holding the gutter against the house fascia, making sure it pitches down toward the downspout ½ inch for every 10 feet of gutter. Fasten gutter to the house with hex-head screws through the hole in the drop-on clips attaching them to the fascia.
