Snapping Layout Lines
You need to mark the gutter’s highest point running on the fascia, which is 1 ¼ inch beneath the metal drip edge’s flashing. And on the other fascia’s end, proceed in marking the gutter run’s low end. You need to remember that the slope must be half an inch at an approximate figure per 10 ft of the run. Now you need to start snapping a chalk line right between the two points.
Attaching Fascia Brackets
You need to find the rafter tails present behind the fascia. These tails are mostly spaced on the centre by 16 inches. Ensure that you lookout for the telltale nail heads. Proceed in making a mark on the chalk line. You need to do it for all the rafter tails.
Start drilling a pilot hole of 1/8 diameter via the fascia and inside the rafter tail on every mark. Use ¼ lag screws of stainless steel for fastening the fascia brackets. It should be long enough for penetrating the rafters by two inches.
You need to start cutting the gutter section or area to length using aviation snips and hacksaw. But you can also do so by using a power mitre of 12 inches with a saw fitted accompanied by a blade of carbide-tipped finishing. If your gutter tends to continue around the corner, then proceed in cutting the required angle on end.
If the run needs a gutter of two sections, you need to start overlapping them by eight inches. You should also utilise pop rivets or stainless-steel screws that are self-tapping and of 3/8 inches. Do this in 2-rows of four each for joining them.
Attaching End Caps
Now you need to start attaching a spherical type of end cap with the aluminium pop rivets towards the gutter’s square-cut end. Proceed to temporarily hold the end cap in the perfect place using a metal screw of a single sheet. After that, you can start drilling a hole of 1/8 inch diameter and install the pop rivet. To ensure a watertight joint, you need to start sealing the rivets, and the end-cap seam present on the gutter’s inside. You can do so by using a siliconized caulk of top quality.
Cutting Downspout Holes
You should utilise a downspout outlet for marking the downspout’s location on the gutter’s low end. Start turning your gutter upside down for doing this and proceed in placing the outlet back on top. Now you should begin tracing around the outlet’s inside for marking the hole of the downspout on your gutter. You should drill a hole of ¼ inch diameter through the circular outline’s centre. Proceed in turning the gutter over, and now you should start cutting the downspout hole with a saw of a four-inch diameter hole chucked inside the drill.
After lag screwing your brackets to the fascia, you need to lay your gutter into it. You should rotate your gutter in an upward manner until its back edge starts slipping inside the hooks above the brackets’ back. You need to start drilling a hole of 3/16 diameter in the gutter’s front edge via the hole of screw mounting in every bracket. Now you need to utilise a 1-Inch machine screw of #8-12 stainless steel and the flanged nut for securing the gutter to your bracket.
Forming a Strip-Miter Joint
Start covering the joint present between the two gutter lengths on every corner using a strip mitre. It can be a wide aluminium strip of three inches. Now start tightly wrapping the aluminium strip around your gutter’s underside. Proceed to safely secure it using sheet metal screws or eight pop rivets.
Proceed in cutting a triangular area from the strip mitre’s top using snips. Now you can begin folding down the two flaps right around the gutter’s top edge. You can add siliconized caulk of high quality to make your joint waterproof.
Downspout To Gutter Connection
Begin securing the outlet of the downspout to your gutter using four screws or pop rivets. Proceed to screw the downspout elbow to your outlet tube, which protrudes down from your gutter. Start holding another elbow right against the home and proceed to cut a downspout piece for fitting between the two elbows. You can utilise a needle-nosed plier for slightly crimping the elbow in fitting inside the downspout. Now you should fasten all the parts or components together using screws or pop rivets.
