How to Install Steel Gutters Part 3 How to Install Steel Gutters Part 3

Once you have completed the first gutter run of your steel gutter installation, you are ready to connect the runs together and finish your gutter system. Each gutter run, or section of gutter, must connect properly to the next to create a flowing gutter system. As well, you need to also in stall the downspouts into your gutters to create a flow from the gutters to the ground.

Step 6 – Connect Gutter Runs/Pieces

Overlap the end sections by no less than 4 inches. The lapped section closest to the high point of the run should sit inside the gutter section closest to the low point of the run. Apply sealant between the two gutter pieces and attach the sections together using steel screws. Place the screws on the sides of the gutter pieces, never on the bottom of the gutter.

When connecting gutter sections at a corner, you should have already precut 45 degree angles when measuring and cutting your gutter segments for installation. After mounting the gutter run, you need to apply sealant to the outside of both gutter ends that meet to form a corner. Next, attach the corner joint over the sealant and gutter ends and insert steel screws into each side of the corner joint. Again, place the screws on the sides of the corner joint, never on the bottom or middle of the joint.

Step 7 – Install Downspouts

Install a sleeve or saver in the gutter run. A sleeve or saver, called by either name depending on the manufacturer, is a small square piece that fits into the gutter run. The sleeve holds and connects the downspout to the gutter system. Apply a ribbon of sealant along the outer rim of the sleeve and insert the sleeve into the notch you precut in the gutter. Once the sleeve is in place, secure it using a metal screw on each top corner of the sleeve where it meets the gutter. Allow the sealant adequate time to set before proceeding to the next step.

Secure an elbow into the sleeve with a screw on each side of the elbow. The elbow’s angle should point it away from the gutter and toward the house. Now install the elbow extension into the first elbow and align it perpendicular to the house. Then, install the second elbow by attaching it to the bottom of the elbow extension. The second elbow should be as flush to the house as possible.

Now, you need to measure the downspout to see if it is the proper length. Your downspout should extend downward to about 6 inches above the ground. If your downspout is too long, you need to make a cut to the top of the downspout using your hacksaw. Once the downspout is the desired length, insert it into the second elbow. Next, you need to install an elbow at the bottom of the downspout to carry the water to the ground.

After installing the downspout, you need to secure it to your house. Wrap a metal strap around the downspout just below where the second elbow and downspout are connected. Using the proper screws, screw each side of the metal strap to your house. The type of screw that you need for this depends on the type of material used to construct your home. Repeat this step to install several metal straps down the downspout to where the downspout meets the bottom elbow. The placement of your metal straps can vary between 5 feet and 8 feet apart, but should be no more than 10 feet apart.

Once you have completed attaching the downspouts your gutter system is complete.
