How seamless gutters are installed

Seamless rain gutters | ONE Clean Gutter

Gutters are an essential part of any home and serve a valuable purpose by channeling rainwater away from the foundation. You must have the right tools and materials when installing gutters. This brief guide will show you how to install seamless gutters on your house so that you don’t have to worry about them leaking or clogging with leaves and other debris, the ONE Clean Gutter way! Remember to ask for professional assistance first since working with gutters represents a dangerous task.

Step 1

Measure the length of the gutter run and add or subtract material to achieve a total length that is a multiple of the gutter coil’s width.

For example, if you have 4 feet of existing storm sewer pipe and need to install a new section that is 6 feet long, divide 12 (the width in inches) by 48 (the number of inches in one foot). The result is 0.25, which means your new section should be cut so it will fit snugly inside your existing pipe at a quarter-inch from its end. This will allow you to overlap each section by an eighth-inch rather than having seams that are flush with one another.

The easiest way to measure gutters is using string stretched tautly between endpoints such as downspouts or corners where two sections meet at right angles. This makes finding exact lengths easier because it allows you to use simple trigonometry principles on paper rather than needing sophisticated surveying equipment like laser levels or transit stations on-site during construction activities. However, if these tools aren’t available, then skip ahead for more information about how exactly measuring seamless gutters works!


Step 2

Cut and install downspouts at each corner as needed, and at least one per side of the house. Downspouts can be cut to any length.

Your gutters will be installed by cutting them to length, then fitting the pieces together to form a continuous run. Downspouts are connected to the gutter run with downspout extensions, which can be cut to any length. The extensions should be installed at least every 20 feet (6 m).


Step 3

Install downspouts long runs of gutter on both sides of the house as needed, but not more than one every 20 feet.

At the base of these downspouts, make sure they are in a straight line and not kinked or turned. You can use flexible plastic or metal pipe if you need to extend your runs to 20 feet.

Step 4

Trim gutter end caps and downspout outlets from aluminum coil using tin snips or aviation snips.

To cut the gutter end caps and downspout outlets, use tin snips or aviation snips to cut aluminum coil.

You can trim the end caps with tin snips, not too close to an edge of a fascia board.


Step 5

Screw a 60-degree elbow bracket to the fascia board with two #8 1 1/4 inch roofing screws and seal them with roofing cement.

Use a drill or screwdriver to drive the screws for faster installation. Use roofing cement to seal the screws.


Step 6

Cut a piece of aluminum coil 35 inches long using a circular saw with an aluminum cutting blade or a snips.

The exact length depends on your measurements, but the piece should be longer than the width of your gutters so they can be wrapped around them. Cut two more aluminum coil pieces, each 16 inches long, for use at the gutter’s end supports.


Step 7

Slide the first section into the 60 degree bracket until it is flush with the bottom edge of the fascia board, then drive four #8 1 1/4 inch roofing screws through the bracket and into the gutter lip.

Now that you have the first section of the gutter in place, it’s time to move on to the second section. Remember that all sections should be level and flush with the bottom edge of your fascia board. To ensure this is the case, ensure you’re using a level as you work.

Once your second section is securely fastened at both ends and across its entire length, it’s time to install your third section. The process will be the same as before: Slide it into position until it meets up with both ends at 90 degrees (or whatever angle works best for your particular setup). Then, drive four screws through each bracket into its lip at each end and across its entire span.


Step 8

Slide one end of the next section into the first section until it seats firmly against it, then push down on it while you drive four #8 1 1/4 inch roofing screws through its lip, two on each side, into the fascia board below.

Slide one end of the next section into the first section until it sits firmly against it, then push down on it while you drive four #8 1 1/4 inch roofing screws through its lip, two on each side, into the fascia board below. Repeat that process with all the gutter sections in place. Ensure each section is flush with your fascia board and that the end of each gutter is also flush with your fascia board before continuing to install additional sections or screws.

Once you have installed all the sections, push them down against the fascia board with your hand to ensure they are correctly seated. If any of them are loose, drive another screw into each one until it is tight against the fascia board. Then go back over each section with a hammer and tap if necessary until they sit low enough in their brackets.
