Install your Gutters without Hiring a Contractor

If you have the right tools, supplies, and simple skills, you might be able to install gutters yourself. If you don’t want to hire a professional, here are some general steps you can follow:

1. Measuring the Roof and Purchasing Materials

Here are the points you need to consider:

A. Measure the Length of the Roof

Rain gutters must be fastened to the fascia and extend all the way to the downspout on the roof. To find the gutter’s length, use a measuring tape. When a gutter run is more extended than forty feet (12.2 meters), it should be pitched downward from the middle and directed towards a downspout on either end. The gutter will slope down to the left or right towards a single gutter if it is shorter than this length.

Use caution when taking measures, whether from the top of the roof or a ladder: don’t lean unsupported, don’t set up a ladder on uneven terrain, and don’t use shoes that don’t have enough traction.

B. Purchase Additional Materials

For gutter material, fascia brackets, and downspout(s), visit a home improvement retailer. Approximately every 32 inches (81.3 cm), or every other rafter tail, a fascia bracket needs to be fastened. For instance, dividing the length of the roof by 32 inches (81.3 cm) yields 13.12, indicating that at least 35 feet (10.7 m) of gutter and 13 fascia brackets must be purchased.

Purchase one downspout if your gutter is shorter than 40 feet (12.2 meters) and two if it is longer. Steer clear of areas with electric meters, walkways, and hose bibs.

Gutters range in width from 4 to 6 inches (10 to 15 cm). Ensure that the gutter you use is appropriate for your roof’s size and the frequency of rainfall in your area. Use an online gutter size calculator if you need clarification on the ideal gutter size for you.

C. Mark the Starting Point of the Gutter run 3.2 cm Below the Eaves Flashing

The sheet metal components at the roof’s edge that shield the building’s exterior are known as eaves flashing. Mark the beginning point precisely 1.25 inches (3.2 cm) below the fascia’s flashing, which is the long, straight board that runs down the bottom border of the roof. In the event that your roof spans more than forty feet (12.2 meters), place a chalk mark in the center of the fascia. This indicates the beginning since the gutter descends from the center to the left and right.

Mark the beginning point at either the left or right side of the roof if your roof is less than forty feet (12.2 meters).

D. Determine the Endpoint of the Gutter Run Using a 1⁄2 inch (1.3 cm) Downward Slope

Find the chalk line that indicates the gutter run’s highest point. From this point on, every ten feet (3.0 m), trace a line in chalk on the fascia, moving down 1/2 inch (1.3 cm) for each point.

For instance, a gutter that is thirty feet (9.1 meters) long will stretch from one end of the roof to the other. This implies that you will draw three chalk lines down the fascia, the last of which will indicate where the gutter run ends. From the tallest point, the first line will be 1/4 inch (0.64 cm) down, the second, 12 inches (1.3 cm) down, and the final line, 34 inches (1.9 cm) down.

Install gutters 2.5–3.8 cm (1–1 1⁄2 in) beyond the endpoint to collect rainwater from shingles that overhang.

E. Snap a Chalk Line Between the Start and End of the Gutter Run

Find the ends and place a nail over each one. To drive the nails into each point, hammer them firmly in place at the top. At the beginning of the gutter run, hook one-half of the chalk line onto the nail. After dragging the thread to its terminus, hook it over the nail.

Once the chalk line is in place, pull up straight from the center, allowing the string to break.

Use white and blue chalk lines because red paint can seep into your fascia.

F. Mark the Location of Each Rafter Tail at the Chalk Line

Rafter tails can be identified by their nail heads and are typically 16 inches (41 cm) apart in the middle. Using a piece of chalk, make a distinct chalk mark at each location.

To make it easier for you to tell them apart, use a color other than the chalk line.

2. Attaching the Downspout Outlet and Caps

Here are the points you need to consider:

A. Mark the Downspout Outlet

Take a measurement starting from the corner of your house and ending at the downspout’s center. Now, transfer this measurement to the gutter and use a marker to indicate the outlet’s center on the gutter’s lower side. Make a V-shaped start hole with a chisel and hammer. With the chisel angled 45 degrees away from the gutter, bang the end down firmly.

As you chisel the beginning hole, place the gutter face down on two scraps of wood for support.

To avoid this step, choose a gutter piece that has an outlet already attached.

B. Remove the Outlet Hole

If cutting clockwise, use green snips; if cutting anticlockwise, use red tin snips. Make sure to trim the area outside the outlet line by 1/16 inch (0.16 cm).

Whatever direction you are most comfortable cutting in is acceptable: clockwise or anticlockwise.

C. Attach the Outlet into the Hole and Waterproof it with Silicone Glue

In the hole, insert the outlet. Make two 1/8-inch (0.32 cm) holes with an electric drill for the rivets. After removing the outlet, seal the opening’s surround with a bead of silicone gutter sealant. As soon as possible, slide the outlet into the hole and screw the rivets through.

Use rivets with a diameter of 1/8 inch (0.32 cm).

D. Connect the End Cap(s) to the Gutter Using Silicone Sealant and Screws

Place the cap in its designated hole and screw it in a single sheet of metal. While the cap is being held in place temporarily, drill another hole that is 1/8 inch (0.32 cm) in diameter and insert a pop rivet into it. After taking out the temporary screw, put a rivet in the same spot.

Once the cap is riveted together, waterproof it by running a bead of silicone glue down the seam. Smooth the silicone with a putty knife and press it into the joint.

3. Mounting the Gutters

Here are the points you need to consider:

A. Cut the Gutters Size with a Hacksaw and Heavy-Duty Tin Snips

Using an erasable marker, mark the gutter’s cutting point. Using your dominant hand, grasp the handle while maintaining your index finger parallel to the top and pointing in the direction of the cut for stability. Hold the top of the frame by the wingnut with your other hand. Utilizing your non-dominant hand to apply downward pressure and your dominant hand to move forward and backward, move the saw back and forth.

B. Attach the Gutter’s Fascia Brackets to the Rafter Tails

At each chalk mark, drill a 1/8-inch (0.32 cm) pilot hole through the fascia and into the rafter tails. Next, fasten the fascia brackets with stainless steel lag screws that are at least 2 inches (5.1 cm) long and 1/4 inch (0.64 cm).

  • To facilitate the lag screws’ penetration of the fascia, apply soap to them.
  • Examine the manufacturer’s suggestions specific to your gutter type.
  • A lot of gutter hangers have lengthy screws that insert into the wood and into your gutters. Turn them carefully at first so they can catch before trying to screw through the metal.

C. Mount the Gutters to the Fascia Brackets

After fastening the fascia brackets to the rafter tails, position your gutter inside of them. Till the gutter’s edge next to the fascia locks into the bracket’s back hook, rotate your gutter upward (away from you).

In case the gutters are not mounting properly, take them off and put them back on, being careful to rotate the fascia bracket hook so that the gutter edge closest to the fascia is underneath it.

D. Secure the Gutters to the Fascia Brackets Using Machine Screws

Make a hole on the front side of the gutter that is 3/16 inches (0.48 cm) in diameter using an electric drill. The gutter should next be fastened to the bracket by passing a 1-inch (2.5 cm) #8-32 stainless steel machine screw through the opening and covering it with a flanged nut.

Apply a matching or contrast paint to your gutters and brackets using a spray application.

E. Attach the Gutters to the Fascia

Drive 1 14-inch (1.9 cm) stainless steel hex head sheet metal screws through the gutter’s backside and into the fascia using an electric drill. Make sure you repeat this process once every two feet (0.61 meters) of gutter length.

Make sure your gutter follows the chalk line by double-checking its alignment after each screw has been drilled in.
