How To Install Gutter Hangers To Repair A Sagging Gutter

When our family quickly began outgrowing our home, my husband and I couldn't decide whether to add onto our current home or move into a larger one. One day, when we were checking the local area looking for "home for sale" signs, we saw a sign we couldn't take our eyes off -- there was a large plot of land for sale for a great price in a great location. We had never thought of building our own home before, but after a little research, we realized that it wasn't as costly as we thought, especially considering the great deal we got on the land. The entire process was a learning experience, but thankfully, the building team was very pleasant and helpful. We now love our new home, and I am excited to share our experience on our new blog. I also plan to post many planning and construction tips!

How To Install Gutter Hangers To Repair A Sagging Gutter

Over time, gutters have a tendency to sag, especially in areas with heavy snowfall or leaf accumulation. If your gutters are sagging, then you will need to install additional reinforcing brackets to restore their shape. Below is a list of materials and tools you will need as well as how you can perform the repair:

How to repair sagging gutters - tools and materials needed

  • Gutter hangers - Purchase five-inch long hangers that have a hook at one end and a drip-edge mounting bracket at the opposite end. You will need to use one hanger for every linear foot of gutter, including two hangers for each corner. For example, if the total length of your gutters is 120 feet, with six inside and outside corners, then you will need to purchase a total of 24 hangers.

  • Hex washer self-tapping screws - use ¼-inch hex-head screws measuring between 1 and ½ inches and 2 inches long. Be sure to purchase either zinc-coated or stainless steel screws to protect them from corrosion. The self-tapping feature makes driving the screws through the drip edge along the fascia much easier. You will need a single screw for each hanger.

  • Cordless electric drill with ¼-inch hex driver socket

  • Silicone sealant or roofing cement

  • Step ladder or extension ladder

  • Measuring tape

  • Felt-tip marker

  • Screwdriver

How to repair sagging gutters - step-by-step guide

1. Remove all loose remaining gutter hangers - Before installing new hangers, remove any hangers that have become unattached to the gutter. This will provide you with more room to work during the installation of new hangers.

2. Install the new hangers - Once you are ready to install new hangers, choose an outside corner as a starting point. The first hanger will be installed immediately adjacent to the corner. To install the hangers, use the following procedure for each one:

  1. Grasp the edge of the gutter with one hand and place your thumb on top of the inside lip of the gutter to secure it.

  2. With your other hand, slip the hooked end of the gutter hanger under the inside lip.

  3. Hold the gutter edge and end of the hanger together and push the opposite end of the hanger up to the drip edge. Center the mounting bracket on the drip edge.

  4. While continuing to hold the gutter and hanger in place, insert a hex washer screw into the bracket hole and position the screw so it rests in the hole.

  5. With your cordless drill and ¼-inch socket, drill the screw into the drip edge and fascia behind it. Since it is a self-tapping screw, you shouldn't need to apply much additional pressure to get the screw started. Continue screwing until the bracket is firmly mounted to the drip edge, but be sure not to strip the inside of the hole.

Once you finish installing the first hanger, measure twelve inches and make a mark on the inside of the gutter lip with a felt tip marker. This will mark the location for your next gutter hanger installation.

3. Remove old gutter hangers and seal screw holes - When you come across any existing gutter hangers during the installation process, remove them from the gutter and drip edge or fascia. You may need to use a screwdriver to remove the screws from the old hangers.

After removing the screws and hangers, apply a small dab of silicone sealant or roof cement to the screw holes. This will prevent rot-causing moisture from infiltrating and also help keep wood-eating insects from invading the wooden fascia.

4. Finish installing the gutter hangers - Keep installing hangers every 12 inches along the gutters until you come to inside or outside corners. At that point, install gutter hangers at each side of the corner, regardless of whether they are less than twelve inches from the adjacent hangers. This will provide a stronger mount for your gutters and help them withstand the weight of snow or debris in the gutters.
