Sagging Gutters

How To Fix A Sagging Gutter Like A Pro

Kenneth Wilson

As a homeowner, it is important to keep your gutters in tip-top shape. Gutters can go unnoticed and cause problems to your home over time. Your gutters are responsible for moving water to minimize damage to your home, such as flooding. When it rains, they channel water flow from the roof into the downspouts and guide it to areas outside the home. Depending on the material, they can last anywhere from 25 to 50 years if they are well maintained.

The Causes and Effects of Sagging Gutters

Gutters are an essential part of preventing drastic damage to your home. Over time, they can warp which leads to sagging. When the gutter sags, it forms a gap where trapped water can flow behind or over the gutter. One of the most common causes of sagging gutters is a blockage from leaves, debris, and other materials. This blockage prevents the water from properly flowing into the downspouts, which can cause erosion or flooding in a basement.

What Are The Average Costs for Gutter Repairs?

The cost for gutter repairs can vary depending on how much the parts costs, the height of your home, the length of your gutters, labor costs, and other taxes. These costs can range from about $70-$300. If you hire a professional, they can fix problems such as clogged, dented, sagging, erosion, leaks, and more. Moreover, the cost for gutter repair depends on the material.

The Pros And Cons Of Gutter Materials

There are four commonly used gutter materials to choose from: aluminum, copper, galvanized steel, and vinyl.

Aluminum is the most commonly used of the four.
  • LightWeight
  • Affordable
  • They Can be Resistant to Corrosion
  • They may form dents over time
  •  It requires more maintenance
  • Temperature changes can affect the material
  • Typical wear and tear that may require painting over chipped material
Copper gutters are another option if you are looking for an upgrade or a shiny finish to your home.
  • Less maintenance
  • Better durability
  • No rusting, cracks, or tearing
  • If maintained properly, they can last up to 50 years
  • They are more pricey 
  • You can only use copper materials
  • Must be tailored for your house
  • Requires a longer installation process
  • It is best to hire a professional that has worked with copper gutters
Galvanized Steel Gutters are one of the most popular and are recommended by contractors. They have a zinc coating to fight against harsher elements, but they rust over time.
  • Less maintenance
  • Less expensive compared to aluminium gutters
  • Durability
  • Sustain less damage from debris
  • They tend to sag over time
  • They can rust over time
  • It is  recommended to conduct recurring inspections to avoid extra costs
Vinyl gutters are made of polyvinyl chloride (PVC) plastic resin and are a lot cheaper than aluminum gutters.
  • LightWeight
  • They are resistant to dents and corrosion
  • Easier Installation
  • Shorter Lifespans
  • Not the most reliable for heavier rainfall
  • Vulenrable to extreme temperatures

How To Repair A Sagging Gutter

Before you begin the repairing process, you need to identify what is causing the gutter to sag. The cause can be anywhere from a dent, a bend, or the supports loosening or breaking.  If you have metal gutters that are torn or bent, you may have to either remove or replace the entire gutter section. If the sagging is a recent issue, grab a ladder and carefully inspect the gutter. Oftentimes, the supports can be replaced and your gutters will be back in good use.

A sagging gutter repair/replacement depends on the cause of the sag and the material. Here are the tools you will need:


  1. New gutters
  2. Hammer/Pry bars
  3. Nails
  4. Downspouts
  5. Ladder
  6. Gutter sealant/Weather-proof caulk
  7. End caps
  8. Snips
  9. Gutter brackets
  10. Screwdriver
  11. Corner joints
  12. Drill
Tools to use

It is important to use safety equipment such as goggles, gloves, and a helmet/hat.

Begin by taking a look a the gutter from each end. Check for missing, broken hangers or if they are hanging low in certain places.

Gutter Brackets

Find out where your gutters are sagging. Using a screwdriver, and remove the section from each bracket.

Fill in the screw holes with caulk or sealant and let it dry.

After the sealant dries, use a drill to drill in the holes.

Attach the brackets to the new drill holes.

Re-apply your gutters.

Gutter Spikes


Find out where the gutter spikes are loose.


Use a hammer or pry bar to pull the spikes from the gutter.


Check to see if the spikes are threaded.

  • If they are threaded, you can reuse spikes that are not damaged.
  •  If they are not threaded, you will need to replace them

Use a screwdriver to insert the spikes into the gutter hole. Make sure they are tightened and secure.

Gutter Hangers


Find out where your gutters are sagging and use a screwdriver to remove the gutter hangers from under the roofing material or shingles.


Check for damaged gutter hangers and replace if necessary.


Insert the new hangers and make sure they are tightened. You can install the hangers in a slightly different place in your roofing material or shingles for better security.

How To Replace A Sagging Gutter

If your gutters cannot be repaired or have recurring damage, you may need to replace them.

  • Remove the downspouts.
  • Place the ladder under the gutter and remove elbow.
  • Apart downspout and put it aside.
  • Remove the screws that fasten the gutter hangers.
  • Once all the hangers are removed, remove the old gutters.
  • Scrape away old sealant.
  • Make sure fascia isn’t damaged after removing the gutters.

Here’s how to install new gutters:

  • Measure the old gutters to determine how much material you will need. This also applies to the end caps, downspouts, and elbows.
  • Using the snips, cut your new gutters to the necessary length.
  • Cut a two-inch notch to attach the corner pieces.
  • Add a bead of sealant along the corner with about 1-1 ½” in from the edge of the material.
  • Attach the front lip of the corner to the notched part of the gutter.
  • You can use a rivet gun to install each rivet in place.
  • Attach the seam with gutter sealant. Apply sealant over the new rivets.
  • Measure each downspout and cut the outlet holes. Cut about 1/16” to ensure they are secured.
  • Drill 1/8” holes into the outlet and apply gutter sealant.
  • Place the downspouts into the outlet holes and rivet the pieces together.
  • Line up the top of the gutters and attach them to the fascia
  • Slide the gutter material underneath the shingles. Take a hammer and nail them down. (It is recommended to space them out every two feet.)
  • Reinstall the gutter hangers and install the downspouts.
