Sagging Gutters: Why They Happen And The Steps To Repair Them

Posted on

If you have noticed the gutters on your home starting to sag, there are several reasons why it may be happening. It could be due to the fasteners loosening, the seams failing, or excess debris. Sagging gutters are not something you need to live with forever, and there are easy solutions for fixing the problem.

Loose Fasteners

Hanging gutters on your home involve using ferrule-and-spike fasteners. They work by placing a tube (the ferrule) through the gutter that acts like a bridge to provide the gutter support. A spike is then driven through your gutter, through the tube, and into the roof's eave. The spike can loosen over time, and once it is no longer in the eave, your gutters can sag. It is also possible that the spike never went deep enough into the eave to reach the rafter, which will cause the spike to loosely hold onto the fascia board with inadequate support.

You can fix this problem by moving the ferrule-and-spike to a new spot on the gutter. It doesn't need to move far, as only a couple inches will work. You need to find a spot that will allow the spike to drive into the solid wood rafter. Adding multiple ferrule-and-spike fasteners is also an option to provide more support.

Failing Seams

Slip joints or seam covers are used when assembling gutters, which are the parts that join two sections together. They attach with adhesive, rivets, or screws. Unfortunately, these kind of joints may fail over time because of how your gutters can contract and expand due to outside temperatures. It's also possible for joints to rust, which will create issues with those seams. The result is gutters that sag or completely fail.

Seam failures can be repaired by removing the seam covers, and sanding off the rust using steel wool and sandpaper. The sanded areas can then be coated with a primer that will prevent rust formation. Apply a new seam cover and reassemble the gutters, using silicone caulk so the seams are waterproof.

Debris Accumulation

If your gutter has an excessive amount of weight in it due to debris, it will put additional stress on the supports previously mentioned and cause sagging. If debris is left to sit, it will become waterlogged and weigh even more, potentially causing your gutters to fail.

The best thing you can do is to clean your gutters every year, and prevent debris from building up to the point where it causes damage.

When your gutters are damaged beyond your skill level for repair, you'll need to contact a local contractor to help repair them for you. Companies like A - 1 Seamless Gutters Inc can help.
