The Despair of Sagging Gutters

Quick – what’s the most obvious sign that the gutters on a home are dysfunctional?

Right. When the guttering sections are either broken off from the home or separated from each other.

What’s the second-most obvious sign?

It’s not rust spots, since those may not necessarily impact the flow of water. The same goes for holes or cracks, which may be high enough up on the gutter that water doesn’t pass over them on a regular basis.

The correct answer is… sagging gutters!

Sagging guttersSee how this gutter tilts away from the roofline? It looks like a sag waiting to happen.

When gutters sag, they create a place where water can flow downhill in two directions. Eventually, the water spills over the sides of the gutter and onto the ground, where it can erode landscaping, flood basements, or even damage the home’s foundation.

Warped Gutters Can Sag

So what is the catalyst for gutters to sag?

Often, sags come about simply from the warping of the gutter material. Aluminum, vinyl, or steel will expand and contract in summer and winter, respectively since they are constantly being exposed to the elements. To mitigate this problem, gutter manufacturers apply a non-corrosive coating to aluminum gutters and galvanize the steel gutters. Even so, no gutter is built to last forever; so warping will eventually misshape the metal, which could lead to sagging.

Sagging guttersSimply put, Mother Nature is not kind to gutter material.

Poor Installation Leads to Sagging Gutters

Another reason why gutters tend to sag is because they are installed improperly. One common mistake is placing the gutter hangers too far apart
from one another. If these hangers are separated by more than a yard, too much stress may be put on each one; and the uneven weight distribution may lead to sagging somewhere along the guttering run. Also, gutters without the proper pitch may lay the groundwork for sagging. If the gutters are sloped either too much or too little in places, the water may not flow properly but will instead sit inside the gutters. And standing water places excess weight on gutters, which may result in sagging.

Clogged Gutters = Sagging Gutters

But the most frequent cause of sagging gutters is clogs. When leaves, pine needles, and other debris fall into the gutters, they could form blockages which prevent runoff water from flowing to the downspouts. The added weight of both the stopped-up water and debris barrier will usually lead to sagging in the section nearest the clog. And if gutter screws or hooks aren’t carefully affixed to the roofline, small cracks can form at these spots – which create perfect “catchers” for loose debris that can build into a clog.

How to Prevent Sagging Gutters

Sagging guttersThink of this as “sag-proofing” your gutters.

Looking over these causes, it’s fairly easy to figure out how to prevent gutter sagging on your home. First and foremost, your gutters should be kept clear of blockage-forming debris, meaning that you should clean out your gutters two or three times a year (or after an especially heavy storm). Also, you should make sure that your gutters are correctly installed by closely inspecting attachment points for cracks and testing the pitch by running water from a hose through your gutters to ensure that it is flowing to the downspouts. Finally, it’s recommended that you promptly repair or replace any guttering sections which have cracks, holes, or widespread rust; otherwise, these problems could get worse and result in sagging gutters.

I recently had the Gutter Helmet by Harry Helmet installed on my house. It not only looks amazing, but the guys arrived on time, were professional and efficiently got the job done. I am very satisfied with Gutter Helmet's attention to detail and fulfilling their work as promised. I will definitely tell my neighbors about the Gutter Helmet.
I have had Gutter Helmets for 20 years. In all that time I've never had a problem until recently a bird's nest found its way into one of my gutters. The installer who came to replace the product was the same installer from 20 years earlier. Now that's impressive. Everyone at Gutter Helmet inclusive of the office staff were professional and a pleasure to work with.
Gutter Helmet by Harry Helmet just replaced our roof and we could not be more satisfied. The crew showed up early, worked all day and stayed late, were professional and caring regarding the project and the surrounding impact it had on our property and home. They completed the roof quickly and it looks simply amazing!
VERY happy with our entire experience adding Gutter Helmet by Harry Helmet to our house. Installing this was a great value for us. The gutters are working perfectly in heavy downpours and with year-long leaves and debris coming down from our river birches. Terrific customer service and a first class product.
We needed our roof repaired due to wind damage. After several quotes, Gutter Helmet was the only company that went into our attic to look and see if more damage had occurred. If it wasn't for them taking the extra time to look at everything, we would have had rotting wood under our new roof. They were very professional and gave a fair quote.
We just had Gutter Helmet installed on our gutters and couldn't be happier. They provided us with useful information about Gutter Helmet and cleaned up everything, leaving no mess behind. We definitely recommend Gutter Helmet to anyone considering this product.
