Gutters, like every exterior part of your home, are exposed to all sorts of weather conditions that can cause structural damage. Over time, your gutters can begin to sag, which can be due to a number of reasons, ranging from a buildup of organic debris to simply heavy precipitation. If your gutter sags enough, it will no longer allow water to drain properly off of your roof, which can cause the gutters to sag even further or even collapse. Water will be more likely to leak from your gutters, which can then seep into your basement, leading to water damage and mold and mildew growth within your home. Fixing sagging gutters as soon as you notice them can help prevent these problems from occurring and can help with further roof repair issues in the future.
What You'll Need
You should have a hammer, a crow bar, a ladder, someone to spot you while you're working, and either gutter hangers or gutter spikes, depending on which type of supports are used to hold up your gutters. If you have gutter hangers, you'll need an impact drill and screws as well. All of these items can be found at most hardware stores.
Fixing Sagging Gutters
The first step to fixing your sagging gutters is to identify why the gutters are sagging and how bad the damage is.
Climb up on the ladder, with your helper spotting you as you climb, and check the gutters for damage. If the metal of the gutter is ripped, warped, or torn, you'll want to replace that section of the gutter completely, a job best left to a contractor. If the hangers or spikes holding the section up have simply come loose, you'll just have to replace those.
Use the crow bar and hammer to carefully remove the old spikes from the roof. Take care to not use too much force, as you can damage the fascia or roof if you're too aggressive.
For gutter spikes, simply install them using the hammer. You can place the spikes in the holes where the old spikes were installed if they fit snugly, but if they won't support the gutters, find a new spot. Look for the heads of nails along the roofline, as this is where the rafters are. Hammering a spike into a rafter will provide a secure hold.
For gutter hangers, the same principles apply: use the drill to unscrew the screws holding the hangers in place, and then install the new hangers with new screws. Again, the same holes can be used if the hangers are able to sit tightly, but if not, look for nail heads along the roofline to find a rafter to screw into.
