Make A Splashguard To Prevent Gutter Overflow
Yes, necessity is the mother of invention. I needed a splashguard for one of our roof gutters that was constantly overflowing (due to high water volumes) and could not find one anywhere, so I made one instead.
I’ll show you how I created the splashguard and installed it, all for under $10. It would have cost at least $150+ if I’d had an installer do it.
I’m always happy to find effective, frugal solutions to household problems.
How To Make A Splashguard
After mulling over several options, I realized the smartest thing to do is to make the splashguard from the same material the gutters are made from: aluminium. Plus it’s easy to cut and very lightweight.
If your gutters are newer, they might be plastic, in which case you’ll want to get yourself a scrap piece of aluminium downspout in a matching colour.
Materials & Tools

- Aluminium downspout (matching your existing gutters)
- GE II Silicone sealant for gutters and flashing
- (8) 1/2″ metal screws
- Tin Snips (for cutting metal)
- Electric drill and driver bit for the screws
- Safety glasses and protective gloves
- First inspect the location where you’ll be installing the splashguard. Get up there on the ladder (using all safety precautions), and see where you can screw the splashguard into the gutter lip.
- This project is really simple and you may find it easier to envision what you need rather than struggle through how I’m describing it! It’s really just an L-shape piece of aluminium, bent in the middle to form a 90° angle.
Here’s a top view of mine (I have leaf guards on top of the gutters):
- Cut out 24″ of downspout, first cutting next to seam on downspout, then around the circumference to end up with a 24″ piece of aluminium.
- Carefully flatten the piece of aluminium. It bends easily but it also dents easily.
- Press aluminium piece against the edge of a table, forming a 90° angle, with a 1″ lip. You’ll want the painted side of the aluminium facing out: the 1″ folded section will face inward. This is the part that will sit on top of the outer gutter edge.
- Now you’ll want to bend the splashguard to fit the angle where your gutter bends. My gutter is bent at a 90° angle, so I first cut out a small V-shaped notch in the middle of the 1″ lip, then folded the entire piece at 90°.
Now you’re ready to install it.
- Run a generous bead of GE II Silicone sealant along the underside of the 1″ bottom lip of the splashguard.
- Bring your drill, metal screws, and the splashguard up the ladder (safely!). Press the splashguard into place (on top of the gutter lip), matching the notched area to the bend in bend in the gutter first.
- Install the first metal screws at the bend, placing one on either side of the notch, and be sure you have a nice tight fit with no gaps where water could escape.
- Install the remaining screws, placing one at each end of the splashguard lip and one in each middle section, between the notches and the ends.
- Press to ensure the silicone sealant bonds the gutters and splashguard together. Wipe away any excess sealant on the outside (where it would be visible and annoy you).
Your splashguard should stay nicely in place just like mine does here. We’ve had several severe rain storms since I installed it and it works perfectly. All for less than $10. Woot!
