After putting on a new roof, and new gutters we had 2 places where the gutters overflowed. Both as we can up the stairs to the deck. Not only was the water getting us wet, but it was soaking in around the foundation.
I'm a 67 year old woman. So if I can install this, you can. 2 screws, and it works seamlessly with our leaf screens. I did caulk around it just because I didn't want to come back and do it later if needed.
No more getting drenched, no more water around the foundation.
These are the only diverters I was able to find on the internet. Get them.
