Question: Will this product clog up with pine needles and block the flow of water over time?
Document: As a contractor, I've had the opportunity to work with a number of different gutter filter systems, and this is definitely one of the easier ones to install. I like that it leaves a little channel along the lower inside edge of the gutter for water to flow through too. Corner miter cuts are easily done with a pair of snips, or a knife.
And I know that in 6-12 months this will degrade and make cleaning gutters even more difficult than before.Such a shame -- if they would just make the product bigger, or have a half-circle aluminum piece with many holes in it to let water thru, that sits underneath the product, which would raise the top of the product flush with the top of the gutter.
An adventure up the ladder during a heavy rainstorm showed that at the high end near the point of concentration, my gutter was completely filled to the brim and pouring over like a waterfall, while 20 feet away near the downspout, the water was less than 1" deep.My solution to open up more flow area, and so far it's working, is to cut the foam into an L shape using a utility knife. See the picture I've added. Don't cut the top part too thin or it will sag.
I live under a gigantic Sycamore. My first winter in the house, 3 years ago, saw me up a ladder at 3am removing a huge clog of leaves from the gutter outside the bedroom. I mean the sound of falling water is soothing and all, but not when it's a stream that sounds like an elephant reliving itself on a tennis court!After a ton of research, I decided to give GutterStuff a go.
It appears to be better quality and should last longer, but time will tell.
And again, this only needs to be done in those areas where there is a concentrated flow entering the gutter more than 10' or so from a downspout. Gusher Guards also help at valleys to keep heavy flows controlled.
Expensive mistake. Avoid this product.
In those situations, if there is debris, it can cause the heavier than typical flow to skim over the top. Keeping it clean in that area is all that's required to fix that. There's an additional problem when the point of concentration is too far upstream from the downspout. In my installation, there are two locations where the distance from concentrated flow to downspout is 20 feet or more.
this stuff is amazing, I have not had to clean my gutters since putting it in. Great product a little difficult to put in but does the job hands down
If your roof is mostly long slopes down to the gutter with no valleys or other places where flow is concentrated, this stuff works great, as-is. If you have valleys or downspouts that come down from upper levels with a concentrated flow, it can cause isolated overflow problems that require a little customization. What I found from having it in place for two years is that "sheet flow" into the gutters, even during heavy downpours, is drained away exactly as advertised.
Answer: no
