Question: will leaves accumulate on top of the gutter guard, and will it be necessary to clean them off?
Document: Leaf Relief is a rip off. It clogs up with leaves and they DO NOT blow off. We were looking to get away from cleaning the gutters but this just does NOT do the job. We still have to get up on a ladder and clean it out. Do not buy this product.
Matched Leaf Relief gutter guard purchased at a box store that no longer has it. We use it with a flat roof and all seed pods, etc. just wash right off.
I had "leaf Relief" installed in my gutters almost 6 yrs ago and still have not had a problem with them. Before we had them installed we had countless different types of leaf protection and non had worked. My partner and I where ready to throw in the towel and forget leaf protection all together, but when we hired a company to clean them out and throw the guard in the trash, they recommended "Leaf Relief" saying it would be our last time changing leaf guards.
I went back and spend $400, enough to do the whole house and by the end of the day I had it installed everywhere. 40 feet up on the roof was pretty scarry so it was important to me to only do this once. Now when I visit the vacation home I get out the ladder just to look at the top of the gutter and see how well they work. I am telling you stop looking and buy leaf relief; end of story.
I purchased this product to install it on the gutters on our house which are not already fitted out with some LeafRelief gutter guards I  had installed previously. However,  the style of the front edge and the color of the new ones are different from those earlier Leaf Relief gutter guards. That said, I plan to return them to Bluelinx and hope that I can received a refund.
I researched lots of gutter guards and was ready to buy the foam. So i Called my builder for my vacation house in the woods because I didn't know where I could get it 800 miles from my main home. He gave me the name of a local building supply house and when I called them they said they didn't sell the foam they sold something better. I thought sure, sell what you stock. So I bought 40 feed of Leaf Relief and installed it on the back of the house over the deck.
I must say this it was a bit pricey but well worth it simply because it actually works.
