Having worked as a sales rep for Leaf Filter myself, let me say that I feel your pain. You have to get up there and clean them off or wait for a strong wind which is not likely to remove all debris up there. You can of course opt to call them up and demand that they take care of it since you do have a lifetime guarantee. I quit Leaf Filter as a salesman because I eventually realized that the company grossly overprices their product and makes claims that, in the real world, are simply not true. Leaf Filter wants to charge customers $30 a foot for their gutter protection while you can actually get something equally as good if not better for less that $3 a foot!  Here's an example: https://www.homedepot.com/p/Gutter-Guard-by-Gutterglove-4-ft-L-x-5-in-W-Stainless-Steel-Micro-Mesh-Gutter-Guard-10-Pack-THD40/300252780?
