Gutter Covers, Screens and Mesh

Gutter Screen Covered With Leaves and Pine Needles. Water overflowing past gutter

🚫 Debris Disrupts Water Flow – Leaves, pine needles, and pollen pile up on gutter screens and covers, forming a barrier that causes rainwater to flow over instead of flowing into your gutters.

💦 It’s Not a Defect—It’s the Design – Even professionally installed micro-mesh and screen guards get dirty and become a ramp sending the water past the gutter, especially in heavy rain.

😩 Expensive & Frustrating – Many homeowners invest thousands in gutter covers, only to find their gutters still overflow when debris builds up.

🔧 More Maintenance, Not Less – To keep screens working, regular cleaning is required, often meaning more time on a ladder—defeating the purpose of a gutter guard.

✅ GutterBrush is the Better Solution – Instead of covering gutters and trapping debris on top, GutterBrush fills the gutter, keeping water flowing while preventing gutter clogs and overflow—no screens, no frustration, just reliable protection.

The only thing that has worked!

My house is surrounded by trees...pines, oaks, maples. My gutters and downspouts clogged continually. I purchased gutter guards that fit atop the gutters, but the rain just slid across them and waterfalls down the other side. I purchased gutter brush a few years ago and I don't have to worry now. Everything flows smoothly. Yes, every now and then they need to be taken out and shaken to clean them, but it's been 3 years and they are still doing the job without me touching them. So simple, yet so effective.

Success for 2”alumawood gutter

I finally found something that’ll work for my 2 inch wide Alumawood patio gutter. There really isn’t anything else available for such a narrow gutter. Gutterbrush is the only company that offered a product that works!
Thank you, Gutterbrush.
