Add-on protection

Gutter guards.

Professional-grade micro-mesh and reverse-curve systems — not the snap-in screens sold at hardware stores. Sized to your gutter profile, your roof pitch, and the trees actually overhanging your house, guards cut cleanings down to once a year or less.

Why guards

Less cleaning, without trading in performance.

  • Cuts cleanings from twice a year down to once a year or less.
  • Micro-mesh apertures block pine needles and fine debris while passing full water volume.
  • Stainless steel mesh won't rust, discolor, or sag over time.
  • Cut and fastened to your exact gutter profile — not a universal snap-in strip.
When they're not the answer

We'll tell you. Honestly.

  • Gutters already failing — rotted hangers, poor slope — guards extend the failure, they don't fix it.
  • Heavy oak or sycamore leaf load can overwhelm reverse-curve systems in the hardest storms.
  • Homes with minimal tree cover may not need guards at all — ask before you buy.

Micro-mesh vs. reverse-curve.

We spec the system that matches your trees and roof pitch — not the one with the higher margin. Both are available with your online quote.

Micro-Mesh

Best for: Pine, palm, and fine debris

A fine stainless screen fastened flush across the top of the gutter. Water passes through; even small debris like pine needles and palm fiber stays out. The right default for most LA homes.

Material: Stainless steel mesh, aluminum frame
Opening: ~50-micron openings

Reverse-Curve

Best for: Oak, sycamore, and heavy leaf load

Uses surface tension to pull water around a curved nose and into the gutter while leaves and larger debris fall off the front edge. Sheds heavy leaf loads well but can overflow in the hardest winter storms.

Material: Solid aluminum, baked-on finish
Opening: Surface-tension nose (no mesh)

Gutter guard product FAQ

In most cases, yes. Micro-mesh and reverse-curve guards are cut and fastened to fit your existing gutter profile — K-style, half-round, or box — whether Coastline installed the gutters or another contractor did. The condition of the existing system matters more than who installed it; sound hangers and proper slope are what make adding a guard worthwhile.
