The mesh spec
Stainless, not aluminum or plastic. Stainless doesn't corrode in contact with the constant wet-dry cycle in a trough, and it doesn't go brittle under UV the way the plastic guards sold in the 90s did.
Openings are fine enough to stop pine needles, which is the test most guards fail. If a needle can find its way through, so can everything else that matters.
Mounting
Two methods. Under the first shingle course, which gives the cleanest line and the best water transition, or on a standalone bracket that doesn't touch the roof at all.
We use the bracket method on roofs near end of life. Lifting shingles on brittle old asphalt is how a gutter job becomes a roof leak.
What it doesn't solve
Ice dams. That's attic heat and ventilation, and no product on a gutter changes it.
Valleys. Where two roof planes meet, the concentrated flow can push debris into a pile on top of the mesh. It's still on top rather than in the trough, but it needs a look occasionally.
Shingle grit on a brand-new roof. The first year of a new asphalt roof sheds granules, and they can film the mesh. A rinse handles it.
Maintenance, realistically
A hose rinse every couple of years. That's it on most homes.
That's a genuine change from three ladder trips a year, but it isn't zero. Anyone telling you it's zero is selling.
Questions people ask
Does micro-mesh stop pine needles?
Yes. That's the main reason to choose it over screen guard in this metro.
Will water pass through in a heavy downpour?
Yes, if the mesh is clean and the gutter is pitched correctly. Micro-mesh handles downpours better than reverse-curve systems do.
Do I still need to clean my gutters?
A rinse of the mesh surface every few years, and a look at roof valleys. Not the trough.
Can it go on my existing gutters?
If they're sound and properly pitched, yes.
