Why Valor works
Valor's owner was tired of the complaints about gutter guards that were not working, so Valor built one that does. Other designs have flaws. They did not figure out that the water has to be slowed down, and that the guard has to sit at the angle of the roof.
Valor's patented S-turn design turns the water and slows it, so more of it goes into the gutter. The raised shape keeps debris from lying flat, and a light breeze carries it off.
Micro mesh used to have a bad name
Before about 2015 there was no micro mesh guard that worked well. Criticism of micro mesh from that era describes the older designs, not Valor.
