Here's a gem.
The guy who did the video taping did this after just one year of service and I have no reason to doubt that period of time. What the video demonstrates is that tree debris can be a real mess.
I love all the videos you see of brand new gutter guards or leaf guards on a clean roof and new gutter with water being circulated over the gutter protector. The videos make so much sense until you realize the nature of leaf debris. Leaf debris is not like coffee grounds as the filter gutter guards would have you believe. It deteriorates and becomes a crust that adhere to anything whether it be made of aluminum, plastic, or stainless steel. And this crust is impenetrable by water. The video below shows how the crust accumulates on the fin type of gutter guard.
In fact a crust will accumulate on all types of gutter guards--even the Waterloov gutter system. The difference is in how they are cleaned or serviced. With the single fin example the fellow is cleaning it with a stick. But he might have--I say might have because a brush has to go deep into the fin and that might not be possible--been able to clean it from the ground with a pole and brush if he had the Waterloov System. The best time to do this is just after it has rained and the crust is moist. Look at the video and see for yourself.
The big difference is that by brushing the single fin type, all that gunk would go into the gutter causing it to clog whereas with the Waterloov system, the gunk is knocked away from the gutter guard by the stiff bristles of the brush being released by the louvers as the brush is moved across the louvers--nothing gets inside.
In the video below the gutters are located directly under a canopy of a dogwood tree and generally get brushed only once every two years or so.
Again, our competition is our best advertisement for when Debris meets its Waterloov, the war of clogged downspouts is over!
I'm sold!
