Rosa A. Ostergaard Gutter Guards July 13th, 2018 - 07:42:50
Water will follow the contour and run downward into what would be the gutter. But what would happen it you place some wet leaves on top of the gutter cover?. If you dont have leaves use a dollar bill as it will mimic a wet leaf and will move slowly to the fin and instead of dropping off the fin watch it follow the fin downward with the water into what would be the gutter. Youll notice that this type of gutter guard will pass full sized leaves along with most of the tiny buds and blossoms in the spring time. No doubt about the fin type of gutter being self cleaning.
This gutter guard is the only rounded nose type that limits the amount of debris or size of debris that can pass into the gutter. This one system has proved that gutters can stay free flowing in heavy debris conditions for twenty years; and thats no small feat. The only downside is that in heavy debris conditions debris can accumulate on the louvers and block them off meaning that some kind of maintenance is required. Whereas most other products require someone to go up a ladder and clean the gutter or the cover it can easily be done from the ground using a telescopic pole and brush. Because its easy to see where cleaning is required theres no guessing where to do the brushing. No rain coats are required (as might be with the flip type gutter) to do this simple task as it can actually be done dressed in a suit and tie. After all telling someone who has to clean his gutters several times during the fall that no maintenance will be required is like asking the him to believe in Santa Claus.
Next are the gutter guards with solid tops and a rounded front nose or fin. The water flows down the front nose through a space about 3/8" width into the gutter. You would think that the water would just skip off the gutter cover onto the ground but no. It is actually directed into the gutter as it sticks to the surface of the leaf guard. After experience with screens and filters it makes sense to doubt the ability of these devices to make gutters self cleaning and rightly so. Go to your kitchen sink and run water over a small section of the gutter cover.
There are commercial products that attach the downspout end that rolls out when water in the leader puts enough pressure on the inside of the roll. The plastic roll has holes to act like a sprinkler hose thereby letting the water out slowly causing no damage to plants or lawns below. There are many types of after market gutter accessories to prevent leaves and other debris from entering the gutters and clogging them. Gutters must be cleaned at least once a year to prevent debris from clogging the downspouts and causing gutter overflows.
