Debris accumulation is particularly problematic in gutters under a valley in the roof (e.g., where two differing slopes intersect) because the valleys tend to collect debris and drain it into the gutter below the valley, at a much higher rate.
When the debris accumulates in the guttering
system to the point that the guttering system can no longer adequately drain and direct the water away from the roof and away from the building, the water will inevitably overflow in and start to pour over the edge of the horizontal gutters and run down the sides of the building.
This can cause a number of serious problems.
For example, if a building has siding, the water can seep behind the siding, and leak into the building.
If such seepage is coupled with a severe drop in the outside temperature, i.e., the weather gets so cold that the water freezes, it can cause the siding to break up and or separate from the house.
Failure to replace the siding will cause further damage to the building.
It may even increase the building owner's liability due to tailing siding.
The replacement of the siding of a building is a large and expensive job which will either require an investment of a tremendous amount of time or the hiring of a carpenter or contractor.
The water can find its way into all the minute cracks and crevices, freeze with the drop of the outside temperature and expand, thereby causing the side of the building to break up.
Consequently even with
stucco or
brick, water spilling over from the guttering system will physically erode that surface at a much higher rate than it would if the water is properly diverted.
This in turn may compromise the building by leading to cracks in the building's
basement walls, and / or the building's foundation, and seeping into the lower part of the building itself.
Or alternatively, the water will not seep into the ground, but will stay on the surface where it can freeze and cover the whole area with a sheet of ice thereby making it very treacherous to walk anywhere in the immediate vicinity of the building.
Or even still, water may start to accumulate and become trapped on certain sections of the roof.
This may wear the roof down and eventually lead to a leak in the roof causing damage to the sections of the house protected by the roof.
Nothing provides for an advance notice or warning that debris has started to accumulated and beginning to block the flow of rainwater, or of an impending overflow.
It does so with either complex, multi-component apparatus that is costly difficult to install, and not user-friendly; or with cuplike, concave debris collecting screen structures, or
solid receptacles, that can be accessed either through
doors, apertures, or openings in the side walls of the devices themselves, or through the complete disassembly thereof.
Thus, generally speaking and on the most part, the only time that the users of the devices in the prior art will think of removing the debris is when the blockage actually occurs (this time from the very debris that has accumulated in the devices themselves), the rainwater backs tip, overflows over the edges of the horizontal sections of the gutter system along the
eaves of the roof, and spills and gushes all over the side walls of the buildings.
Repeated blockages of this sort, will cause the very problems that the prior art has been designed to avoid.
None of the prior art provides for a solution to the situation that arises if debris accumulates and clogs a section of the rainwater gutter system that is not accessible, as for example when debris is trapped in the upper section of the
downspout, close to the roof, high
above ground level.
