Abstract
According to the invention there is provided a rain channel for protecting a roof from water flowing out of a downspout. The rain channel comprises a base formed by an elongated sheet of flat, water impervious material, and a pair of upstanding, spaced apart barrier tabs extending a length of the base.
Description
ROOF RAIN CHANNEL
FIELD:
The present invention relates to a channel or guide for preventing water which flows down a downspout from an upper roof from contacting a lower roof level as it drains to a gutter along a bottom edge of the roof.
BACKGROUND:
One major cause of deterioration of roofs covered by asphalt shingles is a hardy type of algae called Gloeocapsa Magma. This algae feeds on the crushed limestone that is used in asphalt shingles. Rain spreads the algae down the roof causing the black streaks which prevent the shingles from reflecting heat properly and causing them to fail prematurely. Even if one were to eliminate the algae, flowing water damages asphalt shingles in any event. When rain water hitting an upper roof level is collected by a gutter running along a lower edge of that roof and subsequently transported down to a lower level of an asphalt roof by a downspout, the water that flows out of the downspout to the gutter, results in algae spreading and build-up which damages the area of the asphalt roof over which the water flows and ultimately causes leaks.
Elimination of the downspout is not possible as the manufacturer will not warranty the shingles unless there is a downspout. One solution has been to use the downspout tube along the roof by attaching one end of it to a lower end of the downspout and positioning the other end over the gutter. However, having a relatively large tube running along one's roof is somewhat unsightly.
SUMMARY OF THE INVENTION
According to the invention there is provided a rain channel for protecting a roof from water flowing out of a downspout. The rain channel comprises a base formed by an elongated sheet of flat, water impervious material, and a pair of upstanding, spaced-apart barrier tabs extending a length of the base.
Preferably, the barrier tabs are spaced apart at least a width of the downspout wherein all of the water emanating from an open end of the downspout flows down the rain channel.
Advantageously, the base and tabs are formed from a single sheet of the flat material.
A height of the tabs is between a half-inch and an inch.
The tabs are formed by folding one section of material back on itself so that the resulting elongated tabs are perpendicular to the base and the rain channel is made of a single unitary piece of material.
A rain diverter is couplable to a discharge end of the rain channel and is operative to change a direction of flow of water flowing along the rain channel.
The rain diverter has a first roof portion and a second roof portion inclined at an acute angle with respect to the first roof portion.

The first and second roof portions are preferably flat and the walls of the second roof portion snugly, slidably engage the barrier tabs.
In another aspect of the invention there is provided a method of making a rain channel for positioning between a lower open end of a downspout and a gutter of a roof, comprising selecting a length of rigid foldable sheet material so that it spans a roof from an upstanding wall down a slope of said roof to an elongated gutter, and folding said material to form two spaced apart, upstanding, elongated barrier tabs along the length of the material.
The barrier tabs are spaced apart by at least a width of said downspout.
The sheet material may be a metal such as aluminum.
A rain diverter is couplable to a discharge end of the rain channel and is operative to change a direction of flow of water flowing along the rain channel.
The rain diverter has a first roof portion and a second roof portion inclined at an acute angle with respect to said first roof portion.
The walls of the second roof portion snugly, slidably engage the barrier tabs at an end of the rain channel and the first roof portion is inclined downwardly towards a trough of a gutter.

BRIEF DESCRIPTION OF THE DRAWINGS
Further features and advantages will be apparent from the following detailed description, given by way of example, of a preferred embodiment taken in conjunction with the accompanying drawings, wherein:
Fig. 1 is a perspective view of the rain channel;
Fig. 2 is a perspective view of a portion of the multi-level asphaltic roof with the rain channel in place;
Fig. 3 is a perspective view of a rain channel installation with a rain diverter; and Fig. 4 is a rain diverter.
DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWINGS
Referring to Fig. 1 the rain channel 10 is an elongated base 12 of flat sheet material formed with two upstanding, spaced-apart barrier tabs 14 along respective side flanges 16. The rain channel 10 is made from a single sheet of material that is folded over onto itself to make the two upstanding barrier tabs 14 in order avoid the greater risk of leaks if the rain guard were made of two or more pieces welded together.
Ordinarily the rain channel 10 is made of the same material from which the gutters are made, namely, tin, aluminum or plastic. Roof shingles made of asphalt or wood are vulnerable to water damage by streams of water flowing over top of them into a gutter positioned around a lower perimeter of a roof.

The rain channel 10 is made from a single sheet of material that is folded over onto itself to make the two upstanding barrier tabs 14 in order avoid the greater risk of leaks if the rain guard were made of two or more pieces welded together.
Ordinarily the rain channel 10 is made of the same material from which the gutters are made, namely, tin, aluminum or plastic. Roof shingles made of asphalt or wood are vulnerable to water damage by streams of water flowing over top of them into a gutter positioned around a lower perimeter of a roof.
As seen in Fig. 2, the rain channel 10 is employed by placing one end beneath an open bottom end 24 of a downspout 18. The downspout 18 is held against a vertical wall 22 of a residential building by straps 20. The other end is positioned over an open trough 28 of a gutter 26. Water flowing down the downspout 18 enters the channel between the two barriers 14 and flows down the channel into the gutter 26. The water does not come into contact with the asphalt shingles of the roof 30 and so cannot damage the asphalt shingles. The rain channel 10 may be fastened to the roof shingles by applying a bead of silicone along an underside of the flat surface of the elongated base 12.
Referring to Figs. 3 and 4, in order to prevent water which flows down the rain channel 10 from splashing over the gutter 26 or flowirig out of the other side of the gutter 26, a rain diverter 16 is used to change the direction of flow of the water so that it is re-directed down into the trough 28 of the gutter 26. Rain diverter 16 has two outstanding spaced apart elongated walls 25 of a spacing slightly less than the spacing of barriers 14. The walls 25 of the rain diverter 16 enclose a flat first roof portion 30 and walls 27 encloses a second flat roof portion 32 inclined approximately 45 degrees to the first roof portion 25.
As seen in Figure 3, the walls 27 of the second roof portion 27 form a tight slidable friction fit between barriers 14 at the lower end of the rain channel 10 leaving an open passageway (not seen) from roof portion 32 to roof portion 30.
