Roof Drains-Two Systems to Protect Your Home
|
Two systems make use of gutters and downspouts, no matter which material they are made of. You can choose one of these roof drain systems based on which one fits your needs best. System OneThis is the traditional and cheaper method of roof drain systems. The gutters are firmly attached to the eaves and/or rakes. The runoff rainwater collected by the gutters is moved to the downspouts, which end above ground over a splash block of plastic or concrete. Since this system does not move water very far from the foundation, it is best used in areas that are not on a low, wet lot and have a soil that drains very well. If you decide to use this system, either plastic or concrete splash blocks will do. However, for the splash block to work, it must be turned so that it directs water flow away from the foundation. They must be used only in areas with exceptional drainage, and they must be maintained frequently to prevent blockage or accidental misplacement. System TwoThis roof drain system is the same as the first in that the gutters and downspouts work the same way. However, the downspout in this roof drain system will not end above ground. At the end of the downspout, a trench is dug at a downward slope away from the foundation. The trench should end no less than 8 feet from the foundation. At the end of the trench, a hole called a "French drain" is dug no less than one cubic yard in size. The trench should be lengthened and/or the French drain enlarged if the house is on a wet lot, the soil drains poorly, or a great amount of rainwater has to be moved. Once the hole is dug at the end of the trench, it is lined with a filter cloth and gravel that begins quite large becoming smaller as the layers are added. Drain tile is then attached to the downspout and run through the trench to the French drain. A top layer of filter cloth is placed over it all, and the dirt and sod are replaced. In both systems you should keep the gutters clean to promote open flow of water. To help keep the gutters free of debris, trim back trees that overhang the roof. You can also add a guard system made of plastic or metal mesh, which will keep debris from falling into the gutters. Otherwise, you need to manually clear the gutters of debris at least twice a year; maybe more if you have many trees. A good roof drain system is essential to keep your roof decking sound. It can also protect your siding and exterior walls from discoloration and rot due to prolonged exposure to direct moisture. Based on your particular drainage needs, you can choose the above ground roof drain system or the below ground system.
