One way to improve your home and increase its value is to install a roof drain system. While rain can be allowed to simply flow off of your roof onto your lawn, it is more beneficial if you have a roof drain to direct water away from your home. Roof drain installation can be a time consuming project, but it is also a project that you can accomplish yourself.
Without roof drainage, rain water can accumulate on your roof, damaging the roof’s structure and eventually causing leaks. When you install roof drain, this rainwater is directed to other sources. Some roof drainage systems even allow you to extend the pipes beneath the ground so that water does not flood your lawn.
The cost and time it takes to complete your roof drain project will depend on several factors. These include the size and shape of your roof, as well as the amount of rainfall you experience in your region each year.
Zurn Roof Drain
The Zurn roof drain is one of the oldest drainage systems available on the market. Established at the beginning of the 20th century, Zurn offers several types of roof drainage for almost any roof. Their distinguishing feature is that they are suppliers of drains made of several different types of material, including plastic for above ground pipes and iron for pipe extensions that reach below the ground. They are also famous for the backflow valve, one of the most valuable contributions to drainage systems.
Mesa Roof Drain
Like the Zurn drain, the Mesa drain is another revolutionizing construction style in roof drainage systems. These drains are constructed partially with rubber. The rubber structure of the drain allows it to be flexible-a quality that is necessary for homeowners with “floating roofs”. Floating roofs often slope towards the center of the roof where a grating is usually located. The grating is attached to the mesa drain and water is directed away from the home.
Siphonic Roof Drain
One of the newest and most hi-tech roof drain systems available today is the siphonic roof drain. The idea of this drain is to increase the rate at which rain flows from the roof as well as decrease the amount of air that is allowed in the pipes. The method in which the siphonic system drains water is similar to that of a vacuum.
The way this is accomplished is by way of an air baffle. The air baffle is the only significant differentiating feature; other than this addition, the siphonic drain is similar in appearance to other more traditional drains. As water passes over the air baffle, it is pushed into the pipes, reducing the amount of air within the pipe and therefore increasing the drain speed.
Because of this hi-tech design, the siphonic roof drain can be considerably more expensive than other drainage options. However, these drains are the most efficient, and do not require as much repair as other drainage systems. And because of the increased drain speed, they can cover more area than standard drains.
Flat Roof Drain
Some type of roof drain system is imperative if your home is equipped with a flat roof. Because there is little or no slope to these roofs, the homeowner runs a large risk of leaks and roof damage if he or she does not install a roof drain. Fortunately, most roof drain and plumbing companies offer several inexpensive drainage options for flat roofs, most of which you can assemble yourself.
Flat roof drains are usually built with rain gutters that are installed around the perimeter of the roof. These gutters are like long pipes that capture water and lead it to a vertical pipe that runs toward the ground. The gutters are placed at an incline and so that they can lead the water towards the vertical pipe quickly. Some are equipped with roof drain covers to prevent foreign objects from getting clogged in the pipes.
