Flat Roof Drain |
Reed's unfamiliarity with building design in general and roofs in particular is quickly exposed in her first paragraph:
"A flat roof is commonly used on many buildings, especially those that house businesses. Slanted roofs are typically only seen on homes, and are considered more of a decoration. However, a flat roof creates many challenges for the owner. The main problem is in the area of rainfall. Water has to run off of the roof to keep it from leaking down through the ceiling and into the building below. But while water can easily run off a slanted roof, a flat roof impedes the process. It is important to find a way to get rid of the water before it does any damage to the building."OK, nominally true though "those that house businesses" is rather simplistic: do you consider an apartment complex a "business"? Let's just say, "commercial buildings," Jessica... and then there's the construction of "a flat roof impedes the process"; a rather strange way to say what she means.
Reed then wastes a paragraph on "What can cause a flat roof to leak?" before getting to the meat of the matter, "How does water run off a flat roof?" That's where she explains that "several steps can be taken":
"First, consider having a coating applied that can help keep leaks from occurring. Adhesives are available that can help trap the water out. The main way water can run off a flat roof is through a drain system. Having drains and gutters installed correctly will direct the water into the drains, which will in turn let the water pour harmlessly onto the ground below. Water can also be drained by having the roof built up slightly, to allow it to drain better. A combination of these alternatives allows water to run easily off of the roof." |
