Flat roofs cause a notoriously large amount of problems when compared to a traditionally sloped roof. So what exactly is the appeal to begin with? Well, to start with, most “flat” roofs aren’t actually entirely flat. A majority of them are a low slope roof, in order to help water flow away from the center and to drains.
So what’s the big deal about flat roofs anyway? Flat roofs have always been more economical to construct, and because of the decreased ceiling height, a majority of flat roofed buildings have much lower heating and cooling cost than their high sloped counter parts. This along with the availability of the roof being a patio is quite the attraction. Many people create green roofs, with gardens and trees on their entire roof. Other people set up chairs and tables, games, TVs, Couches, above ground pools, you name it, it’s been on a flat roof.
Enough about why they are so great. Flat roofs are extremely notorious for leaks. Because it’s harder for water to drain on a lower slope, the water may have a tendency to sit longer, which over time can start to eat away at your roofing structure. Also, rain outlets tend to get clogged up from time to time and require regular maintenance and cleaning. When the drains get blocked up, you run the risk of flooding your roof. If you have barriers up on your roof, you are opening the door for a potential swimming pool above your head. Be sure you have someone who is assigned to checking up on your roof at the very least once a month. Prevention is the key to a successful flat roof.
