Flat low Slope Roofing

With more attention being paid to home energy efficiency and lowering our carbon footprint, flat/low slope roofing is becoming more common. A flat roof is one where the sloping roof surface is steeper than the surrounding roof surface. While flat roofs are certainly an attractive feature for homes they can present a number of challenges and considerations for homeowners. Not only do flat roofs present additional challenges for homeowners as they can be easily damaged, but they also pose certain environmental concerns. Here are some ways Flat low slope roofing can resist common roof problems.


As any homeowner knows rainwater that falls on a roof is just going to run off. However, the water that makes it to the surface has nowhere else to go unless it drains off the roof. Low slope roofs are ideal for this concept as the runoff travels along the roof in smaller particles and then picks up water from deeper levels of the roofing structure before exiting at the lowest point possible.

Failure To Drain

Even if rainwater makes it to the surface and then drains off the roof, there will still be water left behind. If there isn’t any water drainage, there will be pools of stagnant water which poses a health risk. In addition, stagnant water can create the perfect environment for mold growth and other types of microbial issues. Additionally, stagnant water can attract pests such as rodents and insects which ultimately cause damage to the interior of your home as well as to personal property.    

Poor roof construction

Flat roofs don’t have a support system within the pitch to provide additional runoff. Therefore your roof has to rely on gravity to move the water away from the foundation. While this may work well during the day, when the sun is shining, it becomes problematic at night when it is exposed to winter winds. durable


The lack of proper drainage along with the lack of proper protection on the pitched roof causes leaks to occur. Depending on the type of roof you have, leaks can be found anywhere from the flashings to the rafters. If water gets into these spaces, it can create unhealthy mold growth which can grow rapidly and make the air in your home smell musty or even worse – result in illness.
