How to Select the Best Drainage System for Your Flat Roof

Gutters and eavestroughs in EdmontonFlat roofs are popular in commercial construction and can be found on many homes and condos as well. Though there are numerous benefits to flat roofing, one of the main challenges is in settling on a proper drainage system. A. Clark Roofing & Siding LP., one of the most trusted Edmonton roofing companies providing residential and commercial flat roofing systems, is often approached by home and business owners who want to know more about drainage systems for flat roofing. We’ve put together a handy guide that can help you decide on the right system for your needs.

The Pros and Cons of Gutters

Just like most types of roofing systems, flat roofs can make use of gutters to drain away excess water. Open pipes running along the edges of the roof, gutters provide a cost-effective method for carrying water away from a building’s roof, sides, and foundation. They are good at dealing with just about any amount of rain and snow.

In order to be effective, however, gutters need to be cleaned on a regular basis. When blocked with debris such as leaves and twigs, gutters can cause water to pool and ice dams to form in the winter.

The Pros and Cons of Drains

Flat roofs can also drain water via a system of drains located at certain points on the roof, generally towards the centre. These drains – which will often be covered by a strainer to keep out debris – connect to gutters and pipes inside of the roof. As the pipes are protected inside of the building, they do not freeze during the winter and hardly ever need to be replaced. Plus, because it is hidden, a drainage system is also the most aesthetically pleasing solution.

The only downside is that drains tend to be the most expensive system to install. They can also become clogged if the proper strainers are not in place.

The Pros and Cons of Scuppers

If you’re really looking for value, then consider scuppers. Scuppers are essentially a series of outlets placed along the roof’s edge. Water drains through these outlets and into downspouts which direct it away from the building’s walls and foundation. Scuppers require almost no maintenance and rarely become clogged.

For scuppers to work well, however, the roof does need to have a sloped structure which can direct water to the edges. They are not generally the best option for handling snowmelt, but they are highly effective for heavy rain.
