Flat roofs can be incorporated into residential and commercial buildings with different architectural designs. They are ideal for places that don’t experience huge quantities of moisture or rain on a regular basis. Apart from adding an aesthetic appeal, the roof should be durable and resistant to changing weather conditions to avoid damage. However, the most common problem faced by this type of roofing is drainage. Unlike other roofs that drain water automatically, a flat roof needs a specialized, built-in drainage system to get rid of debris and water. Failure to do so can result in popped nails, pulled-away flashing, gravel being washed away and exposed railheads. These can lead to further issues such as a leaking roof and damaged roof deck. To avoid these problems and increase the life of your building, read this blog post to find out about the best drainage systems for flat roofs.

Scuppers are one of the most effective drainage systems for flat roofs, allowing accumulated water to drain off properly. This system uses large square openings along the roof’s edges and allows water to run along the wall through a metal box that surrounds the scupper. You may choose to install a downspout directly below the openings to drain the water in a controlled manner.

This affordable drainage option can be incorporated into your existing system.

They are mainly found on structures with large roofs, and the drains are generally placed in the centre of the building. They may require the installation of copper or aluminum inserts in those areas where water most commonly collects to keep it from destroying the property. Some reasons why they might be a perfect fit for your home are:
3. Gutters
This is the most common drainage system, used for all types of roofing. They work by collecting rainwater and diverting it to a downspout which dispenses it at a distance from the building’s structure. They help prevent water from rolling off the building in an uncontrolled manner and running down the sides, resulting in damage to the foundation, siding and windows. You should consider installing gutters on your flat roof since they are:
These are three of the most common drainage systems for flat roofs. They offer the best solution for both commercial and residential buildings. Sadly, most property owners fail to realize the necessity of having a suitable drainage system to help prevent future damage from erosion, mould growth and insect infestations.
