Proper Drainage is the Key to Flat Roof Health and Optimal Performance

Proper Roof Drainage Can Prevent Leaks and Extend the Lifespan of the Roof

Flat Roof DrainageWhen people entering or walking through a shopping mall, big-box department store, or office complex lobby see water dripping into large pails strategically located around the floor, it would likely lead to an immediate conclusion that the building has a leaky roof. Certainly, such a display is not done for ambience, but it can have the opposite effect of driving shoppers or clients away from that business until any roof repair work gets done.

Although the individual businesses may vary in terms of their products or services, there is one common feature among these commercial properties; they usually have flat roofs. While somewhat easier and less expensive to install than a sloped roof, at least from the standpoint of labour, flat roofs have been known to leak; this is not only inherent in their design but can often be due to poor installation and/or a lack of maintenance, especially in relation to the roof drainage system.

It is important to note that a flat roof should not be perfectly flat; it should have a slight slope toward either an interior or perimeter drainage system. However, proper drainage can be affected by several factors, with the most common consisting of:

  • Poor design and/or installation – no slope
  • Areas of structural sagging post-installation
  • Inadequate number of drains for the roof area
  • Drains placed incorrectly or that become blocked

Signs that roof drainage might be ineffective would include one or more of the following:

  • Areas of ponding or standing water up to 48 hours after a rainstorm
  • Dry, dirt-filled spots (there was ponding water but it has evaporated)
  • Evidence of algae formation or vegetation growth in the dirt-filled areas

Consequently, if rain or melted snow is allowed to collect and stand on a flat roof without isolating the cause and resolving the matter, it can have serious implications, including:

  • A leaky roof
  • Loss of business
  • Structural damage
  • Reduced lifespan of the roof
  • Extensive repair work and costs

Therefore, in order to avoid any such repercussions, and to protect the health, longevity, and optimal performance of their flat roof, commercial property owners and/or managers must ensure that the roof drainage system is correctly installed and suitably maintained.

This can be achieved through a comprehensive roof inspection, particularly if there is any evidence of ponding water and/or a roof leak, as well as all associated repairs by the flat roof specialists at Avenue Road Roofing in Toronto.
