Drainage is crucial for commercial buildings, and it helps direct water off the surface of their flat roofs. Since most commercial buildings have flat roofs, their drainage systems are a bit more complex than those of a residential home. So when these systems are clogged or interrupted, they require the attention of a professional for emergency roof repair in Toronto. Given the sheer size of commercial buildings, clogs can build up in a matter of hours. Without swift treatment, clogs can escalate, damage your roofing materials, and lead to leaks and water damage. If you notice water pooling on your roof, contact a reputable roofing company in Toronto, like King Koating. Call us today to book an appointment.


Understanding Commercial Roof Drainage Systems

Not all commercial roofs are built the same in terms of their drainage system; however, each one likely has standard gutters, downspouts, scuppers, and internal drains. Some roofs also have siphoning systems that help pull out excess water. Your gutters are what catch and direct water through the downspout, which drains at ground level. Scuppers, on the other hand, are larger openings that allow water to fall directly off the roof. 


Common Drainage Issues in Commercial Roofs


Drainage issues on commercial roofs require immediate emergency roof repair in Toronto. Leaving drainage issues untreated can result in water pooling on the surface of your roof, and over time, it can cause irreparable damage. Some common causes of drainage issues include:


  • Leaves: Depending on the time of year, foliage, or other organic materials can get caught in your gutters, blocking the flow of water off of the surface of the roof. 

  • Improper Slope: Not all roofs are built the same, and some may not be angled enough to support effective drainage. Roof degradation can also contribute to an improper slope.

  • Scupper Blockage: Your roof scuppers can get blocked by ice, snow, large accumulations of foliage, and more. 


How Drainage Problems Escalate Into Urgent Repairs


Depending on the composition of your commercial roof, water can begin to deteriorate the surface of it either through penetration or erosion. If water does manage to damage your roof to the point where it cracks or there is an opening, water can actually enter your building and leak inside. This can lead to water damaging the structure of your building, including drywall, metal pipes, and wooden beams. Without treatment, this can also lead to mold growth. 


The best course of action when it comes to commercial roofing is immediate repairs, as this can help prevent minor roof damage from escalating.
