Industrial and commercial roofs catch a lot of debris. This includes items like leaves, twigs, garbage, plastic bags or anything blowing in the wind. Fortunately, roof drains come with a dome/cover to allow water to pass through while catching the debris. Over time roof drains can clog, degrade and even break. Allowing large debris and organic material to pass into the drainage system and cause problems.

What Can Happen If a Roof Drain Clogs?

A waterlogged roof can lead to some major headaches. All drains need to be functional to ensure the safety and reliability of your roof. If a roof drain clogs, water will start to pool and cause damage. Water pooling can:

  • Deteriorate roofing materials, caulk, cement, and tar.
  • Seep into and pool around HVAC components and chimneys.
  • Force extra water into cracks and crevasses, which causes damage during the freeze and thaw cycle.
  • Create additional weight from the water that will strain the structural supports of the roof.
  • Increase unwanted plants, moss and produce slime around roof decks and drains.
  • Create dangerous ice patches on the roof.
  • Create a large mosquito farm.

How To Avoid Clogged Roof Drains

The easiest recommendation is to regularly clean and inspect your roof drains. At a minimum, an inspection should be done once per month. Clean the dome/cover and brush away any built-up material around it. Use a garden hose and force freshwater into the drain. Avoid using drain cleaner or harsh chemicals, it can eat into the pipes and cause a bigger problem.

Habitually clean debris and organic material that's on the roof deck. Especially after a large storm or extremely windy day. Tree branches, leaves, and other materials should be removed from the roof.

Use the right equipment. Drain domes come in a lot of different shapes and sizes. Larger domes allow more debris, smaller domes are more restrictive. Bigger domes typically connect to larger piping, so it won't lead to notable clogging. If you notice constant clogging, you may be using the wrong equipment.
