Clogged Roof Head Drains in Commercial Buildings

Dealing with clogged roof head drains is a significant concern for industrial and commercial building owners. Accumulation of debris, including leaves, twigs, and garbage, on the roof can lead to clogs in these drains. Over time, such blockages can damage the roofing materials and create hazards like water pooling and unwanted plant growth.

The Consequences of Neglecting Roof Head Drains:
Clogged roof head drains pose various problems, such as:

  • Deterioration of Roofing Materials: Damage to caulk, cement, and tar due to prolonged exposure to stagnant water.
  • Water Seepage Issues: Pooling of water around HVAC components and chimneys can lead to structural damage.
  • Damage from Freeze and Thaw Cycles: Water seeping into cracks can cause significant damage during freeze-thaw cycles.
  • Structural Strain: Accumulated water adds weight, straining the roof’s structural supports.
  • Plant and Algae Growth: Unchecked, stagnant water encourages the growth of plants, moss, and algae.
  • Formation of Ice Patches: Water accumulation can freeze, creating hazardous ice patches.
  • Mosquito Breeding Grounds: Standing water on roofs can attract mosquitoes, creating health hazards.

Preventative Measures for Roof Head Drains: Regular maintenance is key to preventing clogged roof head drains. Here’s what you can do:

  • Monthly Inspections: Conduct a thorough inspection of roof head drains at least once a month.
  • Debris Removal: After storms or windy days, remove tree branches, leaves, and other debris from the roof.
  • Proper Equipment: Ensure you’re using the right size of drain domes to prevent clogs. Larger domes are less likely to clog but require larger piping.
  • Avoid Harsh Chemicals: Use a garden hose to clear drains, avoiding chemicals that can damage pipes.
