Why Flat Roof Drainage Is Important

Allowing water to pool on a roof is a recipe for water damage, both on your roof and in your attic. Over time, standing water may break down waterproofing barriers or soak through sealant materials. The weight of standing water on a flat roof can also contribute to structural damage, either bowing the roof inward or collapsing roof sections. 

Installing flat roof drainage systems prevents water pooling after snow or heavy rain, helping water flow away to reduce the damage these elements do to rooftops. 

Top 4 Flat Roof Drainage Options

What options do property owners have for proper flat roof drainage systems?

#1: Gutters

Many residential and commercial properties rely on gutter systems to drain water away from rooftops. While most assume that gutters only work for pitched or domed rooftops, these drainage systems actually do the trick for roofs of all types. 

Flat roofs have slight slopes or grades that allow water to travel to targeted drains or other locations. Cost-effective, easily maintained and repaired, gutters provide a durable and budget-friendly option for property owners from all walks of life. 

#2: Internal Drains

Internal drains work best for new construction roofs. These drains rely on specific tilts and drain placements to draw water from rain or snow melt to the center of the roof. A series of pipes and gutters then carry the water through the building and away. 

You can’t see these internal drain systems from the ground, so they don’t disrupt the building’s appearance. 

#3: Scuppers

Scuppers work like gutters, except they don’t run the length of your building. Scuppers are one of the most effective drainage options for flat roofs and keep water off siding and window eaves as well. 

#4: Sloped or Tapered Insulation 

Another option ideal for new construction roofs, tapered insulation requires precutting to exact measurements. During roof installation, roofers create a slope that uses gravity to expel the water from the rooftop. 

Tapered insulation requires significant upfront investment and may work best for those with considerable construction budgets.
