How to Prevent Water Damage on a Flat Roof
Commercial buildings commonly feature flat roofs. These roofs include maintenance challenges, such as standing or pooling water after rainfall or melting snow. A roof with a proper drainage system will get rid of excess water immediately. Otherwise, the standing water can damage the roof and lead to more costly repairs for the building owner. Learn more about how to prevent standing water and water damage on a flat roof.
Signs of Drainage Issues
To avoid dealing with standing water issues on your flat roof, you should be aware of the signs of a roof drainage problem ahead of time. A flat roof will manifest its drainage issues through the following signs:
- Water leaks
- Water puddles or pooling
- Mold growth
- Wood or other material warping
If during regular inspections of the roof you notice any of these signs, it is important to address them as soon as possible to avoid further damage to the structural integrity of your building.

Fix the Dips
Despite the name, flat roofs are not entirely flat. They usually include a very subtle slope that is part of the drainage system. However, water can create small low spots in the roof, or dips that retain the water instead of letting it roll off the slope. A commercial roofing specialist can fill these spaces with roof plaster to increase drainage effectiveness.
Re-Pitch Your Roof
Pitching is another term for the slope in the flat roof. Improper pitching allows water to gather on the roof. You may need to consider investing in a re-pitching procedure for your flat roof, preferably handled by a trained roofing technician.
Unclog Your Drains
The slope in your flat roof usually leads the water to existing drains, such as rain gutters and downspouts, to clear the roof. Water sometimes carries debris like branches, sticks, and leaves, which can block the drains and allow water to accumulate on the roof. Simply unclog the drains from debris and garbage to allow more water to flow away from the roof. Inspect the drains regularly to spot and prevent blockage.
Add or Modify Drains
Sometimes your roof lacks enough drains to get rid of the water at a reasonable rate, or the drains may be too small to handle the large amounts of precipitation adequately. Hire a roofing contractor to either install additional drains or expand the size of existing ones to increase the amount of water they can displace away from the roof.
Replace the Roof
Even with a proper drainage system and excellent maintenance, an older roof will eventually need repairs or complete replacement. If your roof is more than 10 years old, seek the advice of a professional roof technician to evaluate the integrity of your flat roof.
