Standing Water Can Create a Major Problem on a Flat Roof

Flat roofs are an economical and convenient option for commercial properties. Besides being cost-effective, they provide added space for HVAC units, rooftop gardens or other functional spaces. Moreover, standing water is a common concern for these roofing systems. They can cause significant issues to your building if not addressed promptly. 

Here’s what standing water can do to a flat roof. 

Why Is Standing Water a Concern for Flat Roofs?

Weakened Structure

The design of flat roofs doesn’t naturally encourage precipitation runoff as sloped systems do. Without an efficient drainage system, ponding water can occur whenever it rains. Prolonged water exposure can compromise a flat roof’s structural integrity. Your flat roof could also develop cracks or sag due to the weight of water. 

Material Degradation

Over time, standing water can weaken roofing materials and components, increasing the likelihood of leaks and moisture-related issues inside your building. While durable, asphalt and concrete are not immune to the effects of constant water exposure. The consequences of standing water aren’t readily apparent until significant damage has occurred, highlighting the importance of routine maintenance. 

What Can You Do About This Issue?

Ensure Proper Drainage 

Adequate drainage is vital to a long-lasting flat roofing system. Adding more drains or reconfiguring existing drainage might be necessary to move water off your roof more effectively. Regular maintenance is also essential to keep these drains debris-free.

Implement a Slope

Roof sloping can aid in water runoff. Although it may sound counterintuitive for a flat roof, it’s possible to introduce a slight pitch to the system without altering its aesthetic or functionality. This strategy can be especially beneficial in places where it often rains heavily.

Install a Waterproof Membrane

A robust waterproof membrane can provide extra protection against standing water. Modern waterproofing materials can withstand extended water exposure, reducing the likelihood of leaks and structural damage.  

Schedule Routine Inspections and Maintenance

Regular maintenance and professional inspections are vital to preventing various roofing issues, including ponding water. They allow experts to identify and fix problems before they require costly repairs, saving time, money and hassle in the long run.
