Benefits of Drainage for Commercial Flat Roofs

If you have a commercial business in Colorado, the odds are good that your building has a flat or low-slope roof. That’s primarily because a commercial flat roof is inexpensive to install, easy to maintain, provides a location for HVAC equipment, and it’s relatively versatile for most environments.

But there’s one big issue with them: commercial flat roof drainage.

Especially in Colorado where heavy snowfall happens overnight, a flat roof is susceptible to drainage problems, which can lead to ponding or standing water. Ponding is a sign of an underlying issue. Sometimes it happens because the roof drainage is blocked. It can also be caused because of a design or material issue. If you don’t take care of ponding water on your commercial roof by removing it in a timely manner, you might be at risk of serious damage.

Why Water Ponding Is Bad for Your Flat Roof

Because of their low slope, commercial roofs can easily accumulate water. This is not only bad for your roof, but it can also cause damage to your essential heating and cooling systems, the interior of your building from water leaks and mold, and even your building’s foundation if the situation becomes bad enough. And because water is heavy, large pools can add significant weight to your roof and building’s structure.

A general rule of thumb is that water on your roof should either evaporate or be drained away within 48 hours of appearance. If you notice ponding water lasting longer than that, you need to take action to prevent other damage to your roofing materials and your building.

Benefits of Commercial Flat Roof Drainage

1. Saves You From Severe Damage

Ponding water—whether it’s from rain, snow, hail, etc.—can soften your roofing materials and lead to cracks and leaks. Draining your commercial flat roof can prevent such issues from occurring and save your building from serious damage, including mold.

2. Extends the Life of Your Commercial Roof

The science is simple: the better maintained your roof is, the longer it will last. Properly draining your commercial roof is non-negotiable if you plan on keeping your roof in action for as long as possible. In particular, you should have your roof inspected after any significant weather event like a hail storm.

3. Protects Your Business From Preventable Closure for Repairs

The last thing you want for your customers is to have to close up shop because your building needs significant repairs. Properly draining your commercial roof—and taking care of commercial roof repairs as needed—can help you keep your business running smoothly and without unnecessary interruption.

4. Prevents Other Unexpected Damage

Water leaks and mold aren’t the only damage that you can experience if you don’t have your commercial roof drained in a timely manner.

Ponding water can soften your roof deck and make your flat roof dangerous to step on. It can also attract pests like mosquitoes and other animals that can cause preventable damage to your roof. For example, birds create a lot of mess, and they can contribute to plant and fungal growth on your roof, which can be difficult to remove.
