When it comes to commercial roofing, Commercial low-sloped Roofing systems are a popular choice throughout Wyoming. They’re cost-effective, easy to maintain, and offer valuable rooftop space for things like HVAC units, solar panels, or even green roofs. But while these roofs offer practical benefits, there’s one critical factor that often gets overlooked—proper water drainage.
At Pete’s Builders, we’ve seen firsthand how poor drainage on low-sloped commercial roofs can turn a simple issue into a costly disaster. Whether you’re managing a retail building in Cheyenne or a warehouse in Casper, this guide will show you why proper roof drainage isn’t optional—it’s essential.
What You Need to Know About Poor Roof Drainage
Unlike steep residential roofs that naturally shed water, commercial low-slope roofs are more prone to water accumulation. Without proper drainage systems, rain and snowmelt can pool on the surface, leading to a variety of problems.
You might be thinking, “It’s just a little water—how bad can it be?”
The answer: very bad, if left unchecked.
The Dangers of Pooling Water
When water sits on your roof for more than 48 hours (called “ponding”), it starts to do serious damage:
- Structural Stress: Pooling water adds weight to the roof system, straining your building’s structure and supports.
- Membrane Damage & Leaks: Standing water slowly wears down roofing membranes, making it easier for moisture to enter.
- Interior Damage: Water infiltration can lead to mold, mildew, and rot inside ceilings, walls, and insulation.
- HVAC Damage: Rooftop units are vulnerable to water corrosion and electrical short-circuits.
- Code Violations: Building inspectors in cities like Cheyenne and Laramie may flag persistent ponding water as a roofing system failure.
At Pete’s Builders, we’ve repaired countless roofs that could’ve lasted longer—if only they had the right drainage.
The Benefits of Commercial Low-Sloped Roofing:
🔧 It Can Prevent Severe Damage
Wyoming is no stranger to heavy snow, and all that snow eventually melts. Proper drainage systems ensure that meltwater moves away from the roof efficiently, preventing ponding, leaks, and long-term damage.
🧱 It Can Extend the Life of Your Commercial Roof
A well-installed commercial roof in Wyoming should last 20–30 years. Without drainage, you may be looking at costly replacement in just 5–7 years.
Regular inspections—especially after hail, snowstorms, or extreme winds—can catch minor drainage issues before they become major headaches.
🏢 It Keeps Your Business Open
Downtime equals lost revenue. Water damage that forces you to shut down for repairs affects employees, customers, and profits. A properly drained roof keeps your business running, rain or shine.
🦟 It Prevents Other Unexpected Issues
Standing water becomes a breeding ground for mosquitoes, birds, and pests. It also encourages the growth of moss, algae, and fungus, which deteriorate roofing materials over time.
Even worse—dried moss becomes a fire hazard during Wyoming’s hot, dry summers.
