If it feels like it’s been raining nonstop in Colorado—you’re not imagining things. This year, our state has already logged over one-third of its annual precipitation, putting us ahead of Seattle for rainfall totals. While the green lawns and cooler temperatures have been a nice change, this record-setting moisture has brought serious challenges for commercial roofs.
At Weathercraft Co., we’ve seen a surge in leak calls from property owners and managers caught off guard by the wettest season in recent memory. It’s a reminder that Colorado’s unpredictable climate demands a proactive approach to roof care.
Why More Rain Means More Roof Problems
Unlike Seattle’s steady drizzle, Colorado’s storms are often intense and fast-moving. That means large volumes of water hit your roof at once. Here’s how that affects commercial systems:
-
Drainage systems get overwhelmed: Scuppers, gutters, and internal drains can quickly clog with leaves, pine needles, and debris. Pooling water puts extra stress on seams and membranes.
-
Freeze-thaw cycles accelerate damage: Rain followed by chilly nights can cause trapped water to expand and contract, splitting seams and flashing.
-
Small vulnerabilities become big leaks: A pinhole puncture or loose flashing might survive a dry year—but not when rain is pouring down week after week.
Why Colorado Roofs Require Extra Vigilance
Our state’s semi-arid climate often gives building owners a false sense of security. With fewer rainy days compared to coastal regions, leaks can go undetected until damage is severe. That’s why, even in normal years, proactive inspections are essential. But after a season like this, they’re non-negotiable.
The Right Inspection Routine
To stay ahead of water damage, Weathercraft recommends two inspections every year:
-
One professional inspection by an experienced commercial roofing contractor. We’ll identify structural or material issues, check seams, evaluate drainage, and provide recommendations before problems spread.
-
One in-house inspection by your facilities team. Walk the roof, check drains, look for ponding water, and note any visible changes.
The best times? Fall and early winter. These inspections help you catch water-related damage before freezing temperatures arrive and ensure your roof is ready for snow and ice.
Preventative Maintenance Pays Off
Investing in small, preventative steps now can save thousands later. Some of the most effective measures include:
-
Clearing drains and gutters regularly.
-
Reinforcing flashing and sealing seams.
-
Addressing ponding areas with tapered insulation or repairs.
-
Scheduling minor repairs before winter weather hits.
Don’t Let Colorado’s Rain Catch You Off Guard
This year’s record-setting rain is more than an inconvenience—it’s a reminder that Colorado roofs are being tested like never before. Whether you manage an office complex, retail center, or industrial facility, now is the time to schedule inspections and take preventative action.
