When snow blankets Houston’s skyline, it creates more than just a picturesque scene – it presents unique challenges for commercial property owners. With buildings designed primarily for heat and hurricanes, these rare winter events demand special attention and understanding.
Understanding the Unusual: Houston’s Winter Building Challenges
Houston’s commercial architecture tells a story of adaptation to heat, humidity, and tropical storms. However, when winter arrives unexpectedly, our buildings face circumstances they weren’t primarily designed to handle. This reality makes understanding winter weather impacts crucial for property owners and managers.
Why Snow Loads Are a Concern
Did you know that the average commercial roof in Houston is designed to handle about 20 pounds per square foot (psf) of weight?
While this seems sufficient, snow and ice can quickly tip the scales. Here’s why:
- Snow weight: Fresh snow can weigh around 5.2 pounds per square foot.
- Freeze-thaw cycles: Snow that melts and refreezes becomes significantly heavier.
- Roof damage: Freeze-thaw cycles are responsible for 85% of winter-related roofing issues.
- Uneven weight distribution: Uneven snow piles can create pressure points, adding extra stress to your roof.
Warning Signs of Roof Trouble: What to Look For
The first step to protecting your commercial roof during rare snow events is vigilance. Pay close attention to your building for any of the following warning signs:
- Dripping Water or Ceiling Stains: New water stains on ceilings or walls are often the first signs of trouble. These may indicate leaks caused by ice dams or melting snow.
- Unusual Creaking or Popping Sounds: If you hear noises you don’t normally notice, it could mean your roof structure is under stress from snow weight or freeze-thaw cycles.
- Sagging Ceiling Tiles or Beams: This is a serious red flag and may indicate excessive weight on your roof.
- Ice Along Roof Edges: Ice dams can prevent proper drainage, forcing water back up under your roof covering.
- Doors Suddenly Misaligned: A surprising but common issue, doors that won’t close properly could indicate shifting due to structural strain.
If you notice any of these signs, act quickly. Minor issues can escalate into major problems if left unaddressed.
Exterior Indicators: The roof’s exterior can tell its own story through the following
- Ice formation along edges (ice damming)
- Visible drainage blockages
- Changes in roof membrane appearance
- Snow accumulation patterns
Things to Avoid
Sometimes, the best course of action is knowing what to avoid. Here’s a list of critical “don’ts” to help you steer clear of costly mistakes:
- Don’t Walk on a Snow-Covered Roof: Walking on a slippery roof is incredibly dangerous and can also cause additional damage. Always leave roof inspections to the professionals.
- Don’t Use Chemical De-Icers: While it might seem like a quick fix, de-icers can corrode your roofing materials, causing long-term damage.
- Don’t Ignore Small Leaks: Even a minor drip can signal a larger issue. Address leaks immediately to prevent structural or interior damage.
- Don’t Delay a Professional Inspection: Time is of the essence when dealing with snow-related roof issues. Waiting too long can turn a simple repair into a costly replacement.
Immediate Actions to Take:
Drainage Management
Proper drainage remains crucial during winter weather:
- Monitor drain functionality regularly
- Ensure clear paths for water flow
- Verify downspout and gutter effectiveness
- Watch for signs of ice damming
Documentation Protocol
Maintain detailed records of your roof’s condition:
- Take dated photographs from safe vantage points
- Document any existing or new leaks
- Keep a detailed log of observations and changes
- Record when issues first appear
