What Should Northwest Arkansas Property Managers Check on Commercial Roofs in Winter?
Northwest Arkansas (NWA) winters are notoriously unpredictable. From the ice storms in Bentonville and Bella Vista to the fluctuating freeze-thaw cycles in Fayetteville, Springdale and Rogers, commercial roofs in our region take a beating. For property managers, a proactive winter maintenance strategy isn't just about preventing leaks, it’s about protecting the building's structural integrity and your bottom line.
Here is the essential winter roof checklist for Northwest Arkansas property managers, optimized to help you stay ahead of the "Big Freeze."
1. Clear and Inspect Drainage Systems
In NWA, we often see "rain-to-ice" events. If your drainage is blocked, that standing water becomes a heavy ice block that can warp your roof deck or tear the membrane.
Drains and Scuppers: Ensure they are free of late-autumn leaves and debris. On flat commercial roofs, even a small blockage can cause significant ponding.
Gutter Integrity: Check for sagging or loose brackets. The weight of Arkansas sleet and ice can pull gutters away from the building if they aren't securely fastened.
Downspouts: Verify that water is discharging away from the foundation to prevent "ice-jacking" near the building base.
2. Evaluate Membrane Seams and Flashings
Cold temperatures cause roofing materials to contract. This "thermal shock" is a leading cause of seam failure in TPO, EPDM, and PVC systems.
Seam Stress: Look for areas where the membrane appears to be pulling or "tenting."
Flashings and Penetrations: Check the seals around HVAC units, vents, and skylights. These are the most common leak points during the winter as sealants can become brittle and crack in sub-freezing temperatures.
Parapet Walls: Inspect the coping caps and joints. If moisture gets behind the parapet during a thaw and then refreezes, it can cause masonry or metal damage.
3. Monitor for "Ice Damming" on Sloped Sections
While more common on residential roofs, many NWA commercial complexes have sloped sections or metal accents.
The Freeze-Thaw Cycle: When heat escapes through the roof, it melts snow, which then refreezes at the cold eaves. This creates an ice dam that forces water up under the roofing material.
What to Check: Look for large icicles or "ice ridges" along the edges. This often indicates a need for better insulation or attic ventilation.
4. Perform an Interior "Deep Dive"
Sometimes the best way to inspect a roof in winter is from the inside, especially if the roof surface is too slick for a safe walk-through.
Ceiling Stains: Look for yellow or brown water rings, particularly around support columns and external walls.
Musty Odors: A persistent "damp" smell in the warehouse or office often signals trapped moisture in the insulation.
Utility Bill Spikes: If your heating costs are skyrocketing, it may be due to "wet insulation." Once roof insulation gets wet, it loses its R-value, forcing your HVAC to work double-time.

Frequently Asked Questions (FAQ)
Q: How often should I check my commercial roof in the winter? A: We recommend a thorough inspection after every major "ice event" or heavy snowfall, and at least one professional check-up mid-season.
Q: Can commercial roofs be repaired in freezing temperatures? A: Yes, but it requires specialized materials. Standard adhesives won't bond below 40°F, so we use mechanical fasteners or cold-weather-specific sealants.
Q: What is the biggest roof threat in Northwest Arkansas? A: The "Freeze-Thaw-Freeze" cycle. When water gets into a crack, freezes (expands), melts, and then freezes again, it acts like a slow-motion sledgehammer on your roof.
