3 Winter Weather Roof Hazards

Chattanooga commercial roof Winter Weather Roof HazardsWinter takes a toll on the roof, especially in harsh climates. Extreme temperatures and weather conditions can create problems that may lead to costly commercial roofing repairs, if not properly maintained. Here are 3 winter weather roof hazards to avoid:

Ice & Snow Buildup

While we may not get much snow down in the south, it has happened. Because most commercial roofing is not pitched, it can allow for the accumulation of rainwater, snow or snowmelt. The winter weather hazard for your commercial roof occurs in climates with below freezing temperatures. When temperatures drop, rainwater or snowmelt freezes and/or refreezes in a freeze thaw cycle, creating an ice dam. The result? The roof may hold a significant amount of weight from water ponding, if not properly drained. Ponding water can severely shorten the longevity of your commercial roof, as it can cause leaks and long-term structural damage.

Wind Damage

Because flat roofs aren’t completely flat (allowing for water run off), there is still a chance for wind damage, just as with any pitched roof. While commercial roofs are tolerable to windy conditions, excess winds can damage the roof, allowing moisture to get underneath roofing materials.

Is your Chattanooga commercial roof ready for winter? Here are three tips to get ready!

  • Identify leaks sooner than later – Snow and ice buildup can make finding and repairing leaks harder.
  • Schedule a roof inspection in Chattanooga – Following your detailed roof inspection, we will report any issues for repair.
  • Repair and prepare – Tennessee Roofing will repair penetrations, curbs, skylights, ducts, and flashings, as needed.

Our Tennessee Roofing professional will check for areas for loose seals, signs of standing water, water damage, or things like rusted flashing and metal fasteners. While defects in flashing and sealant failure at penetrations are the leading causes of leaks, splits in the membrane, separations at seams, ridges, blisters and deterioration are also red flags that must be addressed before it’s too late. Neglecting to repair a damaged commercial roof this winter may lead to building damage, which can be dangerous and costly.

Protect Your Commercial Roof From Season Hazards

At Tennessee Roofing and Construction, we always recommend customers call us for routine inspections of your facility roof as well as periodic maintenance to make any necessary repairs before old man winter hits. Several factors can cause roof damage, but one major concern during this time of year are falling leaves. While colorful, autumn leaves are beautiful, they can wreak havoc on commercial roofing structures.

Commercial Roof Drain Buildup

How could leaves as light as a feather cause so much roof damage? Moisture. From rain and water drainage, wet leaves become a heavy mass that often clogs drains, blocks scuppers and invites mold, fungi and mildew to grow. If not properly removed, leaves can lead to back up, which increases the weight on the roof deck. Did you know that 1 inch of standing water weighs approximately 5 lbs. per inch, per square foot of roof surface assembly? Over time, even a small amount of standing water may damage the roofing membranes, reducing the life expectancy of your roof.

As cold weather approaches, areas of ponding may be at risk of leaks, as water freezes and expands. The additional weight of ice or snow can cause structural damage and expensive repairs, or even roof collapse in areas of poor drainage due to debris.

We recommend frequent checks and prompt debris-removal, necessary to prevent buildup or blockage. Drains and gutters should be cleared in the fall before below-freezing temperatures create frozen blockages from leaf debris.
