Winter 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.
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.
