How to Protect Your Commercial Roof Through Winter
For most facility managers and business owners, the end of the year is a busy time - budgets are closing, maintenance is wrapping up, and everyone’s preparing for the new year. But before you check “roof” off your to-do list for the winter, it’s worth making sure your building’s first line of defense is actually ready for the cold, wet months ahead.
Even though winters in the Upstate are mild, the combination of moisture, cold air, and temperature swings can quietly create costly problems on commercial roofs - especially flat or low-slope systems.
Here’s what every business should know about protecting their roof through the winter.
1. Standing Water and Debris Are Your Roof’s Worst Enemies
Flat and low-slope commercial roofs are designed to shed water - but not if the drains are clogged. When leaves, dirt, or debris block your drains, that standing water adds hundreds of pounds of extra weight to your roof and accelerates membrane deterioration.
If water sits for more than 48 hours, it’s already damaging insulation, seams, and decking. That’s why we recommend cleaning drains and gutters before winter and following a preventive maintenance schedule year-round.
2. Temperature Swings Can Stress Roof Materials
Even without snow, Upstate South Carolina sees major day-to-night temperature shifts in the winter months. That expansion and contraction can cause seams to separate, flashing to loosen, and sealants to crack.
A simple inspection can identify these stress points before they become leaks - which often appear inside the building long after the damage begins.
3. Hidden Leaks Can Interrupt Operations
A small leak in a flat roof doesn’t always drip straight down. Water can travel horizontally under the membrane for several feet before it shows up inside. By the time you see a stain on a ceiling tile, that leak may have already damaged insulation or electrical components.
Our Preventive Roof Maintenance Program includes thermal scans to detect hidden moisture - giving you data before you ever see the problem.
4. Plan Repairs Before the Busy Season
If you wait until spring to schedule roofing work, you’re competing with every other business doing the same thing. Winter is actually an ideal time to perform minor repairs, touch-ups, and inspections - with less disruption to your operations.
Our team at Beemer KangaRoof works year-round, so your facility stays protected even during the off-season.
