When winter weather hits the Midwest, your commercial roof becomes the first line of defense against snow, ice, and freezing temperatures. The best way to avoid costly surprises? Make sure your roof is ready before the first hard freeze.
At Jewett Roofing, we’ve seen firsthand how a few preventive steps in late fall can save building owners thousands of dollars in emergency repairs later. Here’s what to focus on when preparing your roof for winter.
1. Schedule a Professional Roof Inspection
A thorough inspection is the foundation of any winter prep plan. Trained roofing professionals can spot issues that often go unnoticed—like small punctures, seam separations, or deteriorated flashing—that become major leaks once the freeze–thaw cycle begins.
During an inspection, your contractor should also check:
The overall condition of the membrane
Roof edges, joints, and terminations
Penetrations around HVAC units and vents
Areas prone to ponding water
Catching these early gives you time to make repairs while conditions are still favorable.
2. Clear Drains and Gutters
Flat and low-slope roofs depend on clear drainage systems to shed melting snow and rain. Even minor clogs can cause ponding water, which later freezes, adds weight, and stresses the roofing membrane.
Before winter sets in, make sure all drains, scuppers, and downspouts are clear of leaves, debris, and sediment. This step alone can prevent major problems once temperatures drop.
3. Check for Loose Flashing and Edge Metal
Winter winds and fluctuating temperatures can quickly turn loose flashing into a leak. Inspect all metal edges, terminations, and curbs for movement or gaps. Tighten fasteners and reseal areas where adhesive or caulking has failed.
Taking care of these small details before winter can prevent water from infiltrating and refreezing beneath the membrane—one of the leading causes of roof blisters and cracks.
4. Inspect the Roof After the First Snowfall
Your first snow event of the season is a valuable test. Once it’s safe to access the roof, check how snow and meltwater are moving (or not moving) off the surface. Areas of uneven melting or pooling can signal insulation or drainage issues that should be addressed before more storms arrive.
5. Maintain an Emergency Action Plan
Even with strong preventive care, unexpected events happen—especially during Midwest winters. Make sure you have a plan in place that includes:
Your roofing contractor’s emergency contact information
Clear access to roof hatches or ladders
Guidelines for when and how to safely remove snow buildup
Partnering with a trusted roofing team before you need them ensures help is just a phone call away when conditions worsen.
