Preparing Your Commercial Roof for Winter: 6 Essential Tips

Preparing Your Commercial Roof for Winter

How do I prepare my commercial roof for winter?

To prepare your commercial roof for winter, you need to inspect it, make any necessary repairs, clean out gutters and drains, and deal with nearby trees and HVAC units. It’s about catching small issues before they become big, expensive problems when the weather gets bad.

What You See (The Symptom)

Before winter hits, you might not see obvious problems, but you might notice things like standing water after a rain, leaves clogging gutters, or small cracks on your roof’s surface. Sometimes, you just know your roof hasn't been looked at in a while, and you don't want to find out it has issues when snow and ice are covering everything.

The Problem (and what it costs if ignored)

Ignoring your roof before winter can lead to serious headaches. Small cracks can turn into big leaks when water freezes, expands, and thaws repeatedly. Clogged drains mean water has nowhere to go, leading to ponding and extra weight on your roof, which is bad enough before you add heavy snow and ice. If water gets under your roof membrane and the insulation gets wet, that insulation loses its R-value, meaning your building loses more heat. This jacks up your energy bills and can lead to mold inside. Worse, saturated insulation and a failing roof deck might mean you can’t restore your roof with a coating system; you might need a full tear-off and replacement, which costs a lot more time and money. When winter hits, repairs are harder, more expensive, and sometimes impossible until spring, leaving your building exposed.

The Solution (How the work is done)

Getting your commercial roof ready for winter is mostly about being proactive. Here’s how we tackle it:

1. Roof Inspection: The first step is a thorough look at your roof. A Conklin-trained contractor will get on the roof and check every part of it. We look for cracks, punctures, open seams, loose flashing around edges and penetrations (like vents and pipes), and any signs of water damage. We check the condition of the existing membrane and look for areas where water might be pooling. We also assess the deck and look for signs of wet insulation. If the insulation is wet or the deck is failing, a coating system might not be the right fit, and we’ll tell you that upfront.
2. Make Repairs: If the inspection finds any issues, we fix them before winter. This means sealing cracks, repairing punctures, tightening up loose flashing, and making sure all seams are properly adhered. For a coating system to work, the existing roof has to be sound. We want to stop any leaks or potential leaks right away so water doesn't get a chance to cause more damage during the freeze-thaw cycles of winter.
3. Clean Gutters and Drains: This might seem simple, but it's crucial. We make sure all gutters and downspouts are clear of leaves, debris, and anything else that could block water flow. We also check the roof drains to ensure they're open and working. Proper drainage prevents water from sitting on your roof, which is especially important when temperatures drop and that standing water turns to ice.
4. Trim Trees: If you have trees overhanging your building, we recommend having them trimmed. Heavy snow and ice can weigh down branches, causing them to break and fall onto your roof, leading to punctures and serious damage. This is often a job for a separate tree service professional.
5. Check HVAC Units: While we don’t work on HVAC, we often see issues around these units. It's a good idea to have your HVAC contractor inspect their units and the surrounding flashing before winter. Make sure they are in good working order and that their connections to the roof are sealed tight.

Our goal is to make sure your roof is watertight and ready to handle whatever winter throws at it. If your roof is too far gone with widespread wet insulation or a failed deck, we’ll let you know that a restoration isn't possible and explain why. Our Conklin roof coating systems are designed to protect and extend the life of your roof, but they need a solid foundation to start with.

Frequently Asked Questions

When is the best time to prepare my commercial roof for winter?

The best time is in the fall, before the first frost or heavy snowfall. This allows time for inspections and any necessary repairs to be completed in good weather. However, it's never too late to take a look if winter hasn't fully set in.

Can a commercial roof coating help my roof in winter?

Yes, absolutely. A commercial roof restoration with a Conklin acrylic coating creates a seamless, watertight barrier that protects your roof from ice, snow, and freezing temperatures. It also reflects sunlight, which can help keep the roof surface cooler in summer, but its primary benefit in winter is sealing the roof against water intrusion.

What if I find a leak during winter?

Finding a leak in winter is tough. While temporary fixes might be possible, comprehensive repairs are much harder and less effective in freezing temperatures. That's why pre-winter preparation is so important. If you have a leak, call us, and we'll assess the situation and advise on the best course of action, even if it means waiting for better weather for a full repair.
