What happens if your commercial roof starts leaking in the middle of a Central PA winter? Do you really have to wait until spring—or can it be fixed or replaced safely in cold weather?
If you’re asking these questions, you’re not alone. Many building owners and property managers assume roofing work has to pause until the warmer months. But the truth is, commercial roof replacement can be done during winter—as long as it’s done the right way.
At Equity Commercial Roofing, we’ve helped dozens of commercial clients in Central Pennsylvania complete winter roofing projects safely, efficiently, and with long-term durability in mind. Whether we’re working on a retail plaza, office building, or industrial site, we follow the right process, use the correct materials, and adjust to weather conditions to ensure every roof performs as it should—regardless of the season.
In this article, you’ll learn:
Which commercial roof systems can be installed during cold weather (and which can’t)
How temperature, snow, and wind affect installation quality and timing
What to ask your contractor about adhesives, downtime, and safety
How to decide if replacing your roof now—or waiting until spring—is the better option for your building and budget
Many commercial roofs in Central PA can be replaced in winter with the right planning and materials. Experienced roofers will follow manufacturer specifications and work around the weather's limitations.
That said, not all roofing systems respond the same way to winter temperatures. Some are better suited for cold-weather installs than others.
| Roofing System | Can It Be Installed in Winter? | Notes |
| Mechanically Attached TPO | Yes | No adhesives required; flexible in cold temps |
| Mechanically Attached PVC | Yes | Cold-weather friendly; ideal for facilities with chemical or grease exposure |
| EPDM (Rubber Roofing) | Yes, with prep | Needs time to relax before fastening to prevent wrinkling or bubbling |
| Roof Coatings | No | Require dry, warm conditions to cure properly; not suitable for winter |
| Fully Adhered Systems | Depends | Require adhesives; only viable with cold-weather-rated products |
| Self-Adhered Membranes | Risky in cold temps | Often need 40°F and rising to bond properly |
The three most important environmental factors for a winter roofing job are temperature, moisture, and wind. These directly affect adhesive performance, surface preparation, and job-site safety.
Temperature: Adhesives typically require the roof deck to be at least 25°F and rising, depending on the product. Some materials need closer to 40°F.
Moisture: Snow, frost, or condensation on the deck must be removed completely before roofing begins. We never install over a wet surface.
Wind: Strong winds can lift materials during installation or even jeopardize worker safety. It’s important to monitor conditions daily and adjust accordingly.
Your roofer should track weather patterns closely and only move forward when conditions support a quality installation.
Winter roof installations require more cautious scheduling, temperature-sensitive handling, and daily sealing to prevent moisture intrusion.
Your Roofer Should:
Work in smaller, fully manageable sections each day
Start later in the morning and finish earlier to avoid the coldest/wettest hours
Keep adhesives warm (usually 70°F+) in heated boxes
Let EPDM membranes relax before fastening to avoid tension issues
Conduct test welds and probe seams to ensure strong bonding
These adjustments ensure safety, quality, and longevity, even in below-freezing temperatures.
Yes, but only after the roof deck is fully cleared and dry. Snow is a fact of life in Central PA, but it doesn’t stop a roof project.
If snow is present on the deck, we handle the removal ourselves. You won’t need to hire a third-party snow removal service. What we never do is install over wet or frozen surfaces. We’ll wait until the deck is clean, dry, and ready.
Winter roofing projects typically take slightly longer than summer ones due to shorter daylight hours and tighter working conditions. However, the difference is minimal when the project is well planned and properly staffed.
Here’s what changes:
Shorter daylight means shorter work windows
Crews may be on-site a few extra days, depending on conditions
Tear-offs happen in smaller sections to ensure a complete dry-in daily
Here’s what stays the same:
Your building stays watertight throughout the project
Our teams follow strict safety and quality protocols
We communicate clearly and build weather contingencies into the timeline
Yes, but only if the roofing system and adhesives are rated for cold-weather use, or if you're using mechanically attached systems that don't rely on bonding. That old “40°F and rising” rule is only partly true. Different adhesives and membranes have different requirements.
Fully Adhered Systems: Some require the deck to be at least 25°F and rising
Self-Adhered Membranes: Typically need warmer temps—closer to 40°F
Mechanically Attached Systems: Can often be installed regardless of temperature, making them ideal for winter
Winter installations can come with benefits like better scheduling availability, potential off-season pricing, and less disruption to business operations.
More scheduling flexibility (roofers are less booked in winter)
Potential off-season pricing if you’re flexible with timing
Less interference with business operations (fewer customers/foot traffic)
Before you approve a winter roofing job, ask about materials, adhesives, moisture handling, warranties, and daily sealing procedures. These questions help you avoid delays, warranty voids, and quality problems in cold conditions.
| Question to Ask Your Contractor | Why It Matters |
| What materials do you recommend for winter installs? | Some systems fail in the cold; others are built for it |
| Do you use cold-weather-rated adhesives? | Ensures proper bonding despite lower temperatures |
| How do you manage snow and ice on the roof deck? | Deck must be dry and safe before installation begins |
| How do you seal the roof at the end of each workday? | Prevents leaks or weather exposure overnight |
| Will the winter installation still be covered by warranty? | Confirms your investment is protected even in cold weather |
| Do you have experience with winter roofing in Central PA? | Local winter experience matters for timing and execution |
You came to this article wondering whether a commercial roof can actually be replaced during a Central PA winter. Now you know it can—when the right roofing system, installation process, and weather conditions all line up. Winter doesn’t automatically stop a roofing project. It simply changes how the work needs to be approached.
For many building owners, the real concern isn’t the cold. It’s the fear of leaks during construction, extended downtime, or a roof that won’t hold up because it was installed in freezing temperatures. Those are valid worries, and exactly why winter roofing requires planning, experience, and the right materials.
Before you decide whether to move forward this winter or wait until spring, the next logical question is: What is this going to cost me?
