A Metal vs. Composite Breakdown
Winter roofing projects used to be something contractors avoided. Cold temperatures, moisture, and short daylight hours can complicate installation, especially for materials that rely on adhesives or precise weather conditions to perform correctly. So, can you install a new roof in the Winter?
Today’s roofing systems and installation practices have evolved, making winter roof installations not only possible but sometimes preferable. If you’re wondering whether you can replace your roof during the colder months, and whether metal or composite shingles handle winter better, this guide walks you through everything you need to know.
Is It Possible to Install a New Roof During Winter?
In most cases, yes, you can absolutely replace a roof during winter, as long as the temperature and weather conditions are safe for installers and suitable for the roofing material.
The key variables are:
- Temperature (typically affecting adhesives and sealants)
- Ice, snow, or wet surfaces
- Wind conditions
- Material flexibility
- Crew experience with cold-weather installations
Professional roofing companies like Mountaintop Metal Roofing follow strict safety and performance guidelines, ensuring each roof is installed to last no matter the season.
Why Do Some Roofers Avoid Winter Roof Replacements?
Some roofing crews limit winter installations because the materials they use (primarily asphalt/composite shingles) don’t perform well in the cold. Cold weather makes shingles brittle and difficult to handle, and the seal-down strips that help create a watertight bond often don’t activate unless temperatures are warm enough.
Winter doesn’t necessarily mean “no installations.” It simply means not all materials respond the same way.
How Does Cold Weather Affect Composite Shingle Installation?
Composite shingles are the most sensitive roofing material when it comes to winter installation. Contractors must take extra care, and sometimes delay projects, because:
1. Shingles Become Brittle
Below about 40°F, asphalt and composite shingles stiffen. This makes them more prone to cracking when nailed or bent.
2. Sealant Strips Don’t Bond Properly
Shingles rely on sun-activated adhesive strips to create an airtight seal. In winter, these strips may not bond without artificial heat or additional manual sealing.
3. Risk of Improper Nailing
Cold shingles don’t lie flat as easily, and hand-nailing becomes more difficult.
4. Increased Chance of Future Blow-Offs
If shingles never fully seal, even after installation, wind can lift them over time.
Result: Composite shingles can be installed in winter, but only with additional steps, more labor, and a higher risk of performance issues.
How Does Cold Weather Affect Metal Roof Installation?
Metal roofing is significantly more winter-friendly. Aluminum and copper panels respond far better to cold temperatures than asphalt-based products.
1. No Adhesives Required
Metal roofing systems lock together using fasteners and interlocking seams, not heat-activated seal strips, so they perform consistently in any season.
2. Panels Stay Flexible
Unlike brittle shingles, metal panels don’t crack or split in cold weather.
3. Faster Installation
Metal roofing installs in large sections, which is ideal during shorter winter days.
4. Superior Winter Performance
Metal roofs excel in winter long after installation:
- Snow slides off instead of piling
- Ice dams are less common
- Panels resist temperature fluctuations exceptionally well
Result: Metal roofing is one of the best materials for winter roof replacements, provided the roof surface is safe for crews to access.
Are Winter Roof Installations More Affordable?
They can be, but not always. Here’s why:
- Some contractors offer winter discounts to keep crews working.
- Composite roofs may cost more due to added labor to compensate for cold material handling.
- Metal roofing costs typically stay consistent because the installation process doesn’t change drastically in colder weather.
If you’re already experiencing leaks or aging shingles, waiting until spring can cause more damage than acting now, especially for composite roofs that deteriorate faster.
Is Winter a Good Time to Switch From Composite to Metal Roofing?
For many homeowners, winter is the perfect time to switch, especially if the roof is leaking or approaching the end of its lifespan.
Metal roofing has several advantages in cold climates:
- Handles cold installation well
- Provides superior winter insulation and efficiency
- Eliminates ice-dam-causing valleys and weak points
- Lasts a lifetime with minimal maintenance
- Offers fire resistance and durability
If a storm or heavy freeze damaged your roof, metal roofing provides long-term protection rather than a temporary fix.
What Should You Expect From a Professional Winter Installation?
Whether installing composite or metal, a reputable roofing company will:
- Use safe-access protocols for snow or ice
- Monitor temperatures for material best-practice requirements
- Protect exposed decking from moisture
- Prevent slipping hazards with safety harnesses and walkway systems
- Plan installation windows based on weather forecasts
- Maintain clear communication about scheduling adjustments
Mountaintop Metal Roofing follows a safety-first approach and only installs when conditions allow us to deliver a lifetime-quality roof.
Do Winter Roof Installs Take Longer?
Winter installations can take longer because:
- Days are shorter
- Weather windows are narrower
- Composite shingles require slower handling
However, metal roof installations often remain efficient because:
- Large panels cover more surface area
- Metal systems require fewer temperature-dependent steps
- Crews can complete more work during each installation window
Most Mountaintop metal roofs are completed within the same timeframe as a summer project.
Does Installing in Winter Affect Warranty Coverage?
With a reputable contractor, winter does not impact your warranty as long as proper installation guidelines are followed.
Mountaintop’s metal roofing systems come with a lifetime, non-prorated, fully transferable warranty, regardless of season.
Composite roofing warranties may vary depending on the manufacturer. Some require temperatures above certain thresholds for adhesion-based components.
This is another reason many homeowners choose metal when timing is tight.
FAQs About Winter Roof Installation
1. Will a winter installation increase the risk of leaks?
Not when performed correctly. Metal roofing installs safely in winter because it doesn’t rely on adhesives. Composite shingles are more sensitive but still safe with proper technique.
2. Can snow interfere with the installation process?
Snow may delay work temporarily, but crews can clear safe sections and work in windows of good weather. Metal roofing makes clearing easier due to its smooth surface.
3. Is winter installation more expensive?
Metal roofing prices typically stay consistent. Composite roofing may cost more due to extra labor or sealing methods.
4. Will my roof seal properly in cold weather?
Metal roofs don’t require heat-activated seals, so they perform beautifully in cold climates. Composite roofs may need warmer days or extra manual sealing.
5. How do I know if winter is the right time to replace my roof?
If your roof is leaking, shedding granules, curling, or visibly failing, waiting until spring can lead to further damage. A professional inspection can help you decide.
