When a roof is leaking, the last thing a homeowner wants to do is wait for spring. The good news is that, yes, it is possible to replace a roof in the winter. While it presents unique challenges, professional roofing contractors are equipped to handle cold-weather installations safely and effectively.
Challenges of Winter Roof Work
Winter conditions can make a roofing job more difficult and potentially more dangerous. Understanding these challenges is key to a successful project.
Temperature and Material Issues
Standard asphalt shingles require warm temperatures to seal properly. The sun’s heat melts the sealant strip on the underside of each shingle, bonding it to the shingle below and creating a watertight seal. In cold weather, this process is delayed. Without a proper seal, shingles are more susceptible to being lifted or torn off by high winds, leaving your roof vulnerable.
Safety Risks from Ice and Snow
Ice, frost, and snow on a roof create a hazardous work environment. A contractor’s primary concern is the safety of their crew. Slippery surfaces significantly increase the risk of falls and other injuries. A professional roofing company will have a strict safety protocol, including the use of safety harnesses, ropes, and other fall protection equipment.
Why It Can Still Be Done
Despite the challenges, winter roofing is a viable option and can even come with some benefits.
Flexible Scheduling
The spring and summer seasons are the busiest for roofing companies. In winter, many contractors have more flexible schedules. This can mean a quicker start time for your project and more focused attention from your roofing crew.
Emergency Repairs and Leaks
If you have a serious leak or significant storm damage, waiting until spring is not an option. A professional contractor can provide an immediate solution, even in cold weather. They can make temporary repairs to stop the leak and then return for a full replacement when the weather allows for proper shingle sealing.
Best Practices for Cold-Weather Roofing
For a successful winter roofing project, contractors use specialized techniques and materials to combat the cold.
Proper Shingle Storage and Handling
Manufacturers have specific guidelines for installing shingles in cold weather. Contractors will often store shingles in a heated warehouse or a truck until they are ready to be installed, ensuring they are pliable and easier to handle. Once on the roof, they are installed as quickly as possible.
Specialized Adhesives and Tools
To ensure the shingles seal properly, contractors often use specialized cold-weather adhesives or manual sealing with dabs of roof cement. While this adds a step to the process, it ensures that the shingles are secured and won’t be dislodged by the wind. The final, permanent seal will then occur naturally when the warmer weather returns.
When to Wait Until Spring
While winter roofing is possible, it’s not always the best choice for every situation.
Severe Storms and Extreme Cold
If the weather is too cold (typically below 20°F) or if there is heavy snow or freezing rain, a contractor may recommend rescheduling the project. Working in these conditions is unsafe and can compromise the quality of the installation.
Non-Urgent Replacements
If your roof is old but not actively leaking, and the project is not an emergency, waiting until spring is often the most practical choice. Warmer temperatures allow for a faster and more efficient installation, and the shingles will seal on their own without the need for manual adhesive.
FAQs
Does cold weather affect warranties?
Most roofing manufacturers’ warranties include clauses for cold-weather installation, as long as the contractor follows the manufacturer’s specific guidelines and best practices. Always use a certified professional who knows these guidelines to ensure your warranty remains valid.
Is it more expensive in winter?
Typically, the cost of the materials and labor remains the same, though some contractors may charge a small premium for working in extreme cold. However, the potential for better scheduling and a more focused crew can offset any minor price differences.
