When it comes to roofing materials, there are various options available to suit different climates and conditions. One popular choice is torch down roofing, also known as modified bitumen roofing. This type of roofing system is often preferred for its durability, flexibility, and ease of installation. However, a common question that arises is whether torch down roofs can be installed in cold climates. In this article, we will explore the suitability of torch down roofing in colder regions and provide insights into its installation process.
Understanding Torch Down Roofing
Before delving into the compatibility of torch down roofing in cold climates, it is essential to understand what it entails. Torch down roofing is a type of membrane roofing that is commonly used on flat or low-sloping roofs. It consists of multiple layers of asphalt membranes, reinforced with polyester or fiberglass for added strength and stability. To adhere the membranes to the roof, a propane torch is used to melt the asphalt backside, effectively “torching it down” onto the substrate.
Benefits of Torch Down Roofing in Cold Climates
Although torch down roofing is typically associated with warmer climates, it can be a suitable option for cold regions as well. This is due to several advantages that torch down roofing offers in colder climates.
- Flexibility: Torch down roofing membranes are designed to have a high level of flexibility, even in low temperatures. This flexibility allows the material to expand and contract without causing damage, which is crucial in cold climates where temperature fluctuations are common.
- Superior Waterproofing: Torch down roofing provides exceptional waterproofing capabilities. The multiple layers of asphalt membranes create a strong and watertight barrier, preventing water from infiltrating the roof. This is particularly important in cold climates where rain, snow, and ice are prevalent.
- Durability: Torch down roofing is known for its durability and resistance to extreme weather conditions. It can withstand heavy snow loads, ice buildup, and even hail. This resilience makes it a suitable choice for colder regions where weather-related challenges are more pronounced.
Installation Process in Cold Climates
While torch down roofing can be installed in cold climates, certain precautions should be taken during the installation process to ensure its effectiveness and longevity.
- Warm Ambient Temperature: Before installing a torch down roof in cold weather, it is crucial to ensure that the ambient temperature is warm enough. Cold temperatures can affect the bonding process, making it essential to choose a day with mild weather conditions for installation. If the temperature is too cold, the torch may struggle to melt the asphalt sufficiently, leading to insufficient adhesion.
- Proper Heating: To counteract the cold weather, heating the substrate before installation can help to create a suitable surface for adhesion. Using a propane-fueled heater or a hot air blower can warm the surface, ensuring proper melting of the asphalt and promoting strong adhesion.
- Adhesive Primers: Applying an adhesive primer to the roofing substrate can enhance the bonding process in cold temperatures. The primer helps to improve the contact between the roofing material and the substrate, ensuring a secure and long-lasting installation.
Torch down roofing can indeed be installed in cold climates with proper planning and execution. The flexibility, superior waterproofing capabilities, and durability of torch down roofs make them a suitable option for regions prone to harsh weather conditions. However, it is important to consider the ambient temperature during installation, provide proper heating, and use adhesive primers to ensure a successful and long-lasting application. By following these guidelines, homeowners and contractors can confidently choose torch down roofing for their cold climate roofing needs.
