When it comes to roofing materials, there are various options available in the market. One such popular choice is a torch down roof, which is known for its durability and effectiveness in protecting structures from harsh weather conditions. However, if you have a fibreboard roof already installed, you may wonder if it is possible to install a torch down roof over it. In this article, we will explore this question in detail and provide you with the necessary information to make an informed decision.
Understanding Torch Down Roofing
Before diving into whether torch down roofing can be installed over fibreboard, it is essential to understand what exactly torch down roofing is. Torch down roofing is a type of modified bitumen roofing system that consists of asphalt and rubber additives. It typically comes in rolls, which are then adhered to the roof deck using a torch and heat. This process ensures a secure and long-lasting bond between the roof surface and the material.
Advantages of Torch Down Roofing
Torch down roofing offers several advantages that make it a popular choice among homeowners and professionals. Some of the key benefits include:
- Durability: Torch down roofs are highly durable and can withstand extreme weather conditions, including heavy rain, strong winds, and even hail.
- Waterproofing: The application process of torch down roofing involves melting the material with a torch, creating a watertight seal that prevents leaks.
- Low Maintenance: Torch down roofs are relatively low maintenance, providing long-term protection and reducing the need for frequent repairs.
- Flexibility: Torch down roofing is flexible, adapting to the movements and settling of the building over time without damaging the roof.
Installing Torch Down Roof Over Fibreboard
When it comes to installing a torch down roof, it is generally recommended to have a smooth and stable surface to ensure proper adhesion and prevent future issues. Fibreboard, on the other hand, is a type of roof decking material commonly used in older roofs and is composed of compressed wood fibers bonded together.
While torch down roofing can be installed over various types of roof decking materials, such as plywood or concrete, fibreboard poses unique challenges. The main concern is the potential for heat damage to the fibreboard during the torching process. The excessive heat used to attach the torch down materials may cause the fibreboard to delaminate, warp, or even catch fire.
Considering Safety and Regulations
The installation of torch down roofing requires careful consideration of safety and adherence to local building codes and regulations. In some areas, installing torch down roofing over fibreboard may be strictly prohibited due to safety concerns. Therefore, it is vital to consult with a professional roofing contractor or local authorities before proceeding with the installation.
Alternative Solutions
If it is determined that installing torch down roofing directly over fibreboard is not feasible or allowed, there are alternative solutions available. One option is to remove the fibreboard and replace it with a suitable roof decking material, preferably one that is compatible with torch down roofing, such as plywood. This approach ensures a secure and long-lasting installation.
Another alternative is to consider a different roofing system altogether. Roofing options like a single-ply membrane or a metal roofing system can offer similar benefits to torch down roofing while being compatible with fibreboard roofing materials.
While torch down roofing is a popular and effective choice for many homeowners, installing it directly over fibreboard can present challenges and safety concerns. It is crucial to consult with professionals and local authorities to determine the best course of action and ensure compliance with building codes and regulations. Exploring alternative roofing systems may also be a viable option to consider in order to achieve the longevity and protection your structure needs.
