Are you looking for a reliable and durable roofing solution for your roof installation? If yes, you might be confused about the choice between modified bitumen and built-up roofs. While both are popular options for flat roof installations, they have distinct differences that make them suitable for different applications.
What Is Modified Bitumen Roofing?
Modified bitumen roofing is a type of asphalt roofing modified with polymer additives, increasing its durability, flexibility, and resistance to extreme weather conditions. It is commonly used for low-sloped roofs and has a lifespan of about 20 to 30 years with proper maintenance. Bitumen roofing is also relatively easy to install, making it a cost-effective option for flat roof installations.
What Is Built-up Roofing?
Built-up roofs, also known as BUR, refer to a traditional roofing option that consists of multiple layers of felt or fiberglass material, tar, and gravel. It has been in use for over a century and is known for its durability and long lifespan. Built-up roofs are also good insulators for homes with extreme temperature changes.
Key Differences Between Modified Bitumen and Built-Up Roofs
While modified bitumen and built-up roofs are suitable for roof installations, their differences make them better suited for different applications. Here are some of the key differences.
Material Composition
Bitumen roofing is made of asphalt and polymer modifiers while built-up roofs contain multiple layers of felt or fiberglass material, tar, and gravel.
Installation
Bitumen roofing is relatively easy to install, and the process involves rolling out the modified bitumen sheets onto the roof and heating them to create a tight seal. In contrast, built-up roofs require more labor-intensive installation, involving multiple layers of felt or fiberglass material and hot tar.
Maintenance
Bitumen roofing requires regular maintenance to ensure longevity while built-up roofs are relatively low-maintenance and require occasional inspection and repair.
Lifespan
Bitumen roofing has a lifespan of about 20 to 30 years while built-up roofs can last up to 50 years with proper maintenance.
Which One Is Best for Your Home?
The choice between modified bitumen and built-up roofs largely depends on your needs and preferences. If you are looking for a cost-effective and easy-to-install roofing option, modified bitumen roofing is an excellent choice.
