What is modified bitumen roofing?

Modified bitumen roofing is a type of asphalt-based roofing material that is commonly used for flat or low-slope roofs. It is made by adding modifiers such as plastic or rubber to the asphalt to improve its durability, flexibility, and weather resistance.

Modified bitumen roofing can come in either rolls or individual shingles. The rolls are typically installed by heating the material with a torch or hot asphalt, while the shingles can be self-adhered or nailed down.

Some of the benefits of modified bitumen roofing include:

1. Durability: Modified bitumen roofing is known for its strength and ability to withstand harsh weather conditions, such as high winds and heavy rainfall.

2. Flexibility: The added modifiers in the asphalt make the roofing material more flexible, allowing it to expand and contract with changing temperatures without cracking.

3. Energy efficiency: Some modified bitumen roofing systems are available with reflective coatings that can help reduce energy costs by reflecting sunlight and heat away from the building.

4. Easy maintenance: Modified bitumen roofing is relatively easy to maintain and repair, making it a cost-effective option for commercial and residential buildings.

Overall, modified bitumen roofing is a popular choice for flat or low-slope roofs due to its durability, flexibility, and easy maintenance. It is important to hire a professional roofing contractor for installation to ensure proper application and longevity of the roofing system.
