Modified Bitumen roofing is one of the oldest roofing systems still in use for low-sloped roofs. Even with the availability of other single-ply roofing materials like TPO, PVC, or EPDM, to this day, it is still considered one of the more popular choices.
The biggest advantage of Modified Bitumen roofing is that it is highly tear-resistant when compared to other commercial roofing systems. If your roof is going to have foot traffic this may be the system for you!
The top layer can be treated to add “cool roof” features such as solar reflectance and thermal emission, or the ability to reflect sunlight, and release already-absorbed heat, respectively.
Bitumen is inherently waterproof, and several layers of it on a properly-installed roof makes modified bitumen roofs the most waterproof commercial roofing choice available.
Modified Bitumen can be applied in either hot or cold manners. When it is hot-applied torches are used in conjunction with a bonding adhesive to weld the material together creating a stronger than life bond.
Modified Bitumen can be applied in either hot or cold manners. When it is cold-applied, paint rollers or even mops can be used to spread a bonding agent across the spread of the roof. This is similar to how bonding adhesive is utilized on other types of low-sloped roofs.
