Great Choices for Low-Slope Commercial Roofs
Modified bitumen roofing (MBR) and built-up roofing (BUR) are both popular choices for low-slope or flat roofs, commonly used on commercial properties.
Modified Bitumen Roofing (MBR). This type of roofing comes in rolls. Install rolls directly onto the roof substrate. MBR is made with bitumen (a sticky, viscous substance) with reinforcement with modifiers like fiberglass or polyester fibers for added durability. MBR often uses multi-ply systems, offering extra protection against weather. There are two types: SBS, which enhances flexibility, and APP, which increases lifespan and flexibility.
Built-Up Roofing (BUR). BUR consists of multiple layers of ply sheets and asphalt, offering durability and redundancy. A final cap sheet or asphalt flood coat with granules provides added protection. BUR is highly resistant to harsh weather conditions like heavy rain, hail, snow, and high winds.
The Unique Benefits of Modified Bitumen RoofING (MBR)
Modified bitumen roofing systems offer several benefits, including tear-resistance, exceptional durability, and flexible strength that make them highly resistant to harsh weather conditions, falling debris, and typical signs of aging.
MBR is a flexible and versatile roofing material that can expand and contract with changes in weather without losing its structural integrity.
Finally, a modified bitumen roof is relatively simple to install, repair, and maintain. Patch tears or leaks easily.
This affordable, long-lasting roofing material is an ideal choice for commercial properties of all sizes.
Why Use Built-Up Roof Systems (BUR)?
Built-up roofing (BUR) has been a reliable choice for over a century, thanks to its time-tested technology. With multiple layers of protection, it provides redundancy that ensures underlying layers continue to offer protection against water seepage, even with damage to the top layer.
Additionally, BUR systems can be eligible for warranties or guarantees of up to 20 years, depending on the materials used and the system installed.
Reflective cap sheets are also available to reduce internal temperatures by reflecting the sun’s rays, thus lowering your energy costs.

- Raw BeatzOctober 2026
They do the best job for roofs and it’s a good price. Highly suggested to give them a call if you need roofing done
- Renee GreenOctober 2026
Brian was really upfront and offered a discount for my services. They called at 6:20 am , they were here at day break , My front porch roof was pulled up, And rain was ruining my front porch. I had 3 prior estimates .There's was the best deal for what was required. He was honest about my full roof which was done 5-7 years ago. It didn't need a full replacement like 1 company suggested and took pictures of the neighbors roof stating we gave them the wrong address. I didn't need a full roof like my neighbors. It did have some worn area's and they did what was needed. My only reason for not giving 5 stars is that when they were done they did not address me at all especially since they called at 6:20 am it would have been a 5 star if they let me know they were done and sent the completed work instead of me having to call and text b4 I got a response. It could have been done when they were finished. My only gripe . I went through each room in my upstairs to look for the ladder or the tech that I spoke to when they were on my front porch which I could speak with them right from my bedroom window to let me know when they were done to send me the photos of their done job. I was finally able to get to Brian the lead after a a phone call and text a bit later he was able to send the pictures and respond to my questions. Overall they did a great job. Just be sure to read the fine print of your contract!!
