Built-up roofing is also known by BUR and is the most popular type of roofing material applied to low-slope roofs. It is made from alternating layers of reinforcing material and asphalt (bitumen) and is completed with a top coat of stone or gravel.

The use of BUR in low-slope or “flat” roofs is preferred because it constitutes a continuous sealed covering. The difference between BUR and roof shingles is that the shingles are not sealed and need a steep roof slope to discard water completely.

This type of roofing is not new, but the material and its base have developed during that time. Current built-up products include a rigorous insulation layer for increased energy efficiency.

Most built-up roofs are made of three components: bitumen supply, ply sheets, and one or more surfacing materials that can be stone or gravel.

The bitumen can be either “hot,” implying it is heated so that it dissolves during installation, or it can be “cold,” which resembles an adhesive.

Cold BUR can be spattered or applied with a type of mop, and it does not release toxic residues through the application. The cold built up is not conditioned by weather and also grants better performance than the hot one.

I had hail damage done to my roof and Alex and the rest of the team were wonderful answering any questions I had. We are very pleased with our new roof and satisfied they are there for us if we have any issues down the road.

By far the best company I have done business with in a long time. The price was good for all the work involved and quality materials. They have options for financing that others don't offer. David and Diego have superb communication skills and responded to every phone call. Very meticulous with Parker's supervision on site during all the installation process including the cleanup. I highly recommend them. This company exceeded my expectations and went the extra mile to make sure I was completely satisfied and happy with the entire job. The crew was also great . Well mannered and respectful. My neighbors even commented on how quiet and professional they worked. Great team and company. God bless and great success. 👏👍

These guys were the key component in a very favorable roof damage insurance experience. I would use them again in a heartbeat. Knowing we have little kids they even sent a guy to do an additional sweep of construction nails around the house a day later just to make sure cleanup was done right. All quotes and costs were accurate and everything done in a timely manner. I had little experience with my insurance provider but these guys help answer all those questions and made communication seamless. Job well done! God bless

These guys were fantastic. Great sales team, professional and fast installers! This whole stressful process was made incredibly easy by these guys. 100% would recommend them to anyone. Unfortunately my insurance would not cover or even help with the cost of my new roof. Roofers LLC ended up doing my roof for $8000 less than I thought I was going to have to pay. I’m beyond happy and impressed.

Excellent service from beginning to end. Our roof had storm damage. Kenny came out, did inspection and met with insurance adjuster. Replacement was approved. The crew that did work were professional, showed up on time and finished in a timely manner. The property was immaculate when they left. Parker was very accommodating and a pleasure to work with. Great experience! Thanks to you all.
