What is Modified Bitumen Roofing?

Modified bitumen roofing is among the most common options for commercial roofs. The system has been used as a standard roofing asphalt solution since the 1970s. Modified bitumen was developed to offer maximum protection with the least maintenance needs. Today, a modified bitumen roof represents the highest-end roofing solution. Modified bitumen roofing systems come in two main categories; atactic polypropylene (APP) and styrene-butadiene styrene (SBS).

The SBB is a more cost-effective roofing system. It is heat welded, or torch applied to look like plastic. On the other hand, the SBS roof system offers more impact resistance and temperature tolerance. It’s installed using a hot mopping method that uses asphalt or a cold process adhesive, ending in a rubber-like surface. Both systems are great for commercial roofing. They are both quite resistant to impact and weather fluctuations. Because of its complex nature, you will need the best contractors to have it successfully installed. This roof will make your house look beautiful, but only if the contractor knows what they are doing.

We provide essential maintenance to all customers!

A Brief History

The name modified bitumen comes from the “modifiers” added to the base material, which is a bitumen. Thermal catalysts are used to make it stronger and more adhesive. It also makes installation possible. The modifiers add durability to the benefits of these roofs. Common asphalt is strengthened more using these modified, also improving the general quality of the material. Modified bitumen membrane works just like other flat roofing options in terms of insulation. However, it’s more effective. If proper construction methods are followed, you are looking at the most energy-efficient roofing solution.

Through extensive research I had found San Diego County Roofing and Solar for my roofing needs. Being that I also have solar panels that needed to be removed and replaced that was a plus. San Diego Roofing and Solar provided us with a above reasonable quote, and they performed their duties with above and beyond expectations. I found them to be professional, honest, dependable and efficient. Their team worked like clockwork on completing the job on time. Each day the team clean up whatever debris they had made that day. They were very detailed throughout the whole process. Communication was unsurpassed. We are aware there are many roofing companies out there and I believe I had found the best. San Diego County Roofing and Solar deserves 5 Stars, and I would not hesitate to use them again

SD County Roofing did a great job. I had a complete re-roof but also had to do fairly extensive ventilation work. Other roofers did not want to do the work as they said they didn't have the expertise. SD County Roofing came to the house, went into the attic/crawl spaces and designed the solution. Prior to the new roof my attic and crawl spaces were extremely hot because they couldn't ventilate properly. The attic temps created extremely warm conditions throughout the entire house. After the new roof and attic work I am happy to say the attic, second floor, and the entire house is significantly cooler! The roof looks great too.

San Diego County Roofing & Solar was a fantastic company to work with. They provided a free quote, with full explanation of all the pieces included. They answered all of my questions and NEVER pressured me into anything. They did a lift of my concrete tile roof, replaced broken roof tiles, replaced the roof under the tile and also replaced rotted wood as needed. As the project progressed, they provided excellent communication! I also had them replace three skylights with new energy efficient ones. It was so exciting to have a roof that doesn't leak during these last rains. I also am working with their solar division to get solar installed. The discussion of options without a high pressure sales pitch from a solar company has been such a great experience. I highly recommend them if you are looking for a professional roofing company. They are outstanding!!

We had our roof replaced last week and our experience was exceptional. San Diego County Roofing had a great crew who clearly worked well together and knew what they were doing. Very efficient and tidy; they picked up everyday following their work. Troy and Edgar were both easy to talk to and responsive to any questions or concerns. Highly recommend.

We had a great experience with SDCRS. From start to finish they were very professional. They estimated the roof replacement to be 4 days and they knocked it out in 3 day, working long hours. There was lots of debris from removing the old roof and after each day they cleaned up everything and left our yard looking like they had not even been there. Shout out to Dillon for the great communitcaton and getting us a quote in a timely manner, as well as a big shout out to Edgar who managed the onsite roof replacement. He was very professional, kind and kept great communication the whole time on the status of the roof. Again, they finished early and left our home looking amazing everyday. The roof looks great and we are happy we went with this company. We'd highly recommenend SDCRS!

You need the best roofing company to get the most from modified bitumen roofs. These are roofs that require complex approaches like the subzero cooling process. That might make the entire job a bit challenging. If done right, bitumen roofing is the best choice both for commercial and industrial roofs. A well built-up roof promises the following benefits.

Affordable and Energy Efficient

Installing Bitumen is quite easy if the contractor understands what they are doing. Materials like gravel are also easily available. This can significantly reduce the cost of putting up these roofs.

Durable and Reliable

Durability is one of the reasons bitumen roofing is the best choice for many people in San Diego. You won’t be calling a contractor to get the shingles repaired any time soon once installed. And it will serve you for many years.


Unlike standard PVC and TPO, modified bitumen roofs are quite versatile. They will fit right on almost any roof with very minimal difficulty. Most roofing contractors recommend this method because it offers customers an easy option.

High Resistance

It can be relatively expensive when roofing your building initially with modified bitumen. But the highest costs come from using the roof. After years, issues with heat and expensive inspection may require a lot more. That is why you need a roof that is more resistant and durable. Modified Bitumen is certainly such a material.
