Modified Bitumen Roofing

Modified bitumen flat roofs are a popular choice for residential, commercial, and industrial properties due to their durability and cost-effectiveness. At Tridom Roofing, we specialize in providing top-quality modified bitumen roofing solutions tailored to meet your specific needs, ensuring long-lasting protection and performance.

What is Modified Bitumen Roofing?

Modified bitumen roofing is a type of asphalt-based roofing system designed for flat or low-slope roofs. This roofing material combines traditional roofing asphalt with modern polymer technology, resulting in a highly durable and flexible roofing solution. Modified bitumen roofs are known for their excellent weather resistance, UV protection, and ease of maintenance, making them a preferred choice for many property owners, especially for those seeking an industrial design aesthetic.

Types of Modified Bitumen Roofing Membranes

SBS (Styrene-Butadiene-Styrene)

SBS, often termed “rubberized asphalt,” combines asphalt with polymerized rubber to create a highly elastic and flexible membrane. This type of membrane is perfect for roofs that experience significant temperature fluctuations and strong winds, providing superior resilience and durability.

APP (Atactic Polypropylene)

Known as “plastic asphalt,” APP is made from asphalt blended with plasticized polymers, which expand under higher temperatures. APP membranes are particularly valued for their enhanced UV resistance compared to SBS, making them an excellent choice for areas with intense sunlight exposure.

Benefits of Modified Bitumen Roofing

Exceptional Durability

Known for its high tensile strength, modified bitumen roofing resists punctures and tears caused by storm damage, wind-driven debris, and foot traffic, ensuring long-lasting protection.

Superior Waterproofing

Modified bitumen roofs provide outstanding waterproofing, especially when installed as multi-ply systems, safeguarding your property against water infiltration.

Energy Efficiency

With excellent UV resistance, modified bitumen roofing systems contribute to significant energy savings by reducing cooling costs and enhancing overall energy efficiency.

We have a Long History of Happy Clients

The work was performed efficiently, and the clean up was meticulous. They even replaced an old skylight with a new one and did not change the price. They give you a report with project photos of the entire process and completed roof at the end of the installation and go through a walk around check list. Their people were so good I hired them to install new rain gutters and some other wood replacement on the house we recently purchased. I highly recommend this company. Well worth every dollar I spent on the quality work I contracted them to perform.

Doug Y.

We were very pleased with the quality of materials used and the workmanship. We liked the fact that there was a project manager on site the entire time the crew was working. Also, impressed with the cleanliness of the job site and that all debris was picked up. Project Manager answered any questions we had regarding the work in progress. Work was completed in two days! Love the results! Have referred them to our neighbors and others!

Barbara B.

Tridom Roofing was always very professional in every way. Their representatives were well spoken and followed up on their words. The personnel on the job were courteous and knowledgable about their jobs and the materiels being used. Tools used on the job were always top of the line and any tools not on hand were quickly obtained for the workers. I always felt that Tridom Roofing was working for me and was not just for getting a job done and get paid.

Eugene G.

I had my roof replaced about 14 years ago by one of the most respected roofers in the Houston area and I expected it to last longer, especially after it took them 5 days to install, but I began to see some rotting wood and a leak. I called original company and was not impressed with their response. One call to Tridom was all it took and I had not only a new roof, but a understanding of what was not done correctly with previous company. Odd thing for me to say…but I TRUST these folks.

Vaughn G.

They did outstanding work. My neighbors are haters now. They did a real good job. They have done several roofs in my neighborhood but ours is the nicest one.

Sperancita W.

The man who was in charge of organizing everything, Johnston, was really amazing. He communicated well with us. He explained things well. For being a younger man, he managed his staff of older men very well.

The crew was very professional. And the guy that I dealt with (Chris Y.) blew me away. He completely dissolved my initial feelings about contractors. He was amazing. He communicated exceptionally well, and reassured me when it came to dealing with the insurance company.

Gloria M.

From the salesman, Johnston Camp to the finished production was a wonderful experience. I would do it again.

Eileen G.

Very professional. Kept in constant contact either via calls or texts. Responded to calls and texts within minutes and always very courteous and professional. Provided progress pictures and explained EVERYTHING thoroughly. Was told originally would be a 2 day project, but they were able to complete it all in one day. Johnston Camp is an asset to this company!! I couldn’t be any happier with him or the work completed. I will definitely recommend them to anyone looking.

Kristina F.

I have tried to get my roof replaced for over a year. I worked with 3 other companies. Tridom was the only one who understood my needs. They were meticulous. They did the job in one day. They left the yard cleaner than before. I have the best looking roof in my neighborhood.

Jeffrey W.

My experience with Tridom Roofing and everyone on their staff couldn’t have been more of a pleasure even during a tough time. They were there for me when my roof got ripped off my house when the tornado swept through San Antonio. Not only did they put a roof over my family’s head they did a dang good job.

They were very professional and did an excellent job on our roof. I also appreciate that our home was able to be completed in one day. Thank you to all of the crew members and the staff that completed the job for us. It looks great!

Lisa Martin

The process what’s seamless. I had my whole roof replaced and they did everything from explaining how to work with the insurance company, doing the work while I was away, hiring at and all subs all the way to project completion. They were a great pleasure and constantly communicated as much as I needed to. Amazing work.

Carlos Longoria

I was looking for quality at a fair price. Roofs are expensive, so I wanted to make sure that I worked with a company that I felt I could trust and not be taken advantage of. Tridom met those goals. I would recommend them to others.

Lee Brockinton

I was very pleased with this roof installation. The workers were very conscientious and produced a high quality install . Also, the crew supervisor Will Hatchell did a great job answering all my questions and made sure that everything I wanted done was completed as discussed prior to the start of the job. Usually contractors can be difficult to communicate with , but Hatchell was very responsive and made sure that I was completely satisfied at the end of the job. Recommend very highly!

Ralph Casazza

Tridom Roofing did a great job installing an entirely new roof on my home. Big thanks to my project manager Will Hatchell. He made the process extremely seamless and easy. He was there when the adjuster came to inspect, and took care of everything regarding the claim process. He provided a reasonable quote, and he and his crew were on time and the work was terrific.

I appreciated the open communication to explain exactly when and what the process and installation would entail. Will and his crew were very knowledgeable, professional, courteous, fast, efficient and provided high quality work. They even did a very thorough clean up after the job! They went above and beyond what was promised for the job. You can tell they take a lot of pride in their work. I highly recommend them for any of your roofing needs.
