Modified Bitumen (Mod Bit)
Services

Modified Bitumen (Mod Bit) roofing is a popular choice for flat or low-slope roofs due to its durability, flexibility, and cost-effectiveness. At Arizona Roofers., we specialize in high-quality Modified Bitumen roofing solutions for both residential and commercial properties. Our expert team ensures that every Mod Bit roof we install provides superior protection and longevity.

Benefits of Modified Bitumen Roofing

Durability

Modified Bitumen roofs are highly resistant to extreme weather conditions, including high winds, hail, and heavy rain. They are also resistant to thermal shock and UV radiation.

Flexibility

The material is flexible, making it ideal for buildings with slight movements or those subject to temperature fluctuations. This flexibility reduces the risk of cracks and leaks.

10-year guarantee

We stand by our work with a 10-year workmanship guarantee, giving you peace of mind that your roof is built to last—with quality you can trust for years to come.

Easy installation

 Modified Bitumen can be installed quickly and efficiently, minimizing disruption to your property.

Energy efficient

 Available in reflective coatings, Mod Bit roofs can enhance energy efficiency by reflecting solar heat, reducing cooling costs.

Low maintenance

Once installed, Mod Bit roofs require minimal maintenance, saving property owners time and money over the long term.

Types of Bitumen Roofing

APP (Atactic Polypropylene) Modified Bitumen​

APP (Atactic Polypropylene) Modified Bitumen​

This type of Mod Bit roofing is modified with plastic (APP) polymers, making it more resistant to UV radiation and suitable for torch-applied installations.

SBS (Styrene-Butadiene-Styrene) Modified Bitumen

Modified with rubber (SBS) polymers, this type offers superior flexibility and is typically installed using cold adhesives or hot asphalt.

Modified Bitumen vs. Other Flat Roofing Systems

Modified Bitumen Vs. Built-Up Roofing (BUR)

Durability: Both systems are durable, but Mod Bit typically offers better flexibility and resistance to thermal shock.

Installation: Mod Bit is generally easier and quicker to install compared to the labor-intensive process of installing BUR.

Maintenance: Mod Bit roofs often require less maintenance than BUR systems, which can be prone to gravel displacement and membrane separation over time.

Cost: While both are cost-effective, Mod Bit can be more economical due to its simpler installation process.

Modified Bitumen Vs. Single-Ply Roofing (EPDM, TPO, PVC)

Durability: Mod Bit and single-ply systems both offer durability, but single-ply systems may offer superior resistance to certain chemicals.

Energy Efficiency: Single-ply membranes like TPO and PVC often have excellent reflective properties, but Mod Bit with reflective coatings can also achieve significant energy savings.

Flexibility: Mod Bit offers flexibility in varying temperatures, while EPDM can become brittle in cold weather.

Installation: Single-ply systems are typically faster to install, but Mod Bit’s torch-applied or self-adhered options can streamline installation while offering robust performance.

Modified Bitumen Vs. Spray Polyurethane Foam (SPF)

Durability: Both provide durable roofing solutions, but Mod Bit may have an edge in puncture resistance.

Maintenance: SPF roofs require periodic recoating, whereas Mod Bit roofs typically require less frequent maintenance.

Cost: Mod Bit is generally more cost-effective upfront compared to SPF, which can be more expensive due to the specialized equipment and expertise required for installation.

Amazing customer service with superb quality control. We were informed of all aspects of the roof installation with top notch communication from Bradley Crohurst. Videos and pictures were taken during the entire sequence. Competitively priced with the best products used in the business. The team took great care during the entire installation process. Extremely accurate and timely, starting and finishing as originally scheduled. I would highly recommend Bradley and his team for all of your roofing needs. Thank you for the tremendous service, Mike Lazar

I reached out to AZ Roof Co after being turned away by several other companies for a chimney repair. Jeff from their team came to my home, assessed the situation, and assured me they could handle the job — even quoting me for the work and telling me to “let people know AZ Roof Co took care of you when no one else would.” This gave me a lot of hope, especially after struggling to find anyone willing to help.

Unfortunately, after following up several times to schedule the repair, I was told by text, “Boss said no.” Not only was the job now off the table, but during the original visit, part of the chimney had been pulled apart without my consent — leaving it more exposed than before. When I raised this concern, I received an initial response from their COO, who apologized and said he would look into it. Despite my attempts to follow up and work toward a solution, they stopped responding entirely.

I don’t take leaving negative reviews lightly, but this was a disappointing experience. I was left with a partially dismantled chimney, no resolution, and empty assurances. I hope others have a better experience, but I can’t recommend this company based on how things were handled in my case.

From start to finish, we had a great experience with AZ Roof Co. Eric gave us our quote and explained so many details that I never would've thought of. (I always have 3 companies come and quote a job... Eric's presentation, the competitive price and great reviews made the decision an easy one) Jayda in the office kept me in the loop on scheduling and payment, color choices etc. Oscar and his team were on time & professional. And Pino was our final "walk through" making sure everything was as expected and we were happy with the job. I had one concern, and he got right on it and it was taken care of immediately. Highly recommend AZ Roof Co.

⭐️⭐️⭐️⭐️⭐️

We recently had our entire roof redone by AZ Roof Co., and I couldn’t be happier with the results. The new roof looks fantastic, and it’s backed by a 20-year warranty, which gives us so much peace of mind.

A huge shoutout to Pino, our Project Manager—he was truly a pleasure to work with. He was incredibly accommodating with our schedule, kept us informed every step of the way, and was always kind and professional. You could really tell he cared about the quality of the work and our overall experience.

There was a small mishap during the project where something fell and damaged one of our outdoor tables, but I want to emphasize how impressed I am with how the team handled it. They immediately took responsibility and are going above and beyond to make it right. That level of accountability and customer care is rare and very much appreciated.

I highly recommend AZ Roof Co. to anyone in need of roofing work. Excellent service, beautiful results, and a team that truly stands behind their work!
