Understanding Modified Bitumen Roofing
Modified Bitumen Roofing is an asphalt-based flat roof material system that has been enhanced with polymers to improve its flexibility, elasticity, and resistance to extreme temperatures. It’s an excellent choice for flat roof applications due to its proven durability and ease of maintenance.

Five-Star Roofing: What Our Clients Say
“Great team. Solomon is great.
He was great at fixing all the minor issues and making up any work that was not completed. I did not have a rush schedule, but when rain was coming, the Astro team jumped into action!
I had lots of little modifications with drains and soffit, creating that they didn’t mind doing, and made it look great!
Grazie mille Solomon and Dario!!!!!”

-Shawn C.
Shafter, Oakland, CA


“I wanted to share what an amazing experience I had with Astro Roofing.
From the estimate to the construction and afterwards, Salomon and Dario were professional, prompt, and tidy.
I highly recommend getting multiple quotes, but be assured, Astro Roofing was very competitive. They outlined everything included in replacing the roof. There were two change orders (solar roof fans and gutter guards) that I’m very glad I purchased. Doing this during a roof replacement lowered the cost and made for a simple and quick installation.
I very rarely say this, but if I could give six stars, I would.“

-Marty L.

“They were timely, professional, and clean.
Salomon and his team were awesome.
I was doing a full roof replacement and found them on Yelp. They came out quickly to give a quote. Answered all my questions quickly and with a high level of detail. Worked with me on scheduling to find a time that worked for us.
When they came onsite, they were timely, professional, and clean. They kept me up to date on progress and completed the job with no issues in 3 days.
I would strongly recommend them!

FAQ’s About Modified Bitumen Roofing
What is Modified Bitumen Roofing?
Modified Bitumen Roofing is an asphalt-based roofing system that has been enhanced with polymers. These polymers give the asphalt added flexibility and elasticity, making it more resilient to extreme temperatures and temperature fluctuations. It’s designed for low-slope or flat roof applications, offering a durable and waterproof membrane.
How long does Modified Bitumen last?
With proper installation and maintenance, a Modified Bitumen Roofing system can last between 20 to 30 years, and sometimes even longer. Factors such as the quality of the flat roof material, climate, and adherence to maintenance schedules all play a role in its overall lifespan. Regular inspections help maximize its durability.
Is Modified Bitumen good for flat roofs?
Yes, Modified Bitumen Roofing is an excellent choice for flat roof applications due to its inherent flexibility and strong waterproofing capabilities. It’s designed to perform well on low-slope roofs where water drainage might be slower than on pitched roofs. Its durability and ease of repair make it a favored flat roof material.
Can I apply a coating to Modified Bitumen?
Yes, applying a flat roof coating to a Modified Bitumen Roofing system is highly recommended. Coatings can extend the roof’s lifespan by protecting it from UV radiation and harsh weather, improving its energy efficiency by reflecting sunlight, and enhancing its overall performance. This coating acts as an additional protective layer.
What causes Modified Bitumen roofs to fail?
Common causes of Modified Bitumen Roofing failure include improper installation, inadequate drainage leading to standing water, punctures from foot traffic or debris, and prolonged exposure to extreme UV rays without proper protection like a flat roof coating. Regular maintenance and prompt repairs are crucial to prevent these issues.
