Modified Bitumen Roofs by Costello Roofing: Built for Strength and Stability

Though the name might sound intimidating, this type of flat roof system is equally protective over residential homes as commercial or industrial buildings. If your garage or home has a modern low-slope design, consider calling the Costello team for information about layered roof systems like this for your New Jersey home!

How Bitumen Membrane Roofing Works

Like asphalt shingles, this robust flat roofing material is made of a fabric membrane dipped in asphalt reinforced with polymers, enhancing flexibility and strength. Installed in layers, it’s an excellent choice for commercial and residential low-slope roofs that need added waterproofing. Modified bitumen is applied using adhesive or heat-welding techniques, creating a reliable seal against water and other elements.

Benefits of Modified Bitumen Roofing

Waterproofing: Multiple layers create a secure, water-resistant surface.
Durability: Resilient to temperature shifts and impact, modified bitumen withstands tough conditions.
Flexibility: Adaptable to different configurations, ensuring a precise fit on your flat roof.
Longevity: Modified bitumen roofs can last 20 years or more with regular maintenance.

These guys are the absolute best for roofing in South Jersey. I appreciate this local family company that came through when we needed a roof repair done.Prior to calling Costello, my neighbors had their roof done by Veterans roofing. I spoke with them while they were working next-door and got a quote for work they would do on our house. Later, I spoke again with an employee who was flying a drone and he totally blew me off again. My texts were ignored for weeks. Finally, I called and spoke with Veterans and they promised they’d be out that afternoon - no show.So I gave up and called Costellos. Not only did they come when they said they would, they also matched Veteran’s quote and worked with my insurance so I didn’t have to. Ryan was our company rep and his boss, Damien, also helped us out. I can’t say enough good things about them and their service. I appreciate their respect of my time and concern for my issue. Highly recommended. Thank you Costello Roofing!

After shopping around for a roof replacement and talking to 8 roofers and meeting with 6 estimators, we chose Costello Roofing. It boiled down to my frank conversation with Ernie, his understanding of our issues and his follow-through. The crew arrived, worked diligently on the tasks, and were extremely polite and were wonderful dealing with the dogs needing to go out. They cleaned up the yard and did a great job. We are very happy with the end result. Thank you!

Had a great experience with Ted and the Costello team. Their price was competitive with the other companies I priced and Ted went above and beyond to work around my hectic schedule and get my job done in a timely and efficient manner. The crews worked extremely hard from dusk till dawn.

Costello Roofing Put a new roof on my house last year, And they did an excellent job so when I needed new gutters, I considered using them again. I worked with Ted from the Costello sales team. And he was very good at explaining the process, the materials, and what I will be getting for the price I would pay. I would recommend them if you want to get a quality job at a fair price!

They are great from the very start. When Mike came out to give me an estimate you could tell he’s a man that stands by his company. He answered all of my questions and explained exactly the project in great detail. When it came time to do the job, Mike was also there on the roof making sure his guys were well prepared to make the job run as smooth as possible. And that it did!! I will continue to use Costello roofing for all my future projects!!
