Flat roofs are practical, sleek, and commonly found on commercial buildings and modern homes throughout New Jersey. Known for their minimalist look, low-slope roof styles efficiently use space, allowing for rooftop gardens, patios, and solar panel installations.

Low-Slope Roof Designs by Costello Roofing

At Costello Roofing, we specialize in high-quality low-slope roof installations, repairs, and replacements, ensuring that every roof is designed to endure New Jersey’s diverse weather conditions while maintaining structural integrity.

Key Benefits of Flat Roofs

Flat roof designs provide various benefits, making them an ideal choice for commercial properties and residential homes with a modern architectural style.

Maximized Space: Low-slope roof designs offer expanded usable space on top, which can be converted into functional areas or adapted for energy-efficient features like solar panels or green roofing.
Cost Savings: Flat roofs require fewer materials and less labor to install than pitched designs like gable or hip roofs, making them budget-friendly. They’re also easier to repair and maintain, helping reduce ongoing costs.
Modern Aesthetic: With their clean, streamlined look, low-slope roofs enhance contemporary home designs and commercial buildings with a minimalist, functional appeal.

Trusted Flat Roof Materials\s

To ensure long-lasting protection, we offer a range of durable flat roofing materials designed to protect your building without relying on slope:

EPDM Roofing Membranes: Known for flexibility and weather resistance, EPDM (ethylene propylene diene monomer) membranes are a popular flat roofing choice. This rubber material offers excellent UV protection and can withstand New Jersey’s temperature fluctuations.
TPO Roofing Membranes: TPO (thermoplastic polyolefin) membranes are both energy-efficient and resistant to punctures, UV rays, and chemicals. These single-ply flat roofing systems are an eco-friendly choice that reflects sunlight, helping to keep indoor temperatures down in warmer months.
Modified Bitumen Systems: Modified bitumen is an asphalt-based material reinforced with polymers for added durability. It is layered and secured with a torch-down method or adhesives, providing excellent waterproofing and strength. Modified bitumen is a dependable choice for flat roofs that require extra protection from New Jersey’s heavy rains and winter storms.

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!!
