Roof Types We Serve at Costello Roofing: Gable, Hip, and Flat Roofs in New Jersey

Costello Roofing is certified by GAF, Owens Corning, and IKO, ensuring that we use roof materials that meet the highest standards. Learn more about the specific roof types we serve and how each design might suit your needs.

Gable Roofs

Gable roofs are a classic choice, known for their triangular shape that allows for effective water runoff and excellent ventilation. This roof style is ideal for New Jersey’s seasonal climate changes, as the slope helps prevent snow buildup in winter and sheds water efficiently year-round.

Our roofers bring precision and skill to gable roof repairs, replacements, and installations, using high-quality roof materials that stand up to both strong winds and heavy rains. Our team’s experience ensures that your gable roof will be durable, beautiful, and built to withstand New Jersey’s diverse weather conditions.

Hip Roofs

Hip roofs feature a gentle slope on all four sides, creating a robust, wind-resistant structure that works well in storm-prone areas. This design makes hip roofs one of the most stable designs, an excellent choice for New Jersey’s coastal regions.

With certifications from industry leaders like Owens Corning and GAF, our skilled team ensures that every hip roof installation and repair is done with the highest quality materials and industry-approved techniques. We understand the unique requirements of hip roofs, from proper ventilation to premium shingles that protect your home’s structure and enhance its curb appeal.

Flat Roofs

Flat roofs are common for commercial properties and modern residential designs, offering a sleek, minimalist look and creating opportunities for extra space, such as rooftop gardens or solar installations. However, flat roofs require specialized maintenance due to drainage needs, as they don’t naturally shed water.

Our team is well-versed in flat roof installations and repairs, using materials and techniques designed for optimal water resistance and long-lasting performance. We prioritize durability, ensuring that your flat roof will withstand New Jersey’s rainy seasons and continue to perform at its best.

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!!
