When it comes to choosing a roof for your New Jersey home, the decision between flat and pitched roofs is one of the most important architectural choices you’ll make. This choice affects not only your home’s appearance but also its performance, maintenance requirements, and long-term value. At American Supreme Construction, we’ve helped countless New Jersey homeowners make this critical decision, and we understand the unique factors that influence roof selection in our state’s diverse climate.

Understanding Roof Types: Flat vs. Pitched

What is a Flat Roof?

A flat roof, despite its name, has a very slight slope (typically 1-10 degrees) to allow for water drainage. These roofs are characterized by their horizontal or nearly horizontal surface and are commonly found on modern, contemporary, and commercial buildings.

What is a Pitched Roof?

A pitched roof has a noticeable slope (typically 15 degrees or more) and includes various styles such as gable, hip, mansard, and gambrel roofs. These traditional roof designs are more common in residential construction and offer distinct advantages in certain climates.

New Jersey’s Climate and Roofing Considerations

Weather Challenges in New Jersey

New Jersey’s climate presents unique challenges that influence roof selection:

Precipitation Patterns:
