Reliable Low-Slope Roofing Services in Irwin and Pittsburgh, PA
At Bella Construction & Development Inc., we know that a good roof does more than just cover your building. It protects your property, keeps energy costs down, and adds value to your investment. We specialize in low-slope roofing, providing solutions for commercial buildings and homes alike. Whether you need a strong modified bitumen roof or a sleek metal roof, our team is ready to help.

What Is Low-Slope Roofing?
Low-slope roofing (also called flat roofing) is designed with a gentle slope, typically less than 3 inches of rise for every 12 inches of horizontal distance. This type of roof is common on commercial buildings, industrial properties, and some homes. While low-slope roofs offer benefits like easier access and a modern look, they also need special care to handle water drainage and other challenges.
At Bella Construction, we are experts in low-slope roofing systems. We make sure your roof can handle foot traffic, resist UV rays, and cope with temperature changes. Our goal is to provide you with a roof that lasts and helps you save on energy costs
Why Choosing the Right Low-Slope Roofing Matters in Irwin and Pittsburgh, PA
Choosing the right roofing material is key to making sure your roof lasts. The wrong choice can lead to leaks, costly repairs, and high energy bills. But with the right materials and installation, you can enjoy a roof that’s durable, energy-efficient, and attractive.
We offer a variety of low-slope roofing options to meet your needs and budget. Here’s a closer look at what we offer:

1. Built-Up Roofing (BUR): A Trusted Choice for Low-Slope Roofing
Built-Up Roofing (BUR) is one of the oldest and most reliable roofing methods. It’s made of multiple layers of asphalt and fabric, topped with gravel or mineral granules. This system is often used on commercial buildings and industrial properties.
Advantages:
- Waterproof: The layered construction helps keep water out.
- UV Protection: The gravel or granules protect the roof from the sun’s rays.
- Long Lifespan: With proper care, BUR can last up to 50 years.
- Fire Resistant: The top layer adds an extra level of fire protection.
- Ideal For:
- Large commercial buildings with wide, flat roofs.
- Industrial properties needing a tough, low-maintenance roof.
2. Modified Bitumen Roofing: Flexible and Strong for Low-Slope Roofing
Modified Bitumen Roofing is an asphalt-based material that’s been reinforced to make it more durable. It’s often applied in layers, using heat or adhesive to create a strong bond.
Advantages:
- Flexible: Handles temperature changes without cracking.
- Easy to Repair: If damaged, it’s simple to patch up.
- Weather Resistant: Built to withstand wind, rain, and sun.

- Low Maintenance: Requires little upkeep, making it cost-effective over time.
- Energy Efficient: Reflects heat, helping to reduce energy costs.

- Properties in areas with extreme weather, as metal is highly resistant to wind, hail, and fire.
5. Green Roofing Systems: Eco-Friendly and Attractive for Low-Slope Roofing
Green roofs involve growing plants on your roof, which helps with insulation and managing rainwater. These systems are becoming more popular for their environmental benefits and the natural beauty they bring to buildings.

Advantages:
- Seamless: The liquid creates a continuous, leak-proof surface.
- Flexible: Can be applied to many different types of roof materials.
- Easy to Maintain: Simple to recoat if needed, extending the life of the roof.
- Ideal For:
- Flat roofs with complex shapes needing extra protection from leaks.

Katie Zemba2025-05-27I recently had my roof and gutters replaced by Bella Construction and I couldn’t be happier with the results! From start to finish, the entire team was professional, efficient, and easy to work with. They took the time to explain the process, answered all my questions, and made sure I felt confident every step of the way. The crew showed up on time, worked hard, and completed the job faster than expected without cutting corners. The quality of the workmanship is outstanding—my new roof looks fantastic, and the gutters are working perfectly. They also made sure everything was cleaned up thoroughly afterward, which I really appreciated. I highly recommend Bella construction
