Commercial Modified Roofs

Modified bitumen (mod bit) roofing is a durable and cost-effective solution for commercial buildings with flat or low-slope roofs. Originally developed in the 1960s as an improvement to traditional Built-Up Roofing (BUR), modified bitumen has become a trusted industry standard thanks to its flexibility, weather resistance, and long lifespan. 

Whether you need a new installation, repair, or roof restoration, Azul Roofing specialized in modified bitumen for commercial buildings in Arizona.

What Are Commercial Modified Roofs?

Modified bitumen combines an asphalt membrane with polymerized rubber or plastic and fiberglass reinforcement. The result is a roofing material that provides superior waterproofing, impact resistance, and longevity.

Benefits of Commercial Modified Roofs

Modified bitumen has become a go-to choice for commercial properties thanks to its many benefits:

multi layer icon (1)

Multi-Layer Protection

Mod bit is usually applied in two or more layers to create a reinforced, highly durable roofing system that stands up to the elements and extends your roof’s lifespan.

Superior Tear & Impact Resistance

Thanks to its high tensile strength, most modified bitumen roofing resists punctures, tears, and damage from wind-driven debris, storms, and regular foot traffic. This makes it ideal for commercial buildings with rooftop access.

Exceptional Waterproofing

Mod bit roofing creates a seamless, watertight barrier that prevents leaks, even with Arizona’s monsoon rains. Multi-ply systems provide an extra layer of protection against moisture intrusion.

Energy Efficiency

Certain modified bitumen systems include cool roofing technology that reflects sunlight and improves insulation. This can help your business lower cooling costs and improve energy efficiency.

Weather & UV-Resistance

Mod bit is built to perform in Arizona’s harsh climate, able to withstand extreme heat, heavy rain, and strong winds. Some systems include reflective coatings that deflect UV rays to reduce heat absorption and extend the roof’s lifespan.

Easy Installation & Maintenance

Modified bitumen is relatively quick to install and, as a rolled membrane, is simple to repair if damaged. Its layered structure allows for easy patching and restoration – meaning less long-term maintenance costs.

Commercial Modified Roofs Installation Types

There are several ways to install a modified bitumen roof, depending on your building’s structure, climate considerations, and project requirements.

Type 1: Torch-Down Application (most common)

This is a highly durable method where roofing layers are heated with a torch to bond directly to the underlayment. This creates a watertight, seamless seal that offers excellent resistance to UV rays and moisture infiltration. 

Type 2: Cold-Adhesive Application

This is a low-heat alternative that uses specialized adhesives to secure the roofing layers. This method is ideal for buildings where open flames or heat application aren’t feasible.

Type 3: Self-Adhering (Peel-and-Stick) Application

This is a cost-effective option where mod bit sheets come with a pre-applied adhesive backing. It’s quicker to install but is less durable than torch-down or cold-applied systems, making it more suited for temporary solutions.
