Types of Modified Bitumen Roofing We Install

Styrene-Butadiene-Styrene (SBS) Modified Bitumen

• Flexible and elastic—ideal for areas with extreme temperature changes.

Atactic Polypropylene (APP) Modified Bitumen

• Rigid and highly heat-resistant—best for high UV exposure.
• Installed using a torch-applied method for exceptional waterproofing.

When your roof starts showing signs of wear—cracks, moisture buildup, or leaks—you need a solution that gets it back to peak condition fast. Ignoring these issues can lead to costly damage. 

We use secure scan technology and infrared thermography to detect hidden moisture and structural weaknesses before they become serious problems. Our 24/7 emergency repair services ensure that no matter when disaster strikes—whether it’s a storm, leak, or unexpected damage—we’re ready to respond.

Preventative maintenance is just as important as repairs. Regular checkups can extend your roof’s lifespan and help maintain energy efficiency, saving you money in the long run. 

Modified Bitumen Roofing Systems Pros and Cons

Choosing the right roofing system is a big decision, so let’s break down the advantages and potential drawbacks of modified bitumen.

Pros

• Highly durable and weather-resistant.
• Superior waterproofing protects against heavy rain and snow.
• Energy-efficient coatings reduce cooling costs.
• Easier to repair compared to single-ply systems like TPO.

Cons

• Requires professional installation for optimal performance.
• Torch-applied APP systems require safety expertise.
• Not as reflective as TPO, but coatings can improve energy efficiency.

Built-Up Roof vs. Modified Bitumen

Both BUR and modified bitumen are excellent commercial roofing options, but there are key differences:

• BUR consists of multiple layers of asphalt and gravel, making it heavier and more labor-intensive to install.
• Modified bitumen offers better flexibility and faster installation, reducing labor costs while maintaining strength and durability.

Modified Bitumen vs. TPO

If you’re comparing modified bitumen to TPO, consider your building’s needs:

• TPO is highly reflective and energy-efficient, making it great for reducing cooling costs. However, it’s more prone to punctures and tears.
• Modified bitumen is more puncture-resistant, making it a better choice for high-traffic areas or buildings that require frequent rooftop access.
