"From the first call to the final cleanup, the process was seamless. They provided a same-day estimate and had our new roof installed just a few days later. The crew was fast, professional, and left our property spotless. Highly recommended!"

Types

The Advantage of a Multi-Ply System

The exceptional durability of Modified Bitumen is due to its multi-ply, reinforced design, making it the premier choice for demanding commercial roofing environments.


🔗 Engineered for Toughness


This system is renowned for its outstanding resistance to punctures and tears. By blending layers of rubber-modified asphalt with a strong reinforcing fabric (like polyester or fiberglass), it creates a membrane that can withstand heavy rooftop equipment, regular foot traffic from maintenance crews, and the impact of dropped tools.


🔗 Seamless Sealing for Complex Roofs


For commercial roofs crowded with vents, pipes, skylights, or drains, Modified Bitumen is an ideal solution. Its flexible and robust nature allows our technicians to expertly form the material around every penetration, creating a durable, completely watertight seal at your roof’s most vulnerable points.


🔗 Flexible Installation Options


Modern Modified Bitumen systems offer a range of application methods, allowing us to select the safest and most effective technique for your specific building. We can utilize cold-applied adhesives to avoid open flames, or apply the material using the traditional heat-welded (torch-down) method, ensuring the ideal installation for your property.

FAQ's

Frequently Asked
Questions

Here you’ll find a compilation of the most frequently asked questions. If there’s something you want to know which isn’t here, please send an email to office@threesonsroofing.com.
What makes modified bitumen a good flat roof choice?

It’s durable and flexible. Oahu’s heat won’t make it brittle, and Delmarva’s freeze-thaw cycles won’t crack it.

How long can a modified bitumen roof last?

With regular inspections, 20 years or more. Salt air in Oahu may shorten lifespan slightly, while snow loads in Delmarva mean extra care extends its service.

Is modified bitumen easy to repair?

Yes. In Oahu, small heat cracks can be patched. In Delmarva, storm-torn seams can be resealed without replacing the whole roof.
