Waterproof Membrane Systems for Flat & Low-Slope Roofs
Modified Bitumen Roofing in Florida
Durable, Layered Roofing for Florida’s Flat Roofs
Modified Bitumen Roofs Installed the Right Way
Modified bitumen roofing offers reliable waterproofing and strength for flat and low-slope structures. RoofNuts installs both torch-down and self-adhered (peel-and-stick) systems to suit your building and budget. Whether you need a new installation, repair, or full replacement, we build each layer to withstand Florida’s sun, storms, and humidity.
A Time-Tested System That Still Performs
What Makes Modified Bitumen a Strong Choice?
Modified bitumen combines the durability of built-up roofing with the flexibility of modern membranes. Its layered structure resists tearing, absorbs impact, and handles extreme temperatures. For Florida buildings that need dependable performance without high-cost complexity, this system checks all the boxes.

Commercial & Residential Applications
Modified Bitumen for Every Flat Roof
From office buildings and restaurants to garages and home additions, modified bitumen is a flexible solution for many Florida structures. RoofNuts installs SBS and APP systems based on your roof’s slope, structure, and exposure. Whether you're building new or replacing an old membrane, we provide a weather-ready, long-lasting installation you can count on.
Built for Florida’s Code and Climate
Roofing That Holds Up in Heat and Hurricanes
Florida roofs need more than just waterproofing — they need to survive tropical storms, UV radiation, and heavy downpours. Our modified bitumen systems are installed with proper slope, venting, and flashing to prevent ponding and premature wear. We follow all Florida building codes and apply systems that pass inspection and outlast the elements.
Multi-Layered Systems That Work Together
We Install Bitumen Roofs With Detail and Precision
Modified bitumen isn’t a one-size-fits-all roof — it’s a layered system that requires careful installation. RoofNuts ensures every base sheet, cap sheet, and overlap is secured, sealed, and vented to prevent water intrusion. We handle both torch-applied and cold-process builds, depending on what your building allows. The result: a tough, clean, code-compliant roof.
Why Modified Bitumen Works for Florida
UV & Heat Resistant: Built to reflect solar radiation and hold up in Florida sun.
Strong Seam Sealing: Torch or adhesive application bonds sheets with watertight seals.
Multi-Layer Protection: Multiple layers reduce leak risks and improve durability.
Flexible Material: Absorbs thermal movement without cracking or shrinking.
Easy to Maintain: Seam repairs and resurfacing can extend system life affordably.

Modified Bitumen Roofing Questions Answered
Florida Flat Roof FAQ – Bitumen Systems
Still deciding if modified bitumen is right for your building? Here are answers to the questions we hear most.
How long does a modified bitumen roof last?
With proper installation and maintenance, these systems typically last 20–25 years in Florida conditions.
What’s the difference between torch-down and peel-and-stick?
Torch-down is heat-applied and very durable. Peel-and-stick is a safer, cold-applied option used where open flames aren’t allowed.
Can you re-roof over an old flat roof with bitumen?
In some cases, yes — but we always inspect the decking and existing layers before recommending that approach.
Is modified bitumen waterproof?
Yes. It’s a multi-layered waterproofing system designed for flat or low-slope roofing applications.
