Modified Bitumen Roofing Installation Process

We focus on careful evaluation, quality materials, and precise installation techniques to give your flat roof lasting protection. Each step is key to making sure your new roofing system meets your building’s needs and stands up to weather and wear.

1. Site Assessment and Inspection

We start by thoroughly inspecting your roof. This includes checking for damage, leaks, and the condition of the existing materials. We also look at the roof’s structure to confirm it can support the new modified bitumen layers.  Our team measures the roofing area precisely and examines drainage to prevent water buildup. We note any areas that need repair or special attention before installation begins. This step helps us plan the installation process correctly and avoid surprises during work. It ensures the finished roof will perform well under your local weather conditions.

2. Material Selection and Preparation

Choosing the right materials is key for a lasting roof. We use modified bitumen membranes made from asphalt mixed with modifiers like rubber or plastic. These improve flexibility and durability. Depending on your roof type and budget, we select specific membranes. Some are torch-applied, while others use cold adhesives. We prepare all materials on-site by cutting membranes to fit and gathering necessary underlayments. Proper preparation allows us to start installation quickly and reduces the chance of errors. It also ensures every piece fits perfectly for a tight, protective roof.

3. Installation Techniques and Method

We use proven techniques tailored to your roof type. Torch-applied installation involves heating the membrane with a torch to create a strong bond. This method offers excellent waterproofing and durability. Cold-adhesive installation uses specialized glues to stick the membrane down. This method is safer for certain buildings and climates. In some cases, we may use self-adhered membranes with sticky backings.


Before installing membranes, we apply a base sheet for added strength. We then layer membranes with seams tightly sealed to stop leaks. Finally, we finish with protective coatings or gravel where needed. Throughout installation, we follow safety rules and quality checks to make sure the roof holds up well over time.

Overview of Modified Bitumen Roofing

Modified bitumen roofing is a popular choice for many commercial buildings with flat or low-slope roofs. It offers durability, ease of installation, and reliable waterproofing. You’ll find it is built to handle foot traffic and harsh weather.

What Is Modified Bitumen Roofing?

Modified bitumen roofing is an asphalt-based roofing system designed for flat or nearly flat roofs. It combines asphalt with rubber or plastic polymers, which makes the material more flexible and stronger than traditional asphalt roofing.


The system usually comes in rolls that are applied with heat or special adhesives. This process fuses the layers together, creating a tough, continuous roof membrane. Its layered design often includes reinforcing fabrics, which add to the roof's strength.

Comparison With Other Commercial Roofing Systems

Compared to TPO and PVC roofing, modified bitumen roofs are thicker but usually have a shorter lifespan. They offer more durability than built-up roofs but may not last as long as the newest single-ply membranes.


Unlike some roofing types, modified bitumen performs well in colder climates because it won’t become brittle. However, it may require more maintenance than some thermoplastic options. Each system has trade-offs, but for many commercial buildings, modified bitumen strikes a good balance between cost, durability, and ease of installation.
