What is a Modified Bitumen Roofing System?
Modified bitumen roofing is a strong and long-lasting roofing option that has become very popular. It started in the 1960s as an alternative to traditional roofing systems. Now, it’s one of the top choices in the U.S2.. This system has many layers, like insulation and membranes, making it strong and protective2.
Multiple Plies and Greater Thickness
Modified bitumen roofing stands out for its many layers and thickness. A typical 2-ply system is over 240 MILS thick, much thicker than a single-ply roof3. These extra layers make it very durable, lasting about 20 years42.
This thickness and layering also make it strong against bad weather like extreme temperatures and heavy rain4. It’s a great choice for places that get a lot of use3.
There are two main types of modified bitumen membranes: APP and SBS. APP is great against UV rays, while SBS is flexible for areas with big temperature changes2. Self-adhered membranes are also popular for being easy to install and safe from fire hazards2.
In short, the many layers and thickness of modified bitumen roofing make it a top choice for its benefits and performance423.
Durability and Performance
Modified bitumen roofing is known for its strong layers and thickness. This makes it very durable in places with a lot of foot traffic5. Its thickness and multiple layers make it reliable against different weather conditions5. It also stays flexible and handles extreme temperature changes well, perfect for roofs with a low slope5.

Modified bitumen roofing has many benefits, but there are some downsides to consider. One big issue is how it absorbs heat in the summer. Its dark color can make buildings hotter, which can increase cooling costs11.
Absorption of Heat in Summer
Manufacturers now offer solutions to this problem. They provide reflective cap sheets or lighter colors. These options help reduce heat and keep buildings cooler11.
Higher-Risk Application Methods
Applying modified bitumen roofing can be risky, especially the torch-down method. It needs special skills and safety steps to avoid fires. Owners should pick experienced contractors who know how to install these roofs safely12.
Also, modified bitumen roofs have more layers than single-ply ones, which can make them more expensive upfront. But, they last longer and perform better, making them a good value12.
