MODIFIED BITUMEN ROOFING
MADISON PRO ROOFING

What is Modified Bitumen Roofing?

Modified Bitumen is a rubber- or plastic-polymer-modified asphalt-based roofing product that provides extra flexibility, durability, and weather resistance. It's utilized for flat and low-slope roofs and is frequently applied to commercial and industrial buildings in Madison and Illinois.

Modified Bitumen is sold in roll format and generally laid in multiple plies, torched down, cold-applied, or self-adhered. Due to its reinforced configuration, Modified Bitumen is the preferred roofing option for buildings with expected foot traffic, impact, or temperature fluctuation.

Modified Bitumen Roofing Installation

We begin with a complete inspection of your roof deck, slope, and insulation needs. Depending on your building and application requirements, we suggest either a two-ply or multi-ply system, and select the appropriate installation method—torch-applied, cold adhesive, or peel-and-stick.

✅ Ideal for industrial and commercial facilities with pedestrian traffic
✅ Can be applied in layers for extra waterproofing and durability
✅ Integrates well with insulation upgrades and cool roof surfacing

Modified Bitumen Repair & Maintenance

While strong, modified bitumen roofing also needs to be inspected periodically for:

• Seams splitting or cracking

• Puncture by equipment or pedestrian traffic

• UV degradation or blistering

• Loss of flashing and adhesion of membrane

Heat-welded patch repairs, surface re-coating, and regular preventive inspections are offered by us to ensure your roof is sealed and secure throughout the year. Building owners also have many insulating options—some apply cool roof coatings over their bitumen to save energy and increase the lifespan of the membrane.

Modified Bitumen Roofing Cost

The cost of modified bitumen roofing depends on the number of plies, method of installation, insulation layers, and condition of the overall roof. It's not the least expensive option but a mid-range system that provides great durability and value.

We provide free on-site inspections to assess your building and provide an open proposal—so you can see exactly what you're getting. Our services involve slope design, correct flashing installation, and code-compliant layering, so you don't have to deal with expensive repairs a few years later.
