Built-Up Roofing

Multiple layers of reinforced scrim or felt between moppings of asphalt or coal tar pitch has been a staple in Chicago roofing for well over 100 years. Top coatings of gravel embedded in asphalt or coal tar, asphalt top coat and aluminum coating offer different reflectivity for different situations.

Modified Bitumen Membranes

This material consists of fiberglass, polyester or a combination of both polyester and fiberglass scrim sheets laid between or set on top of molten modified asphalt and then cooled to form a pliable roof system in rolled form. The (2) types of modified bitumen products offered are APP (actactic polypropelene) and SBS (styrene butyl styrene).

These are tough roofing products that are excellent in dealing with the weather extremes in the Chicago area and can handle foot traffic better than most other roof systems. Combine either product with built-up roofing plies and we can offer warranties up to 25 years.

Many surfacings are available for these products such as asphalt emulsion, aluminum coat, granulated surfacing in different colors, asphalt and gravel and acrylic coatings. This roof system is one of the most popular roofs being installed in Chicago.

Frequently Asked Questions

What is the most suitable material for flat roofs?

At Allendorfer Roofing, we recommend EPDM membranes as the top choice for flat roofing due to their affordability, simple installation, remarkable durability, long lifespan, and stylish finish. These factors make EPDM an excellent option for flat roofing solutions offered by Allendorfer Roofing.

What are the benefits of having a flat roof?

One of the main advantages of flat roofs is their lower costs for both construction and repair. Flat roofs require less material, making them more cost-efficient during the initial construction process, but also saving money if any repairs become necessary in the future.
