McKinley Roof Specialists - Everything You Should Know About Asphalt Roofing

Commonly used today, asphalt roofing is recognized as one of the oldest and most durable materials. It is utilized in commercial asphalt roofing by flat roof specialists in Chicago, and in asphalt shingle roofing as a multi-layered waterproofing membrane. This offers the long-lasting protection that homeowners and business owners expect from their asphalt roofing system.
An asphalt shingle roof is not made entirely of asphalt. Instead, this roofing system consists of either a fiberglass underlayment or a felt paper base coated with a waterproofing layer of asphalt topped with ceramic granules to complete the roof. Asphalt roofing is produced as either three-tab shingles or architectural shingles. The three-tab shingle variety is designed to appear as three shingles but it is actually a single piece. An asphalt shingle roof is easy to install, economical, and highly popular. Architectural shingles are manufactured using an additional layer of asphalt. This offers a wide dimension and enables the material to look similar to bulkier roofing products, including wood or slate. Both asphalt shingle roof designs have a large selection of color options to suit any preference.

Built-Up Roofing (BUR) Technology
BUR technology has been in use for over a century, making it the oldest roofing technology still commonly used today. The process for this type of flat roofing in Chicago involves melting bricks of hot asphalt and depositing them between a base sheet, a ply sheet, and a cap sheet to create layers. Ply sheets and additional asphalt layers achieve the desired thickness for the new asphalt roofing in Chicago. Cap sheets are a popular component, but there are other options as well, so it depends on the type of project and the flat roofers in Chicago. Some projects may use a layer of gravel instead of the cap sheet, while some asphalt roofing in Chicago is finished with a top layer of gravel spread over the final sheet of asphalt.

Styrene Butadiene Styrene (SBS) System
A polymeric material, SBS modifies asphalt to produce a modified bitumen, a synthetic rubber that gives the SBS sheets a better elongation rating than other asphalt roofing systems. A typical SBS system features two plies of the roofing membrane. The first ply consists of a smooth-surfaced SBS base sheet that is ordinarily installed over insulation or cover boards. And the second ply is a granulated cap sheet that is applied over the smooth surface during the flat roof replacement in Chicago.

Atactic Polypropylene (APP) System
APP systems include modified bitumen and is an asphalt that has been enhanced with atactic polypropylene, a plastic covering over the roofing membrane that offers protection from the sun’s ultraviolet rays and other weather-related events that can reduce the roofing system’s overall durability.
A key difference between APP and SBS is that APP is usually applied using a torch. But, as most APP flat roofing systems in Chicago cannot be directly torched, sheets are usually installed onto a BUR base sheet or thermal barrier. APP flat roofing in Chicago is an excellent solution for adding protection to an existing roof.

Base Sheet System
Building a solid insulation base with the correct R-value on top of a moisture-controlled environment is the first step toward constructing a lasting system for flat roofing in Chicago. Without that solid insulating foundation, you may end up with a prematurely failing roof.
An asphalt roofing system also requires the proper base sheet to achieve peak performance. The design criteria dictate the necessary features of the platform. Whether you are dealing with asphalt roofing that is APP, SBS, BUR, or even a hybrid, our flat roofers in Chicago offer a full line of appropriate membranes to fill the need.
