Some of the flat roof types we offer in Illinois, Wisconsin, and the surrounding areas include:

TPO roofing, or Thermoplastic Olefin, is a single-ply membrane made from a blend of ethylene propylene rubber. This material combines the strength and durability of EPDM rubber with the superior performance of hot-air weldable seams. TPO roofs are highly resistant to ozone and algae, making them an environmentally friendly choice that is completely safe for installation. Designed to withstand the harsh weather conditions we experience in Illinois and Wisconsin, TPO roofs have consistently met and exceeded the expectations of our customers.

Coal tar, also known as hot tar, is highly resistant to temperature fluctuations, vapor transmission, moisture, UV rays, chemicals, and water droplets. This self-healing material features a low melting point, making it durable and effective under a variety of conditions. However, it is not recommended for roofs with slopes steeper than 1/2" per 12". For over a century, coal tar roofing has been a standard choice in the low-slope commercial roofing industry, offering long-lasting performance and reliability.

EPDM, or Ethylene Propylene Diene Monomer, may sound complicated, but it's actually a straightforward and highly effective roofing material. One of the key benefits of EPDM roofs is that they consist of a single layer of material, unlike other systems that require multiple plies laminated together. EPDM can be fully cured before installation, or it can naturally cure over time through exposure to the elements.
