Durapax Offers Proven Long-Lasting Coal Tar Commercial Roofing Systems

Providing roofing contractors and specifiers with a new option for reliable, long-lasting low life-cycle roofing systems for flat and low-slope commercial roofs, Durapax offers complete coal tar roofing systems. The coal tar roofing systems are designed to stand up to harsh rooftop conditions such as hail, rooftop traffic, exposure to ponded water and are said to be resistant to common industrial chemicals, oils, animal fats and extreme temperatures. Coal tar’s unique cold flow properties allow it to “seal-heal” minor cracks and punctures on warm days – before leaks can develop.

Founded in 2004, Durapax specializes in coal tar built-up roofing systems and materials, including, coal tar pitch, coal tar saturated organic felts, coal tar coated glass fibre felts, coal tar maintenance products, as well as organic and glass fibre base sheets. Durapax acquired its coal tar technology from a leading materials manufacturer. Durapax’s coal tar roofing systems carry comprehensive warranties and are manufactured to meet ASTM specifications as well as UL, Class A and Factory Mutual Engineering certifications. Durapax markets its roofing materials through a nationwide network of distributors.

Coal tar has been used as a premier roofing material for over 150 years. Expert roofing contractors and specifiers choose coal tar roofing systems because of its low life-cycle costs, superior resistance to ponded water and extreme temperatures and long life span, averaging over 25 years. With proper maintenance, coal tar roofs have been known to last more than 50 years and can usually be extended another 10 years or more with a restoration flood coat.

According to the company, coal tar is the ideal roofing material for “green roof” systems, evaporative water-cooled roofing systems and retarded drainage roofs because of its resistance to ponded water. These coal tar roofing applications save energy costs, reduce the burden on sewer systems and decrease urban “heat island” effects. Aggregate surfaced coal tar roofing has a typical reflectivity of 0.34 – twice the reflectivity of forests and meadows. And, because coal tar roofing systems last longer, they reduce landfill volume.
