SBS Shingles in Calgary

Technology has infiltrated every aspect of our lives – including our roofs. New processes and new materials are adding strength, longevity, and increased aesthetics to homes across North America.


Although most standard or entry-level roofing shingles are still made with blown asphalt, roofing manufacturers are increasingly using polymer modified asphalt (PMA), or styrene-butadiene-styrene (SBS) for their upgrade and premium shingles. Their increasing popularity recently earned them an article in Asphalt Magazine.


At Century Roofing Limited we’ve been installing strong, durable residential and commercial roofs for 35 years, including premium products like Malarkey Roofing Products’ SBS Legacy® Shingle Line.


The Legacy’s stunning appearance complements the excellent product performance of SBS “rubber” modified asphalt shingles. For over 25 years, Malarkey has been leading innovation with SBS “rubber” modified asphalt to vastly improve shingle product performance. Malarkey was one of the first manufacturers to recognize the advantages of the SBS modified technology and developed the first SBS “rubber” modified asphalt shingle.


“SBS makes a dramatically superior shingle,” says Greg Malarkey of Malarkey Roofing Products. “We’ve been using SBS in our roofing shingles since 1986. We use it in combination with virgin asphalt to produce our premier shingle – the Legacy line.”


Better weathering and impact-resistance are the two primary benefits of using SBS in asphalt roofing shingles. SBS polymer modified shingles are also useful for hip and ridge work because of their flexibility. If the SBS shingle cracks and it’s flexible, it can heal itself. Adding polymer to the shingle also increases its resistance to cold weather and thermal shock. Impact-resistance is another key element of the importance of making a shingle line that can withstand high winds and hail storms.


Malarkey says SBS shingles are definitely stronger and weather better. “They need to have enough polymer in them,” Malarkey says. “Most asphalt shingles are modified with 6 to 7 percent SBS, but more is needed.”


Although SBS has been used in commercial roofing for many years, its use in residential shingles is relatively new. But, there is no doubt that its use in shingles will expand the premier shingle lines throughout the industry.


“SBS is opening up the range in markets,” says Malarkey. “In the future we’ll be able to make shingles for Arizona, as well as Alaska. We’ll engineer asphalt shingles for the geographical area and the specific conditions.”
