CertainTeed's NorthGate SBS modified asphalt shingle is unmatched by standard asphalt shingles. The rubberizing aspect of SBS allows greater flexibility so the shingles resist cracking even in extreme cold-weather, allowing for year round application. SBS also offers superior granule adhesion which is one of the key components in protecting the shingle against the elements.
