Compared to traditional shingled roofs, which are generally constructed with cedar or pine, asphalt shingles are a much more cost effective way to create the desired aesthetic of shingles, without the high price tag.
In New Zealand, one of the leading suppliers of shingled roofing materials is SPS Roofing & Building. They’re seeing a steady incline in the specifications of asphalt shingles, particularly the American-manufactured Owens Corning shingles, which have recently achieved CodeMark certification.
Owens Corning asphalt shingles are created with the same fibreglass material in their core that is used in Pink Batts™ insulation products, giving the shingles a unique thermal property. They are installed on top of a plywood substrate adding structural integrity and stability to the roof. The tiles themselves are finished with a ceramic granule to ensure colour stability and UV protection.
