Frequently Asked Questions
Is Vangard 42 IR a Class 4 hail-resistant shingle?
Yes. Vangard 42 IR meets UL 2218 Class 4, the highest impact category, thanks to its SBS (rubberized) modified asphalt. In hail-prone Calgary it’s BP’s best choice for impact protection and may qualify for an insurance discount — check with your provider.
What does the high-wind warranty cover?
Vangard 42 IR carries a standard wind warranty to 110 mph (180 km/h) and a high-wind warranty up to 135 mph (220 km/h) when installed to BP’s requirements.
Why does SBS-modified asphalt matter in Calgary?
SBS is a rubber-like polymer blended into the asphalt that keeps the shingle flexible in cold weather and helps it absorb impact — valuable through Calgary’s freeze-thaw winters and hail season.
What colours does Vangard 42 IR come in?
BP offers Vangard 42 IR in several colours for the Canadian market. Iron Shield Roofing confirms the current Alberta lineup with our suppliers for each project.
