Malarkey Northwest-xl - Asphalt Shingles - A1 Roofing Calgary

One of the most critical aspects of a successful roofing project in Calgary is correct shingle installation. Improper fastener placement is the leading cause of incorrect shingle installation and can subsequently void the warranty. The Northwest-XL™ is manufactured using the patented ZONE® technology which includes a tapered nailing area over three times larger than other laminate shingles. The ZONE’s® larger nailing area dramatically improves correct fastener placement.
