The roofing system features connected shingles in easy-to-carry stacks, a rigid shingle alignment tool to eliminate micro-alignment tasks, and foot boards that simplify installation on steep roofs by attaching to the tool or support chains. Suspension straps, chains, and cables support the guide bar tool for efficient shingle alignment without manual measurements, with powered winches for vertical adjustments. Ridge and peak cap shingles come off a roll for straightforward installation along edges and peaks. This method reduces labor costs, enhances project completion rates, and addresses labor shortages by increasing worker output and profitability. A specialized cart system transports up to 500 lbs. of shingles directly to the roof, streamlining the process and saving time.
