NRCA Metal Shingle case studies
NRCA Metal Shingle · Put your knowledge to work in context.
The NRCA Metal Shingle credential is a professional certification for roofing contractors, installers, and supervisors who work with metal shingle systems on steep-slope roofs. It signals that a candidate understands how metal shingles differ from asphalt or tile: panels and individual shingles move with temperature, they rely on concealed fasteners and interlocking seams, and they demand careful layout so courses stay parallel and exposure stays uniform.
