Metal roofing
Delta Metals says metal roofs are resistant to wind, hail, snow and fire, and that metal is a non-combustible material.
Wildfire code
Delta says its perforated flush mount soffit meets the 2026 Colorado Wildfire Resiliency Code in most locations. Check with your local building inspector.
Under deck drainage
Trex says RainEscape keeps rain, spills and snow melt from dripping through the deck boards, so the space below stays dry.
