If you're thinking about metal roofing for your Mililani home, here's the math: metal costs more upfront ($12-$22 per square foot versus $4-$8 for shingles), but metal lasts 2-3 times longer, cuts cooling costs 15-25%, and has virtually no maintenance. Over a 50-year span, metal is the cheaper option.
We install 24-gauge and 26-gauge steel panels in Galvalume and pre-painted finishes. Kynar 500 PVDF fluoropolymer coating is the gold standard. It resists fading, chalking, and color shift for 40+ years. Sheffield Metals and McElroy Metal are our primary suppliers, both with proven track records.

Custom Panel Fabrication
Panels ordered in your selected color, gauge, and profile. Custom lengths cut to minimize waste and on-site seaming. Trim pieces, flashing components, and underlayment specified for your roof.
