Metal roofing has moved well past the corrugated barn look. Today's standing seam panels come in 40+ colors with Kynar PVDF finishes that hold their color for decades. Our Portola Valley metal crew installs standing seam, corrugated, and metal shingle profiles for homes and businesses.
Standing seam is the premium metal roofing system. Concealed fastener clips allow the panels to expand and contract with temperature changes without stressing the seams or the deck. No exposed screws, no exposed fastener holes, no maintenance. The seams interlock and the clips float. That's why standing seam doesn't leak.
Our Metal Roofing Process
Metal Roofing Consultation
Our estimator visits your property, measures the roof, and walks you through material options. You'll see color samples against your home's exterior. Budget comparison between standing seam and exposed fastener options provided.
Material Preparation
Metal roof panels are custom-ordered to the exact lengths needed for your roof. Trim, flashing, and ridge cap pieces specified and fabricated for your specific roof geometry. Lead time is typically 2-3 weeks for custom orders.
