Lite weight roof materials for Patio Covers and Pergolas allow for reduced footing and beam size, which saves big money! Standing Seam metal roofing panels are attractive as viewed from below or from your 2nd story window.
It looks like an open lattice roof but you can enjoy the rain and plenty of light. Your guests may not even notice that you have any sort of waterproof roof covering. Remember that it is visible from a 2nd story window. Yours or your neighbor's.
