Leska LLC have installed curved copper roof panels on this pool gazebo roof in Potomac MD. Each concave Panel was custom made by us to contour the steep radius curve. 1" tall standing seam copper roof was installed. The real craftsmanship is required on such installation. The panels are not cut and soldered like others will do but actually curved and full standing seam lock is true out the roof. This gazebo also have European gutters and snow guards.
