I have been nominated to build a decorative, concave, metal-covered, wood-framed awning over front door for curb appeal. I have spent 2 weeks on-line looking for information, pictures, blueprints. Covering to be 72" wide, 27" deep, 30' tall. These measurements based on specs for custom-made copper covered awnings (@ $ 1200-1600.00 ). I figure there needs to be ribs (cut on band-saw of cedar, curved) attached to frame, covered in 1/4" (how do you spell luan

), then covered in freeze-proof membrane, then covered in aluminum (which is readily available in myriad of colors). You see these all over in the UK, but none in USA. Realize leak potential at attachment site, so think I should leave 12' or so of membrane above awning to attach to underlay of house which will THEN be sided ! As I am not a "builder", does this sound feasible ? Has ANYONE seen blue-prints for this type of "roof" ? We do not want a huge thing supported by columns. I will attach the awning to 2x4 frame which will be pre-hung, and supported by decorative cast iron brackets. Alas, this must be installed in 3 weeks!
