Hello, I live in Liberty, Mo Now and just had to leave a wonderful review for Ryan Construction Systems- Kansas City. I replaced 4 plastic dome skylights in my home 2 summers ago, with 4 double pane glass units. The price was great considering 3 of my 4 windows were custom sizes (two of them 52"x52", another 34"x48", and 1 'standard' size). They delivered all 4 skylights to my house and offered to take away the old ones. I had not removed them at that point. The aluminum frames are very strong. I had a tree fall on my house only a few months after installing the skylights. one of them took the fall and held up very well. the rest of the roof and framework caved before the skylight did. Ryan Construction Systems built a replacement for me about a week after the tree fell and the roof repair. When they delivered the new window they took away the old plastic domes I had stored. They recycled them for new materials, or kept them around in case a future customer needs a replacement. I was happy to get rid of them without having to pay! I highly recommend Ryan Construction Systems. Great staff, and friendly. Not much for a show room but when it comes down to it, they manufacture a superior product compared to skylights made by VELUX. VELUX uses plastic snap in pieces to hold the joints together that support the window pane. JC Barry units have seam welded aluminum.
