On this house house we did a tremendous amount of work. On the main house itself we replaced the half round copper gutters. We hung these with hangers spread 12 inches apart. This ensures greater strength in the winter with snow and ice. We repaired the the slate roof on the main house and installed a new copper standing seam roof. In order to do this we had to replace the wood decking under the copper roof. The wood was also finished. The copper roof itself is soldered, not caulked.
