In May 2011 on Maplewood Ave. in Chicago near the Wrigleyville neighborhood, we replaced the existing roof on a 2-flat residence. This roof had 5 layers, well over the legal allowed limit of 2 layers. When the roof was torn off the ceiling was insulated with r30 of blown in Fiberglass insulation. The new roof that was installed was a fully adhered 60 mil TPO roof system with a 20-year system rating. We installed a new commercial oversized box style gutter and installed a custom oversized roof hatch with pull down stair case. As part of the project one chimney was rebuilt and the entire parapet walls were also rebuilt on this century old home.
