Lancaster Public Library

This historic library building in center city Lancaster had serious moisture problems that had failed to be corrected by several contractors. When we took over the project we began by reviewing the roof edge flashings and gutters to determine the source of their water-damage, which was the biggest problem. By doing a multi-phase roof replacement we designed a solution that used uncured plastic sleeves inserted into the pipes from the top, and a heavy pressurized balloon system pulled through to compress the sleeves against the pipes, all of which was done without changing the historic exterior of the building.

As another part of the multi-phase project we replaced the leaking slate roof with asphalt shingles, selected for their color similarity to the slate. This was important in maintaining the appearance of the building, which is located in the Historic District listed on the National Register of Historic Places, and made it possible to get historic district approvals.
