The Challenge: The existing building in downtown Boston had restricted access. A Garlock Hoist had to be used to stock the job and remove debris, as it was the only practical way to access the roof. A large reinforced concrete "apron" that was in place around the entire perimeter of the main level had to be cut up and removed prior to the start of re-roofing work. Other considerations were the building's location in a coastal wind zone, positive pressure inside the building, and a tight schedule dictating that the project be undertaken during the winter.  

Project Scope:

  • Test cuts and a survey of the existing roof system to determine its condition and construction.

  • Based on testing and survey results, it was recommended that all existing roof systems be completely removed and replaced in all three roof locations.

  • Replaced penthouse and main levels with a new insulated Sarnafil PVC system.

  • Cooling tower roof replaced with new insulated fluid applied Sika system.

  • All roof edge metal and flashings were replaced, and steel columns supporting a series of louvers were removed, rehabilitated and reinstalled.

  • A new, energy efficient, integrated roof system with a projected 20 year minimum lifespan was completed.
