Project Scope:

  • Completed two roof replacements at two buildings: 20 & 21 Custom House Street.
  • Full removal of the existing room systems and all associated flashing systems, which were built in 1988 and still had their original EPDM and in some cases, ballast roof systems.
  • A Sika Sarnafil PVC roof system was chosen for both buildings.
  • Performed a roof seam probing and Electronic Field Vector Mapping (EFVM) as part of the final punch-list to ensure a water tight roof system that will help make the buildings more energy efficient and last for years to come.
