Additional scope includes removal and replacement of damaged EPDM and shingle roofing systems down to original decking, installation of TPO roofing systems with polyisocyanurate insulation and required flashings, exterior pressure washing, surface preparation, caulking, and painting of all existing exterior surfaces excluding roof panels. Competitive sealed proposals from qualified subcontractors are due Thursday, June 18, 2026, at 2:00 PM at City of Douglas City Hall, 302 S. Madison Ave., Douglas, Georgia.

All removed materials must be disposed of off-site, and work must comply with OSHA fall protection standards and manufacturer specifications for all roofing systems.
