The Walpole Town Hall in Walpole, Mass., had a 53-year-old slate roof that was beginning to progressively deteriorate. Slate tiles had started to chip and break at an alarming rate, allowing whole tiles to shift and fall off the building.
Leaks were becoming common, and the falling tiles were creating a serious safety hazard. Due to the success of a new metal roof on one of the schools in the historic town, the town opted to replace the town hall roof with a metal one.
The slate roof was stripped down to the concrete decking and replaced with a high-performance waterproofing membrane followed by 23,000 square feet (2,137 m2) of The Garland Co. Inc.’s 22-gauge Galfan-coated R-Mer Span 18-inch (457-mm) structural standing- seam roof system. The soffits and facias were rebuilt to support the 0.050-aluminum gutters with a Kynar fluorocarbon paint finish by Arkema Inc. to match the roof system.
