Workers remote old (circa 1938) slate shingles from the Town Hall roof Monday, continuing work that began recently. Special Town Meeting voters last year approved spending $260,000 to replace the roof. When someone asked why less expensive asphalt shingles wouldn’t be used (noting that asphalt shingles also hurt less when they break loose and fall on someone, Tim Gillespie replied that Town Hall is one of the town’s “historical treasures” and that the project would not qualify as historic preservation if asphalt were used. He added that the Westport Historical Society “would hang us up by our heels” if we considered such a change. Some Town Hall entrances are temporarily closed for safety reasons.
