WILTON — Voters at a special town meeting Tuesday night approved spending $4,819 to repair the town office’s roof, which started leaking after Tropical Storm Irene hit the area on Aug. 27.

Blodgett Builders, a Wilton contractor, will begin the project in early December and take a couple of days to finish, Town Manager Rhonda Irish said. The contractor submitted the lowest of four bids to do the work, with $6,000 as the highest bid.

High wind and heavy rain from the storm damaged the 39-year-old roof, and the repair will install new shingles and other water-resistant features. Selectmen plan to pay for the project from the town’s undesignated fund.

The undesignated fund consists of unspent tax dollars from previous fiscal years and a public vote is required to spend from it, Selectman Terry Brann said.

Professional auditors recommend that the undesignated fund contain enough money to support town government services for three months in case of an emergency. After the roof repair project, there is still about $1 million in the fund that meets the criteria, according to Brann, who is chairman of the board.
