LACONIA, N.H. (AP) - Concerns about more roof collapses came true Wednesday, with at least five more collapses in the region, including an old mill building in New Hampshire and a lumber company warehouse in Vermont. The old Allen-Rogers mill building went down overnight, said Laconia Fire Chief Ken Ericson. It was being converted as part of a condo complex. Other collapses Wednesday in New Hampshire included a barn in Manchester, a building at a mobile home park in Rochester and a garage in Concord. In Tilton, a Wal-Mart was evacuated and closed when sprinkler heads began pushing down through the ceiling, signaling a roof problem, according to a fire official. Fire Capt. Robert Bousquet said snow on the roof had drifted to 3 to 5 feet deep. In Lewiston, Maine, engineers were assessing damage to a Wal-Mart Distribution Center after a section of the roof collapsed Tuesday evening. The collapse apparently was in an area of the complex that contains refrigeration equipment. In Brattleboro, Vt., a storage building collapsed Wednesday at the Jack Tarmy Lumber Co. The building housed forklifts and lumber. No injuries were reported in any of the latest collapses, which came after heavy rain fell on the snow-covered region, prompting more calls from officials for homeowners and businesses to clear snow from roofs. School officials in Concord were taking no chances. All city schools were closed and the fire department was evaluating all school roofs on Wednesday. Superintendent Chris Rath said she was concerned about how much weight the new storm would bring. And in Alton, students were sent home Wednesday after a section of the Alton Central School the roof bowed. In Maine, about 2,000 homes and businesses lost power Wednesday. Meanwhile, in northern Maine, Caribou received another 1.4 inches of snow, according to the National Weather Service. The city has now received more than 160 inches of snow for the season, making it the second-snowiest winter on record. Copyright 2007 Associated Press. All rights reserved.
