BLOOM TOWNSHIP | Some temporary patch work is being planned for part of the roof at Sandridge Elementary School.

One of the issues is the blistering occurring over the building's latest, 2005 addition and whether water has made its way into the roof sub layers.

"We feel we have a plan now to address the concerns," said John Sawyer III, District 172 superintendent.

Sandridge is the only school the district board manages.

According to Sawyer, the roof still is under warranty and the patching by Jay Adler Roofing and the April study by Tremco Co. is not expected to cost the district anything.

Also, there is no physical evidence of any moisture but if there is, re-roofing may be necessary, he said. Meanwhile, district and school officials met with the district's architect and roofing company representatives last week to discuss roof concerns. Officials estimate there are about 30 or 40 blisters across the entire surface of the 2005 building addition.

As soon as weather permits, Jay Adler Roofing workers plan to do the temporary patch work. Patching will be done on an area near the gym and where two hallways intersect where a couple of the blisters have broken open, according to Jack McCleverty, director of buildings and grounds.

School Board Vice President Donald Witvoet, chairman of the board's building and grounds committee, said the blisters are not confined to a single area of the 2005 building addition.

When warmer temperatures arrive, workers from Tremco Inc. plan to use an infrared detector to determine whether there is any moisture trapped between the roof layers.

At this point, Witvoet said the roof issues are small, but officials are concerned about them because they continue to happen and they eventually could lead to bigger problems.
