Northern Lehigh School District continues to spend money for upgrades at one of its elementary schools.

By a unanimous measure, the school board on Monday agreed to authorize administration to enter into a contract with Snyder Hoffman and Associates to design, engineer and assist with the bidding of the replacement of the three rooftop sections on the Peters Elementary gym roof, with a cost not to exceed $5,980.In a related matter, the board also agreed to allow administration to go out for bid on the replacement of the three rooftop sections on the school's gym roof.The project is budgeted in the district's 2016-17 general fund budget.Greg Derr, director of support services and transportation, said the three units that sit on the gym roof are 20-plus year old units that are at the end of their life cycle and need to be replaced.In January, the board agreed to enter into a contract with Weatherproofing Technologies to replace four sections of the main roof and the lower gym roof at Peters Elementary.That project is through the Keystone Purchasing Network at a cost of $489,871, and is to be paid from the capital reserve account.Also at that time, the board authorized administration to transfer $490,000 from the general fund to the capital reserve account to cover the cost of the roofing project.Derr previously said there's a third section of roof at Peters Elementary that is from 1991 which is a rubber roof with ballast on it.He said the roof is at the age where the rubber is losing its elasticity, and as it shrinks, it pulls away from the curbing and the seams start to separate.Derr said it was time to look to replace it before it becomes a bigger project.Peters Elementary was constructed in Friedens in 1954.
