New city hall hits roof with recycling
Chris Pritchard said some of the improvements will make the building more energy efficient. Pritchard is with Query-Pritchard Construction of Barnwell, the contractor in charge of those renovations.
One improvement is the tiles, which line the roof instead of shingles.
The old tiles were made of clay and not very energy efficient.
The new tiles are made of 94 percent-recycled materials and are almost identical to the original tiles.
The new composite tiles have a class four-hail impact rating, which is the highest in the industry, Pritchard said.
He said hail damage would not be likely with the new tiles.
They also come with a 50-year warranty and are fully sustainable, he said.
This means the tiles, when replaced, would not have to go to the landfill. They can be recycled, again, he said.
The tiles, which typically cost a little more than traditional shingles, cost less than new clay tiles, he said.
"The city wanted to keep with the same look," he said of the new tiles compared to the original ones.
With that in mind, metal roofing was not considered, he said.
The flat portion of the roof has now been re-roofed with TPO, he said.
This new type roofing is white in color and keeps a building 10 degrees cooler, he said.
"I'd be surprised if everyplace doesn't go to them," Pritchard said of the TPO roofing.
He said it is a better product and is more energy efficient.
The city also chose to replace all the windows with new insulated windows, Pritchard said.
The high performance low E-4 insulated glass is "about as good as you can get in that type window," Pritchard said.
The heating and cooling system has been replaced, he said.
The new system is energy efficient with sealed air ducts, he said.
