Bettendorf Public Library patrons will have a new roof over their heads this summer. 

The city is seeking bids for the removal and replacement of the 30-plus-year-old roof that covers the original lower section of the library, which was built in 1976. The 26,400-square-foot surface encompasses the majority of the building's circulation area, east of the main entrance and directly next to the northeasternmost part of the library's parking lot off 18th Street.

Bettendorf Public Works Director Brian Schmidt said the project identified in the city's five-year capital improvement plan is budgeted at $265,000. The work will not interrupt any services at the library. 

Maintenance staff discovered that water seeped into the inner layers of the roof, deteriorating the insulation and rusting the lower steel decking material, Schmidt said. This style of roof, he noted, usually lasts 20-25 years.

"We held off on replacing it just because it held up so well," Schmidt said.

The new insulation should help improve the efficiency of the library's heating during the winter months and cooling in the summer.

The city is soliciting additional bids to simultaneously replace the 13,125-square-foot roof atop the upper L-shaped section of the library and to repaint the 2,812-square-foot blue metal roof on the building's south side. The roof covering the library's second-floor is more than 20 years old, but it remains in fair condition, according to city documents.

"It's a pretty big project," said Schmidt, who expects the rehab to be complete in August. "If we can fit it into our existing budget, we'll look at replacing both of those roofs."

The bidding period ends at 10 a.m. Tuesday and the contract will be awarded at the next City Council meeting on Tuesday, March 20.
