Pataskala officials say the city will need to replace the slate roof on the building at 430 S. Main St. that is home to both the Pataskala Division of Police and the Sterling Theater.
"We're looking for longevity," said Mike Compton, a member of Pataskala City Council and chairman of the building and grounds committee.
Built in 1916, the two-story brick building initially was used as municipal building and frequently is referred to as the Old Town Hall.
"There are a lot slates missing and it's leaking through at various locations," said Robert Schroeder, Pataskala's project manager.
"It's been up there almost 100 years and it's beyond its useful life."
The city paid Mays Consulting and Evaluation of Delaware $4,395 to inspect the roof.
The firm provided the city with recommendations and cost estimates for replacing the old slate with new slate or metal.
Compton said replacing the roof with metal could cost an estimated $104,000. Replacing it with slate could cost an estimated $125,000.
He said both metal and slate have a longer life expectancy than shingles.
"We're leaning toward slate," Compton said
The building and grounds committee met May 6 and discussed maintenance of the two materials.
Compton said he also is concerned about how metal could affect the theater, which is on the second floor.
He said he has a metal roof on his house and on the front porch and it's impossible to hear anything on the porch during a rainstorm.
Compton said the roof also might require other repairs, including the soffit and roof overhang, which could add another $15,000 to $20,000 to the cost.
Pataskala Finance Director James Nicholson said the city has not set aside any funds for the project.
