Replacement of the Richardson Public Library roof began Jan. 14 at 900 Civic Center Drive, Richardson. Construction is expected to last between three and three-and-a-half weeks, according to the city. A portion of the south parking lot will be blocked off, and guests on the third floor may experience noise while repairs are ongoing. The new roof will be painted with a solar-reflective white coating, making it more energy-efficient, according to a city spokesperson. 972-755-4350.
