Coryell crew worked nights to avoid disrupting classes . . . The Coryell crew took on the challenging job of installing a new roof at night to avoid disrupting classes at Wanette Public Schools. The flat roofs on Wanette’s buildings had severe hail damage to the previously applied, smooth, built-up roofing system. The system that had not held up well in Oklahoma storms. Coryell came in and installed a white, 50 mil Durolast roof system–a system that will hold up in Oklahoma storms! In addition, the crew installed code-compliance insulation values, which added energy savings. Another job completed with the customer’s best interests served in every way!
