Murrell Roofing Co. in Independence worked on my flat roof on my back porch. I live in Parsons KS. . A couple of month after it was installed, they called and asked if we had any problems with it leaking. It has not leaked and we are very satisfied with the work they did. The actual cost was less than what they had bid. If in the future I need my whole roof replace they will be the 1st I will call
