ISO Roofer suggestions besides Hoolahan and Likar

I have long been a loyal customer of both Hoolahan and Likar roofing companies. But they are so beyond busy right now, and we suddenly need a flat roof (over just one small room) resurfaced ASAP. We can't do a thing to fix our growing mold problem until the little flat roof over our enclosed porch is resurfaced. Anyone have a good experience and can recommend roofers other than the stellar Hoolahan and Likar? Or warnings against others? Any help is so very appreciated. -Becky
