Recent Review: I researched the different types of flat roof applications including bitumen, built up roofs which are the most common. The existing roof is a built-up. I was intrigued by a fairly new process, urethane foam application. I requested bids from six roofers. Only two could provide urethane foam installation in Tucson. Urethane foam can be applied to a new roof, existing roof tear off, or as an overlayment to any existing flat roof. The insulation "R" value is higher than a built-up roof and there is never any chance of leaks as the product is sprayed on with no gaps or seams. Big plus! Pricing. No consistency from one bid to the next. Each roofer wanted to do something different. From a complete roof tear from one to only patching leaks from another. So comparing pricing was not easy. I settled on overlayment of the existing roof and replacement of the patio roof and asked the bidders to revise the pricing accordingly. Only 4 of the 6 responded. One would not provide overlayment, only a complete tear off, but could never specifically tell me why a complete tear off was necessary. Only that older roofs should be torn off. Needless to say I was not impressed. Sales Process. One roofer stood out among them all, Lyons Roofing. The sales reps from Lyons Roofing took extra time to explain the different types of roofing systems, were the most professional in their approach, brought samples of the product and provided a thorough explanation of why urethane foam was a dramatic improvement over bitumen, or rolled roofs. The pricing was also in line with the other bidders, albeit slightly higher. I chose Lyons. Installation. I was assigned a project manager who called a week before the install and scheduled time to review my order and visually inspect the roof. He took copious notes and made additional suggestions (skylight options). The crew showed up when promised and were professional and courteous. They were careful to lay down drop cloths to catch debris and cleaned up after they left. The project manager checked in with me each day and performed a final inspection with me when complete. Top notch. The urethane roof was the right choice. Lyons knows how to run a business, not just install roofs. IMPORTANT - Lyons does not subcontract the roof tear off like other companies who pay temp employees by the job. Take the risk if you will, but that didn't sit right with me and was glad Lyons did all the work themselves.
