"I knew from the start I wanted a metal roof and that I wanted the Permalock product for its quality and durability, and that it looked like the shingle roof we had. The lifetime guarantee and product sold me. The roofers were great, and every night the place was cleaned up, very efficient company."

"I'm a return customer. They did our replacement windows a few years ago, and they just replaced our asphalt roofing shingles. They did a wonderful job. I was amazed and impressed with how quickly, and how well, they completed the job. I love my new roof."

"Excellent as far as I know so far. Got just in on time for major snowfall with new roof so will see if any leaks come through where we had had trouble before. Manny was pleasant and professional to deal with. I liked how he took pictures to show where the areas of concern were and updated me as the day went on and new work had to be done. His worker worked tirelessly all day long. The cleanup of debris was impeccable."
