I had a leak on the roof that was coming through my bedroom ceiling, so I called Zimmerman's Roofing to come and check it out. The technician took the time to check thoroughly to find the exact source of the leak. I could not believe how much he did taking the time to go up into our attic to check behind walls that we have never even been up in. He even checked behind some panels. It was only when he felt that he had found the precise problem then he went to work on it. The technician fixed the roof in like one hour or less. I was amazed at how quickly he finished the task. It has rained since and everything has been just fine. I would highly recommend Zimmerman's Roofing. Not only was the technician knowledgeable and professional, but he was a really super nice guy too. He had such a great personality. I would definitely give them a call again if I needed them.
