Zimmerman's Roofing did a good job installing vinyl siding and stonework. However, we scheduled them to start in September. And they didn't start until January. I expected them to be here within a month or even six weeks. I'd call and ask when they were going to start. They got busy with another project or they said the weather wasn't permitting them to start. But I will give them credit because when they did finally come out, it was 30 degrees and snowing. There was only one problem when they put up the vinyl siding. They damaged the kerosene coil going to the furnace. They damaged the nut and air was getting in. Although, they split the furnace bill with me which was incredibly nice. Plus they were very professional, friendly and knowledgeable. I would continue to use Zimmerman's Roofing's services for more stonework.
