It took a while to get started as they were busy. When they started they were here constantly until the job was done. Even on days when the temp was well above 90 degrees, on a slate roof, in the blazing sun with no shade. Getting the job done well within the time frame that they had told me it would be once they started. They even came and did tempory repairs first to stop a leak until they could put their full attention on the job. They were not the cheapest estimate but the quality of how they were going to do the repairs was far superior to the others and they actually seem to know what they were talking about with the slate roof. It seems to be difficult to find someone with good knowledge of slate roofs. I am very glad that we went with this company
