We called Osvath because we noticed their signs at plenty of jobs around the neighbourhood. It tuns out that they are based a few blocks from us and we like to hire locally.
They quoted our roof in March of 2011. Both Andy Osvath and his son Jake came and surveyed the job and the work was done at Easter of 2011. They showed up when they said they would and were on the job for the three days they predicted (not counting rain delays - they can't control that...). They left the site clean and tidy at the end of each day.
The aluminum work was done in two short days. It is also complete, tidy and has, to my eye, spruced up the look of the house.
I was impressed with their work and, importantly, their attention to safety. They were harnessed and roped while on our roof. Attention to safety shows a level of professionalism that is reflected in the finished product. This is something that I have noticed some contractors ignore and have seen roofers prancing around without safety lines.
The work has been in place for seven months now and there is no problem at all. The whole thing was stress-free for us. They weren't the cheapest, but they weren't the most expensive. The price was fair and we got a good job.
