Out of several quotes, Kirill's was the best, plus he was able to show all required papers (licence, insurance, etc). He explained everything in details, put everything in writing, so my neighbor and I were satisfied (we live in semis and re-roofed the whole roof for both houses).
They started on time and it took them two days instead of one, as promised, to finish the roof, which was a minor inconvenience. But job was well done, I went on the roof myself to check everything. They worked real hard both days and cleaned very well after finishing the roof. I'd definitely recommend them!
