“I was really impressed with this service. Oleg came to inspect my roof the day I called him and gave a very competitive quote. He remained in touch while we waited for good weather, then his crew arrived at eight the first sunny day and were done by four. Clean quiet job, all cleared away the same day, and my patio left tidier than they found it!”
