I got 3 quotes to replace our shingles, not an easy flat roof but one with large dormers front and back. All Tech was working in the neighbourhood and Victor came by to measure. He provided a quote within 2 days, and dropped off shingle samples. His quote was thorough and by far the lowest, by more than half, for the same shingle quality. The work was done within 2 weeks and above all the property was draped and kept very tidy throughout. I was very impressed with his professionalism and the work itself. It is gratifying to see that not every contractor in affluent areas overcharges for their services.
