Mark and his colleague were really nice and polite. The roof on my porch started leaking one weekend and Mark was out within 24 hours to have look at it for me. Work had to start a few days later than planned due to poor weather conditions, but Mark kept me informed at all times. The work was professional, and tidy. On the second roof it be came apparent the flashing also needed replacing, and I was informed immediately. I would not hesitate to use again or recommend. (Reviewed January 2016)
