We recently had our flat roof replaced by Citywide Roofing and have been very pleased with the work. Dan and his team were friendly, hardworking and a pleasure to have around. The work was completed to a high standard and the site was left clean and tidy. After the work was completed, we asked if the gutter flow could be adjusted slightly. Dan came back promptly in a good-natured, helpful way. To me, that speaks volumes about the confidence he has in his work and his willingness to stand behind it.
