Jason and Justin had done the flat part of our roof in 2015 when we put on an extension and we were very happy with that experience. At the time, Justin mentioned that we didn't need to worry about the peaked roof just yet, as it likely had anther 5 or so years left on it.. Wouldn't you know it, 5 years go by and the shingles started curling, so i called up the guys. It was late June, and I'd been working from home since March - the darkness in our stairwell, even during the sunniest days of the summer, was really starting to bother me. So i reached out to Justin to ask if they had any availability to come in to replace the peaked roof and install a Velux skylight (as i knew that they'd done so for a neighbour of mine) - they had the time and the price was just about perfect. Once we cemented the details, we were a go. The process was fast and although they were literally cutting a hole in my roof/ceiling, i was never concerned about mess or damage to the structure. The end result is glorious. Every morning, i open up the remotely controlled blind and light just floods the stairwell and second floor. And yes, the roof looks awesome too!
During the clean-up, one of the front steps of our porch was damaged. Oh no! Called them up - Justin and Jason came by a week later and fixed it up as good as new.
