wow, these guys are working on a roof at the corner of Merivale and huntclub right now and one of the workers just purposly threw an open garbage bag out of their car, spilling litter all over the parking lot and drove away. What trash. If you care about your community/environment/ others, don't hire these guys

very professional, excellent service and competent staff

I live in a group of freehold condominiums, each with an upper and a lower flat roof. Because they're freeholds, the board has no authority to impose roof repairs and because 8 houses share one flat roof, the challenge for all the years I've lived here (13) has been to find a way to allow one homeowner to replace their roof without damaging the roofs of the neighbours. When my roof started to leak in the late spring, I had no idea what I was going to do. Fortunately, I found CLS Roofing which is certified to install a sealing product which has a 10-year manufacturer's warranty. It was the perfect solution as the installation did not interfere with the existing membrane which I share with 7 other homes. Chris and Brandon were very anxious for me to understand what I was getting. When I emailed them questions, they answered very promptly. They even took to another customer's house to see the coating for myself. They did the work in just two days. I only encountered their team members for a few minutes but they were very professional. I recommend CLS for a roofing solution that had eluded my neighbours and me for more than a decade.

10hr weeks 3 weeks in a row. No layoff. with kids, families, mortgages. 4 families on just my crew. This is how CLS treats its team. Happy holidays.

In March 2015 our Condominium Corporation hired CLS Roofing to replace four flat top building roofs on our property. This was a challenging contract due to the very poor condition of the roofs that were being replaced. In all phases of this job we found CLS Roofing to be professional, competent and well-experienced. Their crew members worked extremely hard and kept the job site clean and safe. We have not had one issue with our roofs since their replacement six months ago. Not only would we recommend CLS to others, we have since hired them back to complete another job on our property!
