MEGA CITY ROOFING INC. REVIEWS

I used Megacity to install a residential roof and I could not be more pleased with the experience. From the beginning with our inspection and the honest appraisal and pricing right through to the professional, cleanly job they were great to work with. We had been having leaks, and other issues that another roofing co had attempted to "repair". Tom identified the issues, outlined exactly how to fix it and we have not had a single issue since. I'm planning to use them again on another property and highly recommend.

This is the first time I have used this company and will use them again for all our roofing needs. They were prompt and professional while being reasonably priced and the workmanship was excellent. Definitely a 5 star company.

We called mega city to check on a leak and possibly a few missing shingles. Tom came within the hour, was very friendly and patched our roof. Great service, I highly recommended using Mega City roofing.

We've had numerous roofers come to our door saying that our roof was in bad shape and needed to be replaced immediately. We wanted a second opinion and Darryl from C.D. Roofing came out with his drone to show us our roof was completely fine and didn't need to be replaced for several years. We really appreciate his honesty and will definately be contacting him when the time comes to replace our roof.

I used CD Roofing to replace the roof on two houses - one in Whitby and one in Ajax. Ryan Tierney the company representative was excellent. Both jobs were completed successfully and on the agreed time and cost. After a recent windstorm, Ryan had one of his service representatives check the roof to insure no damage. Overall an excellent experience.

Excellent and fast service! I had a leak in the roof over my garage and they came by same day to assess and they fixed the problem very quickly. Very knowledgable and professional. Highly recommend! Thank you!

Honestly super impressed with C.D. Roofing. Finding a contractor around Whitby/Durham that actually shows up on time and doesn't try to pull a fast one is rare, but these guys were awesome. Chris and the crew replaced our roof last season and the whole process was so smooth. They gave a clear quote upfront, worked fast, and cleaned up so well you couldn't even tell they’d been here (no stray nails in the driveway, which was my biggest fear lol). Roof survived the winter with zero issues. Definitely recommend them if you need roof work done! - Ron. Reply

GEXR EXTREME EXTERIORS INC. REVIEWS

We called on a Sunday night, Dave Spalla was here by noon on Monday! Dave was very informative, extremely thorough because he checked our entire roof and garage. He let us know what needed done, and the approx remaining life expectancy of our roof. He went above and beyond. We would highly recommend him to anyone needing exterior work done. He also does siding and eavestroughs. We could have not asked for a better experience! 5 stars across the board.

David just finished a siding job at my home, which was admittedly small but highly nuanced, and knocked it out of the park! He was respectful, highly communicative and completed the job on schedule; also, priced fairly. I recommend him for anyone seeking timely, quality work.

Very satisfied with Dave and his crew. We have used Dave twice and he has done numerous roofs in our neighbourhood. professional, fair pricing and quality workmanship. Highly recommend.
