Fantastic service, clear & consistent communication, and a beautiful, durable product. Simply one of the best contractors we have ever worked with. We got quotes from numerous leading roofers for this job. Mike from Interlock was the only one who came to our house, spent an evening patiently explaining every aspect of the job, showed us many photos and described some of the technical aspects in ways that were easy to understand. When we called back with more questions, he was always available and always super helpful. For the installation, Mike recognized that we had an old house and were concerned about the workmanship. He sent us an experienced crew led by Oswaldo that went above and beyond any expectation we could have had. They not only protected our home but also took pains to protect the neighbours' homes beside ours. They gave us near daily briefings and showed us photos of everything they found on our roof and their work throughout. The job ended up taking much longer than anticipated because our roof had many problems that needed to be repaired. Oswaldo and Mike worked with us to make sure everything was taken care of and repaired before the new roofing was put on. They proved flexible and extremely diligent, communicating effectively throughout. We are thrilled with the result and grateful for all their hard work. We would not hesitate to use their services again and highly recommend them to anyone looking for roofers. As a bonus, we're delighted that we will never send another huge pile of asphalt shingles to the landfill again!
