Dave and the installation team were great and very thorough. Great product and for about 30% more cost than a typical shingle roof and lifetime warranty makes it excellent value as well.

We are very happy with our new roof. Green Metal Roofing crew were on time, energetic and worked hard each day. They are extremely polite, professional and respectful of the property. Shout out to Dan who worked harder than any young man I know. We look forward to seeing you folks back here in a hundred years or so when it’s time for a touch up or a replacement roof. In all seriousness, it was the best contractor experience we have ever had.

We recently had Green Metal Roofing install a new roof on our house and we could not be happier with the finished product. From the initial consultation with Greg to the installation crew of Isaac and Oscar, everyone was professional, communicative and friendly throughout the whole process. The crew made sure everything was cleaned up at the end of the day and went over and above with our installation. We highly recommend Green Metal Roofing if you are considering a new metal roof.

Green Metal did our steel roof recently. We are very happy with the work. We love our new metal roof! John Olczak from Green Metal Roofing was very professional. He followed a disciplned process from checking the roof and attic before the project to re-exam the new roof upon completion. He made sure our requirements were well understood and documented, from material to roof installation steps. The work led by Junior the installer was perfect in making every step of the project was done carefully with great quality. The result was very good.

Extremely happy with our new steel roof. John was very detailed and passionate expaining everything and about the product and the process. He even went in our attic to ensure everything was ok with the plywood on the roof. Arthur and his installation team were awesome. Would highly recommend Green Metal Roofing.
