Contacted Zim Group for a quote and Sergei from Carlson Construction came. We agreed on pricing and was able to start work within the same week. Took about 3 1/2 days to get the roofing completed and I didn't have any issues at all. Instant bonding with the working crew and during breaks, supplied coffee and cookies.
Before packing up everything, they did a complete sweep for metal debris all around the house.
Highly recommend Zim Group. You will not regret it at all

We had 3 quotes for our roof in all, Alex was by far the most thorough in explaining what would take place, how the roof would be installed and he walked us through his presentation which answered all our questions. We are very satisfied with the new roof and the installers, we expected as much after meeting with Alex and how he came across.

Without hestitation, I HIGHLY recommend Zim Group for your metal roofing needs. We absolutely LOVE our new metal roof! After meeting with Mykola, we felt confident about hiring him because of his profound expertise (he has an engineering background) and many years of experience in the metal roofing industry . Sal Construction was the team that actually installed the roof and the lead installer, Alex, and his team were AMAZING! They were very friendly, courteous and perfectionists about their work. We were utterly amazed with their work ethic and integrity. You will not be disappointed working with this group of professionals!!!!!

I had a few companies come give me quotes but I was impressed by the person who came from Zim Group. He was professional, had a look at the house and gave suggestions that no one else thought of. He was very knowledgeable. He also noticed that we needed a new downspout. All the prices were comparable , Zim was in the middle.

We liked the curb appearance the Zim roof has which also adds to the 3 in. air space between the old and new roof. Zims ventilation system provides air flow under the new steel and over and under the existing roof resulting in a cooler dryer attic. I climbed into the attic when the ridge boards were opened up and confirmed flow from the soffets and fiber filters.
We feel the installation was done professionally with safety and quality workmanship attained. We have sustained high winds and rain since without any noise from the tiles. I cannot comment on any savings heating or A/C as the installation is less then a year old. We paid app. 2 1/2 times the cost of shingling but the Zim roof has increased our home value more.
With a transferable written 50yr warranty on this product, you can take that to the bank.

When Ande found Zim roofing online I thought: "great, a tin roof is going cost a fortune". Then we found it it was going to be less than shingles. One company wanted $12,000 for shingles! My next concern was the noise in a rainstorm. Zim provided customers in our area and the first Zim owner we talked to said it was quieter than shingles. While I was working in Mississauga I made an impromptu visit to Zim's warehouse and they gladly gave me a tour of the facility. That was when I knew Zim was reputable. I was sold. Less expensive, longer lasting and quieter than shingles? The roof lived up to everything Zim promised. Even the contractor was honest. When he discovered that some of our fascia boards were badly rotted he took me up to show me the boards and I gave him the go ahead to replace them. We highly recommend a Zim roof.

The roof looks great and changes the looks of the house for the better. The team at Arsenal Metal were professional quick and clean up after themselves every night. Comparing metal roof to the asphalt shingles the metal roof is so superior for the price. We were very impressed with Mykola Zaloga with the way he display his technical knowledge on the proper way on installing a roof.

They did excellent work. Nice, friendly, and polite people who did a very neat job. The work that was done was exactly what I had expected. I never had to ask them to do anything, they always got to task before I had time to inquire about it. They did a good job.

We have nothing but good things to say about ZIM Group! The man (the owner I believe) who came was very professional knew what he was talking about, he went into great detail about the project. They were timely, from the moment they came to do the estimate to the time they started the work was very quick. The job was done in 2 or 3 days and was alway kept clean at the end of each day. Everything they said they would do they did. It looks amazing, no problems so far, and have had lots of compliments on the work.

They did a very good job. I am thrilled with the roof! I had some quotes from other companies before I met them at a trade show, so I knew all my options. They did such a good follow up after the show that I thought they would be a good choice for me and I have never regretted this decision. They were professional, quick, and I love my roof!

I had Zim Group put up a new metal roof on my house. They where on time efficient and when they where done the work the first day there was a chance of snow, so they wrapped and secured the roof with a tarp to make sure I had no issues. It did snow the next day and I am glad they took the extra precaution so I had no leaks. The job was finished a few days later and I am so happy with the job and how it looks. It totally transformed my house and I love it, great job to the crew (Alex) and Zim group.

I was very happy with how Mykola was able to explain the advantages of a metal roof and why the metal roof from ZIM was better than other metal roofs.
The cost was also very competitive as compared to other roofing companies. The work was started very promptly and was completed within a couple of days. The installation was completed back in August 2013.
My only minor issue was that a small portion of the excess wood and scrap shingles from my old roof were left under the metal roof, so I'm not sure if that will cause any issues with mold build-up or with the overall ventilation.
Overall, I'm happy with the workmanship and the roof looks great.
