Zim Group

Zim group recently installed a new metal roof for our home. Right now
I have only positive experience. As I work in research, I started to
explore roof technologies and roof technology best suited for us I
found is modern metal roofs. If somebody is interesting in roof
energy efficiency, you could read
http://web.ornl.gov/sci/buildings/2012/B11%20papers/64_Miller.pdf for
example.

After choosing metal roof technology, I started to investigate modern
metal roof options. We looked mostly for stone coated roofs until we
found Zim group.

We chosen Zim group for a product they install: non stone-coated but
better metal roof technology of sweden company Areco
http://www.areco.se/en/villaroof_stratos.html. And still the quote
was 3-5K smaller than other 4 quotes for other stone and non-stone
coated metal roofs installed by other steel roofers in our area.

But even better technology needs the right installation. It is very
important. Fortunately, we got a very experienced team to install the
roof. The team leader installed such roofs for more decade. He has a
good job attitude. He told us that a power cable to neighbor house
was too close to our roof and the problem was solved by Toronto Hydro
the same day. All promised was done. The team worked hard for almost
4 days and cleaned up everything after their job. Communication with
Zim group representatives was quite good which was not true for some
other companies. They responded my calls the same day and gave me
good answers for all my questions and concerns. The job was done on
schedule (it was important for us as we were going to install new
eavestroughs by another company after that). Another good thing about
Zim group they started all job on a short notice after signing the
contract, exactly when we wanted.

So after installing Zim group metal roof, I feel that home became
cooler this summer we did not use air conditioner for 4 weeks after
the roof installation. The attic is much cooler (before it was a
sauna, now its atmosphere is close to room one).

Although the roof is not cheap (it is 2.6 times more expensive than
a quote we got for shingle roof from another company), I hope it will be
cheaper in long run because of its longer lifetime and energy savings
besides it has many other important advantages.
