Zim Group

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.
