WASECA HOME OWNERS GO GREEN
THE BERGS GO GREEN
When local Waseca residents Perry and Renata Berg’s roof started to leak, they decided to take a green approach. They called their local contractor, Greener World Solutions for advice. As it turns out, the Berg’s roof was a perfect candidate for a spray foam roof system, also called a “cool roof”.
ADVANTAGES OF A COOL ROOF
A cool roof system offered the Bergs many advantages. First, it eliminated all the joints and seams on their roof. Joints and seams are typically the number one
cause of roof leaks in traditional roofing systems. Secondly, for the Berg’s, the cool roof eliminated the need for roof rock. This greatly lessened the roof load. Best of all, when comparing a cool roof to a traditional roofing system with comparable insulation, the cool roof was more cost effective.
The most important part of a roofing system is to keep water out. One of the great features of spray foam is that it can be sculpted to fit unique situations. With the Berg’s new cool roof system, the edges of the roof were tapered upward to divert water toward the scupper and into the gutters.
WHAT MAKES A COOL ROOF “GREEN”?
Many old roofs were not properly insulated when they were first built. Spray foam insulation, the main component of a cool roof, adds R-value. On the Bergs roof Greener World Solutions was able to add almost 11-R to their roof. This means the Bergs will burn less fuel to heat their home.
Another important component of a cool roof system is the reflective coating. In the summer, the reflective coating will keep the Berg’s roof 20˚F cooler than a traditional roof system. The Berg’s will use less electricity to cool their home.
In years to come, the Bergs will have little roof maintenence. As the roof ages, it can be recoated to extend its life indefinately. This eliminates the need for future tear-off waste and re-roof projects.
