"We just had a roof done by home genius exteriors. We started with Justine at our door setting up an appointment for someone to tell us about the process. The next day Dan came and explained how the company works. He even crawled around our attic to show us the damage. Within 2 days our roof was in the process of being installed. Zach the project manager stopped by 3 times during that day to see how the work was being done. What a professional company. Everyone that we spoke to or met was very professional and friendly,. I would highly recommend this company for installing a roof."

"This company was extremely reliable and worked very fast to get the job done. We used them to renovate an apartment for rent and they were honest with their prices and even suggested options to save us money. We would definitely utilize them in the future and recommend them. I wish I had taken before and after pictures to show what a great job they did. Also, we were really impressed that the contractor sent us pictures and contacted us every time they completed anything."

Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions.
