I had a great experience working with Charles from Omega. My roof had hail damage, and Charles made my life easier by working through the process with my insurance company. He came out with the insurance adjuster and worked directly with the claims department on all the follow ups. He was very professional and always kept me in the loop with the latest updates. I'm very happy with my new roof and would highly recommend Charles/Omega to others.
Cole Olson has been fantastic!! He’s helped us navigate submitting our insurance claim due to hail damage, and walked us through the entire process with exceptional customer service!
Cole from Omega has been great to work with! He has helped us with the insurance process and working with us to pick out our new siding and roof. Very professional, prompt, and honest.

Which office serves Janesville?
Our Farmington office at 821 3rd St, Farmington, MN 55024, about 45 miles away.
Does hail damage roofs in Janesville?
It can. Hail 1 inch or larger, the size that can crack shingles, has fallen within 10 miles of Janesville 12 times in the years from 2016, most recently in September 2025. After a storm, have the roof checked even if nothing looks wrong from the ground.
Are homes in Janesville due for new windows or siding?
It depends on their age. The typical home in ZIP code 56048 was built in 1973, and 62% were built before 1980. Original windows, siding and roofs on older homes are often worn or drafty, so it pays to have them checked.
Are winters hard on homes in Janesville?
Yes. Waseca County ranks 47th of 87 Minnesota counties for cold-wave risk. Long cold snaps find drafty windows, and snow that melts and refreezes forms ice dams that push water under shingles.
