I had a time sensitive repair that needs to be done. Ian made it happen. One word. Amazing! He made it happen! Great communication, punctual, and professional. Ian, You're the best!
Working with Omega Exteriors was such an easy process. William handled everything, and I mainly got to focus on choosing colors and the final look. He made it simple and helped us pick something that turned out amazing. We love how our home looks now!
State Farm approved our roof and gutters after the hail storm but initially denied full siding. William at Omega Exteriors stepped in, handled the process, and got everything fully approved. Insurance claims can be a headache — having someone experienced on your side makes all the difference. Highly recommend. Before and after photo’s

Which office serves Janesville?
Our Menomonee Falls office at N50W13916 Overview Dr, Menomonee Falls, WI 53051, about 55 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 17 times in the years from 2016, most recently in August 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 the 4 ZIP codes that cover Janesville was built in the 1970s, 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. Rock County ranks 22nd of 72 Wisconsin 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.
