about the roofing professionals at KM ConstructionKM Construction is a family-owned roofing contractor dedicated to serving the needs of McHenry County and the surrounding areas. Our small-business attitude means customer satisfaction is our top priority—we take every opportunity to ensure that our clients are receiving the very best roof work possible, and 95% of our customers are residential. Be it a sectional repair or an entire roof replacement, KM Construction has the tools to guarantee a superior final product. We treat our clients like family giving fair pricing and warranties to back up our work.


Every product we install is of the highest quality material and labor. Many competitors choose to use cheap “architectural” shingles / products that may cost thousands of dollars less from a big box retailer. We use commercial grade accessories and building materials that have the reputation and warranty behind them to last a lifetime. Our employees are trained to install all products according to manufacturer’s specifications and providing you a peace of mind installation.

Customer Service

Starting in 1999 our founder Ziggy Wierzba had a motto “treat everyone like family and do the job right the first time” This still holds true today, as our business grows we still remember that our customers need friendly service, expert advise, and rapid response times. We try to turn around most quotes in 24 hours and follow up with our customers to let them know how their roofing, siding, and gutter project is going.


Being a family owned and operated business we are not driven by profit and investors. We are dedicated to treating customer’s fairly and being part of the community. KM Construction Inc. is active in school sponsorships and sponsoring the McHenry River Run. We believe that being present in the community is important. We take care of every single customer and should they have a problem we work to resolve it quickly.


Continuing education and seminars is how we make sure we are providing the best advise on new products. Our staff is trained to answer questions and provide advise on the best roofing, siding, and gutter materials for your project. Our employees are required to attend safety and manufacturing training seminars to ensure proper installation of all products. Since 1999 we have been installing new roofs in Illinois.
