We’ve taken this motto to work with us every day for over a decade, because the durability and integrity of a new roofing or siding project are defined by the detail & integrity with which the materials are installed.

We do the job right the first time, every time, and we treat each home as if it were our own. We don’t cut corners (well, you know what we mean!). Our reputation is only as good as our work – not just on the day the job is done, not just one year later, but for years to come.

Our thousands of happy Chicagoland homeowners are a testament to why we go the extra mile: because Details Make the Difference.

We don’t hide behind stock photos. Please enjoy our original content – our work speaks for itself!


When is the last time you had a contractor do exactly what they said they were going to do?

I cannot speak highly enough of my experience with Lang Home Exteriors. I was amazed at how organized and hard working the crew moved for the 2 days that job took to complete. Then the best part happened! After they left, my yard was immaculate. I did not find one piece of material left behind! I have been a homeowner for 25+ years and have used many contractors over those years. Lang Home Exteriors is a notch, no 2 notches above the average contractor.

“I have used Lang Home Exteriors a number of times for roofing, siding installation, insulation, soffit/fascia/gutter replacement and have had an excellent experience from start to finish on every project. Bill Lang, the owner, is a true professional as have been his workmen and office staff. Each job was on time, done to my satisfaction and within budget. I highly recommend this company!”

Susan, Western Springs, IL


“We had a new roof, siding and gutters put on our home. Our LP siding was installed by professional craftsmen with strong work ethics. The talented crew worked efficiently making sure all seems and nails were installed and aligned correctly after putting in an honest days work. Lang helped us stay within our budget by recommending 2 phases of our project. Great idea!

The best part of our project is not only the amazing look of the house but the physical stability of our home. No more water leaks around doors and windows and no more movement or noise when the brisk Chicago winds break loose.”

Nikki, Lansing, IL
“Excellent, professional sales and service with years of experience. My roof is 10 years old now and still looks new. It has held strong through some tough windy winters here in Chicagoland! I have recommended Lang to others, all of whom have had the same 5 star service!”
Clara, Oak Forest, IL
“Bill Lang is a stand up guy with old fashioned principles (something you don’t see very often nowadays). I just had my siding, facia, soffits and gutters replaced. His crew worked hard from start to finish. No messing around! Excellent job! I will be recommending them to anyone I know that needs exterior work on their home.”
Gail, Lisle, IL
“Lang Home Exteriors replaced my shingles, gutters, downspouts, soffit and facia. I recommend them to anybody wanting to get this type of work done. Everyone in this organization is very knowledgeable, professional, courteous and helpful. It was a pleasure working with everyone involved with this company, from Daniel, my salesman, to the contracting teams that did the labor, to the delivery drivers. We are extremely happy with the end results.”
Peotone Park District
Bill was very professional and expedited a quote for me. No pressure and made some suggestions for me which I appreciated. They removed the gutters, soffit, fascia and siding and replaced it with all with a very talented and polite crew. The job was spotless at the end of every work day. They did a very good job, and I wouldn’t hesitate recommending them.”
Lawrence, Palos Heights, IL


“Fantastic company to work with. Our main building needed a major facelift. We went to Bill, he was very knowledgeable and gave us the right suggestions for what we were looking for. He helped bring our ideas to reality. Bill came out throughout the week to keep us updated and having his presence throughout the project was very comforting, explaining what was being put where and why. The project was completed in a week and they were great to work with. I highly recommend this company for any business or residential projects. Wonderful job all around!”

Ralph, Palos Park, IL


“They are amazing. Not only does my house look phenomenal but they were just the nicest people to work with; very friendly and kind. Bill came by to ensure the job was on track, he answered any questions I had and made sure I was satisfied. He took the time to go through the catalogue with me when picking out my siding. I highly recommend this company.”

Sara, Lemont, IL


“Lang Home Exteriors was very professional walking us through the entire siding process from the the quote through the completion of our installation. The entire project went as described, from the delivery of materials to the start time of the crew. Our installer spent time outlining his steps for the workflow from start to the siding project clean-up. The siding project was actually completed earlier that projected and looked GREAT. I would recommend Lang as well as use Lang for any future projects!”

Paul, Frankfort, IL


“Great company! They gave a few options in written quotes, answered all our questions completely and offered their recommendations. They treated us with respect and completed the job as discussed, in the manner promised. Would recommend!”
