Why Waukegan
TESTIMONIAL
Please pass our thanks on to your team who were personable and, as far as I can tell, very thorough and careful in their work. It was greatly appreciated.
The great roofers who make up this company are competent, professional, trustworthy and honest. They never try to gouge anyone, but are very fair with pricing.
Thank you for years of excellent service! Randy is amazing and goes the extra mile when it comes to excellence in service!
Had a roofing job that needed to get relooked. Bruce sent a tech out that very morning. He found out what it was and made the repair in the rain! Waukegan Roofing stands behind their work! Would definitely recommend them to friends & family.
Very satisfied with the service that Josh at Waukegan Roofing provided. We had a small leak in our roof and for months, I tried to find it, but with no success. I called Waukegan Roofing to come out and take a look. Within 15 minutes, Josh not only found the small leak, but quickly caulked it and took care of the problem. What I also liked was that Josh could have reshingled the whole area at a much higher cost. But he felt that this was needed and that a good caulking job would seal the hole. I would recommend that you give Waukegan Roofing a call if you have any roofing needs.
I would recommend Waukegan Roofing to anyone! The quality, attitude and special attention to detail was appreciated. The cleanup was amazing! I would recommend Waukegan Roofing to anyone!
Your employees just finished 2 jobs here at our location: sealing leaks along a stretch of windows up on our roof and most recently repairs to and applying an aluminum colored coating to our corrugated metal east warehouse roof. I normally do not write to anyone about the workmanship of a job done here, but in this case I thought it’s something that I should do, especially in this case.The workmanship of the repairs was absolutely outstanding. The crew did a fabulous job of repairs & applying the aluminum colored coating to our corrugated metal east warehouse roof.All your workers were very professional in their conversations with me. Thanks very much for the jobs very well done.
