Why Waukegan
TESTIMONIAL
Our department is very grateful for the professional job your company completed here at the Waukegan Fire Department. Please express our great appreciation to your staff/personnel, and we look forward to working with Waukegan Roofing in the future.
Thank you for years of excellent service! Randy is amazing and goes the extra mile when it comes to excellence in service!
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.
I was very impressed with the technical knowledge, professionalism, follow-up and communication. This is a first class outfit. Waukegan is top tier. They are a cut above the collective competition out there.
They put a new roof on my house 3 years before I bought the house. Then 2 years after I bought the house one of the plywood sheets lifted off a little creating a hole in the roof. A big problem. So I called and they had a crew out to fix it–no questions asked–within a few days. No charge, even though it was a few months out of warranty and even though I was not original customer. I was pleasantly surprised a company actually stands by their work like that–even five years later. They even inspected the whole roof and fixed another small issue I wasn’t even aware of.
What sold me on them is their honesty. We thought we were going to need a new roof. They could have sold us one, but the Waukegan Roofing representative who came over let us know that we didn’t need to replace the roof…we just needed a simple repair. We were impressed with their honesty, even though it resulted in a smaller job and less revenue. We have been sold ever since. The work they have done has been high quality too.
The immediate action taken by Waukegan Roofing once the problem was recognized speaks volumes about Waukegan Roofing and the willingness to take care of their customers. It is one thing to complete another construction project, but it is a completely different thing for companies to stand behind their work and make corrections when the customer needs you most.
