Justin provided quick service and detailed responses to the roof inspection I requested.Posted on Chase JudaTrustindex verifies that the original source of the review is Google. Excellent service. I had both Reed and Mack come out to help with a roof inspection. After I called and provided some basic information, they were able to come out within just a couple of days. Reed and Mack walked the entire roof, took photos, and carefully inspected the areas of concern I had pointed out. To my surprise, no work was needed. Instead, I received reassurance, a detailed report (which they went out of their way to provide over the weekend), helpful advice, and valuable industry insight. Deeply appreciative.

I had a great experience with Reed and Mac from Shamrock Roofing. They were extremely polite, professional, and took the time to thoroughly explain what was going on with my roof in a way that was easy to understand. I never felt rushed, and they made sure all my questions were answered.

Over ten thousand roofs replaced since 1977. Our Lawrence team brings that depth of experience to every project—residential or commercial, simple or complex.
If a repair can extend your roof's life, we recommend it. If replacement is the right call, we show you the inspection data that proves it. Zero pressure, every time.
Materials, scheduling, insurance paperwork, installation, and cleanup—we handle every detail so you can focus on your life, not your roof.
Shamrock isn't a fly-by-night operation chasing storm damage across the plains. We have permanent roots in Kansas and stand behind every roof we install in Lawrence.











Most residential projects in Lawrence range from $8,000 to $25,000 depending on roof size, pitch, material selection, and complexity. We provide a detailed written estimate after every free inspection.
If damage resulted from a covered event like hail, wind, or tornado, your policy may cover part or all of the replacement. We provide comprehensive documentation and work directly with your adjuster throughout the claims process.
