Shamrock Roofing acquires Bob Hamilton headquarters in Overland Park
October 26, 2023

The new acquisition

Shamrock Roofing and Construction will acquire the Bob Hamilton headquarters building in Overland Park.

Bob Hamilton was founded in 1983 and acquired by ARS in 2017. Last month, the HVAC company changed its name to Bob Hamilton Plumbing, Heating, AC, Rooter & Electrical as part of the parent company’s consolidation.

In January, Shamrock will take over its 15,000-square-foot office space at 10231 W. 79th St.

The roofing company has 11 locations across the Midwest and plans to add five additional locations by the end of 2024.

Between 2020 and 2022, the company’s average annual revenue growth was about 47.5%, according to the Kansas City Business Journal List of fastest-growing local companies. Its revenue in 2022 was about $32.8 million.

“We’ll hit close to $50 million (in revenue) this year, and we’re going to be growing to $250 million. That’s why we have the new acquisition,” Shamrock President Garen Armstrong said.

The new Shamrock Roofing technology

Shamrock will maintain its current office at 7899 E. Frontage Road in Overland Park and use the new facility, which is across the street, to support the research and development of its new Customer Relationship Management System software.

“That’s being developed by developers here in Kansas City,” Armstrong said. “” is the name of the software that is going to be running Shamrock.”

Armstrong said the company already uses some of the software’s features to support customers payment portals, but the new system will be more comprehensive. The software will be integrated with the National Oceanic and Atmospheric Administration to track weather systems and potential storm damage in Shamrock’s service area.

The technology will be used to schedule inspections after severe weather events and help the Shamrock team evaluate what customers may need based on their location.

“We can know what climate they’re in and if they need an impact-resistant roof or a more durable roof,” Armstrong said.

It also will help Shamrock know what materials to use on the job site.

“That’s able to help us, based off the percentages of damage, start the procurement process of ordering materials such as shingles, OSB, so we have them on the ready to start all the reroofs we’re going to be doing,” Armstrong said.

Shamrock is expected to close on the building acquisition in December. The official price of the sale was not disclosed, but Armstrong said it will purchase the property for just under $4 million.

Tyler Schell, with RE/MAX, represented Shamrock, and Joel Hutchines, of Hutchings/Carrier Inc., represented the seller.
