Don't Rely on Luck With Your Roof

Roofing Company in Overland Park, Allow Us to Introduce Ourselves

Shamrocks are said to bring good luck, and looking at the success of Shamrock Roofing & Construction, it’s tempting to think we’ve had some luck on our side.

Not only has the business expanded to now eight locations across four states, it was named one of the top 10 Kansas City roofing companies by BloggerLocal, maintains an A+ rating and accreditation with the Better Business Bureau, and has high rankings on multiple review sites. This year, Shamrock was also named one of Kansas City’s 50 fastest growing companies. 

Here at Shamrock Roofing & Construction, we are constantly striving for excellence and to be the best of the best. This pushes us to be successful in our industry, and we are so excited to bring this growth and energy into our new home, Overland Park, Kansas. 

Growing a Legacy

Roofing is in the Armstrong family’s blood. Jim Armstrong started Shamrock Roofing in 1977 as a small business, and his son, Garen Armstrong, took an early interest in the business. Garen took over the business in 2016 aiming to be the biggest roofing contractor in the Kansas City area. Garen credits his father for teaching him the integrity and work ethic required to run a successful business. 

Since 2016, Shamrock Roofing & Construction has expanded to seven new locations throughout the Midwest region, including Nebraska, Iowa, Oklahoma, and Texas. Although the vast majority of Shamrock Construction & Roofing work is residential reroofing, we do offer commercial services as well. Both our commercial and residential divisions are coordinated by our production team, which also gives directives to the maintenance division. 

A few notable projects we have completed include the Williamsburg Plaza Apartments, where we contracted for both new construction and reconstruction, and completing one of the largest barrel roofs in the country — the legendary “Cowtown Ballroom” venue in Kansas City. 

We are well-rounded in our expertise and offerings. Shamrock Roofing is a GAF MasterElite roofer, Certified Residential Contractor with Malarkey, Master Shingle Applicator with CertainTeed, an Owens Coming Platinum Preferred Contractor, and a DaVinci Roofscapes roofer. 

Here at Shamrock Roofing, we pride ourselves in our training program which we have established to maintain so many prestigious accreditations. To keep our employees at the top of their game, we have founded a unique training portal called “Shamrock University” that offers continuing education to keep our practices consistent. We use multiple training resources for different aspects of the business and the many different responsibilities of our employees. This includes training on safety practices and our safety policy & program. Every project manager is fully trained in Occupations Safety and Health Administration regulations and know that they are expected to adhere to these protocols on every jobsite. We even include customer service training as this is a high value for us. 

The value we have placed on learning & development, customer service, and safety has created a consistent company culture of strong teamwork and growth for our employees both personally and professionally.
