About Us


History of Kline-Johnson & Associates

The company known today as, Kline-Johnson, Building Envelope Choices, was started in August of 1979 by Ken Kline, and was known as KR Kline & Associates. From the very beginning the company focused on representing quality manufactures of thermal and moisture protection building materials to the architectural and contractor communities of Minnesota, North & South Dakota.

In 1980, Ken became affiliated with Firestone Building Products Company who, at the time, was just beginning their long and successful journey into the manufacturing of membrane roofing systems. Today, Firestone Building Products Company offers a full line of roofing membranes including; EPDM, TPO, Modified Bitumen, and BUR systems. To complement the roofing membranes, Firestone also offers all installation accessories, flat and tapered roof insulation as well as architectural sheet metal systems. Firestone’s recent acquisition of Gaco Western adds a sophisticated line of coatings to the product line. Kline-Johnson has the honor of being the longest-tenured independent representative of Firestone Building Products Company.

During the ensuing decades, Kline-Johnson has added lines to round out our selection of materials for the building envelope. These manufacturers include: GenFlex - single-ply roofing systems, Kemper - high performance waterproofing, Protean – metal wall panel systems, USG – SecureRock gypsum fiber and glass mat roofing boards, RoofTop Anchor - permanent fall protection anchors, combined with SafePro – automated roof hatches with built in fall protection provide a full array of roof top safety products. These products allow us to provide comprehensive assistance with the building envelope.

Today, Kline-Johnson has 11 full time associates, 4 inside sales and 7 outside sales. Eric Johnson has taken the company over as President and Ken serves as Chairman of the Board. We are honored to have been able to serve the construction community for the past 39 years and are looking forward to many more.
