T & K Roofing Company

What T & K Roofing Company does

T&K Roofing and Sheet Metal Inc. is a second-generation, family-owned commercial roofing and architectural sheet metal contractor headquartered in Ely, Iowa, founded in 1962 by Tom Tjelmeland and currently led by President/CEO Kurt Tjelmeland. The company provides end-to-end roofing and exterior envelope services spanning low-sloped membrane systems (TPO, EPDM, PVC, modified bitumen, built-up roofing), standing seam metal roofing, steep-slope applications, architectural sheet metal fabrication, wall and siding systems, green roofs, plaza deck roofs, fluid-applied waterproofing, and historical metal renovations. Underlying capabilities include in-house sheet metal fabrication, design and budgeting assistance provided to general contractors and designers, and a Department of Labor-registered apprenticeship program delivered in partnership with Roofers and Sheet Metal Workers union locals. Service is delivered across a five-state Midwest territory (Iowa, southern Minnesota, western Illinois, eastern Nebraska, and northern Missouri), with named customers including Quaker Oats, Kinnick Stadium (University of Iowa), Hancher Auditorium, Cedar Rapids Central Fire Station, and Marion YMCA.

The business operates a hybrid revenue model. The dominant stream is project-based commercial roofing installation, re-roofing, and renovation generated through competitive bids and direct engagement with building owners, general contractors, and designers; this is supplemented by recurring revenue from preventive maintenance service contracts priced at fixed hourly rates ($500-$2,500 per service session) covering inspections, snow removal, power washing, leaf cleanup, and ongoing roof care. Go-to-market is enterprise field sales, supported by manufacturer Master Contractor designations (Elevate/Firestone, GAF, Fibertite, Johns Manville) that expand bid eligibility across material systems, and by trade association participation (MRCA, NRCA, IRCA) and a multi-channel digital presence (website, blog, Facebook, LinkedIn, Instagram). T&K's safety program, with a dedicated full-time Safety Director and OSHA-10 requirement for all field staff, has earned 11 consecutive MRCA Platinum Safety Awards (2014-2024) and maintained an Experience Modification Rate of 0.65-0.71 over 2016-2025, below industry average, functioning as a competitive credential in safety-sensitive institutional bidding.
