Septagon Construction | General Contractors & Roofing in Sedalia, MO 65301

Our process begins with a detailed architectural site analysis specific to your Sedalia property, considering local zoning, soil conditions, and environmental factors. Our architects then work directly with you to design a functional space that meets your business needs. Because we are a design-build firm, this team stays involved throughout the entire construction phase, ensuring the original vision is executed precisely by our own carpentry, concrete, and ironwork crews, which leads to smoother projects and consistent quality control.

Our architectural project management provides a single point of responsibility from concept to completion. Your assigned project manager oversees the entire build, coordinating between our in-house design team, engineers, and skilled tradesmen. This integrated approach, honed over 70 years in the industry, ensures timelines are met, budgets are maintained, and our high standards for safety and craftsmanship are upheld at every phase, giving you peace of mind throughout the construction of your commercial or industrial facility.

Absolutely. For commercial buildings in the Sedalia area, issues like roof flashing lift and skylight leaks are often due to material fatigue and our local weather patterns. As part of our architectural site analysis and project management, we specify and install robust, weather-resistant flashing details and properly integrated skylight systems from the outset. For existing buildings, our skilled tradesmen can diagnose the root cause—often improper installation or material failure—and perform lasting repairs using quality materials suited for our Midwestern climate, preventing water damage and protecting your investment.
