The Choice of More Fortune 500 Companies
The Most Trusted Roofing Company Since 1920

The Kirberg name has always stood for high-quality roofs of lasting value, and we're proud to carry on this tradition of excellence and innovation as an industry leader in green roof construction in St. Louis, Kansas City and Springfield. The term "green roof" stems from the roof's renewable energy design and usually refers to a rooftop garden, typically on a commercial building.
Green roofs, or rooftop gardens, provide your business with an excellent opportunity for long-term cost savings and positive return on building investment. Our lightweight, low-maintenance green roof systems (rooftop gardens) turn ordinary roofs into natural, beautiful "roofscapes" that reduce stormwater runoff, provide volume insulation, improve air quality and conserve both natural and financial resources as a result of a reduced heating and cooling demand.
By harnessing the power of the sun, solar panels create and store clean, carbon-free electricity that can be used to meet your energy needs and drastically reduce energy costs. Hurricane-proof, lightweight panels adhere to the roof without additional supports and fasteners - leaving your roof warranty protection intact. The tax incentives, savings, and revenues gained from implementing commercial solar systems can pay for itself in just six years. During its 25 year guarantee, our solar roofing can offer over a 100% return on investment.
By lowering the surface temperature of the roof, our reflective roofing systems decrease the amount of heat transferred into your building. This translates to a reduced need for air conditioning during peak cooling periods and therefore can result in significant savings on annual energy costs for your business.

The financial benefits of going green just became a bit clearer with the introduction of Kirberg Company's Helios Monitor.
The Helios Monitor offers the ability to calculate savings of unused energy that can be sold back to the utility companies and can be installed on existing roofs with Photovoltaic (PV) Panels or with a new roof install or repair.
The new monitor measures Photovoltaic Panel output, and converts it into a visual display that provides instant energy-output data, thereby enabling businesses to "watch their green grow" in real time. With the Helios Monitor, businesses can identify exactly how much energy theyíre saving with their Photovoltaic Panels, and how much that energy savings is contributing to their bottom line.

The Kirberg Helios Monitor takes the mystery out of solar energy savings by measuring the output from your Photovoltaic Panels and converting that number to an easy-to-read, visual display of current kilowatt output, as well as daily weekly, monthly, and lifetime kilowatt production. The real-time energy reports are then converted to demonstrate the environmental impact of your energy savings in equivalent terms of:
You can calculate your money savings with the Kirberg Helios Monitor by using the following formula:
Kilowatt hours (kWh) per year x the average value of electricity. In Missouri, the average value of electricity is six cents ($.06) per kWh.
