Hamilton HS Roof Replacement 2026

The north fine arts wing at Hamilton High School went into the 2026–27 school year with two new rooftop air handlers and a new roof beneath them, all replaced in one summer while the building was empty. Prodigy delivered the whole package under one contract: HVAC engineering and equipment selection, a new structural steel platform, crane work, chilled- and hot-water piping, ductwork, Automated Logic building controls, and an 80-mil Carlisle TPO roof carrying a 30-year warranty. Hamilton City School District bought the work through the TOP-C cooperative, a competitively bid unit-price contract, which let the district approve the project in November 2025 and have the air handlers on order by the first of December.

The air handlers and the roof were due at the same time, and doing them together is what made the schedule work. A crane took the old units off in early July and set the new ones the following week, while the roofing crew worked through the wing's roof sections around them. Because the new units stand on steel above the roof, the new membrane runs under the equipment instead of around an old curb, and nothing will have to be lifted off it when the roof is next worked on. The crew also removed 18 abandoned curbs, filled in the deck, and added tapered saddles to drain an area that had been holding water.

The new equipment is two Daikin Rebel air handlers of about 27 and 20 tons, serving the wing from the school's existing chilled-water and hot-water loops. Both run variable air volume with an economizer that uses outdoor air for free cooling when conditions allow, carry MERV 14 final filters, and measure their own outdoor airflow and the carbon dioxide in the air they return. New ductwork is sloped to shed water and aluminum-jacketed to match what was already on the roof, and the piping to the coils is heat-traced for the coldest nights. The units report to new Automated Logic controls, with graphics, alarms and trending in WebCTRL for the district's maintenance staff.

What the district has now is a fine arts wing with new equipment on a new roof, set up so that the next roof replacement does not start with a crane. For a district with rooftop air handlers and a roof both getting close to their dates, the lesson is to look at them as one project: the crane, the curbs and the sequence are shared, and so is the opportunity to fix how the equipment sits on the building.
