Brookhaven Town Hall needed to be re-roofed due to the UV damage to the existing roof surface. The existing roof was a 20-year-old, granular-surface built-up system that held a lot of trapped moisture. The building would be receiving a new photovoltaic (PV) solar tray system, and this was another driving force in the decision to re-roof. The Town Hall would be open and occupied during the re-roofing project, so it was important to keep noise and odors to a minimum.
The proposal called for a tear-off down to the existing vapor barrier installed over the structural concrete deck. The new roof system would be a fully adhered TPO system from Versico featuring APEEL Protective Film.
Statewide Roofing, a leading commercial roofing company based in Ronkonkoma, New York, was selected to put the new roof on the Brookhaven Town Hall. With decades of experience on all types of roofing projects, the professionals at Statewide understand how to work with all types of buildings and materials.
The Brookhaven Town Hall would be installing its new photovoltaic (PV) solar tray system after the re-roofing project was complete, so it was important to install a roof that would support the PV system while providing long-term protection for the building and its occupants.
A Versico contractor since 2013, Statewide Roofing suggested a 60-mil white VersiWeld TPO membrane with APEEL Protective Film for Brookhaven Town Hall’s 95,750-square-foot roof. The membrane would be fully adhered to a 2-inch-thick layer of SecurShield HD Composite Board, which itself would be adhered to a base layer of 3.3-inch-thick VersiCore MPH Polyiso.
The town hall roof had large, open areas that made it ideal for 12-foot-wide TPO sheets, which would make the installation go faster and save time, labor, and money. Statewide selected a TPO membrane with APEEL Protective Film, which guards the roof from dirt during installation and eliminates the need for pressure washing at the end of the project.
The insulation adhesive was Flexible DASH, a two-component, construction-grade, insulating, polyurethane adhesive with a quick, quiet, low-odor application. “Flexible DASH was ideal,” says Tim Curtin of Statewide Roofing. “Over the existing asphalt roof, they adhered a base layer of 3.3-inch polyiso. After that they installed a top layer of 2-inch SecurShield HD Composite, which saved the time and labor of installing the polyiso and cover board separately. The new TPO membrane was adhered with CAV-GRIP 3V Adhesive, so that made it easy to install. The APEEL membrane was used with great success.”
