Roofs Built for Bureau County Weather
Open farmland around Princeton means wind, driving rain and drifting snow hit buildings hard. Flat roofs that hold water are especially prone to freeze-thaw damage. Duro-Last’s heat-welded PVC membrane is wind-, puncture-, chemical- and fire-resistant, while a properly insulated Duro-Last roofing system can improve energy efficiency—helping keep heat in during the winter and cool air in during the summer. It’s a smart choice for retail, warehouse, agricultural and manufacturing buildings.
