Commercial Roofing
Flat, low-slope, slate, and metal roof systems for Connecticut’s institutional, industrial, and municipal buildings.
Roofing for buildings that matter.
F.J. Dahill has been a roofing contractor for Connecticut institutions since 1883. We work on the roofs that protect university and college campuses, hospital facilities, industrial and manufacturing plants, retail shops, warehouses, houses of worship, municipal buildings, and condominiums. We bring 143 years of roofing craftsmanship to every project, whether it’s a new install, full tear-off and replacement, or a critical emergency repair.
