Commercial & Manufacturing
Roofing and restoration for the buildings that keep Connecticut’s businesses running — without disrupting the businesses inside.
Built around your business hours.
Commercial, manufacturing, and retail properties can’t shut down for a roof project. A leak above a sales floor, an aging membrane on a supermarket, a phased roof replacement on a multi-tenant shopping center — these jobs happen with customers, tenants, and inventory in the building. F.J. Dahill has spent generations doing exactly this work in Connecticut: scheduling around peak hours, protecting the space below, and coordinating with property managers and tenants.
What We Deliver.
Built for this work.
Zero-downtime scheduling
Weekend phases and after-close hours — we plan around your operating schedule.
Tenant and customer protection

"They worked around our peak hours, kept the store open every day of the project, and finished on schedule. That's harder to find than it should be."Property Manager · Connecticut Retail Chain
