Williston, VT – Commercial Roofing Contractor – AC Hathorne, A Tecta America Company

 Commercial Roofing Contractor in Williston, Vermont

A. C. Hathorne is very proud of its reputation in the commercial roofing Industry.  From its founding in 1875, our company has put one consideration before all others: to provide a roofing system that we will stand behind and that best exemplifies our reputation in the region. Everyone involved is conscious of this A.C. Hathorne priority.

At A.C. Hathorne, our recommendations answer these basic questions: What is the most practical roofing system to use? What will its performance be? As maintenance is expensive, how much upkeep will this system require? How will the roof affect the aesthetics of the building? How will it affect energy conservation? How much inconvenience will this installation cause the owner during the roofing process?

Our experience with all types of applications – such as copper, slate roofs and solar, as well as single-ply roofing of EPDM rubber and PVC – allows the roofing division to handle any project with skill.

Our staff and craftsmen work on all types of buildings including industrial, institutional, commercial, and residential. A.C. Hathorne has provided roofing systems in a variety of locations throughout New England and New York State.


Our services in roofing, suspended ceiling, drywall, and HVAC ductwork construction are typically performed in the New Hampshire, Vermont, Massachusetts, Southern Maine, and Eastern New York areas.
