A Short History of Angus Theriault & Sons, Inc.
On May 7, 1934, upon the birth of his first child, Angus Theriault drew his first roofing contract, thus starting Angus Theriault & Sons, Inc. Since that day Angus Theriault & Sons has provided Westchester County property owners with prompt, efficient and professional roofing related services.
Angus was joined in his business by his two sons, Joseph and Arthur, who carried on the quality roofing tradition Angus had created for more than three decades. Angus Theriault passed away in 1969. His grandson, Steven Theriault is now the third generation to be a part of the family business.
Angus Theriault & Sons is looking forward to continuing to provide exemplary service in the Westchester area for many years to come.

What our customers say...
We wanted to thank you for the beautiful job on our roof. For the first time in 23 years we have been in the house, there was no water in the basement (except for the last day, and that was due to the ground water level) and last week was surely the definitive test. Dining room also - dry as a bone - and of course it looks georgeous. Thank you. –S.I
