About Us

We at Hahnel Bros. Co. have been in the business of keeping people safe, dry, and warm since 1916. We are also Maine’s premiere roofing and architectural sheet metal company. Because of our team of highly-skilled foremen, Hahnel Bros. Co. can provide our customers a virtually unlimited array of custom roofing and sheet metal orders.

From the beginning of low slope roof designs, we have been the company manufacturers turn to when introducing and promoting their products. Our competitive edge is our superior workmanship, with decades of experience behind it.

While Woodrow Wilson was President, Oscar & Frederick Hahnel bought the Lewiston Metal, Cornice & Skylights Works. Hahnel Bros. Co. has given business owners and the public peace of mind about staying dry within their buildings, for all the years hence.

With the company’s expansion through a partnership with Bangor Roofing & Sheet Metal Co. during the FDR Years, we extended that peace of mind to property owners. We recently solidified that comfort with the corporate merger of the two companies in 2005.

I think Hahnel Bros  Co. did an excellent job at meeting our expectations and was always communicating and showing a lot of pride and willingness to do the task at hand right the first time.
