Gag Sheet Metal, Inc.,

Southern Minnesota's Oldest Roofing & HVAC Business

Gag Sheet Metal, Inc. is a family owned company located in New Ulm,
Minnesota. The company was founded in 1904 by George Gag, and
carried on by his son Melvin Gag. Mel’s son Michael Gag became an
owner in 1978. In the Mid 1980’s, his son John Gag joined him, and in
the early 1990’s, Mike’s son Steven Gag joined the company. John Gag
is the current owner, and with his brother Steve, head up the
management team. In 2006, we merged our two southern Minnesota
offices, moving into a larger building, with remodeled offices and building
a new shop and warehouse in New Ulm.

In 2015 Gag Sheet Metal Inc. purchased Schanus Plumbing & Heating in
New Ulm and Isakson's Plumbing in Gibbon, MN to further expand their
customer service.  In 2016 a Gag Sheet Metal branch was opened in
Hutchinson, MN to create a location specific to our northern service
customers.

We install all types of roofing, specializing in Flat roofing and
Architectural Panels. Our HVAC side of the business works with all types
of ventilation, as well as commercial kitchens, and in-floor heat.

Gag Sheet Metal Inc. is Minnesota's longest Bryant Heating and Cooling
systems dealer and have been recognized for years as one of the best
HVAC systems installation and service company.

GSM, has been serving southern Minnesota for over a century.  More
than just sheet metal, we specialize in commercial, Iowa, Wisconsin, or
North Dakota.
