Alliance Roofing & Sheet Metal 2016 Case Study

Alliance Roofing & Sheet Metal Ltd. was founded by Glenn Schwantz in 1999 with a goal of installing high quality commercial roofs in Ontario. Alliance Roofing joined the Firestone network of licensed contractors in June 1999 and since then have completed over 290 Firestone roofing projects all across the province. Loblaws, Best Buy, Canadian Tire, and countless others have all relied on Alliance Roofing for high performance roofing systems.

Alliance’s Focus on Communication

With a focus on large scale projects ranging anywhere from 20,000 ft2 to over 700,000 ft2, Alliance roofing owes their success to their open communication policy which allows them to stay on track and meet very stringent deadlines. Internally and externally, all members of the Alliance roofing team work diligently to ensure important notices are communicated effectively at all levels. Especially for large scale projects that have countless moving targets. Externally, the building owner and GC for any project is always aware of the progress that has been made on the roof and is notified of any updates. Internally, Alliance’s 100% open door policy encourages teammates from all levels to speak freely and share their opinions, which allows management to learn of any inefficiencies in the company and determine ways to make smart changes.


Quality Service

The team at Alliance roofing is composed of 15 office staff and nearly 80 contractors who work in the field; and all of whom deeply value the quality of roofs that they install.

Quality is always important at all levels of the company. We have consistently installed single-ply roofing systems at a very high level for the last 16 years and it has been the basis for the company ever since Glen Schwantz started operations in 1999.” – Matt Varga, Estimator – Alliance Roofing & Sheet Metal Ltd.

Contractors at Alliance roofing are regularly refreshing their knowledge about RubberGard™ EPDM and UltraPly™ TPO systems by attending Firestone Quality Seminars which combines classroom activities with hands-on training. They are eager to learn of any product changes and understand correct installation techniques. As a result it comes to no surprise that Alliance roofing has become one of Ontario’s premier single-ply installers and a Firestone Master Contractor twelve times.

Alliance Roofing is experienced in managing and installing large scale roofing projects. With fully qualified crews and years of experience they are able to efficiently tackle large jobs with ease.” – Todd Perry, Firestone Technical Representative – Southern Ontario
