A Company You Can Count On

Because Sielfleisch Roofing is locally owned and operated each roof we work on gets detailed attention from our owners and senior managers. We employ only union crews who have worked together for years and know what roofing systems work best for this area.

Specialized teams, like the “hot” team”, the “rubber” team, and the “heat welded” team, focus their attention on what is right for that specific roof.

Mark Sielfleisch has worked on roofs in the Midwest since 1966, when he began his career as an apprentice roofer. Sielfleisch Roofing has a long history of providing St. Louis area customers with high level customer roofing services.

Vice-President Dan Smith is a roofing expert with over 25 years of experience in all aspects of the roofing business.
