Learn about Our Minnesota Commercial Roofing Experts

Roofing technology is constantly changing, with the development of new coverings, insulation materials, and innovative application techniques. Commercial clients demand a roofing contractor that has the expertise and knowledge to ensure quality installation that lasts. Integrated, high-performance building materials and systems of proven capability installed by skilled professionals are essential to provide optimum roof performance, maximum life cycle and cost advantage. Berwald installs only commercial roofing systems from major manufacturers with proven track records of the highest standards. If you must repair an existing roof, let a representative from Berwald evaluate your roof and make recommendations with custom specifications to fit your needs. We will remove the old membrane and dispose of it according to local and federal regulations. We will handle all removal of existing plywood or sheathing and do all the flashing, plumbing and mechanical work to ready your building for a new membrane. We offer the following roofing systems to our commercial roofing clients:

1Standing Seam Metal Roofing

A standing seam roof is constructed of interlocking panels running vertically from the top of the roof to the eave. The interlocking seam where two panels join together is raised above the roof’s flat surface, allowing water to run off without seeping between panels. Standing Seam Metal Roofing is increasing in popularity every year due to its unmatched durability and investment value. We work with the following manufacturers for architectural metal roof projects.
  • Firestone Una-Clad
  • Coated Metal Group Ultra-Clad
