Waterproofing & Green Roof

Waterproofing & Green Roofs in Minnesota

Single-Ply Membranes

Single-ply membranes are leak-proof, energy-efficient, weather-resistant, and low-maintenance. Berwald works with a number of manufacturers to offer a variety of membranes to meet your waterproofing needs. 


Hot Fluid Applied

Hot Fluid Applied is a single-component, hot-applied, rubberized asphalt compound that cures to form a strong, flexible, fully adhered waterproofing membrane. Forming a watertight seal it eliminates water migration and build-up of moisture on the surface of the substrate. We work with the following manufacturers for waterproofing projects.

  • Carlisle
  • HydroTech
  • Sarnafil
  • Barrett

Green Roof

For a truly eco-conscious roofing solution, plant a green roof. There are two options for a green roof system. A green roof system is an extension of the existing roof. The first system involves a high-quality waterproofing and root-repellent system, a drainage system, filter cloth, a lightweight growing medium, and plants. The second system includes pre-planted trays filled with a lightweight growing medium and plants professionally installed over a variety of new and existing roof systems, including waterproofing, single-ply, or built-up. The benefits of green roofs are energy efficiency, longer lifespan of materials, sound insulation, aesthetic appeal, and minimized storm water run-off. All of these benefits can save you money in the lifespan of your building. We work with the following manufacturers for Green Roof projects.

  • Carlisle
  • HydroTech
  • GreenGrid
  • LifeRoof
