Building Envelope Repair, Restoration, Design & Construction

Building Envelope Professionals Group (BEPG) is a consulting firm that helps our clients with difficult roofing, exterior wall, and waterproofing issues (also known as building envelope problems).

Our services range from limited consultation to full-service assessment, design, and construction phase support for complex rehabilitation and replacement projects. In addition, we support new construction and validate systems that meet building requirements from the onset through good design and system testing.

Most people don’t have the experience (or desire) to deal with a structure’s issues or the resources to manage their property’s assets. That’s where we help. We strive to resolve our clients’ pain points, including budgeting for these capital expenses. We solve problems nobody can figure out! BEPG routinely works with:

  • schools, 
  • churches, 
  • government agencies, 
  • commercial and industrial clients, 
  • homeowners associations, and 
  • facility managers.

Roofing, External Walls, & Waterproofing

What is a Building Envelope?

A building envelope is all the external systems that keep out the elements (air, water, heat, light, weather, and noise) and keep in energy.

The primary exterior systems are roofing, waterproofing (below-grade), and exterior walls. An excellent design addresses these areas to ensure the structure operates as designed, meets code, and is energy efficient.

Understanding the big picture

The Building Envelope Puzzle

Think of the different components of a building’s exterior as puzzle pieces. In our experience, most problems happen when the puzzle pieces don’t fit together correctly. In other words, most issues occur where the roof, exterior walls, and below-grade waterproofing intersect.

An inspection or assessment of building envelope function looks at the materials and designs of external systems and their relationships with other exterior systems and the activities within these buildings to identify and resolve issues. Applying building science to analyze the enclosure includes looking at:

  • vapor barriers,
  • air barriers,
  • air quality,
  • heating & cooling,
  • climate control, 
  • and much more.

Building envelope consultants focus on the completed puzzle and how well the pieces fit together to keep the elements out versus a contractor responsible for implementing just one part of the puzzle. The ultimate goal is to create a safe, healthy, and comfortable environment!
