Area alone does not explain the work involved in a roof repair. Access, railings, siding, skylights, drains, and concealed damage may matter more than the difference between a residential and commercial building.

What to check first

  • Count the transitions and penetrations.
  • Consider safe access and material handling.
  • Ask for a scope based on the actual defects rather than a universal price per square foot.

Evaluate the complete roof assembly

  1. Inspect what is beneath the surface

    Wet insulation, damaged decking, unsuitable attachment, and trapped moisture can change the scope of work. A new top layer cannot restore deteriorated supporting components.

  2. Plan the transitions and drainage

    Coordinate edges, parapets, penetrations, drains, and overflow routes with the selected system. These connections are part of the roof, not finishing details to improvise later.

  3. Use a building-specific specification

    Follow the selected manufacturer’s assembly requirements and appropriate professional review. Torch application, structural changes, and concealed damage need qualified personnel rather than a general DIY recipe.

Watch the field examples

These archive demonstrations show individual projects. Use the current guidance above and Bergstrom’s published instructions if an older video shows a different product or method. Torch work shown in installation videos is professional work.
