This archived project documents incomplete membrane seams, poor drain connections, and missing flashing details. The useful lesson is to inspect the workmanship and water path rather than judge a roof by its finished appearance.

What to check first

  • Check patch edges and membrane laps.
  • Inspect every roof-to-wall and roof-to-drain transition.
  • Verify that protective coating is not being used to conceal an unfinished repair.

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.
