This archive project shows a roof being recovered. Whether that approach is appropriate elsewhere depends on the condition and construction of the existing roof, not simply on the fact that another layer can be installed.

What to check first

  • Investigate trapped moisture and the condition of insulation.
  • Assess decking, attachment, and added load.
  • Obtain a building-specific scope that explains why recover or removal is appropriate.

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.
