This archive project illustrates the coordination needed between a new roof, its perimeter walls, and its drainage openings. Details from one project are examples, not a universal specification for other buildings.

What to check first

  • Coordinate roof height and slope with scupper openings.
  • Plan wall terminations and cap details.
  • Use a building-specific assembly and required professional review before construction.

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.
