Installation footage can help building owners understand the details that later need maintenance. Pay attention to curbs, edges, drains, and wall terminations, not only the broad field of membrane.

What to check first

  • Check flashing continuity around equipment.
  • Verify compatible drain connections.
  • Keep records of materials and completed details for future repairs.

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.

It took many people to strip this flat roof in Greenwich. Care must be taken not to ruin the flashing around the drains and skylights.
