Flat Roof Doctor grew from the Ferreira family's roofing work into a library of practical repair demonstrations. Naas and Mia Ferreira came to the United States from South Africa in the mid-1980s, and the family's roof projects became the foundation of the video archive.

What to check first

  • The archive preserves real repair details and lessons from field work.
  • Today's site focuses on education, material identification, and product guidance.
  • Current Bergstrom instructions take priority when older videos show a different product or method.

How to use the field archive

  1. Learn from the diagnosis

    Notice which details were inspected and why the suspected defect mattered. Those observations are useful even when your own roof needs a different repair.

  2. Check the current instructions

    Products and guidance change. Compare historical demonstrations with the current Bergstrom catalog before selecting materials or repeating a method.

  3. Apply the lesson to your own roof

    The archive documents individual projects. It does not promise the same outcome, service life, or repair suitability for every building.
