The archive introduces several common roof coverings, including EPDM, thermoplastic membranes, and modified bitumen. Use the examples as a starting point; confirm your roof's exact material before applying a repair product.

What to check first

  • Do not identify a membrane by color alone.
  • Remember that TPO and PVC are different materials.
  • Read current compatibility instructions even if an older video uses the word rubber broadly.

Identify the roof before selecting a product

  1. Use reliable identification

    Look for installation records, membrane markings, or a qualified assessment. Color alone cannot reliably distinguish EPDM, TPO, PVC, or a coated asphalt surface.

  2. Identify any previous coating

    The material a sealant touches may be an old coating rather than the roof membrane. Product compatibility must account for that exposed layer.

  3. Confirm the current repair detail

    Review the manufacturer’s instructions for both the substrate and the type of defect. An installation demonstration is not a substitute for a suitable localized repair method.

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.
