EPDM is one of several established low-slope roofing materials. A fair comparison looks at the assembly, details, installer experience, repair options, and building requirements rather than attributing every choice to cost alone.

What to check first

  • Ask how seams and wall terminations will be constructed.
  • Compare maintenance access and repair compatibility.
  • Review the written scope and manufacturer requirements for each proposed system.

Compare the roof and the repair, not just the label

  1. Identify the complete system

    Find out which membrane is present, whether it is coated, and what repairs have already been applied. These details determine the actual bonding surface.

  2. Compare the scope and limitations

    Ask what will be repaired, what underlying damage will be investigated, and what remains outside the proposed work. No single product corrects every roof defect.

  3. Check current instructions

    Use the published compatibility, preparation, application, and safety information for the selected product. Keep subsequent repairs in the same system; follow removal instructions before switching.

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.
