Can all roofing membranes be heat welded?

No. Whether or not a roofing membrane can be heat welded depends on how the underside is finished. A roofing membrane can only be heat welded if the underside is finished with a film. Sometimes this film is perforated. The film will melt when exposed to heat and act as an adhesive. Always check whether the purchased roofing membrane can be heat welded.
