The speaker expresses a preference for PVC roofing over EPDM flat roofs, citing issues with delamination and improper cutting/mending of EPDM sheets.
"It is not my choice for a roof. I like PVC primarily. There's some delaminations. First off, they use incorrect cuts of EPDM. Those should be single sheets and they mended several sections together because that's only 40 feet, let's say, at its biggest. And you can buy, you know, 100 foot rolls. So then you just cut each section properly, which means that they're just not cut properly."
