PVC is what belongs over a Frisco restaurant kitchen or any building discharging grease and oils onto the roof, because it handles the chemical exposure that degrades other membranes. If a TPO roof over a kitchen is failing early, that is usually the reason.
PVC Roofing Across Frisco
Frisco's growth means a lot of homes are on their original roof and their owners have never been through an insurance claim. That is where most of the confusion sits: what counts as storm damage, what an adjuster is looking for, and how long the process takes. Newer roofs are not immune either. Hail does not care how old a shingle is, and bruising on a five-year-old roof still shortens its life.
Where PVC Beats TPO
PVC handles grease, oils and chemical exposure that degrade other membranes, which is why it is the usual specification over restaurant kitchens and any building with significant exhaust discharge onto the roof.
Welded Seams
Like TPO, PVC is hot-air welded into a continuous sheet. A correctly welded seam is as strong as the membrane; a poorly welded one is the failure point for the life of the roof.
Fire And Wind
PVC is inherently flame-retardant and achieves strong wind uplift ratings when the attachment is specified properly for the deck.
Service Life
Twenty to thirty years is realistic on a properly detailed installation, with the details, not the field, deciding where it lands in that range.
