PVC roofing is waterproofing based on polyvinyl chloride, supplied as a membrane or sheet intended for that purpose. The material family includes product-specific arrangements. Its name alone does not determine the fixing, substrate or junction details required by the selected system.
Ask a proposal to identify the product used and its connection to existing building components. Meaningful comparison requires the same scope and starting points, not simply placing PVC against another material name. Retained layers also need an identifiable basis for assessment.
Product sheets can describe application conditions, but do not generally approve your roof. This explanation gives no installation procedure or automatic lifespan expectation. Retain information for the product actually selected alongside the assembly description and relevant handover documents for future reference.

No. Different material families exist. Identify the existing or proposed product.
