Yes, FRP (Fiberglass Reinforced Plastic) roofing panels typically require a specific type of underlayment. This underlayment acts as a barrier between the panels and the roof structure, providing additional insulation, moisture resistance, and protection against potential leaks. The specific type of underlayment required may vary depending on factors such as the climate, building codes, and manufacturer recommendations, so it is essential to consult the manufacturer or a roofing professional for the best underlayment choice for FRP roofing panels.
