A mezzanine floor is an intermediate floor between the main floors of a building and is typically not counted among the overall floors. Roofing for a mezzanine refers to the overhead covering structure that protects the mezzanine from external elements or separates it from upper floors. Roofing can also mean the ceiling above the mezzanine when it’s inside a larger industrial or commercial building.
Mezzanine Floor Roofing Details
Roofing Material Options
Depending on use (industrial, commercial, storage), common materials include:
- Deck sheets + Concrete Slab (for heavy loads)
- Sandwich PUF Panels (insulated, lightweight)
- Galvanized Iron (GI) Sheets (durable, cost-effective)
- Polycarbonate Sheets (light transmission, aesthetic)
- Fiber-reinforced plastic (FRP) (chemical resistant)
- Aluminum Sheets (lightweight, corrosion resistant)
Supporting Structure
- Primary framing: Beams & columns (MS or steel)
- Secondary framing: Purlins, rafters
- Insulation Layer: (optional) for temperature or sound control
- Waterproofing layer: Bitumen sheets, membrane coatings
- Drainage: Gutter systems to prevent water stagnation.
Roofing Configuration Types
- Flat Roof – easier installation, but drainage must be perfect.
- Sloped/Pitched Roof – better for rainwater drainage.
- Skylight Integration – in warehouses/offices for natural light.
