How long a PVC roof panel lasts depends mostly on thickness and UV protection. Thin, unprotected panels can yellow and turn brittle within a few years of full sun. Santiago ASA PVC sheets, 2.5 – 3.0 mm thick with an ASA top layer, are rated for more than 30 years, typically 25 – 30 years in normal use, with a 10-year warranty.
What shortens a panel's life?
- UV: breaks down unprotected PVC at the surface.
- Thin material: flexes and cracks at screws in wind.
- Over-tightened screws: crack the panel as it expands and contracts.
- Walking on the panel between supports.

How does the ASA layer help?
ASA holds its color under UV and shields the PVC core. Santiago rates color fastness at 30 years. Lighter colors also run cooler, which reduces thermal stress.
How to get the full life out of a roof
- Choose 2.5 mm or thicker; Santiago gives no warranty below 2.5 mm.
- Drill holes slightly larger than the screw shank so the sheet can move with temperature.
- Fix through the top of the rib, with sealing washers and caps.
- Walk only on purlins.
