Tile Roof vs Metal Roof vs RC Roof: Which Is Best for Solar in Singapore?
Your roof type affects mounting, installation complexity, waterproofing, cost, and panel configuration. Here's what you need to know for each roof type.
Tile Roofs (Clay or Concrete)
Most common on homes built before 2000. Aluminium rail systems with roof hooks. Advantage: Optimal pitch angle, natural air gap for cooling. Cost: 5–10% more than RC flat roofs.
Metal Roofs (Standing Seam, Corrugated)
Common on GCBs. Standing seam allows tool-free, non-penetrating clamp-on mounts — zero waterproofing risk. Cost: Comparable to or less than tile.
RC (Reinforced Concrete) Flat Roofs
Modern homes. Ballasted mounting with concrete blocks — no penetrations. Advantage: Maximum flexibility, lowest cost. Note: Inter-row shading reduces installable area by 20–30% vs pitched roofs.
