Solar Mounting Hardware Selection Starts with Roof Type
One of the most common mistakes in rooftop solar projects is selecting hardware before fully understanding roof conditions.
Different roof structures require different attachment methods.
Tile Roof Solar Mounting Hardware
Tile roofs typically require roof hooks installed beneath roofing tiles and attached directly to rafters.
Typical hardware includes:
- Stainless steel roof hooks
- Aluminum rails
- Mid clamps
- End clamps
- Grounding clips
Important considerations:
- Tile type
- Rafter location
- Wind load requirements
- Roof accessibility

Common solutions include:
- Trapezoidal roof hooks
- L feet systems
- Mini rail systems
Selection factors:
- Rib height
- Rib spacing
- Roof sheet thickness
- Structural load requirements
