Tile roofs are among the most durable residential structures. When integrated with high-grade solar hardware, they provide a reliable, leak-free energy foundation for decades. Our SUS304/316 stainless-steel roof hooks are engineered to transfer structural loads directly to the rafters, ensuring that tiles remain decorative and protective, not load-bearing.
Pre-Installation Engineering Audit
Before deployment, verify the following technical parameters to ensure code compliance (JIS C8955 / AS/NZS 1170.2):
- Rafter Spacing: Confirm layout aligns with structural supports.
- Tile Profile: Ensure hook height and curvature match (e.g., flat tile vs. Roman tile).
- Hardware Integrity: Utilize self-tapping screws with sufficient embedment depth (min. 60mm into rafters).
Technical Workflow: 7-Step Installation
01 Secure Hooks to Structural Rafters
Identify the rafter location by temporarily lifting the tile. Slide the hook base into position directly over the rafter. Drive corrosion-resistant self-tapping screws through the pre-drilled base holes into the wood members. Verify full engagement to prevent pull-out failure under peak wind loads.
02 Splice Rails for Continuous Rigidity
Connect rail segments using internal or external rail connectors. Ensure splice joints are perfectly aligned and hardware is torqued to manufacturer specifications. A continuous rail distributes mechanical stress more evenly across the hook array.
03 Execute Hook-to-Rail Attachment
Fasten the spliced rails to the vertical arm of the tile hooks. Use a string line or laser level to check for lateral alignment. Precise rail leveling at this stage prevents module frame distortion and simplifies clamp installation later.
04 Primary Module Placement & End Clamping
Begin the first row from the roof's bottom edge. Align the module edge with the rail termination and lock it into place using End Clamps. Maintain a consistent overhang according to your engineering layout.
05 Secure Array with Inter-Module Mid Clamps
Insert Mid Clamps between adjacent modules. These dual-purpose fasteners lock modules to the rails while maintaining the necessary 10mm thermal expansion gap between frames.[1, 3]
06 Sequential Row Installation
Repeat the process row-by-row, moving from bottom-to-top and left-to-right. This workflow minimizes safety risks and ensures the array remains square to the roof ridge.
07 System Bonding & Electrical Grounding
Install grounding lugs on each rail and connect them to the system’s copper ground conductor. Proper bonding is essential for lightning protection and electrical code compliance (UL 2703).
Safety & Waterproofing Protocols
- Penetration Sealing: Apply high-quality solar-grade sealant to all screw penetrations. For flat tiles, utilize flashing kits where required.
- Load Bearing: Never apply weight to the tiles themselves. The hook must 'float' approximately 3-5mm above the lower tile to prevent cracking under snow loads.
- Final Torque Audit: Perform a visual check of all fasteners (torque marks recommended) before system commissioning.
