Installing solar panels on a tiled roof requires careful planning to ensure a secure and watertight mounting system. Since tile roofs are more delicate than metal or shingle roofs, the correct installation method helps prevent damage, leaks, or structural issues.
Steps for Attaching Solar Panels to a Tiled Roof
1. Assess the Roof Structure
Before installation, evaluate the roof’s condition and strength to confirm that it can support the weight of the solar panels. Important considerations include:
✔ Tile type (clay, concrete, slate, etc.)
✔ Roof pitch and orientation
✔ Structural integrity of rafters
2. Choose the Right Solar Mounting System
Using a high-quality solar mounting system is essential for securing the panels without damaging the tiles. SIC Solar offers durable and efficient tile roof mounting solutions designed to provide a stable foundation while maintaining the roof’s integrity.
Common mounting solutions for tiled roofs include:
- Tile Hooks – Installed under the tiles and attached to roof rafters for strong support.
- Tile Replacements – Specialized mounting tiles that replace existing tiles, avoiding breakage.
- Flashing and Waterproofing – Ensures a watertight seal around mounting points.
3. Remove and Install Roof Hooks or Brackets
- Carefully lift or remove specific tiles where the brackets will be attached.
- Secure stainless steel tile hooks to the roof rafters using screws.
- Ensure that the hooks sit flush and align properly for even panel placement.
4. Install the Mounting Rails
- Attach aluminum mounting rails to the installed brackets.
- Use leveling tools to ensure that the rails are straight for efficient panel placement.
- Double-check spacing and alignment according to the panel dimensions.
5. Attach the Solar Panels
- Secure the panels onto the mounting rails using mid-clamps and end-clamps.
- Ensure proper torque and fastening to withstand wind and weather conditions.
6. Electrical Wiring and Grounding
- Connect the solar panels to the inverter and electrical system.
- Properly ground the system to prevent electrical hazards.
- Perform a final inspection and testing before activating the system.
Key Considerations for Tiled Roof Solar Installation
✔ Use Non-Invasive Mounting Systems
Avoid excessive drilling into tiles to prevent leaks and damage. SIC Solar tile mounting systems offer customized brackets and hooks for a secure, non-intrusive installation.
✔ Ensure Proper Waterproofing
All mounting penetrations should be sealed with flashing and waterproof membranes to protect against leaks.
✔ Handle Tiles with Care
Tiles can be fragile, so walk cautiously on the roof and use proper lifting techniques to avoid breakage.
✔ Consider Roof Maintenance Access
Ensure the layout allows easy access for future roof maintenance or panel servicing.
