The biggest challenge when installing solar on tiled roofs is achieving a secure, waterproof mounting system without damaging tiles or compromising the roof’s integrity. Here’s why this is complex and how it’s addressed:
Key Challenges:
Tile Fragility & Removal:
Tiles (clay, concrete, slate) crack easily when walked on or drilled.
Installers must carefully remove/replace tiles at mounting points, increasing labor time and risk of breakage.
Waterproofing:
Every penetration (where mounts attach to the roof structure) is a potential leak point.
Requires meticulous flashing and sealing beneath the tile layer to redirect water—far more complex than asphalt shingle roofs.
Mounting System Complexity:
Specialized hardware (hooks, brackets, or rails) must anchor to the roof rafters beneath the tiles.
Tiles must be cut or notched to fit mounts, demanding precision to avoid gaps.
Labor Intensity:
Installation can take 2–3× longer than on composite shingle roofs due to tile handling.
Broken tiles need replacement (costly for historic or custom tiles).
Tile Variability:
Profiles (S-shape, flat, barrel) require different mounting approaches.
Weight limits vary: concrete tiles are heavier, stressing the roof structure.
How Overcome These:
Tile-Compatible Mounts: Use hooks/flashes designed for specific tile profiles.
Expert Crews: Experienced teams minimize breakage and ensure waterproofing.
Structural Assessment: Engineers verify the roof can handle added solar weight/wind uplift.
Sealant Protocols: Butyl tape, silicone, and metal flashing create redundant water barriers.
While challenging, solar on tiled roofs is highly reliable when done correctly—balancing aesthetics, durability, and energy savings.
When it comes to technical solar products such as roof hooks, price is important — but only in combination with performance.
For roof hooks, the main performance indicators are strength and watertightness. These features directly impact the overall system’s durability and cost-effectiveness. It is also important to consider how the roof hook connects to the roof structure. Poorly designed hooks can lead to leaks, instability, and extra costs.
That’s why our roof hooks deliver:
✔ Secure fit for various roof tiles and aluminum tile hook
✔ Corrosion-resistant stainless steel or aluminum
✔ Built for strength, lightweight, tested for safety
