The Difference Between Pan & Cover vs Interlocking Roof Tiles

As someone who’s worked with clay roof tiles for many years, I’ve come to appreciate how much the right profile can transform not just the look of a roof but its overall performance too. When homeowners or architects ask about clay roof tile types, the conversation usually comes down to two classic styles — the traditional pan and cover (often called mission tiles) and the more modern interlocking tiles. Both are beautiful, durable, and made from the same high-quality clay, but they perform differently and create very distinct looks once installed.

Understanding Clay Roof Tile Types

When we talk about pan and cover tiles, we’re referring to a system that uses two pieces for each section of roof coverage. The “pan” is the lower, concave tile that catches water, while the “cover” is the curved upper piece that sits over the joints. This design has been used for centuries and is easily recognized on Mediterranean, Spanish, and colonial-style homes. I personally love the way these tiles add depth and rhythm to a roofline — the alternating curves create natural shadow lines that change with the light, giving the surface a warm, handcrafted feel. The open channels between each pan allow for good airflow under the roof, which can help regulate temperature and reduce moisture buildup in certain climates.

Interlocking tiles, on the other hand, are designed with precision edges that allow each tile to connect with the next like puzzle pieces. Instead of using separate pans and covers, these tiles have built-in overlaps that keep water out and resist wind uplift. They’re often preferred for modern homes because of their smooth, uniform appearance, but they’re also an excellent choice when installation speed and efficiency are important. Because they interlock, fewer tiles are needed per square metre, and installation can move more quickly compared to the traditional mission style. This design also provides strong protection in areas that experience heavy rain or wind, making interlocking clay tiles one of the most practical choices in today’s tile roofing market.

Choosing the Right Tile for Your Home

Choosing between pan and cover or interlocking tiles really comes down to your priorities — aesthetic versus performance, heritage charm versus modern precision. If you’re drawn to timeless European architecture and enjoy that handcrafted look, the mission tile system will give you exactly that. If you prefer a cleaner, more contemporary style with tighter seams and lower maintenance, interlocking clay tiles might be the better fit. Both offer the long-term benefits that make tile roofing such a smart investment: resistance to fire, exceptional durability, and colour that doesn’t fade over time.
