pantiles

Pantiles are a type of roof tile distinguished by an S-shaped curved profile that creates interlocking seams with neighboring tiles. They are typically made from clay or terracotta, and in modern construction also from concrete. The curved form allows efficient shedding of water and contributes to a relatively lightweight, economical roofing system.

Pantiles are long and slender; when laid, their profile forms a series of alternating crests and troughs along the roof. Common variants include clay pantiles, which retain a rounded contour, and interlocking pantiles, usually concrete, designed to lock to adjacent units for improved weather resistance and wind uplift performance.

Historically, pantiles originated in Europe and became widely used in the British Isles from the 17th to 19th centuries as a cost-effective roofing option suited to wet climates. They remain common in parts of the UK, Ireland, the Netherlands, and southern Europe, and have been exported to other regions as durable, economical tiles.

In installation, pantiles are laid over roof battens with a waterproof underlayment. They require a suitable roof pitch and proper ventilation to prevent moisture problems. Clay pantiles are appreciated for their natural weathered appearance, while concrete pantiles offer strength and color consistency. Replacement tiles are readily available, and damaged units can often be swapped without replacing nearby tiles.
