Product Info

Material: Clay

Profile: Half round vent ridge tile (integrated ventilation opening)

Size class: Approx. 440-270-100

Finish: Reclaimed weathered surface with natural ageing and light lichen spotting

Colour: Traditional terracotta / red-orange clay with natural tonal variation and weathered patina

Condition: Structurally sound but cosmetically aged — surface weathering, minor edge wear and natural staining typical of reclaimed clay stock

Overall look & use:
This reclaimed terracotta half round vent ridge tile provides traditional ridge coverage with integrated roof space ventilation. The curved half round profile maintains a classic roofline appearance, while the built-in vent opening allows airflow into the roof void to help reduce condensation.

Its warm terracotta tone with natural ageing makes it particularly suitable for blending into established roofs and matching existing clay ridge systems on period, cottage and traditional properties.

It is particularly suited to:

Ridge ventilation upgrades
Roof repairs and maintenance
Matching existing terracotta clay ridge systems
Loft and roof space airflow improvements
Period, heritage and traditional roofing projects

Slating Headlap

Lap

Expandable Headlap Info

Choosing Headlap

Definition: The vertical overlap between successive rows of tiles to prevent water ingress.

Factors to consider:

Roof pitch: Shallower pitches (< 30°) need 75–100 mm; steeper (> 45°) can use 50 mm.
Climate & exposure: Wind-driven rain or heavy rainfall zones benefit from more headlap.
Tile profile: Deeper tiles may require extra overlap to seal correctly.

Rule of thumb:

Standard (30–45°): 50–75 mm
Low (< 30°): 75–100 mm
High (> 45°): 50 mm

Slate Size / Type

Slate 50mm Lap

Selecting Tile Size

Coverage per tile: Larger tiles cover more area but are heavier, affecting handling and substrate load.

Aesthetic scale: Big tiles suit modern, minimal lines on large roofs; smaller tiles give more texture and a traditional look.

Structural limits: Check rafters and battens can support the chosen tile’s weight and fixing centres.

Installation speed vs. waste: Larger tiles lay faster but may require more cutting at edges, increasing waste. Smaller tiles take longer but can reduce off-cuts.

Compatibility: Ensure the tile size works with your chosen headlap & side-lap for correct coverage per m².

By balancing pitch, weather, substrate capacity and appearance, you’ll pick the optimal tile size for performance and style.

Slates Per m2

Expandable Slates per m² Info

Calculating Slates per m²

Definition: Number of slates needed to cover one square metre.

Formula: 1 000 000 mm² ÷ (effective width × effective height)

Where:

Effective width = tile width – side lap
Effective height = tile height – head lap

Example: 610 mm × 355 mm tile, 20 mm side lap, 75 mm head lap:

Effective width: 610 − 20 = 590 mm
Effective height: 355 − 75 = 280 mm
Area per slate: 590 × 280 = 165 200 mm²
Slates per m²: 1 000 000 ÷ 165 200 ≈ 6.05

Adjust your headlap and sidelap values for precise coverage calculations.
