What Influences Roof Truss Prices?

The cost per square metre can vary significantly depending on several factors:

• Timber Type – SA Pine is most common, but alternative timbers can cost more.
• Roof Design – Simple gable roofs are cheaper than complex hip or custom roofs.
• Span & Pitch – Larger spans and steeper pitches require more material.
• Roof Covering – Tile roofs are heavier and require stronger trusses than metal sheeting.
• Location & Transport – Delivery distance impacts the final price.
