Quiz: Which is more expensive — roof or facade?

Weekend quiz: 130 m² house, gable roof, facade with polystyrene and plaster. Which is more expensive to realize: the roof or the facade? Write down your answer. ## Solution: it is a draw... that is easy to lose ## Roof (130–150 m² of surface) - Construction (rafters, battens, membrane): £3,000–£5,000 - Ceramic tiles + flashings: £3,000–£6,000 - Roof windows 3 pcs: £800–£1,600 - Total: £7,000–£12,000 ## Facade (approx. 150 m²) - Polystyrene 15 cm + adhesive/mesh/anchors: £1,600–£2,400 - Silicone plaster: £1,200–£2,000 - Labor + scaffolding: £3,600–£6,000 - Total: £6,400–£10,400 ## Verdict The roof wins by a hair — but the real lesson from the quiz is different: these are the two most expensive stages of finishing the building shell, and it is easy to overpay for both (or cut costs too much). The difference between quotes for each of these stages can reach 20–30% — which is the equivalent of the entire roof windows. ## Bonus For both stages, the quality of the crew matters more than the cost of the material: a well-installed membrane and proper flashings protect against the costs of leaks.
