What the money buys
A replacement roof is five purchases in one: access (scaffolding, £400 to £900 on a standard house, more for tall or awkward plots), strip and waste, underlay and battens (breathable membrane and treated timber as standard), the covering (concrete tile at the bottom, natural slate at the top), and the detailing (ridges, verges, valleys, leadwork, ventilation). A quote that shows all five lets you compare; a single line hides all five.
Material choices, priced
Concrete interlocking tile is the value default and suits most 20th-century stock. Reclaimed Welsh slate sits in the middle and keeps period roofs authentic, often cheaper than expected when sound original slates are reused. New Welsh slate is the premium century option. Spanish slate and fibre-cement alternatives split the difference, with quality questions worth asking specifically (quarry, warranty).
The building regs line
Re-roofing over half the roof triggers current insulation and ventilation standards. Compliance adds cost but it is not optional, and the quote should state how it is achieved. One that never mentions building regulations is telling you something about the rest of its numbers too.
How to compare two quotes
- Same scope? Strip versus over-clad, new underlay versus reuse, leadwork included or excluded.
- Same materials? Tile make and profile named, slate source named, membrane specified.
- Access visible? Scaffolding as its own line, priced for the actual plot.
- Guarantees? Workmanship in writing, manufacturer warranties named.
- Regs? Insulation and ventilation compliance stated.
