Stage 01 · Church roofs
From Horsham slabs to tiles and oak
Dunsfold's best-recorded roofs have changed covering more than once, which is a useful reminder that no roof stays as it was built.
The Victoria County History of 1911 describes the church of St Mary and All Saints as dating from between 1270 and 1290, built of Bargate stone rubble, with a timber bell-turret and a square spire covered with oak. It adds that the church was first roofed with Horsham slabs, and that by 1911 these remained only on the nave and north transept, most having been replaced with tiles. That is a compact story of roof change: stone to tile on the main roofs, wood on the spire, all on one building.
Why does a change of covering matter?
Each covering has its own weight, its own lowest safe pitch and its own way of being fixed, so swapping one for another is a design decision, not a like-for-like repair. A heavier covering, one that raises the roof's load by 15 per cent or more, brings building control into play, and the Planning Portal recommends an engineer's or surveyor's opinion beforehand. We raise that in any conversation about changing material, and the written price names exactly what is being fitted.
