Chapter one
Holy Trinity, Horsham stone and who decides
The church on the ridge shows what a stone roof asks of anyone who works on it: the right slabs and the right permission.
Holy Trinity sits on the ridge where the old parish ended, and its tower goes back to the 13th century. A photograph taken about 1905 shows a roof of Horsham stone, which makes the church the village's best-documented example of a covering that belongs to this corner of the Weald. Each slab is a thick sandstone flag, graded by size so that big ones sit low and small ones high. The load is considerable, which is why the appraisal Horsham District Council wrote for Horsham itself speaks of steep pitches carried on strong timbers. When we look at a stone roof we begin in the roof space, checking rafters, purlins and ties before a single slab is judged.
At a glance
- Holy Trinity is Grade I, with a 13th-century tower
- A c.1905 photograph shows its Horsham stone roof
- Churches in use and listed houses follow different routes
1.1 Two consent routes in one village
Because Holy Trinity is Grade I and still a Church of England place of worship, changes to it are decided through a faculty, the Church's own permission system, instead of by the council. Its roofs have a record of change: the church was restored between 1843 and 1847, then again in 1887 to 1888, when J. P. St Aubyn installed tie-beam roofs and mended the tower. Houses follow another path. A listed house in Rudgwick needs listed building consent when repairs use materials that do not match, and the Horsham District Council planning team will confirm whether yours is listed.
1.2 Making the old slabs go further
The Stone Roofing Association asks owners to put their own slabs back before anything else, and to steer clear of slabs stripped from other buildings, since buying them can mean a historic roof elsewhere is being dismantled. A 2019 report described a shortage of new roofing slabs from the quarries. Our method follows from both points: we lift the slabs by hand, group them by size, rebuild the battens beneath (the slim timber strips that carry each course) and only then count what is missing. Anything we add is matched to what remains, and every course is photographed for you. More detail sits under Horsham stone roofing.
Who decides what, by type of Rudgwick building
| Building | Route for roof work | Who to ask |
|---|---|---|
| Holy Trinity, in use | The Church's faculty process | The parish and diocese |
| Listed house | Listed building consent for non-matching repairs | Horsham District Council |
| Unlisted house, conservation area | Matching repair usually needs no permission | Horsham District Council, before changing material |
