Chapter one
Flint walls, gable ends and Holy Trinity's belfry
A flint nave with a stone belfry on its gable shows what village roofs ask of their edges: verges, flashings and the joins to masonry.
Holy Trinity, designed by W Donthorne in the Neo-Norman style, has a flint nave with no aisles, a stone belfry perched on the gable and a thin tiebeam roof, as the Sussex Parish Churches survey describes it. Whatever it is covered with today, a building of that shape shows where any roof starts to leak: along its edges and wherever it butts up against something else. The gable end is the stopping point of the slope. Wind pushes up beneath the verge there, the finished strip of tile or board along that edge, and rain gets driven into the gap. Add a stone belfry and a flint wall, and you have junctions between materials that swell, shrink and settle at different speeds.
At a glance
- Holy Trinity was designed in the Neo-Norman style
- Its nave is flint, with a stone gable belfry
- Roofs usually fail at edges and joins first
1.1 Lead where roof meets flint
The seal at such a junction is lead flashing, cut and dressed over the joint so that water is thrown clear. Flint gives it an awkward base, because the mortar lines wander between hard, uneven stones. We run a hand along the lead to find where it has lifted, then study the mortar that holds its upper edge. If that joint has crumbled, water slips behind the lead and travels down inside the wall, turning up as a damp patch far from the real fault. Lead is graded by code, and a higher number means thicker sheet: Code 4 is the common pick for general flashing, and Code 5 is thicker again. Our lead roofing page shows how a new flashing is cut and fixed.
1.2 What the loft gives away
Plenty can be read from inside before anyone climbs a ladder. Pinpricks of daylight near the verge, rusty nail tips poking through the underlay, a sheet pinned under the battens to catch wind-blown rain, and dark tide lines on a rafter all mark the route water has taken. Battens, the thin timber strips each course of tiles hangs from, are worth pressing with a screwdriver, because soft or split wood means long exposure. Everything we find goes into the survey photographs that sit with your written quote.
For an ordinary house, barn or outbuilding in the village, our roof repairs page explains how a fix is scoped before anything is priced, and why the smallest job that properly closes the leak is the one we recommend.
What people sayA leak at a gable end always means the tiles themselves have failed.
What is trueWater more often gets in at the verge, a flashing or a joint to a wall, then runs along the timbers before it shows inside.
