Roofers in Rose Green

Rose Green is in Aldwick parish today, and it lies within the old bounds of Pagham parish, which the Victoria County History says ran about five miles between the Bremere Rife and the Aldingbourne Rife. To the south lies Pagham Harbour, a tidal lagoon, and the same account records land being eaten away by the sea through the Middle Ages. That is history, not a rating. What it means for a roof is practical, and it starts at the edges, where wind finds a way under a covering first.

1.1 Reading wind exposure without a number

No two roofs see the same wind, and the manufacturers say as much. Wienerberger lists geographic location and altitude, together with local wind exposure, as inputs to a fixing specification, and Marley warns that a windward slope under 30 degrees can suffer severe suction. Flat ground with little cover is the sort of setting where those lines earn their place. So a survey here begins with how the roof is held down: whether each tile carries a mechanical fixing, whether the ridge and verge are fixed rather than only bedded, and whether anything has crept since the last gale. Close-up photographs cover each point, which leaves you able to check the verdict against what the roof looks like.

1.2 Ridge, hip and verge fixings

Along the crown of the roof runs the ridge. Along each outward corner where two slopes meet runs a hip, and at a gable end the roof stops at the verge. All three are capped, and all three catch the full force of a gale. The 2014 revision of BS 5534 stopped treating a mortar bed on its own as enough, so ridge and hip caps now also take a screw or clip. BS 8612:2018 covers dry-fix systems, which fasten the capping down with no mortar bed to crack. A roof with a wobbling ridge does not always need a new covering, because the ridge can often be lifted off and refixed the modern way. Our ridge tile repairs page sets out both methods.

Two listed structures stand close by: Nyetimber Windmill, Grade II since 15 January 1975, and Pagham's parish church of St Thomas a Becket, Grade I. The church is an Anglican building in regular use, so alterations to it go through the faculty system, with an exterior change still needing planning permission. Arun lists 29 conservation areas, and none is named for Rose Green or Pagham, while no Article 4 direction is recorded for Rose Green. An ordinary house here is not under those extra controls, though your own address and listing status decide what applies.

3.1 What no conservation area changes for a re-roof

Covering a roof again in matching material normally sits outside planning control altogether, as the Town and Country Planning Act exempts works that leave the external appearance unchanged; a listed building or a direction would alter that. Building control follows its own rules. The Planning Portal sets two limits: under 25 per cent of the total building envelope affected and under 50 per cent of the roof. Arun's own page takes a cautious line on re-roofing, so ask its team or a registered building control approver to confirm for your job; where a notification is needed, we deal with it. A heavier new covering, roughly 15 per cent heavier than the old, also brings building control in, and the Planning Portal advises a structural check before work starts. If you are considering roof windows, read our skylight planning permission guide first.

3.2 Insulation and ventilation under the new covering

Approved Document L (the 2021 edition until 24 March 2027, when the 2026 edition takes over) asks for an upgrade where more than 50 per cent of a roof's surface is renovated. Its Table 4.3 (Table 3.3 in the 2026 edition) sets 0.35 as the threshold for an existing roof and 0.16 W/(m²·K) as the improved figure, while a new or replacement roof element is limited to 0.15. A well-insulated roof still needs air to move. Marley says a cold roof under a high-resistance underlay needs a ventilation gap along the eaves: 25 mm for pitches of 15 degrees or less and 10 mm for steeper ones. That detail is easy to lose when a roof is re-covered, so we plan it before the first batten goes down. What the survey shows on this point decides what the written quote says.
