Roofers in Southwick

Southwick was tiny before the railway. Adur District Council's appraisal records that in 1801 it had only 34 houses and a population of 271, rising to 957 in 1841, at about the time the South Coast Railway was built. The Victoria County History dates the railway across the parish to 1840, with a station opened for Southwick that year and a halt at Fishersgate in 1905. Almost everything that gives the place its present roofline arrived after that, so the roofs you see tell a story of Victorian growth, and each house carries its own age. Because the village grew in stages after the railway came, expect one street to hold roofs of several ages, with repairs made by several hands.

1.1 Terraces between the railway and the harbour

In the late 19th century most of the population lived in terraced houses between the railway and the harbour. Terraces mean shared walls, shared gutters and runs of chimney stacks, so a leak in one house can start in the next one's flashing. Sensible repair on a terrace means looking at both sides of the party wall. A neighbour whose work touches the shared junction deserves a conversation before scaffold goes up. Our roof repairs hub explains how a leak is traced to its source, usually by working back from the stain through the loft.

1.2 Villas north of the line

North of the railway, most housing of the period was larger Victorian houses and villas. Bigger houses mean bigger roofs, and bigger roofs have more junctions: valleys, the channels formed where two slopes meet, plus stacks, bays and dormers. Each junction relies on lead, and each is a place to check on a survey. A valley gutter that has worn through can run for years behind a ceiling before the stain shows, which is why we look in the loft as well as on the slope. Royston's brochure lists lead codes 4 to 8 for valley gutters, with heavier sheet for the more demanding positions, so the weight chosen should match the job.

1.3 What a survey shows on a Victorian roof

We photograph the covering, the lead, the ridge and the verge, and look into the loft where we can reach it, so the verdict comes from the roof as it stands rather than from its date. One written total follows. Where a few slipped tiles are the whole problem, that is what we tell you, and we do not talk a homeowner into more than the roof needs. If a re-roof is the right answer, you see the photographs before you decide, and you can take your time over the written price.

Southwick sits between Shoreham Harbour on the coast and the chalk downland of the South Downs. The Victoria County History notes housing estates built since the 1930s on the lower slopes of that downland. Houses from those first estates are now many decades old, and roofs of that age may still carry their original battens, underlay and ridge bedding. The condition of those layers, not the date alone, decides the work, and a ladder inspection finds it quickly. Shoreham Harbour lies on the coast side, and a roof near the shore takes gales, driving rain and salt air. We put no number to that exposure; we judge fixings and trim by their condition.

3.1 Ridges and verges on older estates

Where an older roof's ridge and hips are bedded on mortar by itself, they fall short of BS 5534 as revised in 2014, under which those tiles also receive a screw or clip. The verge, the rim of the roof running up a gable end, is treated the same way. Mortar fails slowly, and then a gale lifts the capping in one go. Refixing the ridge before that happens is a modest job beside the damage that follows a loose cap. Whenever tiles come up, we also examine the underlay and battens, since those layers date from the original build. If a roof is recovered, eaves ventilation matters: where a cold roof sits under high-resistance underlay, Marley's guidance is 25 mm along the eaves at a pitch of 15 degrees or less, and 10 mm where it is steeper.

3.2 Extensions and garages

Flat-roofed extensions and garages are common beside estates of this age, and the covering decides how long the roof lasts. Typical lives quoted for flat coverings are 20 to 30 years or more for EPDM (GreenSpec), 25 to 40 years for GRP and 10 to 20 years for torch-on felt (both Less, March 2026). They are typical ranges, never promises, and workmanship swings them. Our flat roofing hub explains the options. BS 6229:2025 sets a minimum finished fall of 1:80, and designers go steeper so the surface drains.
