Roof Repairs Southport, which has handled more than 1,000 repairs across Southport, Sefton and West Lancashire, says the town’s reputation for foul weather is doing real damage, because it points people at rain.
Rain is not the problem. Crosby holds the closest long-running record to this stretch of coast, and its Met Office 1991-2020 average lands near 824mm annually, which is below Manchester’s and a long way short of Cumbria. On rainfall, Southport is thoroughly ordinary.
Its geography is not. Nothing higher than a dune stands between the town and the Irish Sea, so a depression tracking in off the Atlantic reaches the seafront at full strength, carrying a heavy load of salt with it. Merseyside sat under an amber wind warning for Storm Éowyn on 24 January 2025, which the Met Office ranked among the fiercest storms to hit these islands in over ten years. Storm Amy pushed gusts past 92mph across the north west last season.
“Salt does almost nothing to a slate,” said Dave of Roof Repairs Southport. “It is relentless on everything holding the slate on. We take roofs off in Birkdale and Ainsdale where the covering is in good order and the nails have simply rusted away underneath it. The same roof six miles inland at Ormskirk would have years left in it. People look up, see intact slates, assume they are fine. Then one gust off the estuary takes a row of them off in a night.”
The second local factor is one contractors from further inland rarely think to check for. A substantial dune system runs behind Southport, Birkdale, Ainsdale and Formby, and a steady westerly lifts fine grains off it and drops them a long way past the beach: into guttering, into the channels where two slopes meet, onto flat-roof drainage points. On its own it would wash through. Mixed with moss and leaf debris it sets into something closer to wet cement, and water then stands on the covering instead of running off it.
In a roof valley that gets worse, because backed-up water is forced under the slates on both pitches at the same time. According to the company, two ceilings staining in two separate rooms across one rainy fortnight is the classic signature, and it is regularly mistaken for two unrelated faults.
The season brings a warning with it as well. Cold-call roof inspections offered in the days after bad weather remain one of the longest-running doorstep frauds in the country, and Sefton gets a fresh round after every serious gale.
“Nobody legitimate finds your roof by knocking on your door the morning after you have experienced storm damage,” Dave said. “If someone tells you they have spotted damage from the pavement and can start today, that is the whole trick. Take the number, close the door, and ring somebody you chose yourself.”
Four things the company suggests homeowners check from ground level before the weather turns:
- Look at the edges rather than the middle of the roof. Wind does its damage by getting under a ridge, a hip, a verge or the first course above the gutter and lifting. The centre of a slope usually rides a storm out
- Watch the metalwork. On a coastal roof, rusting gutter brackets and flashings say more about how much life is left than the slates do.
- Within two miles of the front, clear gutters twice a year instead of the usual once.
- Give the seaward elevation the hardest look. West-facing pitches take the salt and the scouring, and they wear out years ahead of the sheltered side of the same house.
