How to Tell If Your Roof Has Storm Damage

Why Storm Damage Is Easy to Miss Until It's a Serious Problem

A storm rolls through King's Lynn overnight, and by morning the street looks fine. But roofs absorb punishment that isn't visible from ground level, and damage left unchecked for even a few weeks can let water into the roof structure, soaking insulation and rotting timbers before you notice a single damp patch on the ceiling.

King's Lynn sits in a part of Norfolk that gets the full force of North Sea weather. Easterly winds in winter are particularly brutal, and properties on the edges of town — towards Castle Rising or out along the Fens near Sutton Bridge — have very little natural shelter. That makes post-storm inspections here more important than they would be in a sheltered inland town.

What to Look For From the Ground

You don't need to go near a ladder to carry out a useful first check. Stand back from your property and scan the roofline with binoculars if you have them. You're looking for anything that has shifted, cracked or gone missing entirely.

• Missing or lifted tiles: Clay and concrete plain tiles are common on the older terraced and semi-detached housing around the town centre and the estates built in the post-war decades. A gap in the pattern or a tile sitting at an odd angle is a clear sign of storm movement.
• Ridge tiles out of position: The mortar bedding on ridge tiles dries and cracks over time, and a strong gust can shift them. Look for gaps along the ridge or tiles that have slid to one side.
• Debris in gutters and on the ground: Granules from felt or mineral-surfaced flat roofing, lumps of mortar, pieces of lead flashing or fragments of tile are all worth noting. They tell you something has moved.
• Damaged or blocked gutters: High winds carry branches and other debris that crushes guttering or forces it away from the fascia. Sagging sections or gutters pulling away from the board indicate a problem. Our fascias, soffits and guttering service covers this as a separate repair if the roof itself is undamaged.
• Flashing lifted around chimneys or dormers: Lead flashing is vulnerable at the edges, and storm-force wind can peel it back from the upstand it's dressed into. Even a small gap in the flashing allows water into the roof space every time it rains.

Signs of Damage You'll Notice Inside the House

Water finds its way through the smallest breach. After a storm, check your loft space with a torch — ideally the morning after and again a few days later if it rains between then. Look for wet or discoloured insulation, water running down the rafters or joists, and any daylight visible between tiles.

Damp patches on ceilings, particularly near the chimney breast or in the corners of rooms on the top floor, are a strong indicator that water has entered the roof structure. By the time you see a stain on the plasterboard, the damage higher up is usually worse than it looks. Don't wait for it to dry out on its own — it won't, and the repair will be more involved than if you'd caught it early.

Specific Risks for King's Lynn Properties

Older properties in King's Lynn — including the Georgian and Victorian terraces around the Tuesday Market Place and the South Quay area — often have original chimney stacks that are mortared with lime mixes applied decades ago. These are vulnerable to wind and frost damage together. Spalling brickwork and cracked flaunching around chimney pots are common after a hard winter. We carry out chimney rebuilds where the stack has deteriorated too far for patching to hold long-term.

Flat roofs on extensions and garages are another weak point. Single-ply and felt systems can be lifted or punctured by wind-driven debris. A flat roof in King's Lynn typically costs between £70 and £120 per square metre to replace, depending on the membrane system used, so catching a small split early and having it repaired is considerably cheaper than waiting for a full failure.

When to Call a Roofer Rather Than Wait

If you've spotted missing tiles, lifted flashing or any sign of water ingress, don't wait for the next storm to confirm it's a problem. A professional inspection costs nothing with us and takes less than an hour. The National Federation of Roofing Contractors recommends having your roof inspected after any event where wind speeds exceed 50 mph — something that happens several times a year in coastal Norfolk.

You should also check whether your home insurance covers storm damage. Most policies do, but insurers typically require that the roof was in reasonable condition beforehand. A documented inspection report from a qualified roofer strengthens any claim you make.

If you've had storm damage to your roof repairs or are unsure what you're looking at, get in touch with us for a free roof survey in King's Lynn and the surrounding area. We cover the town and the villages across west Norfolk and can usually arrange a visit within a few days of your call.
