How Quickly Should a Leaking Roof Be Repaired After a Storm in Porthcawl?

Winter Storms Arrive in Sequence, Not Singly

Atlantic and Channel weather comes through in runs. A settled fortnight and then three systems in ten days is a normal winter pattern here, and each one arrives with nothing in front of the town to slow it down.

That changes the arithmetic of waiting. Inland, a damaged roof mostly deteriorates through water getting in. Here it deteriorates through being hit again, and a roof with an open edge is substantially more vulnerable the second time than it was the first.

Why an Open Edge Gets Worse Rather Than Staying the Same

Wind damages roofs by getting underneath the covering at an edge and working inwards. On an intact roof there are only a few such edges — the eaves, the verges or hips, the ridge — and they are detailed to resist it.

A gap creates a new edge in the middle of a slope, one that was never detailed to resist anything, with the exposed tail of the tile above it presented directly to the wind. The next storm does not have to be worse than the first to take considerably more.

On a hipped bungalow roof this matters most at the corners, where a hip meets the eaves, because that is where the airflow is most disturbed and the loading highest.

The Water Clock, Which Is Also Running

• Hours. Water reaching a light fitting, socket or consumer unit is an electrical problem first. Turn that circuit off at the board.
• A day. Insulation soaks and stops insulating, and on a bungalow there is a great deal of it across a large area, all directly above living space.
• Days. Plasterboard saturates and usually has to come out rather than dry out. A ceiling holding trapped water can come down.
• Weeks, repeated. Timber soaked and dried over and over is on a path towards rot, which is not a roofing repair.

There is a coastal addition: water driven in off the sea carries salt, which stays in plaster and masonry after the water has gone and draws moisture back out of the air. A wall repeatedly wetted this way can stay damp long after the leak is fixed.

So: How Quickly, Honestly

• Now. Water near electrics, a ceiling bulging, anything loose above a path or pavement, daylight through the roof, or a named storm forecast within days.
• Within days. An active leak, a gap with no underlay beneath it, loss of material at a hip or an eaves corner, or any damage with unsettled weather ahead.
• Within a couple of weeks. A gap over intact underlay, on a sheltered elevation, with settled weather forecast.
• Planned. Damp that is not growing and appears only in driven rain from one direction, with nothing loose.

Notice that the forecast appears in three of those four. That is not padding; on this coast it is genuinely the variable that moves things between categories.

If a Storm Is Coming Before Anybody Can Get to You

After a named storm every roofing company in the region has more calls than it can answer, so this situation is common rather than unlucky. What is worth doing:

• Ring and say specifically that there is more weather forecast. It affects the priority order, which is not fixed once set
• Ask whether a make-safe visit is possible even if the repair is not — securing an open edge is quicker than repairing it and it is what stops a small job becoming a large one
• Clear the ground below and keep it clear, and move cars
• Secure everything loose outside, including bins, furniture and trampolines
• Photograph the current state before the next storm, so you can show what it did

What is not worth doing is trying to cover it yourself. Sheeting fitted by somebody untrained becomes a sail in an onshore gale and regularly takes more of the roof with it than the original storm did.

If You Are Not There When It Happens

Common in a town with a large number of holiday homes, second homes and lets. The clock still runs, and it runs faster because nobody is watching it.

• Arrange for somebody to look after any named storm — a neighbour, a key-holder, a managing agent. A walk round the outside with a phone takes five minutes and it is the whole difference between a repair and a rebuild.
• Ask them to photograph the ground, not just the roof. Material on a path is the clearest evidence there is, and it gets tidied away.
• Get the loft checked after the first heavy rain following the storm, which is when damage shows.
• Give us a local contact when you call. We can attend, assess and send a written report with photographs to an owner anywhere.
• Check your policy on unoccupied periods, because cover commonly reduces after a set number of consecutive days empty.

The worst outcome is a property that takes damage in November and is opened up at Easter. Five months of an open roof in this weather is not the same problem five times over — it is a different problem entirely, and usually a structural one.

Why the Repair May Still Have to Wait

Even with the urgency understood, a permanent repair needs conditions. Mortar will not cure in the wet or cold, lead needs a dry surface to be dressed into, and flat-roof systems have moisture and temperature limits.

So the right sequence is often make it safe now, repair it properly in the next dry spell. That is not a delaying tactic. A repair done in the wrong conditions fails, and you pay for the access again when it does.
