A roof emergency is any fault that is letting in water now, threatening someone's safety, or likely to get much worse before a normal appointment can be arranged. That definition covers fewer situations than most people fear and more than some people hope. A missing tile on a dry afternoon is a job for this week. A ceiling that has started to sag under a pocket of water, a chimney stack leaning after a gale or a section of roof lifted off in a storm cannot wait. This guide gives you a way to sort what you are looking at, with the reasoning behind each call.
Three groups: emergency, urgent and plannable
Roofers and insurers use different words, but the practical split is the same. It rests on two questions: is anyone at risk, and is the house taking in water or losing its structure? If the answer to either is yes, you are in the first group. If neither is true but the fault will get worse with the next bout of weather, you are in the second. If the roof is simply tired, you are in the third.
| Situation | Group | What to do |
|---|---|---|
| Water running in, ceiling bulging or dripping near electrics | Emergency | Isolate the circuit, contain the water, call for help |
| Sagging roof line, cracked timbers or a leaning chimney stack | Emergency | Keep people out of the area and call for help |
| Large area of tiles or sheeting stripped by wind | Emergency | Photograph from the ground, call for a temporary cover |
| Tree or large branch lying on the roof | Emergency | Stay clear, call for help, tell the tree owner if it is not yours |
| A few slipped or cracked tiles, no leak yet | Urgent | Book a repair within days, before the next heavy rain |
| Loose ridge tiles or lifting flashing | Urgent | Book a repair; watch for wind-driven rain entry |
| Gutter pulled away or blocked valley | Urgent | Clear or re-fix before it overflows into the walls |
| Moss, worn pointing, ageing felt or faded tiles | Plannable | Survey, then repair or replace on your schedule |
The signs that make it an emergency
Water entering the building is the clearest trigger. A steady drip into a room is an emergency if it is heavy, near electrics or has already produced a bulge in the ceiling. A damp patch that appears after one very wet night and does not grow is urgent but less frantic. For a closer look at the dangers, our answer on whether a leaking roof is dangerous sets out what is and is not a risk to health and wiring.
Structural movement is the second trigger. A ridge line that has dipped, rafters that have visibly bowed, a chimney stack that has shifted or cracked at the base, or a ceiling that sags without any sign of water point to a load-bearing problem. These are not repairs for a weekend, and the room beneath should be left empty until someone has looked. If the building is, or may be, a danger to neighbours or passers-by, the local council's building control team has powers over dangerous structures. Our page on dangerous roofs and the council explains how that works.
Weather damage that has opened the roof is the third. High wind can lift a whole run of tiles, tear back a verge, peel sheeting from a garage or throw a trampoline, a fence panel or a branch through a slope. Even if no water is coming in at that moment, an open roof in a forecast of rain is an emergency in all but name. We cover this in more depth in storm damage to roofs.
Faults that are urgent but not an emergency
Most roof defects sit in the middle band. A few slipped tiles on an otherwise sound slope will let in water in some rain but not in others, depending on the wind direction. A ridge tile that has lost its mortar bed will sit loose until a gust finds it. A section of lead flashing that has lifted at the edge may be fine in a light shower and fail in a downpour. None of these justify waking a roofer at night, but all of them get worse, and each wet week adds to the repair.
The cost of delay in this group is usually damp timber rather than a dramatic event. Water that tracks along battens and rafters soaks insulation, stains ceilings and feeds rot in the ends of timbers that sit against a wall. Repairs that cost very little if done early can grow into a section of re-battening and a plasterer's bill if left over a winter. Our guide to finding and fixing a roof leak shows how a small fault grows.
The test we suggest is simple. Imagine the next heavy rain with a strong wind behind it. If that would put water in the house or make the fault bigger, book a repair now. If you cannot tell, a survey can: we photograph your own roof and show you what is loose, what is worn and what is fine.
What can wait, and what you should not do
Moss, algae, faded tiles and old, patchy pointing are signs of age, not emergencies. A roof can look rough and still keep water out for years. Treat these as planning items: have them looked at, price the options, and choose a time. The same goes for a shortfall in loft insulation, a worn but watertight flat roof, or a gutter that drips at a joint.
There is a trap in the opposite direction. People sometimes decide a problem is an emergency and do something dangerous about it. Going up on a wet roof, leaning a ladder against a gutter that is already weak, pulling at a loose tile from a window, or climbing into a loft with a torch to find a leak in the dark all lead to injuries. Our answer on whether to go on the roof to check damage explains why looking from the ground is the right default. The emergency is the roof, not a reason to risk your own safety.
Likewise, a sealant tube is rarely the answer to an urgent fault. Some products can slow a small seep, but they hide the real problem and can make a later repair harder. We look at this in do roof leak sealants work.
Special cases that catch people out
Flat roofs deserve their own caution. A flat roof that has ponded after rain is not an emergency in itself, but a membrane that has split or lifted at an edge can let a surprising amount of water into the deck, and a wet timber deck softens quickly. If the ceiling below an extension is stained, treat it as urgent and have it looked at before the deck is ruined.
Chimneys are another. A stack that is leaning, shedding bricks or has lost its pot should be treated as dangerous, because bricks fall onto paths, cars and neighbours. Keep the area underneath clear and call for help. If a cracked flue or a loose cowl is involved with a gas appliance, switch it off and get the appliance checked by a registered gas engineer, since that is outside roofing work.
Finally, there is the roof you share. On a terrace, a leak that starts next door may be yours by evening, and one that starts in your loft can reach theirs. Tell the neighbour early and photograph the boundary line. It makes any later repair conversation easier.
What to do in the first minutes
Whatever group you are in, the first steps are the same. Make people safe: keep everyone out of rooms with sagging ceilings and switch off the lighting circuit if water is near fittings. Contain the water with buckets and towels. Move valuables out of the way. Photograph the damage and the weather. Then call a roofer, and tell them what you can see rather than what you think it is.
The information that helps most is where in the house the water is showing, how long it has been going on, whether the weather is still wet, what the roof is made of, and whether you can get a clear photograph from the ground. With that, we can say whether it needs a temporary cover tonight or a visit when it is light. We prioritise emergency calls, and our aim is to make a leaking roof safe first and sort the permanent repair afterwards. Our note on out-of-hours roofing help explains what to expect when a fault happens in the evening or at a weekend.
Insurance, evidence and who pays
Many home insurance policies cover sudden storm damage and may not cover gradual wear. The wording differs between policies, so read yours and ring your insurer before work starts if you intend to claim. Insurers usually want evidence of the cause, so keep dated photographs of the damage, the weather and any temporary measures, and keep receipts. Emergency temporary repairs are often reimbursable under a claim, but the terms vary, and a policy may require the insurer to be told before major work begins. See our note on roof damage evidence for insurers.
If you rent, the picture changes. A roof leak in a tenancy is normally the landlord's responsibility to repair, though the process of getting it done is not always quick. Our short guide for a rented home with a leaking roof covers what to do and in what order. Emergency costs depend on the job and the time of day, so typical UK call-out figures of £150 to £350 before materials are only a guide. Your fixed quote follows the survey. For help on pricing, see how much an emergency roofer costs.
Calling us, and what happens next
If you are not sure which group you are in, send a few photographs by WhatsApp, or speak to us on 01256 213956. We will tell you plainly whether it needs attention straight away, and if it does not, we will say so rather than creating urgency. Where we attend, we make the roof safe first and then show you what we found, on photographs of your own roof, before suggesting a repair. Anything beyond a repair is explained with the reasons. You can read about the wider service on our emergency roof repairs in Basingstoke page.
