Don't panic! What you need to know about leaky roofs

It may sometimes feel as though it always rains in the UK, but autumn and winter bring additional challenges, such as cooler temperatures, which mean that nothing can quite get dry after a downpour. This combination of chill and damp means that roofs which are in less than tip-top condition may bear the brunt of the elements.

It may sometimes feel as though it always rains in the UK, but autumn and winter bring additional challenges, such as cooler temperatures, which mean that nothing can quite get dry after a downpour. This combination of chill and damp means that roofs which are in less than tip-top condition may bear the brunt of the elements.

It is extraordinary how you can have a leak that seems fine until a specific type of wind blows a specific type of rain in a specific direction, then an old leak that you thought had been resolved reappears like an unwelcome relative at Christmas, or – even worse – a new one puts in an appearance.

Unless you live in a mid or bottom floor flat, everyone is going to experience a leak at some point; in fact, for people accustomed to living in older houses, the drip of a roof leak into a bucket or pot may well be a familiar sound. If you detect a leak - new or reappearing - here’s what you need to do.

  1. Don’t panic! The first thing is to not panic and assess the situation. As long as everybody is safe and the leak isn’t causing a hazard by, for example, dripping straight onto a non-movable electrical appliance, things should be resolved.
  2. Damage limitation – once you have calmed yourself, it is time to start on the damage limitation. Place a bucket or any large receptacle under the leak. If it is night time and you are trying to sleep, a towel or cloth at the bottom of the bucket can reduce the noise of the dripping as well as preventing splashing onto the floor.
  3. Identify the source. If you have a water tank or piping in your attic and it is easily accessible, it may be worth popping your head up there to check the source of the leak; is it your roof, or maybe a burst pipe? If it is the latter, you may be able to stop the water flow by cutting your water supply.
  4. Look for the bulge! Quite a lot has happened before your leak appears to you. Water has collected in a spot and pooled to such a degree that the ceiling can’t contain it anymore. So there is likely to be a bulge, from which your water is dripping. You need to alleviate the pressure on that bulge or it could lead to serious damage – even your ceiling collapsing. Grab a knife, screwdriver or scalpel and cut the centre of that bulge, to allow water to flow freely from the ceiling without applying too much pressure.
  5. Call your local emergency roofer (or plumber if it is a plumbing issue). Check out our directory of trusted and rated traders to find one near you. They may be able to offer you immediate advice and will let you know when they can come out.

Find clear, practical answers to common roofing questions, helping homeowners understand everyday issues, know what checks they can carry out safely, and when it is best to contact a qualified professional.

  • How do I know if my roof needs repairing or replacing?

    A few broken tiles or a small patch of damaged flashing? That's usually a repair job. But if your roof is over 20 years old, leaks keep coming back in different spots, or you're seeing sagging or widespread cracking, replacement is probably the smarter long-term call. A proper inspection from a roofer will give you a straight answer before you commit to anything.

  • What are the signs of a leaking roof I shouldn't ignore?

    Water stains on ceilings, damp patches on walls, mould in the loft, or daylight peeking through the roof boards - all worth acting on quickly. A musty smell upstairs can also point to a slow leak, even when there's nothing visible. Roof leaks don't fix themselves, and the longer they're left, the more damage they do to insulation, timbers, and your ceilings.

  • Is moss on my roof a serious problem?

    Not an emergency, but don't leave it too long. Moss holds moisture against the tiles, which can work its way underneath and cause cracking in winter. It'll also block your gutters if it spreads far enough. Getting it professionally cleaned and treated is the way to go - it's not a job to DIY given the risks of working at height.

  • What happens if I delay getting my roof repaired?

    Small problems get expensive fast. A few displaced tiles can leave the felt underneath exposed to weather damage, and even a minor leak can cause timber rot, saturate insulation, and eventually ruin ceilings and walls. What could've been a straightforward repair becomes a much bigger project the longer you leave it, so it's best to get it sorted sooner rather than later.

  • How do I temporarily protect my home if my roof is damaged in a storm?

    If tiles are missing or water's getting in, the priority is limiting the damage until a roofer can get to you. A heavy-duty tarpaulin over the affected area is your best bet - make sure it extends well past the damage and is secured so it doesn't lift in the wind. Inside, move furniture out of the way, put buckets down, and use towels to manage any water coming through. Don't go up on the roof yourself as wet tiles are dangerously slippery.

  • What types of roofing materials are best for UK homes?

    Clay and concrete tiles, natural slate, and EPDM rubber for flat roofs are the most common on UK homes. Clay tiles are durable and handle our freeze-thaw winters well - though they're heavy, so not every roof can take them. Slate looks great and can last over a century done properly. For flat or low-pitched roofs, EPDM rubber has largely replaced traditional felt because it holds up much better against UV damage and standing water. The right call depends on your roof's pitch, your property's age, and what the structure can support.

  • How quickly can I get an emergency roof repair?

    Most roofers offer emergency callouts, but response times vary. In quieter periods, someone might get to you within a few hours. After a big storm when everyone's calling at once, you might be waiting a day or more. If there's a delay, get a tarpaulin over the damage in the meantime. One thing to watch: be wary of anyone who knocks on your door unsolicited after a storm offering to check your roof - it's a well-known scam.

  • What are green roofs and are they worth it?

    A green roof has a waterproof layer topped with soil and plants - usually sedums or grasses for a low-maintenance version, or something more garden-like if you want to go further. They insulate well, soak up rainwater, and are good for local wildlife. They can also extend the life of the waterproofing underneath by shielding it from sun and temperature swings. Whether it's worth it depends on your roof's structure and what you're hoping to get out of it. Installation needs to be done professionally - a leak underneath a green roof is a far bigger headache than on a standard flat roof.
