5 Signs That Your Roof Is Leaking

Here we will pinpoint some of the more common signs that show your roof is leaking.

Water Stained Ceiling Caused By Leaking Roof

Water Stains On Your Ceiling

If you notice water staining on your ceiling there’s a big chance you have a roof leak. These stains can be very obvious if in the middle of your ceiling but a lot less obvious in the corners or alcoves of the ceiling, so it’s important to look in these areas regularly to check if staining has occurred.

Often this will be the first thing you notice if you have a leaking roof and the stains will look like brown spots that look like muddy puddles with rings around the edges of the stains. These stains are the mineral deposits that are left once the water has evaporated. 

Damp Staining On Walls

If you start to get damp staining on your walls this indicates you have mould or algae growing inside your walls. When water gets into your roof it can find its way into your internal wall cavities spreading damage as it seeps.

It’s essential that you pay attention to these stains as soon as you notice them as even a small stain could indicate a much larger problem behind the wall and up into your roof.

It’s important to look out for damp, mould and moss on your external walls too, as if damp is present it could indicate a continuous water leak. It could seep into your internal walls and start causing issues inside your home.

Ceilings That Are Sagging

If your ceiling is sagging this is because water is sitting on top of the ceiling and pooling. The weight of the water causes the ceiling to start to sag.

Eventually the ceiling won’t be able to withstand the weight of the water and the ceiling will collapse. This could cause a lot of damage to the contents of your home, including carpets, paintwork, furniture and electrical items.

Not to mention the damage to the collapsed ceiling! To minimise the damage a sagging ceiling can do to your home it’s very important to act as soon as you notice the ceiling is starting to sag. 

Missing Roof Tiles

If you notice you have missing or broken roof tiles anywhere on your roof, you are going to end up with a leak the next time it rains. Roof tiles are there to protect your roof from water entering your property and help the water drain off into your gutters where it is carried away.

If there are missing or damaged roof tiles, water will run down your roof into these gaps and cause water to accumulate in your attic and down into your interior walls and cause all kinds of havoc with the structure of your property.

After large storms it’s a good idea to inspect your garden for any fallen roof tiles, or climb up a ladder to inspect the roof if you can. Don’t ignore even one missing roof tile as it can cause thousands of pounds worth of damage to your home.

Damaged Or Raised Lead Flashings

Flashing is the material placed around things that come out of your roof, for instance chimneys and roof vents and around any corners or joints on your roof. Flashing is made up of impenetrable material that diverts water away from the seams that otherwise would allow water into your roof.

If this lead flashing is damaged or raised in any way it will allow rainwater to seep inside your walls and attic and cause catastrophic damage to your home with mould growth and also rot the wood in the structure of your roof causing irreparable damage.

Your flashing could become damaged in bad weather causing the material holding the flashing in place to deteriorate. ADI Leak Detection uses a range of roof leak detection testing equipment to help determine if damaged or raised lead flashing is to blame for your leaking roof. 


Yes, heading up to your loft is a great place to start when looking for the cause of a roof water leak. Take a torch with you as you’ll need good lighting and start to inspect the area for damp wood and mould growth.

You may even find dripping water or daylight coming through gaps in your roof. Another great way how to find a roof leak in your attic is to do the hosepipe test. Have someone stand in your attic and look out for water drops as you soak sections of your roof from the outside with a hosepipe. This will help pinpoint exactly where the water is entering your property. 

If you suddenly find yourself finding evidence of water leaking into your home and suspect it’s coming from the roof you may panic and think my roof is leaking, who do I call?

First of all it’s a good idea to call your insurance company to see where you stand in the way of cover, then it’s important to call a leak detection company like ADI Leak Detection who have specialist engineers located all over the UK to access the leak and find out where it is coming from quickly and effectively.

Remember the longer you leave the leak the more damage it will do to your home.

A roofer is a roofing specialist, not a leak detection specialist. A roofer can install a new roof, will provide roof replacement services and can fix common chimney and roof issues but may struggle to find the source of a water leak, particularly on a flat roof. Roof damage comes with age, as a roof ages its condition naturally deteriates.

Yes, blocked and overflowing gutters can be a cause of a roof leak. In bad weather, rain water should flow away from your roof and down the down pipes of your guttering system. Blocked gutters can overflow into your property causing damp and water damage. Blocked gutters are not normally the cause of a home emergency but are definitely a problem and potential cause of roof leaks.


One of the first things you may think is if my roof leaks, is it covered by home insurance? The good news is the answer is yes, as long as a few criteria are met. If your roof was in a good condition before it sprung a leak you are in luck. Your buildings insurance will cover any costs to repair it.

Also the roof leak needs to be the result of a storm or a fallen tree, something out of your control. If your insurance company deems that your roof already had damage due to general wear and tear or age related issues that you have not kept on top of they will not allow you to make a claim for repairs.

This is because it is your responsibility to keep your roof and property well maintained as the homeowner. Even if the damage and leak was due to very bad weather, if the condition of the roof was poor in the first place your insurance will not cover you.
