Roof Leak Detection in Sussex and Surrey
A roof leak is not always easy to find.
Water can enter through one part of a roof and travel beneath tiles, roofing materials, insulation or timbers before appearing somewhere completely different inside the property.
That means the visible damp patch is not necessarily where the roof is actually leaking.
Find My Roofer provides roof leak detection and roofing inspections across Sussex and Surrey, helping identify the likely source of water ingress and determine what needs to be repaired.
How Do You Know You Have a Roof Leak?
Some roof leaks are obvious, while others can remain hidden for some time.
Signs of a possible roof leak include:
- Water marks on ceilings
- Damp patches on walls
- Water appearing in the loft
- Damp or wet insulation
- Dripping during rainfall
- Mould or staining
- Damaged roof timbers
- A musty smell in the loft
- Water appearing around chimneys
- Damp around roof windows or junctions
Sometimes the first sign is simply a small stain that appears after heavy rain.
Even a relatively small leak is worth investigating before it causes more extensive damage.
Why Is My Roof Leaking?
There are many possible causes of a leaking roof.
These can include:
- Broken roof tiles
- Missing or slipped tiles
- Damaged slate
- Failed flashing
- Chimney problems
- Damaged valleys
- Failed roof junctions
- Deteriorated flat roofing
- Blocked drainage
- Damaged roof edges
- Storm damage
- Age-related deterioration
The cause can vary considerably depending on whether the property has a pitched roof, flat roof or another type of roofing system.
Finding the Source of a Roof Leak
Finding a leak is not always as simple as looking directly above the damp patch.
Rainwater can travel along roof timbers or beneath roofing materials before entering the property.
We therefore look at the wider roof area and consider potential entry points.
This can include checking:
- Roof coverings
- Tiles and slates
- Ridges and verges
- Valleys
- Flashing
- Chimneys
- Roof junctions
- Flat roof edges
- Drainage
- Areas where different roof sections meet
The aim is to identify the likely source before carrying out unnecessary repairs.
Roof Leak Detection for Pitched Roofs
Pitched roofs can develop leaks for many reasons.
A single cracked or slipped tile can allow water into the roof space, while damaged flashing or a problem around a chimney can allow water to enter during rainfall.
Valleys and roof junctions can also become problem areas.
Our Pitched Roofing service covers repairs and other work associated with pitched roofs.
Roof Leak Detection for Flat Roofs
Flat roof leaks can be particularly difficult to trace.
Water can move beneath the waterproof covering before eventually appearing inside the building.
Possible causes include:
- Damaged waterproofing
- Failed joints
- Deteriorated roofing materials
- Damaged flashing
- Problems around roof edges
- Poor drainage
- Water pooling
- Failed junctions
If your flat roof is leaking, see our Flat Roofing page for information about repairs and replacement.
Chimney and Flashing Leaks
Chimneys are common areas for water ingress.
Problems can develop with lead flashing, mortar joints, chimney coverings and the junction between the chimney and roof.
Water entering around a chimney can sometimes appear inside the property some distance from the actual entry point.
Our Chimney and Leadwork service covers roofing problems involving chimneys, flashing and leadwork.
Roof Leaks After Heavy Rain
Some roofs may only leak during prolonged or particularly heavy rainfall.
This can make the problem difficult to identify because the roof may appear dry during normal weather.
If you notice water entering after heavy rain, make a note of:
- Where the water appears
- How much rain there was
- Whether the leak only occurs during heavy rainfall
- Whether the problem has happened before
- Whether there are visible signs of damage
Photographs of the affected area can also be useful when initially discussing the problem.
Roof Leaks After Storm Damage
High winds and severe weather can create sudden roofing problems.
Tiles can become displaced, flashing can be damaged and other roof components can be affected.
If your roof starts leaking following a storm, it is important to address the problem promptly.
Where the situation is urgent, see our Emergency Roof Repairs service.
Can a Roof Leak Cause Structural Damage?
A long-term roof leak can allow moisture into areas that are not designed to remain wet.
Depending on the location and duration of the leak, water can affect:
- Roof timbers
- Insulation
- Ceilings
- Plaster
- Internal walls
- Decorative finishes
- Other parts of the building
This is why it is better to investigate a roof leak rather than repeatedly dealing with the visible damp patch inside the property.
Temporary Roof Repairs
Sometimes a roof requires immediate attention before a permanent repair can be completed.
For example, severe weather may leave part of a roof damaged and exposed to further rainfall.
Depending on the circumstances, temporary protection may be necessary while a permanent repair or replacement is arranged.
The appropriate response depends on the condition and accessibility of the roof.
Does a Roof Leak Mean I Need a New Roof?
No.
A leaking roof does not automatically mean that the entire roof needs replacing.
A localised problem such as a broken tile, failed flashing or isolated defect may be repairable.
However, if a roof has widespread deterioration, repeated leaks or extensive damage, replacement may be the more appropriate long-term option.
Our aim is to establish what is actually wrong before recommending the work required.

This can help us understand the problem before arranging the next step.
Our Approach to Roof Leak Detection
Our approach is based on finding the likely cause rather than simply treating the symptom.
We consider:
WHERE is the water appearing?
WHEN does the leak happen?
WHAT is above the affected area?
HOW could water be getting into the roof?
WHY has the problem developed?
WHAT repair or replacement work is actually required?
Once the likely cause has been identified, we can discuss the appropriate roofing solution.
Roofing Projects and Case Studies
Our Roofing Projects and Case Studies section will show examples of real roofing work.
As the project library develops, this will include examples of leaking roofs, repairs, replacement work and other roofing problems.
Photographs and project details can help demonstrate the type of problems that can occur and how they were resolved.
Frequently Asked Questions About Roof Leaks
1. HOW CAN I FIND WHERE MY ROOF IS LEAKING?
The visible damp patch inside the property may not be directly below the point where water enters. The roof and surrounding areas need to be assessed to identify the likely entry point.
2. WHY DOES MY ROOF ONLY LEAK WHEN IT RAINS HEAVILY?
Some roofing defects only allow significant amounts of water through during prolonged or heavy rainfall. The cause needs to be investigated rather than assuming the leak is coming from directly above the damp area.
3. DOES A LEAKING ROOF NEED REPLACING?
Not necessarily. Some leaks can be repaired. Replacement may be appropriate if the roof is extensively deteriorated or repeatedly failing.
4. CAN A BROKEN TILE CAUSE A ROOF LEAK?
Yes. A broken, cracked or displaced tile can allow rainwater into areas beneath the roof covering.
5. CAN CHIMNEYS CAUSE ROOF LEAKS?
Yes. Problems with flashing, mortar, chimney coverings or the roof-to-chimney junction can allow water into the property.
6. CAN FLAT ROOF LEAKS BE DIFFICULT TO FIND?
Yes. Water can travel beneath flat roofing materials before becoming visible inside the building.
7. WHAT SHOULD I DO IF MY ROOF STARTS LEAKING?
If it is safe to do so, protect belongings from water and contain any internal dripping. Avoid climbing onto the roof yourself. Contact a roofing professional to assess the problem.
8. DO YOU DEAL WITH STORM-DAMAGED ROOFS?
Yes. We can help with roofing problems caused by storms and severe weather.
9. DO YOU COVER ROOF LEAK DETECTION IN SUSSEX AND SURREY?
