Roof leak investigations for homes and businesses in Long Ditton
Some ‘leaks’ are not leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, and the stains look much like a leak. Telling the two apart matters, since the cure for one will not solve the other. The pattern of the damp, the ventilation and the timing all help us decide. Common reasons to book are leaks that appear only in driving rain and leaks below a flat extension roof, on flat roof details, chimney stacks and slate and tile slopes.
In London, leaks frequently start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Long Ditton, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

The survey, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Surveys in Long Ditton can be booked for any day of the week. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it’s useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
How to prepare
- Let us know about parking before the day
- Check the loft hatch can be reached
- If it isn’t your property yet, arrange access through the agent

Why it’s worth a survey now in Long Ditton
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it is harder to clear. Finding the leak comes first. Any roof job in Long Ditton means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 with VAT included. We’ll tell you which package suits the questions you have.

Your questions about roof leak investigations in Long Ditton
Do you cover Long Ditton?
Yes. We survey roofs across London and South East England, and Long Ditton is part of that. You can call 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Long Ditton?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do I need to be at home?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we will agree the details when you book.
How many surveys have you done?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
Can you find a leak when it isn’t raining?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings usually point the way. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.
What will the report tell me?
A written report with photographs, covering the condition of the leaking roof, the defects we found and what we recommend, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
What we look for on each type of roof
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
When you need someone else
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Faults hidden behind ceilings or boarding
- Water from pipes, tanks or heating systems
- Putting the leak right

Long Ditton roofs and the weather
The wider area around Long Ditton has a long history of building, with Hampton Court Palace about 1.5 miles north-west. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Knowing the roof type helps narrow down where water may be getting in.
If you own a rental within reach of Surbiton station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Take an older house close to Church of St Mary: lead flashings, valleys and old chimneys are typical places for water to get in. Living close to Stokes Field is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
Long Ditton is about 1 mile south-west of Surbiton, in Greater London. From houses to flats and shops in Long Ditton, we can survey the roof on a weekday or at the weekend. Our area takes in places right across Greater London, large and small. We also survey roofs in London.

Tips that help
A little preparation and a few simple habits help. Some pointers:
- Mention any plumbing above the damp area
- Catch drips in a bucket and protect the floor
- Move stored items away from the hatch
- Don’t touch fittings that water is reaching
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention, so you know what to deal with first.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
