About our roof leak investigation in Anerley
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. Typical surveys look at leaks below a flat extension roof and damp underlay across a wide area, on flat roof details, the roof space and lead flashings.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. We look at what we are given access to in Anerley, inside and out. Let us know when the water shows, and in what kind of weather.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Prices for roof leak investigations in Anerley
To price your survey, we check:
- The package you choose: Basic, Standard or Premium
- Whether it’s a home or a commercial building
- The number of roofs, including extensions and garages
- How tall the building is and how easy the roof is to see
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
Helping us price your survey
A few details help us recommend the right survey and price. When you contact us, tell us:
- Anything about access we should know
- Where water is showing inside, if it is
- Any photos you have, taken from ground level or a window
- The style of property, from a terrace to a block
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or email us when you’re ready.

What else we do in Anerley
Anerley questions
Does a conservation area affect roof work in Anerley?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Anerley?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Can you find a leak when it isn’t raining?
Often, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it is useful, and it is included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
What will the report tell me?
Written findings with photographs, covering the condition of the leaking roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Do you look in the roof space?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Does the investigation include the repair?
The investigation is about finding the cause. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Why act early in Anerley
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. Any roof job in Anerley means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
Prices quoted always include VAT, and the written report is part of the package. Roof leak investigation starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

- Every finding written up with photos
- Thermal imaging and drone inspection where they help

Leaks and storm damage in Anerley
With Kingswood House about 1.3 miles north-west, Anerley sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. If your home in Anerley is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Each of these roof types has its own typical places for water to get in.
If you let a flat or house near Anerley station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you live near a park like Crystal Palace Dinosaurs, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls.

When you need someone else

- Defects hidden under coverings or inside walls without opening up
- The repair itself (the investigation finds and reports the cause)
- A structural engineer’s report
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer. What a survey covers and does not.

The survey, step by step
Every roof is different, but as a rough guide the survey takes about one to two hours at a typical home, and more on a big or complicated roof. If you have questions on the day, just ask. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.

Advice
Common roof problems in Anerley
Valleys carry a lot of water. Split linings, slipped valley tiles or debris can push water under the slates or tiles. The stain may appear well away from the valley itself.
Signs worth acting on include:
- Damp ceilings under a flat roof
- Water marks that spread in wet weather
- Damp on a chimney breast
- Damp underlay across a wide area
If you look after a shop, office or commercial unit, for example near Whitgift Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Before you book anyone
- Whether the price includes VAT
- Are they insured for the work?
- Whether you can ask questions once you have the report
- Will they check the loft as well as the outside?
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
