Roof leak investigation in Westerham
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey lead flashings, valleys and parapet gutters and rooflights and dormers, and the problems we are asked to look at most are damp ceilings under a flat roof and condensation that looks like a leak.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers normally exclude wear and tear. That’s as true in Westerham as anywhere in London. A written record with photos helps you explain what was found to whoever deals with it next.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

FAQs for Westerham
Will parking be an issue for a roof survey in Westerham?
It depends on the street. If Westerham has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in Westerham is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is 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.
Is it a leak or condensation?
It’s a common question. A leak typically shows in one area and follows rain, while condensation is frequently spread out and worse in cold weather. The report explains which it looks like and what to do.
Will you walk on the roof?
Only when it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Is this an asbestos survey?
No. Asbestos surveys and testing aren’t part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with the freeholder or managing agent. Mention it when you get in touch and we will plan the survey around it.
What happens after the survey?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.

Common roof problems in Westerham
Condensation is often mistaken for a leak. Warm, moist air from the house rises into a cold roof space and condenses, particularly in lofts with blocked eaves. Wet nail tips and damp underlay over a wide area are classic signs.
Typical things we’re asked to look at include:
- Water that shows only in certain storms
- Water coming in around a roof light or dormer
- Damp on a chimney breast
- Staining where a gutter or parapet meets the wall
Take an older house close to Church of St Mary the Virgin: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Questions to ask before booking
- How they plan to inspect the roof safely
- What they will not be able to tell you
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How long the report takes to arrive
Useful tips for Westerham property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Don’t climb onto the roof to look
- Let us know what has already been tried
- Do not touch fittings that water is reaching
- Note the weather when the leak shows
The report gives whoever carries out the work a clear starting point. The photos show the defects and where they are, so the repair is aimed at the cause.
Keep gutters, valleys and outlets clear, particularly in autumn. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
How the survey works
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. Most visits take about one to two hours for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so a visit in Westerham moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- From the roof space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Point out any leaks or damp patches
- Tell us about parking before the day
- If the roof is shared, arrange access with whoever manages the building

Why get it checked now?
Lingering damp encourages mould on ceilings and walls. It’s unpleasant, and it is harder to deal with once established. Finding the leak comes first. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Every price we give includes VAT, and the written report is part of the package. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Roof leak investigations around Westerham
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Different coverings let water in at different points, which shapes where the search starts. Quebec House, about 0.2 miles south-east, is one of the historic houses in the wider area around Westerham. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
Landlords with a home close to Hurst Green station may find that a clear finding on where water gets in helps you brief a roofer right away. Westerham is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier.
