Roof Leak Investigation in West Hendon
Wondering about the leaking roof at a property in West Hendon? You can book a roof leak investigation in West Hendon and across Greater London, with plain-English findings.

Roof leak investigation in West Hendon: what you get
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. Common reasons to book are wet patches high on an inside wall and damp patches next to the stack, across chimney stacks, the roof space and rooflights and dormers.
Water getting into a London home often comes from a detail you cannot see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in West Hendon, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
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.

West Hendon: your questions answered
Do you cover West Hendon?
Yes. We cover the whole of London and South East England, and West Hendon is part of that. You can call 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Will parking be an issue for a roof survey in West Hendon?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention.
Can you trace a leak in dry weather?
Typically, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Why does not the damp patch line up with the hole?
Water follows the easiest path, not the shortest. On a pitched roof it frequently runs down a rafter before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
Before and after the survey
Nothing here needs a ladder. A few suggestions:
- Keep water away from lights and sockets
- Move stored items away from the hatch
- Note the weather when the leak shows
- Photograph the stain each time it appears
We email the report to you. It explains the likely entry point, the route the water takes and our recommendations. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Photograph anything new.
Leave it or get it looked at?
Water damage grows the longer it is left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. In West Hendon, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

How the survey works
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes about one to two hours for most homes, though a hard-to-trace leak can take longer. In West Hendon, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Outside, we check every likely route in.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- If you are buying, let the agent know when we’re coming
- Clear the way to the loft hatch
- Show us where any leaks or stains appear
How to book
Getting a price is simple: just call 07833 053749 or use the contact form and give us some details about the property and we will suggest the right survey. The price is agreed up front.
Advice
Do you need a roof leak investigation in West Hendon?
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the roof space.
These are some of the problems a survey can pick up:
- Wet patches on loft insulation
- Stains around a skylight
- Damp walls below an overflowing gutter
- Damp patches next to the stack
Anyone responsible for a site like The Hyde School will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Questions to ask before booking
- What exactly goes into their report
- What follow-up you get after the report
- Are they insured for the work?
- How long the report takes to arrive

It is useful to know what a survey won’t do before you book:
- The repair itself (the investigation finds and reports the cause)
- Leaks that only appear in weather we can’t recreate

Wind, rain and roofs in West Hendon
Outer London has plenty 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. Historic houses such as Heath House, about 3.2 miles south-east, show how far back building in the area around West Hendon goes. 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.
If yours is one of the older homes in the streets near St Matthias the Apostle church, old mortar, worn lead and slipped slates are the usual suspects when water gets in. Living close to West Hendon Playing Fields is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.
