Barnehurst Roof Leak Investigation
Find out the condition of the leaking roof at your property in Barnehurst. Visits run on weekdays and weekends, in the daytime.
- Damp walls below an overflowing gutter
- Damp ceilings under a flat roof
- Damp patches next to the stack
What you can safely check yourself
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
How a roof leak investigation works in Barnehurst
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. If you’re worried about drips in the loft during heavy rain and wet patches high on an inside wall, a survey will tell you what’s going on, whatever the roof.
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 Barnehurst, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photograph where possible.

Roof leak investigations in Barnehurst: local notes
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in. Hall Place and Gardens, about 1 mile south-west, is one of the historic houses in the wider area around Barnehurst. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you look after a building such as Mayplace Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. Living close to Braeburn Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls. Take an older house close to Church of St Paulinus: leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

What we can’t see
Some things cannot be seen without opening up the roof, so a survey has limits:
- Leaks that only appear in weather we cannot recreate
- Faults hidden behind ceilings or boarding
- Whether rotten timbers meet design loads
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we will tell you. What a survey covers and does not.
What this survey covers
- Chimney stacks
- The roof space
- Flat roof details
- Slate and tile slopes
- Valleys and parapet gutters
- Lead flashings
- Rooflights and dormers
Leave it or get it looked at?
Guesswork repairs are a common reason leaks keep coming back. The real way in may be a metre or more away. An investigation finds the likely cause first. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.

FAQs for Barnehurst
Does a conservation area affect roof work in Barnehurst?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is parking a problem for a survey in Barnehurst?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when booking.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
How do I book a survey in Barnehurst?
It is easiest to call 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll take it from there. Surveys run seven days a week.
Is it a leak or condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
What does the report include?
It works through the roof part by part, in writing and with photos. Points are put with the most urgent first where relevant.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
How it works
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely. The survey usually takes between one and two hours for most homes, though a hard-to-trace leak can take longer. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Barnehurst runs like any other.
- 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.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before we arrive
- Clear the way to the loft hatch
- Keep pets out of the way during the survey
- Leave side gates unlocked

Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
Lead flashings
A leak at a flashing often shows some way from the joint. We check every flashing that could feed the stain.
Prices for roof leak investigations in Barnehurst

What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £150, including VAT.
