Well Hill Roof Leak Investigation

- Ceiling stains that grow after rain
- Condensation that looks like a leak
Roof leak investigation in Well Hill: what you get
Not every drip is a leak. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Knowing which it is means the right fix can be done, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. If you are worried about leaks below a flat extension roof and staining where a gutter or parapet meets the wall, we can find out what’s behind it.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. We look at what we are given access to in Well Hill, inside and out. It is useful to know when the water appears and in what weather.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Surveys for landlords and agents in Well Hill
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Letting agents frequently book on a landlord’s behalf. Access is agreed with the tenant beforehand.
Prices for roof leak investigations in Well Hill
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- The number of roofs, including extensions and garages
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
- Roof area
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.
Getting in touch
When you call or email, these details help:
- When you need the report by
- Access details, such as a loft hatch or a shared roof
- What made you get in touch

Every survey is priced before it is booked, so you know the cost up front. Our price is from £150, including VAT. For a price for your roof, call 07833 053749 or send us an email.
Why act early in Well Hill
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it is harder to clear. Stopping the water is the first step. In Well Hill, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
Prices start from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.

What a roof leak investigation does not cover
Before you book, it is worth knowing what a survey won’t do:
- Whether rotten timbers meet design loads
- A promise to find every leak on a single visit
- The repair itself (the investigation finds and reports the cause)

Well Hill questions
Is my home in Well Hill listed or in a conservation area?
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. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out roof surveys in Well Hill?
We do. The survey and report are the same in Well Hill as anywhere else, and visits run on weekdays and weekends.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Why isn’t the leak directly above the stain?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is often well away from the mark. That’s why we trace the route rather than patching above the stain.
Does the investigation include the repair?
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, which whoever carries out the work can follow.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Can thermal imaging help find my roof leak?
We use thermal imaging where it helps, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
What we look for on each type of roof
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. One slipped slate can be enough to cause a leak.
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
What happens on the day
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when booking.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Have any paperwork from past roof work to hand
- Let us know about parking near the property
- Make a note of anything you’d like us to look at
How to book
Booking is simple: just ring 07833 053749 or drop us an email and give us a few details about the property and we’ll explain which survey suits. The price is agreed up front.

Roof leak investigations in Well Hill: local notes
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Well Hill is one of them, bay roofs, hips and later dormers each have their own details. The covering and its details give the first clues when tracing where water is coming from. With Lullingstone Castle about 2 miles east, Well Hill sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Trees in and around Hewitt's Chalk Bank shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. If you own a rental within reach of Knockholt station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. For site and facilities teams at buildings such as Chelsfield Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.
