- Drips in the loft during heavy rain
The survey, step by step
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 roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. In Childs Hill, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it helps to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Move anything stored under the loft hatch
- Let us know about parking before the day
- Buyers: confirm access with the estate agent or seller
Getting a price
Booking is simple: just phone 07833 053749 or drop us an email, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.

Roof leak investigation in Childs Hill
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. Each one is looked at from wherever it is safe to see it. If you’ve noticed wet patches high on an inside wall and damp patches next to the stack, we can find out what’s behind it, whatever the roof.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. We check what we’re given access to in Childs Hill, inside and out. It helps to know when the water appears and in what weather.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to.

Roof leak investigations around Childs Hill
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Childs Hill is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Knowing the roof type helps narrow down where water may be getting in. Heath House, about 0.7 miles east, is one of the historic houses in the wider area around Childs Hill. Older homes in the wider area frequently have features worth a closer look, like 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.
Take a building like All Saints' CofE Primary School NW2: a leak through a large roof is often found some distance from where the water shows inside. If you live near a park such as Childs Hill Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.

Questions from Childs Hill
Is Childs Hill in the area you cover?
We do. Every survey there gets the same written report with photographs.
How do I find out if my home in Childs Hill is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Can you trace a leak in dry weather?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
What will the report tell me?
You get our findings in writing, part by part, with photos. Points are put with the most urgent first where relevant.
Will you fly a drone over my roof?
Yes, where applicable and safe. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
How long will you be at the property?
On site, it usually takes about 1–2 hours, more where the leak is intermittent or the roof is large. Report times depend on the package.
Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Have an electrician check any wet fittings
- Check whether pipes or tanks run near the stain
- Mention earlier attempts to fix the leak
- Note the weather when the leak shows
We email the report to you. It sets out where we believe the water is getting in, how it is travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Keep the loft space ventilated. Air movement keeps condensation down, which is frequently mistaken for a leak. Keep insulation clear of the eaves.
Leave it or get it looked at?
Wet insulation does not insulate well. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there’s time to plan.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

When to book a survey in Childs Hill
Every flat roof covering has a working life. A felt roof often lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Leaks often start at the edges, upstands and outlets.
People normally book a survey when they’ve noticed one of these:
- Ceiling stains that grow after rain
- Wet patches high on an inside wall
- Damp on a chimney breast
- Damp underlay across a wide area
Landlords with a home close to Cricklewood station may find that a clear finding on where water gets in helps you brief a roofer straight away.
What to check before booking
- What experience they bring
- Which parts of the roof they’ll actually see
- Whether any drone flown is registered with the CAA
- What happens after the report arrives
