About our roof leak investigation in Roxeth
The aim is to find where the water is getting in and explain it. You get a photo-illustrated written report showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. Common reasons to book are water dripping from rafters or underlay and condensation that looks like a leak, across rooflights and dormers, valleys and parapet gutters and flat roof details.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Roxeth, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

What happens on the day
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes about 1–2 hours on an ordinary house, and about three to four hours for a commercial roof. From the street, a London terrace usually shows only its front slope or parapet, so in Roxeth we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Tell us who holds the keys.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- Mention any parking restrictions on your street
- If you are buying, check with the agent that we can get in

Why act early in Roxeth
Water and electrics don’t mix. Keep away from any fitting that water is reaching. Finding where the water is getting in should follow straight away. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. We confirm the price for your survey before booking.
What you get with us
- Professional indemnity and public liability insurance
- CAA-registered drone operator (Flyer ID and Operator ID)
- Independent findings on the roof’s condition
- A written report with photos

Useful tips for Roxeth property owners
From years of surveys, a few habits stand out:
- Leave roof access to professionals
- Note the weather when the leak shows
- Photograph the stain each time it appears
- Check the loft is accessible
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
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.
Roof by roof
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. If it’s too low, cracked or poorly dressed, water gets behind it.
Parapet and box gutters
A butterfly roof drains to a central valley gutter. Problems there often show in the rooms on the top floor.
Your questions about roof leak investigations in Roxeth
Is Roxeth in the area you cover?
Yes, Roxeth is one of the places we work. The survey and report are the same in Roxeth as anywhere else, and visits run on weekdays and weekends.
Is parking a problem for a survey in Roxeth?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you need to get into the loft?
If there is a loft and safe access to it, yes. The roof space can show things the outside can’t, such as damp timbers, staining or daylight.
How quickly is the report sent?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
How long will you be at the property?
It typically takes roughly 1–2 hours at most homes, and longer for a large or complex roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Can you trace a leak in dry weather?
In many cases, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.

What else we do in Roxeth
Do you need a roof leak investigation in Roxeth?
Valleys carry a lot of water. Split linings, slipped valley tiles or debris can push water under the slates or tiles. The stain may appear well away from the valley itself.
Signs worth acting on include:
- Ceiling stains that grow after rain
- Water that shows only in certain storms
- Damp patches next to the stack
- Damp underlay across a wide area
For site and facilities teams at buildings such as Roxeth Primary School, a leak through a large roof is frequently found some distance from where the water shows inside.

Leaks and storm damage in Roxeth
Historic houses such as Northolt Manor, about 1.9 miles south-west, show how far back building in the area around Roxeth goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. The covering and its details give the first clues when tracing where water is coming from.
Trees in and around Northwick Park shed leaves that can end up in nearby gutters. If you let a flat or house near Sudbury Hill Harrow station, a clear finding on where water gets in helps you brief a roofer right away.
