Kenton Roof Leak Investigation
Roof leak investigations in Kenton from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and the South East.
- Drips from nail tips in a cold loft
- Water dripping from rafters or underlay
- Water marks that spread in wet weather
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Catch drips in a bucket and protect the floor
- Record whether it leaks in every downpour or only some
- Check whether pipes or tanks run near the stain
- Have an electrician check any wet fittings
If condensation is the cause, we explain it, and suggest how the loft space could be better ventilated. That avoids roof work that wouldn’t help.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.
About our roof leak investigation in Kenton
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof frequently turns out to be the source. Parapet walls and their gutters are looked at from wherever it’s safe. Our report shows what we found, with photos. If you are worried about condensation that looks like a leak and leaks at a dormer or roof window, we can find out what’s behind it.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, 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. We check what we’re given access to in Kenton, inside and out. It helps to know when the water appears and in what weather.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Wind, rain and roofs in Kenton
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Different coverings let water in at different points, which shapes where the search starts. Historic houses such as Headstone Manor, about 2.2 miles west, show how far back building in the area around Kenton 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.
For landlords with property near Kenton station, tracing a leak quickly matters when a tenant is living with it. Trees in and around Preston Park shed leaves that can end up in nearby gutters.

The survey, step by step
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes about 1–2 hours for a house, with bigger or more complicated roofs taking longer. In a London area like Kenton, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it is safe, the roof itself.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
How to prepare
- Show us where any leaks or stains appear
- Dig out any old roof reports or invoices
- Unlock side gates and any roof access doors
How to book
We survey roofs on weekdays, Saturdays and Sundays. To find a date that works for you, call 07833 053749 or drop us an email.

Questions from Kenton
Will parking be an issue for a roof survey in Kenton?
Sometimes, yes. If Kenton has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Is my home in Kenton 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.
How should I prepare for the leak investigation?
Clear the loft hatch so we can get into the loft space. Have any photos of the leak ready, plus details of past repairs. Keep catching drips and keep water away from electrics.
What will the report tell me?
Written findings with photos, explaining the condition of the leaking roof, any defects and our recommendations, by urgency where it matters. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it is useful, and it is included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
What happens after the survey?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you use drones?
Yes, where it applies and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where applicable, the Premium Survey.
How the survey changes by roof type
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
Signs you need a roof leak investigation in Kenton
Every flat roof covering has a working life. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
A survey can pick up problems such as:
- Water dripping from rafters or underlay
- Damp on a chimney breast
- Leaks below a flat extension roof
- Drips from nail tips in a cold loft
If you look after a building like St Gregory's Catholic Science College, a leak through a large roof is often found some distance from where the water shows inside.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How long they’ve been surveying roofs
- Whether VAT is in the quoted price
- When you’ll get the report
