How a roof leak investigation works in Oval
We investigate roof leaks in Oval and across London and South East England. We visit on weekdays and at weekends. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. You get a photo-illustrated written report and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, and then call 07833 053749 or use the contact form. If you are worried about damp walls below an overflowing gutter and leaks at a dormer or roof window, a survey will tell you what’s going on.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Oval, 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.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the leaking roof, the defects we found and what we recommend.

FAQs for Oval
Is Oval in the area you cover?
Yes. We cover the whole of London and South East England, and Oval is part of that. Just call 07833 053749 or drop us an email and let us know about the property.
Is parking a problem for a survey in Oval?
Sometimes, yes. If Oval has controlled parking where you are, a visitor permit is the easiest answer.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and they go into the written report.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a pitched roof it frequently runs down a rafter before it finds a way through the ceiling. Following that route is what our investigation does.
Will you fly a drone over my roof?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
What do I do with the report?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
Useful tips for Oval property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Photograph the stain each time it appears
- Record whether it leaks in every downpour or only some
- Mention earlier attempts to fix the leak
- Protect furniture and flooring under the leak
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
Why get it checked now?
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. Tracing it now lets you plan the work rather than react to it. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 with VAT included. We can help you choose the package that fits what you want to find out.

What happens on the day
The visit normally starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. All told, expect about one to two hours, more where the leak is intermittent or the roof is large. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Oval runs like any other.
- You tell us where the water shows and when it appears.
- 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.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Jot down any questions you want answered
- Let us know about parking before the day
- For a flat or shared roof, check access with whoever owns or manages the building
Getting a price
A quick phone call is normally the easiest start: phone 07833 053749 or use the contact form and we will ask a few questions about the roof. You’ll have a price before anything is arranged.
Advice
Oval roofs and the weather
The wider area around Oval has a long history of building, with Buckingham Palace about 1.7 miles north-west. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. 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 Oval 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.
Trees in and around Vauxhall Park shed leaves that can end up in nearby gutters, and blocked gutters overflow and soak walls. For landlords with property near Vauxhall station, a clear finding on where water gets in helps you brief a roofer right away. If you look after a building like St Stephen's Church of England Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
