Roof leak investigations for homes and businesses in Kennington
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. If you are worried about leaks below a flat extension roof and condensation that looks like a leak, 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 check what we’re given access to in Kennington, inside and out. It’s useful to know when the water appears and in what weather.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Roof leak investigations around Kennington
Historic houses such as Buckingham Palace, about 1.7 miles north-west, show how far back building in the area around Kennington goes. 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. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Knowing the roof type helps narrow down where water may be getting in.
If you own a rental within reach of Vauxhall station, tracing a leak quickly matters when a tenant is living with it. Anyone responsible for a site like St Stephen's Church of England Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain.

What this survey can’t tell you
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Water from pipes, tanks or heating systems
- Structural calculations (that is a structural engineer’s job)
- Defects hidden under coverings or inside walls without opening up
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you. What our survey covers.
What this survey covers
- Rooflights and dormers
- Valleys and parapet gutters
- The roof space
- Flat roof details
- Lead flashings
- Chimney stacks
- Slate and tile slopes
When to book a survey in Kennington
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
Typical things we are asked to look at include:
- Water through the ceiling under a flat roof
- Drips in the loft during heavy rain
- Water marks that spread in wet weather
- Damp underlay across a wide area
Living close to Vauxhall Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.
What to check before booking
- Whether you get a written report with photos
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What they will not be able to tell you
- How soon the report will arrive
FAQs for Kennington
Do you cover Kennington?
We do. Every survey there gets the same written report with photographs.
Will parking be an issue for a roof survey in Kennington?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Do you look in the roof space?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
How should I prepare for the leak investigation?
Clear the loft hatch so we can get into the loft space. Gather any photos and notes about when it leaks, and tell us about past repairs. Keep catching drips and keep water away from electrics.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
How the survey changes by roof type
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there is safe access.
Leave it or get it looked at?
Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. The sooner the cause is found, the less needs replacing. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.

Take a look at what a roof survey costs and two real surveys.
What affects the price in Kennington
The price reflects the time and kit the roof needs. That comes down to:
- Whether you choose the Basic, Standard or Premium Survey
- Commercial roofs and larger buildings
- The height of the building and how the roof can be seen safely
- Extra roofs, like extensions, dormers or garages
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 need to know.
Helping us price your survey
You do not need to know any roofing terms. It is enough to let us know:
- The address and postcode of the property
- The style of property, from a terrace to a block
- Photos of the roof, taken safely from the ground or a window
- When you need the report by
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or send us an email with the details.
The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes about one to two hours for most homes, though a hard-to-trace leak can take longer. For a visit in Kennington, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- You let us know where the water shows and when it appears.
- We check the stain, the ceiling and the loft above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Getting ready for the survey
- Point out any leaks or damp patches
- If the roof is shared, arrange access with whoever manages the building
- Check pets are kept safely away
