Roof Leak Investigation in Kingston upon Thames
Tracing where water is getting into your roof in Kingston upon Thames. We have completed more than 5,000 surveys across London and South East England.
- Staining where a gutter or parapet meets the wall
- Drips from nail tips in a cold loft
- Damp patches next to the stack
Useful tips for Kingston upon Thames property owners
From years of surveys, a few habits stand out:
- Leave roof access to professionals
- Mention any plumbing above the damp area
- Mention earlier attempts to fix the leak
- Clear the loft hatch so we can get in
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that isn’t there.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
Roof leak investigations for homes and businesses in Kingston upon Thames
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt frequently lasts around 15 to 20 years, so age is part of the picture. We are frequently asked to look into damp underlay across a wide area and brown rings on upstairs ceilings, across valleys and parapet gutters, the roof space and rooflights and dormers.
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. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Kingston upon Thames, we inspect what we can reach safely and are given access to. It helps to know when the water appears and in what weather.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What affects the cost of roof leak investigations
The price reflects the time and kit the roof needs. That comes down to:
- Extra roofs, like extensions, dormers or garages
- House, block, shop or office
- How big the roof is
- Chimneys, valleys, parapets and other details
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400. You’ll know the price for your roof before booking.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- What made you get in touch
- Photos of the roof, taken safely from ground level or a window
- Access details, such as a loft hatch or a shared roof
- Your timetable, like an exchange date
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or email us to find out.
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. Most visits take an hour or two for most houses, though large, tall or awkward roofs take more time. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Preparing for the visit
- Have any paperwork from past roof work to hand
- Buyers: confirm access with the estate agent or seller
- For flats, make sure roof access has been agreed
Getting a price
A quick phone call is typically the easiest start: call 07833 053749 or email us and we’ll ask a few questions about the roof. The price is agreed before a date is set.

Kingston upon Thames: your questions answered
Is my home in Kingston upon Thames listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover Kingston upon Thames?
Yes, Kingston upon Thames is one of the places we work. The survey and report are the same in Kingston upon Thames as anywhere else.
Do you use thermal imaging to find leaks?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
How long does a roof leak investigation take?
The visit normally takes between one and two hours for a house, and longer for a large or complex roof. We’ll give you an idea of timing as you book.
Is the repair included in the leak investigation?
Our job here is to trace the leak and explain it, and the repair is separate. With the report, a roofer knows exactly where to look.
What should I do before you arrive?
Make sure the loft can be reached. Have any photos of the leak ready, and tell us about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.

Can I check my roof myself?
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.

A chimney stack has a good many places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. The damp may appear on a chimney breast, a ceiling or in the loft.
We’re often asked to look at:
- Water marks that spread in wet weather
- Water that shows only in certain storms

If you live in an older home near Church of St Luke, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
