Roof Leak Investigation in Mortlake
Find out what’s going on with the leaking roof before you decide what to do next. We carry out roof leak investigations in Mortlake, with photographs and a clear written report.
- Water coming in around a roof light or dormer
- Water dripping from rafters or underlay
- Drips from nail tips in a cold loft
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes an hour or two for a house, or half a day or so for a commercial building. If you have questions on the day, just ask. In Mortlake, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- 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.
Before we arrive
- Move anything stored under the loft hatch
- Show us where any leaks or stains appear
- Keep pets inside or away from the areas we’re looking at

Advice
Roof leak investigations for homes and businesses in Mortlake
Our roof leak investigations cover Mortlake and the wider South East. We visit on any day of the week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then call 07833 053749 or send us an email. If you’re worried about ceiling stains that grow after rain and wet patches on loft insulation, we can find out what’s behind it, on flat roof details, the roof space and lead flashings alike.
In London, leaks often start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you are tracing a leak or recording storm damage in Mortlake, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Questions from Mortlake
Do you cover Mortlake?
Yes, Mortlake is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Will parking be an issue for a roof survey in Mortlake?
It can be, so it is useful to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
What happens next?
The report arrives by email, with photographs and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
How experienced are you?
Over 20 years and more than 5,000 surveys.
Does someone need to be in?
Not always. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
What should I do before you arrive?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
What we look for on each type of roof
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Valleys
Leaves and moss build up in valleys and hold water back. In heavy rain, it can spill under the edges of the slates or tiles.
Surveys for landlords and agents in Mortlake
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. Access is agreed with the tenant in advance.
When to book a survey in Mortlake
Blocked gutters can look like a roof leak. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
People usually book a survey when they’ve noticed something like this:
- Damp underlay across a wide area
- Staining where a gutter or parapet meets the wall
- Leaks at a dormer or roof window
- Leaks that appear only in driving rain
Take a building like Thomson House School: on a building that size, finding the source of a drip means looking well beyond the stain.
Questions to ask before you book
- Whether any drone flown is registered with the CAA
- What the survey will not cover
- What experience they bring
- Their insurance cover
Can I check my roof myself?
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
What happens if roof problems are left?
A leak rarely stays small. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
To find out what your survey will cost, phone 07833 053749 or send us an email and let us know about the roof. We’ll confirm the figure before booking.

Roof leak investigations in Mortlake: local notes
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. Where water gets in depends a good deal on what the roof is made of and how it is detailed. Historic houses such as Chiswick House, about 1.3 miles north, show how far back building in the area around Mortlake goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Mortlake station, tracing a leak quickly matters when a tenant is living with it. Living close to Palewell Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
