Strand-on-the-Green Roof Leak Investigation
Tracing where water is getting into your roof in Strand-on-the-Green, using drones and thermal imaging where it applies. Get in touch for a price.
- Brown rings on upstairs ceilings
- Drips in the loft during heavy rain
- Water through the ceiling under a flat roof
Checking the roof from ground level
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
How a roof leak investigation works in Strand-on-the-Green
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. We survey lead flashings, flat roof details and the roof space, and common reasons people get in touch are condensation that looks like a leak and staining around the chimney inside.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Strand-on-the-Green, we inspect what we can reach safely and are given access to. It is useful to know when the water appears and in what weather.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

Strand-on-the-Green: your questions answered
Do you carry out roof surveys in Strand-on-the-Green?
Yes, Strand-on-the-Green is one of the places we work. The survey and report are the same in Strand-on-the-Green as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in Strand-on-the-Green is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Can you always find the source?
Not always, and we’ll be honest about that. Some leaks hide well, especially those that need wind-driven rain. Where the source is not certain, we list the likely routes in order.
How much is a survey?
Roof leak investigation starts from £150, including VAT. We confirm the price for the job before booking. To get a price, phone 07833 053749 or use the contact form.
How should I prepare for the leak investigation?
Make sure the loft can be reached. Have any photos of the leak ready, and tell us about past repairs. Keep catching drips and keep water away from electrics.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
Does someone need to be in?
Not necessarily. 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 we’re asked to look at in Strand-on-the-Green
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
It is worth booking a survey if you’ve seen:
- Wet patches high on an inside wall
- Water marks that spread in wet weather
- Stains around a skylight
- Damp ceilings under a flat roof
Anyone responsible for a site like Strand-on-the-Green Infant and Nursery School will know that on a building that size, finding the source of a drip means looking well beyond the stain.
Before you book any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Whether you can ask questions once you have the report
- What’s outside the scope of the survey
- Do they have a CAA Flyer ID and Operator ID for drone work?
Roof leak investigations in Strand-on-the-Green: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Different coverings let water in at different points, which shapes where the search starts. About 0.7 miles west lies Kew Palace, a reminder of how long the area around Strand-on-the-Green has been built on. 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.
For businesses in and around places such as Livat Hammersmith, finding where water is getting in quickly keeps disruption down. For an older house near a landmark like St Paul's Church, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Strand-on-the-Green is about 2 miles south of Acton, in Greater London. From houses to flats and shops in Strand-on-the-Green, the roof can be surveyed. Our Greater London coverage includes Strand-on-the-Green and the places around it. There is also a page for London.

Why act early in Strand-on-the-Green
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. 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.

Landlords, agents and block managers in Strand-on-the-Green
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Let us know about it when booking and we’ll plan the visit with that in mind.
We survey roofs for landlords and agents as well as homeowners. The report gives you a dated record of the leaking roof, with photographs, which helps you plan work between tenancies.
How it works
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes an hour or two, more where the leak is intermittent or the roof is large. In a London area like Strand-on-the-Green, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it is safe.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Keep pets inside or away from the areas we are looking at
- If you are buying, check with the agent that we can get in
- Have any paperwork from past roof work to hand
