Roof leak investigation in Hanworth, Greater London
A careful look at the leaking roof at your property in Hanworth, with photos and a written report.

What a roof leak investigation does not cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- An intermittent leak that shows no trace on the day
- Defects hidden under coverings or inside walls without opening up
- Whether rotten timbers meet design loads

Roof leak investigations for homes and businesses in Hanworth
Older homes have more places for water to get in. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. We check parapets, valleys and flashings from every safe vantage point. The findings are recorded with photos. Common reasons to book are water dripping from rafters or underlay and stains around a skylight, on chimney stacks, valleys and parapet gutters and slate and tile slopes.
Water getting into a London home often comes from a detail you can’t see from the street: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you’re tracing a leak or recording storm damage in Hanworth, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Useful tips for Hanworth property owners
There is plenty you can do without going near the roof. What helps most:
- Take dated photos of the leak
- Stay off ladders and the roof
- Check the loft is accessible
- Keep water away from lights and sockets
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. You can ask us about anything that isn’t clear.
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.
Do you need a roof leak investigation in Hanworth?
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Typical things we are asked to look at include:
- Damp underlay across a wide area
- Ceiling stains that grow after rain
- Damp on a chimney breast
- Leaks below a flat extension roof
Shop and office owners around Treaty Centre may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Questions to ask before you book
- Whether any drone flown is registered with the CAA
- What’s outside the scope of the survey
- What experience they bring
- When you will get the report

Prices for roof leak investigations in Hanworth
The price reflects the time and kit the roof needs. That comes down to:
- Which survey package you book
- Chimneys, valleys, parapets and other details
- Whether it is a home or a commercial building
- Roof area
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
Getting the details right at the start saves time. It’s useful to include:
- Pictures of the roof from a safe spot, if you have them
- Where the property is, with the postcode
- What’s prompted the survey
- Access details, like a loft hatch or a shared roof
Our phone lines are open seven days a week. For a price or to book, call 07833 053749 or email us.
What happens if roof problems are left?
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it is harder to clear. Finding the leak comes first. In Hanworth, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.
Why choose Independent Roof Survey in Hanworth

Hanworth roofs and the weather
The wider area around Hanworth has a long history of building, with Strawberry Hill House about 2 miles east. 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. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Different coverings let water in at different points, which shapes where the search starts.
For an older house near a landmark such as St Richard's Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. Landlords with a home close to Hampton station may find that a clear finding on where water gets in helps you brief a roofer right away.

What we do, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours, more where the leak is intermittent or the roof is large. You’re welcome to ask questions while we’re there. Surveys in Hanworth can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We look at the stain, the ceiling and the loft 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’s useful.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Check the loft hatch can be reached
- Jot down any questions you want answered
- Have any paperwork from past roof work to hand

Advice
Your questions about roof leak investigations in Hanworth
Can parking be tricky for a visit in Hanworth?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Does a conservation area affect roof work in Hanworth?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s included in our Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Do you use drones?
Yes, where it applies and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Will you check the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
