Roof leak investigations for homes and businesses in Ham
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. We survey lead flashings, valleys and parapet gutters and flat roof details, and common reasons people get in touch are ceiling stains that grow after rain and drips in the loft during heavy rain.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. We check what we’re given access to in Ham, inside and out. It helps to know when the water appears and in what weather.
What you get is a clear record of the leaking roof on the day we saw it. It is useful straight away, and a good reference for later, such as when you want to compare after future work.

What a roof leak investigation doesn’t cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- A structural engineer’s report
- Plumbing leaks that look like roof leaks
- Leaks that only appear in weather we can’t recreate
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey before you book. What a survey covers and does not.
Roof types and parts we check
- Chimney stacks
- Lead flashings
- Slate and tile slopes
- The roof space
- Flat roof details
- Rooflights and dormers
- Valleys and parapet gutters
How the survey works
When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can safely be seen, from ground level, from windows, in the loft space and by drone where it applies. Most surveys take roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. In Ham, as in much of London, lots of properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know as you book.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- 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.
How to prepare
- Unlock side gates and any roof access doors
- Keep pets inside or away from the areas we’re looking at
- Make a note of anything you’d like us to look at
How to book
Our price is from £150, including VAT. The exact figure depends on the roof and the package, so call 07833 053749 or use the contact form with the details.

Ham roofs and the weather
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. The covering and its details give the first clues when tracing where water is coming from. About 0.6 miles north lies Ham House, a reminder of how long the area around Ham has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof.
For landlords with property near Teddington station, a clear finding on where water gets in helps you brief a roofer straight away. Take a building like Meadlands Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you look after a shop, office or commercial unit, for example near Bentall Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Ham is about 1 mile south-east of Twickenham, in Greater London. We visit Ham as part of our work across Greater London. We cover towns and villages across Greater London, from the larger towns to small villages. Our London page covers surveys nearby.
Surveys in TW10, KT2 and TW11 are booked the same way as anywhere else. Whether your property is on New Road, Lock Road and Cave Road or a nearby road, we can survey it. Ham sits on or near the A307, which makes travel easy. If you’re just outside Ham, we cover Petersham (1 mile north), Eel Pie Island (1 mile north-west), Strawberry Hill (1 mile west), Teddington (1 mile south-west) and Richmond (1 mile north). Further out, we also cover London (10 miles north-east), City of Westminster (9 miles north-east), Marylebone (9 miles north-east), Kensington (6 miles north-east), St Pancras (10 miles north-east) and Shoreditch (12 miles north-east).
Near you in Ham
We work in homes and buildings around Grey Court School, The New Inn Public House and Sudbrook Park. Ham’s nearest station is Teddington station, roughly 1.2 miles south-west of the centre. A little further out are Eel Pie Island Museum (1.1 miles north-west) and Bentall Centre (1.6 miles south). Open spaces near Ham include Kew Gardens Lake and Richmond Hill.
Why it’s worth a survey now in Ham
Patching the spot above the stain frequently does not work. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.

Different roofs, different checks
Parapet and box gutters
Linings, joints and outlets are inspected wherever it’s safe.
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.

What else we do in Ham
Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Clear the loft hatch so we can get in
- Catch drips in a bucket and protect the floor
- Write down the wind direction and rain when it leaks
- Stay off ladders and the roof
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Keep gutters, valleys and outlets clear, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.
Letting agents can arrange access with tenants. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Ham: your questions answered
Will parking be an issue for a roof survey in Ham?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Do you carry out roof surveys in Ham?
Yes, Ham is one of the places we work. Every survey there gets the same written report with photographs.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
What happens after the survey?
The report arrives by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Can you survey at the weekend?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
