Roof leak investigations for homes and businesses in Thames Ditton
Most roof leaks start at a joint rather than the middle of a slope. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. Each one is looked at from wherever it is safe to see it. We’re often asked to look into damp patches next to the stack and leaks that appear only in driving rain, across chimney stacks, flat roof details and the roof space.
Around Thames Ditton, chimneys on older homes are a common source of leaks, through worn flaunching, failed pointing or lifted flashings. Damp on a chimney breast isn’t always rain from above, which is why it is worth tracing properly. It’s worth looking at the stack from outside and at the timbers beside it in the loft.
We keep jargon out of it: if work is needed, the report says so clearly.

Different roofs, different checks
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
After strong wind, take a look from the pavement or garden: 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.

What else we do in Thames Ditton
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe vantage point, photograph what we find and make notes for the report. Most visits take between one and two hours at a typical home, and more on a big or complicated roof. With a bit of garden around a house, as there frequently is around Thames Ditton, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.

- A visit is booked for a weekday, Saturday or Sunday.

Advice
Why act early in Thames Ditton
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Around Thames Ditton, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.

Thames Ditton roofs and the weather
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where water gets in depends a good deal on what the roof is made of and how it is detailed. With Hampton Court Palace about 1 mile north, Thames Ditton sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Living close to Giggs Hill Green is pleasant, but mature trees mean leaves in gutters and valleys each autumn. If you run a business near Bentall Centre, a quick answer on where water is coming in keeps a business running.

Your questions about roof leak investigations in Thames Ditton
Do you cover Thames Ditton?
We do. The survey and report are the same in Thames Ditton as anywhere else.
Will you come out to Thames Ditton?
Yes, Thames Ditton is on our map. A small place gets exactly the same survey as a big one.
Can you always find the source?
We cannot promise it. Water can travel a long way, and some leaks only show in particular storms. Where the source isn’t certain, we list the likely routes in order.
I live in a flat. Can you survey the roof?
Yes, if whoever owns or manages the building agrees access. We look at the parts we’re given access to, and the report makes that clear.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Is this an asbestos survey?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Do you need a roof leak investigation in Thames Ditton?
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the roof space.
We are often asked to look at:
- Water marks that spread in wet weather
- Water that shows only in certain storms
- Damp ceilings under a flat roof
- Drips in the loft during heavy rain
Anyone responsible for a site like Thames Ditton Junior School will know that tracing a leak on a big roof starts with where the water appears and works back.
