Roof Leak Investigation in Ashburton
Roof leak investigations around Ashburton, with a written report you can act on. Weekday and weekend visits available.
- Water marks that spread in wet weather
- Condensation that looks like a leak
- Staining where a gutter or parapet meets the wall
How it works
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes roughly 1–2 hours at most homes, with bigger or more complicated roofs taking longer. Many London properties are flats or terraces with no 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, tell us when you book.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- 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.
Preparing for the visit
- Keep pets out of the way during the survey
- If you’re buying, check with the agent that we can get in
- Unlock side gates and any roof access doors

Our price is from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or send us an email with the details.
Advice
Roof leak investigations for homes and businesses in Ashburton
Some ‘leaks’ are not leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. Typical surveys look at drips from nail tips in a cold loft and wet patches on loft insulation, on valleys and parapet gutters, the roof space and lead flashings.
Water getting into a London home often comes from a detail you cannot 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 are tracing a leak or recording storm damage in Ashburton, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Ashburton questions
Is my home in Ashburton listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you cover Ashburton?
Yes. We work right across London and the South East, and Ashburton is part of that. Just call 07833 053749 or use the contact form and let us know about the property.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a pitched roof it often runs down a rafter before it shows. Tracing that path is the heart of a leak investigation.
Could my leak actually be condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We look at the pattern, take moisture readings and tell you which is more likely.
How long will you be at the property?
It typically takes about one to two hours for a house, though large, tall or awkward roofs take more time. Report times depend on the package.
What happens after the survey?
The report arrives by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or drop us an email.
What happens if roof problems are left?
Guesswork repairs are a common reason leaks keep coming back. The real way in may be a metre or more away. An investigation finds the likely cause first, so the repair is aimed at the right place. 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.
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 with VAT included. We can help you choose the package that fits what you want to find out.

Useful tips for Ashburton property owners
Most of what helps is simple and safe from the ground. A few suggestions:
- Check whether pipes or tanks run near the stain
- Clear the loft hatch so we can get in
- Tell us about any past repairs to the roof
- Write down the wind direction and rain when it leaks
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, rather than at the stain.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What a roof leak investigation looks like in Ashburton
In outer London, interwar semis with hipped, tiled roofs sit alongside older 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’s detailed. With Addington Palace about 2.4 miles south-east, Ashburton sits in an area with a long building history. 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.
Anyone responsible for a site like St Thomas Becket Catholic Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. If you run a business near Whitgift Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. Living close to Ashburton Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.
