Questions from Ashburton
Does a conservation area affect roof work in Ashburton?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can parking be tricky for a visit in Ashburton?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
How do I arrange electronic leak detection in Ashburton?
It is easiest to phone 07833 053749 or email us. Give us the address and a few details about the roof, and we’ll recommend the right survey. We survey on weekdays and at weekends.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
What do I do with the report?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you survey on Saturdays and Sundays?
We carry out surveys on any day of the week. To find a day that suits you, ring 07833 053749 or email us.
About our electronic leak detection in Ashburton
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We’ll tell you if we think the leak is coming from somewhere else. It won’t show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. We survey roof terraces and balconies, commercial flat roofs and flat roof membranes, and people most often book us about holes left by work on the roof and repairs that haven’t stopped the leak.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Ashburton, the flat roof is often a shared part of the building.
Nothing in the report is left vague: where something needs attention, it says so plainly.

Flat roofs in Ashburton
With Addington Palace about 2.4 miles south-east, Ashburton sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Ashburton is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Parking in Ashburton, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway when you book. If your home is one of the older ones in the streets near Church of St Luke, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Ashburton is about 6 miles south of New Cross, in Greater London. Whether the building in Ashburton is a house, a flat or a commercial unit, the roof can be surveyed. We cover towns and villages across Greater London. London is in our area too.

How the survey changes by roof type
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Suitability for ELD depends on the system.
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Useful tips for Ashburton property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Note where leaks show inside and when
- Ask contractors to protect the membrane
- Consider ELD before paving or planting goes on
- Stay off the flat roof unless needed
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Don’t leave a flat roof leak running. Water under a membrane can spread.
Checking the roof from the ground
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
Landlord and commercial surveys in Ashburton
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Letting agents can arrange access with tenants. We survey on weekdays and at weekends, which helps when tenants work during the week.
Signs you need electronic leak detection in Ashburton
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Typical things we are asked to look at include:
- Stains far from any visible defect
- Breaches hidden under paving or planting
- Leaking laps in the waterproofing
- Repairs that haven’t stopped the leak
For site and facilities teams at buildings such as St Thomas Becket Catholic Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

- Is there a chance to talk the report through?
- What the survey won’t cover
- Whether the inside of the roof is included
What happens on the day
Once we have finished looking, we write up our findings in a report with photos. As for time on site, it normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before the survey
- Check pets are kept safely away
- Make sure the loft hatch can be reached
- Unlock side gates and any roof access doors
