How electronic leak detection works in Ashford Common
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we will say so. Common reasons to book are leaks through a flat roof with no obvious cause and leaks under green or ballasted roofs, on roof terraces and balconies, flat roof membranes and liquid-applied waterproofing.
In a smaller place like Ashford Common, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photographs included.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
What a survey costs
To price your survey, we look at:
- How big the roof is
- Chimneys, valleys, parapets and other details
- The number of roofs, including extensions and garages
- Building height and the viewpoints available
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Booking your survey
Here’s what helps us most when you contact us:
- Any deadline, such as an exchange date
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
- What’s prompted the survey
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us.
How it works
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit typically takes as long as needed for the membrane area and the build-up, which we set out in the quote. For a survey in Ashford Common, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Leave a clear route to the loft
- Mention any parking restrictions on your street
- If you’re buying, let the agent know when we are coming
Getting a price
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or email us.

- Damage from equipment installers
- New membranes needing a check before handover
- A flat roof leak that cannot be traced
- Holes around roof penetrations
For landlords with property near Upper Halliford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What else we do in Ashford Common
Checking the roof from the ground
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in, using safe viewpoints and a drone where applicable.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
When you need someone else
It is useful to know what a survey won’t do before booking:
- Leaks from walls, copings or rooflights
- Fixing the holes we find
- Roofs whose membrane or build-up isn’t suitable
If in doubt, ring 07833 053749 or send us an email and we’ll point you to the right survey. What a survey covers and doesn’t.
What this survey covers
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
- Roof terraces and balconies
- Single-ply roofs
- Green roofs
What electronic leak detection looks like in Ashford Common
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Horsham stone slab roofs survive on some old buildings in Surrey. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 4.6 miles east lies Strawberry Hill House, a reminder of how long the area around Ashford Common has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
For an older house near a landmark such as St Saviour, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Take a building like Meadhurst Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Questions from Ashford Common
How do I find out if my home in Ashford Common is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover Ashford Common?
Yes, Ashford Common is one of the places we work. Every survey there gets the same written report with photos.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Is the repair part of the test?
No, our part is finding the breaches. The report gives your roofer the locations.
Does this replace a RICS home 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.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
