About our electronic leak detection in Dorking
Our ELD testing covers flat roofs in Dorking and the rest of London and South East England. A visit usually takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. If you are worried about new membranes needing a check before handover and holes left by work on the roof, we can find out what’s behind it, on single-ply roofs, commercial flat roofs and green roofs alike.
In a town like Dorking, flat roofs are common on rear extensions, garages, porches and dormers. Many are felt, and newer ones may be EPDM rubber or GRP. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is often the first sign a flat roof needs attention.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Rented homes, blocks and businesses
Any of our surveys can be booked by landlords, agents and building managers in Dorking. To discuss a property or a block, phone 07833 053749 or drop us an email.
Letting agents can arrange access with tenants, at a time agreed beforehand. We survey on weekdays, Saturdays and Sundays, which can make access easier.
Should I look at the roof myself first?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Flat and commercial roofs around Dorking
There are several hotels within about a mile and a half of Dorking, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use. Historic houses such as Polesden Lacey, about 2.7 miles north-west, show how far back building in the area around Dorking goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you run a hotel or guest house in or near Dorking, a roof problem can mean rooms out of use, so it pays to find faults before guests do. If you live in an older home near Church of St Paul, the flat roofs on later extensions tend to wear out long before the main roof. For site and facilities teams at buildings like St Paul's CofE (Aided) Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

How the survey works
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect a time that depends on the membrane area and the build-up, which we set out in the quote. Parking in a town like Dorking is normally simple, but tell us if there’s a driveway or any restrictions. We look at the roof from the ground and from windows, then from the loft where there is safe access.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Check we can get to the back of the property
- Buyers: confirm access with the estate agent or seller
- Keep pets inside or away from the areas we are looking at

FAQs for Dorking
Is my home in Dorking listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 Dorking?
We do. The survey and report are the same in Dorking as anywhere else, and visits run on weekdays and weekends.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We will discuss it before we quote.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can you survey a shared roof?
Yes, if the building owner or managing agent agrees access. We look at the parts we’re given access to, and the report makes that clear.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
When you need someone else
To be straight with you, a roof survey has limits:
- Fixing the holes we find
- Sections we can’t safely access
- Some conductive membranes
If in doubt, ring 07833 053749 or send us an email and we’ll recommend the right survey before booking. What a survey covers and does not.
What we look at
- Single-ply roofs
- Green roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Commercial flat roofs
- Flat roof membranes
Roof by roof
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers, depending on the build-up.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. On homes in Dorking, the joint between an extension and the house is where a slow leak tends to start. A few wet winters later, it can mean new plaster and decorating as well as roof work.
To find out what your survey will cost, ring 07833 053749 or send us an email with the address and some details. The price is agreed before a date is set.
