Electronic leak detection in Forest Hill, Oxfordshire
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Forest Hill, with photos and a clear written report.
- Punctures from foot traffic or tools
- Gaps at membrane joints
- Breaches hidden under paving or planting
Electronic leak detection in Forest Hill
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We do not estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photographs. We’re often asked to look into gaps at membrane joints and repairs that haven’t stopped the leak, on flat roof membranes, commercial flat roofs and single-ply roofs.
In a village or hamlet like Forest Hill, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to.

Common questions in Forest Hill
Do you cover Forest Hill?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is Forest Hill within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We are a CAA-registered drone operator.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
How do I book a survey in Forest Hill?
Simply phone 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Will you walk on the roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest, and the report records anything we couldn’t see.
Practical tips
There is plenty you can do without going near the roof. Here’s what helps most:
- Share any drawings of the roof
- Check new waterproofing before handover
- Ask contractors to protect the membrane
- Limit access to the roof
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
Roof by roof
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Bituminous membranes
Bituminous roofs frequently have laps and old repairs that can leak. Testing depends on the roof.
Electronic leak detection around Forest Hill
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Forest Hill has a long history of building, with Garsington Manor about 3.6 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
If you look after a shop, office or commercial unit, for instance near Templars Square, a flat roof over a business is out of sight and out of mind until it leaks. Take a building like Sandhills Community Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Take an older house close to Church of St Nicholas: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. It normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Forest Hill, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- 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.
How to prepare
- Let us know where we can park nearby
- For flats, make sure roof access has been agreed
- Keep pets out of the way during the survey
Booking a survey
Most bookings start with a short call: ring 07833 053749 or drop us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
What affects the price in Forest Hill
When we price a survey, we consider:
- Height and safe access
- The roof’s overall size
- Commercial roofs and larger buildings
- How many separate roofs there are, like extensions, dormers and garages
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Getting in touch
Before you get in touch, it’s useful to have:
- The property’s address and postcode
- What’s prompted the survey
- Any deadline, such as an exchange date
- What kind of property and roof it is
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, phone 07833 053749 or use the contact form.
