Forest Row Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes across Forest Row, with drones and thermal imaging where they help. Get in touch for a price.
- Leaks through a covered membrane
- Holes left by work on the roof
- Stains far from any visible defect
Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Keep outlets clear of debris
- Share any drawings of the roof
- Use boards when working on the roof
- Keep a note of leaks after rain
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Electronic leak detection in Forest Row: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Just ask about your roof. If you’ve noticed leaks showing away from the breach and holes left by work on the roof, a survey will tell you what’s going on, whatever the roof.
Flat roofs in smaller places like Forest Row can be more exposed, especially where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away, along with water that sits after rain. Standing water that lingers for days after rain is another sign worth watching for.
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.

What we do, step by step
After the inspection, everything we found is written up in a report with photos. As for time on site, most surveys take as long as needed for the membrane area and the build-up, which we set out in the quote. Homes around Forest Row often have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Keep pets inside or away from the areas we’re looking at
- If the roof is shared, arrange access with whoever manages the building
- Find any records of previous roof work

Prices for electronic leak detection in Forest Row
All our prices include VAT. What changes the price is:
- Height and safe access
- The type of building, from a house to a block or an office
- How complicated the roof is, with its valleys, chimneys and parapets
- How big the roof is
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Here’s what helps us most when you contact us:
- What’s prompted the survey
- Anything about access we should know
- The style of property, from a terrace to a block

Common questions in Forest Row
Is my home in Forest Row listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover smaller places like Forest Row?
Yes, Forest Row is on our map. Villages and rural addresses get the same survey as a town house.
What happens after the survey?
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.
Does the weather affect the survey?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.

Why it is worth a survey now in Forest Row
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. With lower homes, common in places like Forest Row, there is little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Local flat roofs in Forest Row
Standen, about 2.3 miles west, is one of the historic houses in the wider area around Forest Row. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Forest Row Church of England Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to East Grinstead station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you live in an older home near The Parish Church of the Holy Trinity, the flat roofs on later extensions tend to wear out long before the main roof.
