Electronic leak detection in Petersfield
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly, to find where it has been breached. It is testing only, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. Typical surveys look at a flat roof leak that can’t be traced and leaks through a covered membrane, on green roofs, commercial flat roofs and flat roof membranes.
Garages and porches on estates in towns like Petersfield often have flat roofs. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed. Felt, rubber and fibreglass coverings each need a different approach. Asbestos testing is not part of what we do, though a report may flag materials that could contain it.
Findings are set out part by part, from the coverings down to the gutters. It records what’s sound as well as what is not.

How it works
It helps 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. Most visits take a length of time set by the size of the roof and how it’s built, which we set out in the quote. A survey in Petersfield needs access inside and out, including the loft hatch and any rooms with damp. Mention gates, side passages and anything at the back. Visits can be on weekdays, Saturdays or Sundays.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- If you are buying, check with the agent that we can get in
- Make sure pets are kept safely away
- Agree roof access with the managing agent if it’s shared
Booking a survey
Booking is simple: just call 07833 053749 or drop us an email, let us know about the property and we will explain which survey suits. The price is agreed up front.

Landlords, agents and block managers in Petersfield
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant in advance.
Prices for electronic leak detection in Petersfield
To price your survey, we look at:
- The height of the building and how the roof can safely be seen
- The size of the roof
- The number of roofs, including extensions and garages
- Whether it is a home or a commercial building
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

Different roofs, different checks
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Electronic leak detection around Petersfield
Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 4.1 miles south-east lies Uppark, a reminder of how long the area around Petersfield has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Petersfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Anyone responsible for a site like Petersfield Infant School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For an older house near a landmark like St Peter's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Leave it or get it looked at?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. Around Petersfield, gutters that overflow soak the wall below. A slipped tile or worn flashing does the same higher up. Left alone, both only get worse.
The cost of a survey depends on the roof: 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.

Petersfield: your questions answered
Is my home in Petersfield listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
What do I need to do before a survey in Petersfield?
The main thing is access, inside and out, plus somewhere to park in Petersfield. Let us know about known leaks or past repairs as well.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
How experienced are you?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
Do you cover Petersfield?
Yes. Petersfield is part of the area we cover, and the service is the same as everywhere else we work.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Other services in Petersfield
Should I look at the roof myself first?
What you cannot 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 it applies.
You can learn a lot from ground level. 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.
