Stonymarsh Electronic Leak Detection
Electronic leak detection across Stonymarsh, backed by more than 20 years’ experience. Every survey ends with a written report and photos.
- Damp inside with no sign on the roof
- Repairs that haven’t stopped the leak
- Waterproofing to test before it is covered
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in.
Electronic leak detection in Stonymarsh
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. We survey green roofs, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are punctures from foot traffic or tools and gaps at membrane joints.
Flat roofs on exposed homes in small places like Stonymarsh take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which frequently last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Questions from Stonymarsh
How do I find out if my home in Stonymarsh is listed?
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.
Is Stonymarsh in the area you cover?
Yes. We work right across London and the South East, and Stonymarsh is part of that. You can ring 07833 053749 or drop us an email with the address and a few details.
How do you choose the testing method?
The roof decides the method. We will explain why when we quote.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years, and 98% of customers are satisfied.
Does the report include photographs?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
What will the report tell me?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Electronic leak detection around Stonymarsh
Some Hampshire villages still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 0.5 miles west lies Mottisfont Abbey, a reminder of how long the area around Stonymarsh has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Mottisfont & Dunbridge station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If your house is among the older ones in the streets near Church of St Andrew, the flat roofs on later extensions tend to wear out long before the main roof.
Stonymarsh is about 4 miles north-west of Romsey, in Hampshire. If you’re in Stonymarsh, booking works exactly as it does anywhere else: a call or an email, a price, then a date. We cover towns and villages across Hampshire. There’s also a page for Southampton.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Use boards when working on the roof
- Note where leaks show inside and when
- Do not let outlets block
- Consider ELD before paving or planting goes on
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.

The survey, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. The visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Stonymarsh needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- If it is not your property yet, arrange access through the agent
- Make a note of anything you’d like us to look at

We survey roofs for letting agents and landlords as well as homeowners. A written report with photographs gives you a clear record of the flat roof membrane.
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Height and safe access
- House, block, shop or office
- Features like valleys, chimneys, dormers and parapets
- Extensions, dormers and garages with roofs of their own
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your survey before you book.
Helping us price your survey
There is no need for technical words. It is enough to tell us:
- The type of building and roof, such as pitched or flat
- Your timetable, such as an exchange date
- Photos of the roof, taken safely from ground level or a window
- What made you get in touch
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To get started, ring 07833 053749 or email us.
