Electronic leak detection in Gosport: what you get
Our ELD report shows where each breach was found, with photographs. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs aren’t part of the report; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We survey roof terraces and balconies, flat roof membranes and commercial flat roofs, and the problems we’re asked to look at most are failed seams and laps and leaks through a flat roof with no obvious cause.
Houses around a town like Gosport frequently have a flat roof somewhere, over an extension, garage, porch or dormer. Many are felt, and newer ones may be EPDM rubber or GRP. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Water that sits for days after rain is often the first sign a flat roof needs attention.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

FAQs for Gosport
Does being near the coast affect roofs in Gosport?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it normally shows, and Gosport is within about 2 miles of the coast.
Do you cover commercial flat roofs around Gosport?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing usually needs a wet surface and high-voltage methods need the membrane dry and exposed.
Do you look in the roof space?
If there is a loft and safe access to it, yes. The loft space can show things the outside cannot, such as damp timbers, staining or daylight.
Is this an asbestos survey?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and they go into the written report.
How many surveys have you done?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Have roof specifications to hand
- Don’t leave water getting in
- Keep foot traffic on flat roofs to a minimum
- Use boards when working on the roof
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Can I check my roof myself?
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
What we can’t see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:

Prices for electronic leak detection in Gosport
We confirm the price for the job before booking. These are the things that affect it:
- Building height and the viewpoints available
- Any need for thermal images or a drone flight
- How many separate roofs there are, such as extensions, dormers and garages
- The shape of the roof and its details
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before booking.
Helping us price your survey

How it works
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 photos go into the written report. The visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. A visit in Gosport runs most smoothly with the loft hatch clear, side gates open and a parking spot in mind. Someone needs to let us in, so let us know who that will be.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- If you are buying, let the agent know when we’re coming
- If the roof is shared, arrange access with whoever manages the building
- Keep pets out of the way during the survey
Book a survey
Booking is simple: just call 07833 053749 or email us, let us know about the property and we will explain which survey suits. The price is agreed up front.

Electronic leak detection in Gosport: local notes
Gosport lies within about 2 miles of the sea, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Some Hampshire villages still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
A roof leak in a hotel or guest house around Gosport means lost rooms as well as repairs, so it is worth knowing the roof’s condition. If you live in an older home near St Faith's Church, the flat roofs on later extensions tend to wear out long before the main roof. Landlords with a home close to Portsmouth Harbour station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What else we do in Gosport
What happens if roof problems are left?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. On homes in Gosport, 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.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
