Electronic leak detection in Alresford
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. It’s testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey green roofs, commercial flat roofs and roof terraces and balconies, and the problems we are asked to look at most are new roofs to check before paving or planting and holes left by work on the roof.
In a smaller place like Alresford, some flat roofs sit in the open, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.

What happens on the day
After the inspection, everything we found is written up as a written report with photos, sent to you by email. As for time on site, it typically takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. Parking around Alresford is usually easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- 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.
- The testing method is chosen to suit the membrane and build-up.
- 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.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors

Alresford: your questions answered
Is my home in Alresford listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Is the coastal weather around Alresford hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Do you cover Alresford?
Yes, we do. We carry out electronic leak detection in Alresford.
How much time does ELD need?
Testing usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
Can every flat roof be tested?
It depends on the membrane and the build-up. Share any details you have and we’ll check whether ELD will work.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
Electronic leak detection around Alresford
Alresford is within about 2 miles of the coast, 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. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
For an older house near a landmark such as Saint Andrew's Church, the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Alresford Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Alresford station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

How the survey changes by roof type
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
When you need someone else
It helps to know what a survey won’t do before you book:
- Areas we cannot reach or that cannot be tested
- Leaks from walls, copings or rooflights
- Carrying out the repair work
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer before booking. What our survey covers.
What this survey covers
- Single-ply roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Flat roof membranes
- Green roofs
- Commercial flat roofs
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Blocked gutters on homes around Alresford overflow and soak walls, especially where trees overhang. It’s easy to sort the cause early and slow to dry a damp wall.
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.
