Electronic leak detection in Hollywater, Hampshire
Know where you stand with the flat roof membrane before you spend money on it. We carry out electronic leak detection in Hollywater.
- A flat roof leak that cannot be traced
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
Common roof problems in Hollywater
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
These are some of the problems a survey can pick up:
- Leaks at pipes, outlets or fixings
- Repairs that haven’t stopped the leak
- Damp inside with no sign on the roof
- Holes left by work on the roof
If you look after a building like Woodlea Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Hollywater
There are different ELD methods. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we will explain our choice. We will say if your roof doesn’t suit either method before any testing starts. If you are worried about stains far from any visible defect and a flat roof leak that can’t be traced, a survey will tell you what’s going on.
Some older homes in villages like Hollywater are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

What electronic leak detection looks like in Hollywater
A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there.
If your house is among the older ones in the streets near St Mark's Sacred Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you own a rental within reach of Liphook station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Hollywater is about 6 miles south-east of Alton, in Hampshire. Surveys in Hollywater work the same way as everywhere we cover: a careful inspection, photos and a written report. Our Hampshire coverage includes Hollywater and the places around it. For surveys nearby, see our Guildford page.

Why act early in Hollywater
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. Around Hollywater, older homes frequently have old roof timbers, where water from a failed roof can cause rot if it is left.
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 the job before booking.

How the survey changes by roof type
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but can still be punctured.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Common questions in Hollywater
Does a conservation area affect roof work in Hollywater?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you carry out roof surveys in Hollywater?
Yes, Hollywater is one of the places we work. The survey and report are the same in Hollywater as anywhere else.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
Does the weather affect the survey?
It can, depending on the survey. Drones cannot fly safely in high wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
What affects the price in Hollywater
Prices always include VAT. What changes the price is:
- The roof’s overall size
- The use of thermal imaging or a drone
- The number of roofs, including extensions and garages
- Commercial roofs and larger buildings
To find out what your survey will cost, phone 07833 053749 or send us an email with the address and some details. The price is agreed before a date is set.
Helping us price your survey
Before you get in touch, it helps to have:
- Any marks or damp showing indoors
- When you need the report by
- Whether there’s a loft hatch, a shared roof or tricky access
- Any photos you have, taken from ground level or a window
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.
How it works
The visit has one job: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photographs go into the written report. The visit normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a small place like Hollywater, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Preparing for the visit
- Mention any parking restrictions on your street
- Leave side gates unlocked
- If it is not your property yet, arrange access through the agent

Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Share any drawings of the roof
- Note where leaks show inside and when
- Test new membranes before covering them
- Do not let outlets block
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
