Electronic leak detection in Addlestone: what you get
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We will say if ELD will not work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that can’t give results. Typical surveys look at stains far from any visible defect and failed seams and laps, on liquid-applied waterproofing, roof terraces and balconies and single-ply roofs.
Flat roofs in smaller places like Addlestone can be more exposed, especially where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.
Every survey ends with a written report, with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

When to book a survey in Addlestone
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
Typical things we are asked to look at include:
- New roofs to check before paving or planting
- Patched roofs that still leak
- Damp inside with no sign on the roof
- Leaks at pipes, outlets or fixings
If you live in an older home near St Paul's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What we do, step by step
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Homes around Addlestone frequently have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. Inside, the loft is checked where it can be reached safely.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Preparing for the visit
- For a flat or shared roof, check access with the freeholder or managing agent
- If you are buying, check with the agent that we can get in
- Leave side gates unlocked

How we price electronic leak detection
Not every roof costs the same to survey, for these reasons:
- Features like valleys, chimneys, dormers and parapets
- How big the roof is
- Commercial roofs and larger buildings
- The use of thermal imaging or a drone
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.
Helping us price your survey
The more you tell us, the easier it is to price the survey. When you get in touch, it helps to mention:
- Where the property is, with the postcode
- Where water is showing inside, if it is
- Pictures from the garden or a window, if you have them
- The style of property, from a terrace to a block
We survey roofs seven days a week. To find a date that works for you, call 07833 053749 or use the contact form with the address and the days you’d prefer.
Common questions in Addlestone
Will you come out to Addlestone?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Does a conservation area affect roof work in Addlestone?
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.
Does ELD include fixing the breach?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
What’s the best way to book?
The quickest way is to call 07833 053749 or drop us an email. Give us the address and a few details about the roof, and we will take it from there. Surveys run seven days a week.
How much time does ELD need?
It typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Do you need to get into the loft?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Electronic leak detection around Addlestone
In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Addlestone has a long history of building, with Botleys Mansion about 1.8 miles west. 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 Addlestone station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For site and facilities teams at buildings such as Darley Dene Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Bituminous membranes
Bitumen roofs can often be tested electronically, depending on what’s below.
Useful tips for Addlestone property owners
Most of what helps is simple and safe from ground level. A few suggestions:
- Clear flat roof outlets regularly
- Have roof specifications to hand
- Keep a note of leaks after rain
- Do not leave water getting in
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
