Electronic leak detection around Oaklands
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Digswell House, about 1.8 miles south, show how far back building in the area around Oaklands goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
For an older house near a landmark such as Church of St Michael and All Angels, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Take a building like Oaklands Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For landlords with property near Welwyn North station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Electronic leak detection in Oaklands
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD won’t 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 cannot give results. Common reasons to book are leaks that return after repairs and failed seams and laps, on commercial flat roofs, flat roof membranes and single-ply roofs.
In a smaller place like Oaklands, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report works through the roof section by section, from the coverings down to the gutters. You will see the good as well as the bad.

Landlords, agents and block managers in Oaklands
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Tips that help
From years of surveys, a few habits stand out:
- Act on new leaks promptly
- Find the breach before more patching
- Have roof specifications to hand
- Consider ELD before paving or planting goes on
Questions about the results are welcome. We can talk you through the findings.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
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. Arranging work in a smaller place like Oaklands is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
To find out what your survey will cost, phone 07833 053749 or email us with the address and some details. The price is agreed before a date is set.

DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
FAQs for Oaklands
Will you come out to Oaklands?
Yes, we do. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Do you carry out roof surveys in Oaklands?
Yes, Oaklands is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or email us with the address and some details.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
Will you walk on the roof?
Only if it is safe. We look at everything that can be seen safely: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Do you use drones?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What happens on the day
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. A typical visit takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. A visit to a smaller place like Oaklands is no different on the day: we look from ground level, from windows, from the loft and from the roof where it’s safe. It helps to show us anything you’ve already noticed.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Make sure we can get to the back of the property
- Let us know about parking before the day
How to book
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or drop us an email.
Advice
When you need someone else
Some things can’t be seen without opening up the roof, and that sets some limits:
- Sections we cannot safely access
- Fixing the holes we find
- Build-ups without a suitable layer below
If in doubt, call 07833 053749 or drop us an email and we’ll recommend the right survey. The full list of what we check.
