Wealdstone questions
Is parking a problem for a survey in Wealdstone?
Typically it’s manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Wealdstone is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we’re allowed to reach.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
How do I arrange electronic leak detection in Wealdstone?
The quickest way is to phone 07833 053749 or email us. Give us the address and a few details about the roof. Surveys run on any day of the week.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
About our electronic leak detection in Wealdstone
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. If neither method suits your roof, we will tell you before any testing starts. Common reasons to book are new roofs to check before paving or planting and a flat roof leak that can’t be traced, across flat roof membranes, green roofs and single-ply roofs.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Wealdstone, the flat roof is frequently a shared part of the building.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

What electronic leak detection looks like in Wealdstone
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Headstone Manor, about 0.9 miles west, is one of the historic houses in the wider area around Wealdstone. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you run a business near St. George's Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you look after a building like Marlborough Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If your home is one of the older ones in the streets near Holy Trinity Church, the flat roofs on later extensions tend to wear out long before the main roof.
Wealdstone is about 2 miles north-east of Harrow, in Greater London. From houses to flats and shops in Wealdstone, we can survey the roof. Our Greater London coverage includes Wealdstone and the places around it. London is in our area too.
We cover every part of HA3, HA1 and HA2 for electronic leak detection. Whether your property is on Tudor Road, Herga Road and Byron Road or a nearby road, we can help. If you’re just outside Wealdstone, we cover Greenhill (1 mile south), Kenton (1 mile south-east), Northwick Park (1 mile south), North Harrow (1 mile south-west) and Harrow (2 miles south-west).

Local landmarks in Wealdstone
Around Wealdstone, our work takes us to homes and buildings near Headstone Manor Recreation Ground, The Sacred Heart Language College and The Duck in the Pond pub. There’s a railway station in Wealdstone itself: Harrow & Wealdstone station. A little further out are Hilfield Castle (4.2 miles north) and Kodak Museum (0.5 miles west). For a walk, there’s Northala Fields and Harrow Weald Common.
What happens if roof problems are left?
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your roof before you book.

Different roofs, different checks
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but punctures and seam failures still happen.
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. We test where the roof suits it.
DIY checks: what’s safe
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.

How it works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a London area like Wealdstone, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from the ground, windows, the loft and, where it’s safe, the roof itself.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Make sure pets are kept safely away
- Have keys ready for side gates, garages or roof access doors

Tips that help
You do not need to be a roofer to help. Here’s what helps most:
- Find the breach before more patching
- Do not let outlets block
- Have roof specifications to hand
- Note where leaks show inside and when
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
