Electronic leak detection for homes and businesses in Lower Upnor
There are different ELD methods. Low-voltage testing is normally 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. We’ll say if your roof doesn’t suit either method before any testing starts. We are often asked to look into stains far from any visible defect and waterproofing to test before it’s covered, across green roofs, commercial flat roofs and single-ply roofs.
In a small place like Lower Upnor, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Landlords, agents and block managers in Lower Upnor
Any of our surveys can be booked by landlords, agents and building managers in Lower Upnor. To discuss a property or a block, call 07833 053749 or email us.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it as you book and we will plan the survey around it.
What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. Around Lower Upnor, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We agree the area to be tested.

Advice
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. For older village homes like those around Lower Upnor, the right replacement materials are not always easy to find quickly. That’s one more reason to find defects before they become urgent.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Lower Upnor questions
Will you come out to Lower Upnor?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is my home in Lower Upnor listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Does ELD work under paving or planting?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We will discuss it before we quote.
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, while high-voltage testing needs a dry, exposed membrane.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What happens next?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Electronic leak detection in Lower Upnor: local notes
Lower Upnor lies within about 2 miles of the sea, so there is more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Restoration House, about 2 miles south-west, is one of the historic houses in the wider area around Lower Upnor. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
For an older house near a landmark like St Philip & St James, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a shop, office or commercial unit, for example near Pentagon Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. Anyone responsible for a site like Chattenden Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
