Electronic leak detection in Downham
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing is not possible, we’ll say so. We survey roof terraces and balconies, flat roof membranes and commercial flat roofs, and people most frequently book us about patched roofs that still leak and water coming in under a flat roof.
Flat roofs on exposed homes in small places like Downham take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Questions from Downham
Do you carry out roof surveys in Downham?
Yes, Downham is within the area we cover. We survey roofs across London and the South East. You can call 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
Do you cover smaller places like Downham?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can you survey a shared 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 freeholder or managing agent. We inspect only the parts we are allowed to reach.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather isn’t right.
Other services in Downham
Different roofs, different checks
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
How we price electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- How tall the building is and how easy the roof is to see
- If the survey needs thermal imaging or a drone
- Commercial roofs and larger buildings
- Roof area
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Booking your survey
Getting the details right at the start saves time. It’s useful to include:
- What made you get in touch
- Where the property is, with the postcode
- Any stains, drips or damp patches you’ve seen indoors
- Pictures of the roof from a safe spot, if you have them

Local flat roofs in Downham
The wider area around Downham has a long history of building, with Ingatestone Hall about 4.7 miles west. Older homes in the wider area often 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. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take a building like The Bromfords School and Sixth Form College: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If yours is one of the older homes in the streets near Church of St Margaret, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Wickford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Limit access to the roof
- Have roof specifications to hand
- Check new waterproofing before handover
- Act on new leaks promptly
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
The survey, step by step
We don’t take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof can’t be seen, the report says so. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Downham often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Make a note of anything you’d like us to look at
- Make sure the loft hatch can be reached
- Note where any stains or damp appear
