Useful tips for Hornchurch Marshes property owners
A survey works best with a little help from you, before and after. Some tips:
- Limit access to the roof
- Find the breach before more patching
- Get leaks traced quickly
- Record dates and spots where water appears
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
Electronic leak detection in Hornchurch Marshes
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs aren’t part of the report; that’s for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. Results come in a written report with photos. If you’re worried about holes around roof penetrations and stains far from any visible defect, a survey will tell you what’s going on, whatever the roof.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Hornchurch Marshes, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

Hornchurch Marshes questions
Is Hornchurch Marshes in the area you cover?
Yes, Hornchurch Marshes is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
How do I find out if my home in Hornchurch Marshes is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
Does the report include photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What a survey costs
When we price a survey, we consider:
- The height of the building and how the roof can safely be seen
- Whether thermal imaging or a drone is needed
- The roof’s overall size
- Extensions, dormers and garages with roofs of their own
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Helping us price your survey
There’s no need for technical words. It is enough to let us know:
- Pictures of the roof from a safe spot, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- Dates you are working to, such as exchange
- What kind of property and roof it is
To get a price for electronic leak detection in Hornchurch Marshes, call 07833 053749 or email us. A few details about the property and the roof help us give you an accurate price.
What electronic leak detection doesn’t cover
We only report what can be seen safely on the day, so some things are outside what a survey can do:
- Some conductive membranes
- Areas we can’t reach or that can’t be tested
- Water entering through details rather than the membrane
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. What a survey covers and does not.

Flat roofs in Hornchurch Marshes
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Rainham Hall, about 1.1 miles east, is one of the historic houses in the wider area around Hornchurch Marshes. 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.
For businesses in and around places such as Gallions Reach Shopping Park, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Controlled parking zones are common in London, so mention any permit rules for Hornchurch Marshes, along with any off-street space. If you let a flat or house near Dagenham Dock station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Leave it or get it looked at?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. In Hornchurch Marshes, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
What you get with us
- An independent view of the roof
- Drones and thermal imaging where applicable
- Two decades and more of roof surveys
- CAA-registered drone operator (Flyer ID and Operator ID)
How it works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and make notes for the report. It typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. London terraces rarely offer a view of the whole roof from one spot, so a visit in Hornchurch Marshes moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Note where any stains or damp appear
- If it isn’t your property yet, arrange access through the agent
- Have any paperwork from past roof work to hand
Booking a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you’re ready.
Related advice
Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
