FAQs for Great Leighs
Will you come out to Great Leighs?
Yes. Great Leighs is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Does a conservation area affect roof work in Great Leighs?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Will you go up on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
About our electronic leak detection in Great Leighs
Our ELD report shows where each breach was found, with photographs. Your roofer can then repair those points rather than guessing. We don’t estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. We survey flat roof membranes, green roofs and commercial flat roofs, and people most often book us about holes around roof penetrations and failed seams and laps.
Older buildings in small places like Great Leighs may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What this survey can’t tell you
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Water entering through details rather than the membrane
- Build-ups without a suitable layer below
- Parts of the roof covered by fixed equipment
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we’ll tell you before you book. What a survey covers and doesn’t.

Different roofs, different checks
EPDM rubber roofs
EPDM rubber roofs often last 30–50 years, but punctures and seam failures still happen.
Bituminous membranes
Bituminous roofs often have laps and old repairs where breaches occur. We test where the roof suits it.
Practical tips
Most of what helps is simple and safe from the ground. A few suggestions:
- Keep foot traffic on flat roofs to a minimum
- Check new waterproofing before handover
- Don’t let outlets block
- Note where leaks show inside and when
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Electronic leak detection in Great Leighs: local notes
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building like Great Leighs Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Cressing station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If your house is among the older ones in the streets near Church of St John the Evangelist, the flat roofs on later extensions tend to wear out long before the main roof.

How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes as long as needed for the roof’s area and construction, and we’ll give you a guide when quoting. If you have questions on the day, just ask. Older roofs in small places like Great Leighs can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Let us know about parking before the day
- Have any paperwork from past roof work to hand
- Jot down any questions you want answered
Booking a survey
A quick phone call is normally the easiest start: phone 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

Rented homes, blocks and businesses
Where a roof is shared: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the survey around it.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photographs included.
Checking the roof from ground level
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
