Questions from Langley
Do you cover smaller places like Langley?
Yes. Langley is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
How do I find out if my home in Langley is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
How experienced are you?
We have more than 20 years’ experience 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. 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.
Will you go up on the roof?
Only where it’s safe to do so. We inspect what can be seen safely: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where applicable. Anything we can’t see is noted in the report.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put in order of urgency where relevant.
How electronic leak detection works in Langley
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. If you are worried about leaks through a covered membrane and patched roofs that still leak, a survey will tell you what’s going on, on single-ply roofs, green roofs and commercial flat roofs alike.
In a smaller place like Langley, some flat roofs sit in the open, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

Why act early in Langley
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. Homes in smaller places like Langley can face more weather, so a loose ridge or verge soon lets rain in. Wind gets under it and lifts more, and water follows.

Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Note where leaks show inside and when
- Share any drawings of the roof
- Don’t keep patching the same spot
- Keep outlets clear of debris
Questions about the results are welcome. We can talk you through the findings.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
The survey, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Homes around Langley often have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Unlock side gates and any roof access doors
- For a flat or shared roof, check access with whoever owns or manages the building
- Tell us about any leaks, stains or damp patches you know of
Book a survey
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.

Should I look at the roof myself first?
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book and it will help the survey.
What this survey cannot tell you
A survey is a proper look at the flat roof membrane, but it can’t do everything. Its limits include:
- Repairing the breaches (that’s for your roofer)
- Areas we can’t reach or that can’t be tested
- Leaks from walls, copings or rooflights
If in doubt, phone 07833 053749 or use the contact form and we’ll recommend the right survey. What a survey covers and doesn’t.

Flat and commercial roofs around Langley
The wider area around Langley has a long history of building, with Windsor Castle about 2.7 miles south-west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you let a flat or house near Langley station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like The Langley Academy Primary will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Common roof problems in Langley
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
A survey can pick up problems such as:
- Water coming in under a flat roof
- Waterproofing to test before it is covered
- Repairs that haven’t stopped the leak
- Leaking laps in the waterproofing
The streets around a church such as St Mary the Virgin Church are often among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems usually start.
