Thermal Roof Survey in Wennington
Thermal imaging to find moisture and heat loss patterns in a roof in Wennington. More than 5,000 surveys completed across London and South East England.
- Damp where roofs meet walls and chimneys
- Leaks that are hard to trace
- Moisture around outlets and upstands
How the survey changes by roof type
GRP fibreglass roofs
Water under a GRP roof can reach the timber deck. Thermal imaging can suggest where that may be happening.
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. Thermal imaging can help show damp patterns around them.
How a thermal roof survey works in Wennington
On a flat roof, wet insulation holds heat longer than dry insulation. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, something you cannot usually tell from the surface. Moisture readings are then used to check what the camera suggests. If you’re worried about cold areas below the roof and wet areas near outlets and upstands, we can find out what’s behind it, on flat roofs, commercial roofs and pitched roof slopes alike.
Many London roofs are hidden from the pavement: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. Drone photos and thermal images can show parts of a roof that are hard to reach safely. Weather on the day decides whether it goes ahead, in Wennington as anywhere. What a thermal image shows is temperature, so anything that looks like moisture is checked with a meter.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Thermal roof surveys around Wennington
Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Wennington is one of them, bay roofs, hips and later dormers each have their own details. Steep or complicated roofs are frequently hard to see from the ground, which is where close-up aerial shots and thermal images help.
Parking in Wennington, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised. The streets around a church such as St Mary and St Peter's Church are often among the oldest in a place, and if you own one of the older houses nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image. Rainham Hall lies about 1.5 miles north-west, so building around Wennington goes back a long way. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition.
Wennington is about 4 miles south of Hornchurch, in Greater London. Wennington is one of many places we visit across Greater London, for houses, flats and commercial buildings. Wennington is one of the places in Greater London we cover. London is in our area too.

Wennington: your questions answered
Can you fly a drone over a roof in Wennington?
The answer turns on the exact location and the conditions on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first. High wind or heavy rain also stops a small drone flying.
Is my home in Wennington listed or in a conservation area?
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.
What happens after the survey?
You will get the report by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Can a thermal survey trace a roof leak?
It often helps show where to look. Patterns can suggest where trapped water has spread. We combine it with a visual inspection and moisture readings because the camera can’t confirm water on its own.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
Is thermal imaging useful on pitched roofs?
It can help, but the results are frequently less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there is safe access.
For landlords and managing agents
Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
Honest limits
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Readings unaffected by sun, shade or reflections
- Hidden layers that need to be opened up to check
- A structural engineer’s assessment

Roofs we survey in Wennington
- Pitched roof slopes
- Flat roofs
- Loft conversions
- Ceilings below the roof
- Insulated roof spaces
- Commercial roofs
What happens on the day
Every roof is different; as a rough guide, the survey takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. You’re welcome to ask questions while we’re there. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Wennington runs like any other.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Before we arrive
- Have any paperwork from past roof work to hand
- Make a note of anything you’d like us to look at
- Move anything stored under the loft hatch
Arrange a survey
Booking is simple: just call 07833 053749 or drop us an email, let us know about the property and we will explain which survey suits. The price is agreed up front.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Check the loft can be reached safely
- Tell us where and when you’ve seen damp or stains
- Keep outlets and gutters clear to stop water sitting
- Leave the roof to people with safe access
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Insulation is frequently moved when people work in the loft space.
Should I look at the roof myself first?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
