Thermal Roof Survey in Mackerye End
An experienced roof surveyor for thermal roof surveys in Mackerye End. Over 5,000 surveys and 20+ years behind us across London and the South East.
- Damp that repairs haven’t cured
- Missing or slipped insulation
- Areas of a flat roof that may hold water
What we look for on each type of roof
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. The camera can give clues to where it’s sitting, given suitable conditions on the day.
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. We combine a close visual check with the thermal images.
About our thermal roof survey in Mackerye End
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there’s safe access. If you’ve noticed missing or slipped insulation and leaks far from where the stain appears, we can find out what’s behind it.
In a village or hamlet like Mackerye End, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Weather and airspace are checked before the visit, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

FAQs for Mackerye End
Is drone flying allowed in Mackerye End?
That depends on where the roof is and on the weather. Mackerye End is about 1 mile from the edge of the flight restriction zone around Luton Airport. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. Strong wind or a downpour also stops a small drone flying, and the rest of the survey does not depend on the drone.
Will you come out to Mackerye End?
Yes, Mackerye End is covered. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
What do I do with the report?
The report arrives by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know when you book.
Can a thermal survey trace a roof leak?
It is a useful tool for tracing leaks, but not the only one. The results depend on conditions on the day. If the source cannot be confirmed, we’ll say what could help next, like electronic leak detection.
What does a thermal roof survey show?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.

Why act early in Mackerye End
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, rather than more guesswork. In a place like Mackerye End, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.
Prices start from £150, with VAT included, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. You’ll know the price for your survey before booking.

What happens on the day
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Rural addresses near Mackerye End can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s 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.
Preparing for the visit
- Agree roof access with the managing agent if it’s shared
- Find any records of previous roof work
- Mention any parking restrictions on your street

Advice
Do you need a thermal roof survey in Mackerye End?
People often book a thermal survey when a damp patch has no obvious cause. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Look out for signs like these:
- Damp around roof outlets and upstands
- Damp that repairs haven’t cured
- Areas losing heat at the eaves and junctions
- Water that travels before it shows
If you look after a building like Sauncey Wood Primary School, thermal images can show where wet insulation sits under a big flat roof.
What to check before booking
- What happens after the report arrives
- Whether VAT is in the quoted price
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Will they check the loft as well as the outside?
Drones, thermal imaging and Mackerye End roofs
The wider area around Mackerye End has a long history of building, with Shaw's Corner about 2.3 miles east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
Take an older house close to All Saints: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.
