South Harefield Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in South Harefield. We’ve completed more than 5,000 surveys across London and the South East.
- Moisture around outlets and upstands
- Stains that keep coming back
- Wet insulation beneath the membrane
Roof by roof
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
About our thermal roof survey in South Harefield
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. Those patterns can point to trapped moisture, missing insulation or heat escaping. It’s important to know that the camera shows temperature, not water, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We’re frequently asked to look into damp that repairs haven’t cured and leaks far from where the stain appears, on flat roofs, ceilings below the roof and insulated roof spaces.
Older buildings in small places like South Harefield may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
If any part of the roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Thermal roof surveys in South Harefield: local notes
About 2.7 miles south-east lies Ickenham Hall, a reminder of how long the area around South Harefield has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. A number of Buckinghamshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
If you look after a building such as Harefield Infant School, a view from above covers a wide roof far faster than walking it. If you run a business near The Pavilions, thermal images can show trapped moisture across a wide commercial roof. The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if your home is one of the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image.

For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the visit with that in mind.
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

Prices for thermal roof surveys in South Harefield
We confirm the price for your survey before you book. This is what makes a difference:
- Features like valleys, chimneys, dormers and parapets
- Which survey package you book
- The use of thermal imaging or a drone
- Commercial roofs and larger buildings
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
A little information up front helps. Please include:
- The kind of building and roof involved
- Any deadline, like an exchange date
- Photos of the roof, taken safely from ground level or a window
- Why you want a survey: buying, a leak, a storm or new work
Most bookings start with a short call: call 07833 053749 or use the contact form and we will ask a few questions about the roof. You will have a price before anything is arranged.
Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear leaves from outlets and gutters each autumn
- Use the report as a baseline for later checks
- Talk to us about the weather when booking
- Check from the ground or a window, never by climbing
If the images suggest moisture that can’t be confirmed, we will say what would help next, such as electronic leak detection or opening up a small area.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
South Harefield: your questions answered
Is South Harefield within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is drone flying allowed in South Harefield?
It depends on the exact address and the weather on the day. Denham Aerodrome is about 2 miles away, so we check the Drone Safety Map for restrictions before any flight. A small drone can’t fly safely in strong wind or heavy rain, though the rest of the survey goes ahead either way.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Let us know which days suit you when booking.
Will you go up on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
How do I arrange a thermal roof survey in South Harefield?
Simply phone 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
How long does the survey take?
Most surveys take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. We will confirm the timing when you book.
What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take about 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. Somewhere as small as South Harefield, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.

- You get the report the same day, with an in-person consultation to follow.
Before we arrive
