- Leaks that are hard to trace
- Wet insulation beneath the membrane
- Damp around roof outlets and upstands
Thermal roof surveys for homes and businesses in Hadley
A thermal survey is not a quick fix for every roof problem. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That is why we check findings with moisture readings and a close visual inspection. Our report says plainly what the camera picked up and how sure we can be. If a finding can’t be confirmed, the report suggests a next step. If you’re worried about moisture around outlets and upstands and missing or slipped insulation, a survey will tell you what’s going on, whatever the roof.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. We take care to focus on the roof we’ve been asked to look at, in Hadley as anywhere. Tell us about the building and access as you book. The extra view helps most on steep slopes, tall stacks and rear additions.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Before and after the survey
There is plenty you can do without going near the roof. Here’s what helps most:
- Photograph damp patches with the date
- Let us know where and when you’ve seen damp or stains
- Check outlets after heavy rain
- Remember the conditions on the day affect the results
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it is easy to find each area on the roof.
Make sure loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the roof space.
How the survey changes by roof type
Pitched slate and tile roofs
Slate and tile roofs are frequently harder to read with a thermal camera, because of the air space beneath. We back up what the camera shows with a look in the loft where we can.
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.

Leave it or get it looked at?
Without thermal imaging, the only way to see how far water has spread is often to open up the roof. That helps you and your roofer decide what really needs replacing. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there’s time to plan.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.

What we are asked to look at in Hadley
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there’s a clear difference between inside and outside.
Common reasons to book include:
- Wet insulation beneath the membrane
- Areas losing heat at the eaves and junctions
- Missing or slipped insulation
- Water that travels before it shows
Take a building like Susi Earnshaw Theatre School: a drone or thermal camera can show a large roof in a single visit.
Questions to ask before you book

- Whether VAT is in the quoted price
- Are they insured for the work?

Airspace, weather and Hadley roofs
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Steep or complicated roofs are often hard to see from the ground, which is where close-up aerial shots and thermal images help. Wyllyotts Manor, about 2.8 miles north, is one of the historic houses in the wider area around Hadley. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Controlled parking zones are common in London, so mention any permit rules for Hadley. If you look after a shop, office or commercial unit, for instance near Spires Shopping Centre, thermal images can show trapped moisture across a wide commercial roof.
Hadley is about 1 mile north-west of Barnet, in Greater London. We carry out thermal roof surveys for homeowners, landlords and businesses in Hadley. Hadley is one of the towns and villages in Greater London where we work. You can also see our page for London.
We survey roofs across the EN5 and EN4 postcode area for thermal roof surveys. We cover properties on Byng Road, Park Road and Dury Road and the roads around them.

Questions from Hadley
Are there drone restrictions around Hadley?
That depends on where the roof is and on the weather. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and 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. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
How do I find out if my home in Hadley is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
What happens next?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
How do I book a survey in Hadley?
To book, call 07833 053749 or use the contact form and let us know the address and what you want to find out. We’ll confirm the price and agree a day with you.
Does this replace a RICS home survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Does the report include photos?
Yes, every report has them. Pictures sit next to the findings they show.
What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes roughly 1–2 hours for most houses, though large, tall or awkward roofs take more time. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Hadley runs like any other.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
How to book
Our price is from £400, including VAT. What you pay depends on the roof’s size, access and the package, so phone 07833 053749 or drop us an email with the details.
