About our thermal roof survey in Hampstead
Thermal imaging is useful when a damp patch has no clear cause. Leaks often run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. We combine the images with a visual inspection and moisture readings, so the findings do not rely on the camera alone. We survey loft conversions, pitched roof slopes and ceilings below the roof, and people most frequently book us about damp around roof outlets and upstands and water that travels before it shows.
Flying in London takes more checking than most places: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Before a drone goes up in Hampstead, the address is checked against all of them, and where permission is needed, the flight waits for it.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

What affects the cost of thermal roof surveys
All our prices include VAT. The things that change the price are:
- Height and safe access
- Extensions, dormers and garages with roofs of their own
- Whether you choose the Basic, Standard or Premium Survey
- Chimneys, valleys, parapets and other details
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £400, including VAT.
What we need to know
Some details help us recommend the right survey and price. When you contact us, tell us:
- Where water is showing inside, if it is
- Access details, like a loft hatch or a shared roof
- Photos of the roof, taken safely from ground level or a window
- Your timetable, such as an exchange date
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.
Should I look at the roof myself first?
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Roof by roof
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. Thermal imaging can help show damp patterns around them.
GRP fibreglass roofs
Water can get through cracked GRP into the deck. We combine a visual check of cracks with the thermal images around them.

Airspace, weather and Hampstead roofs
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Hampstead is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
Controlled parking zones are common in London, so mention any permit rules for Hampstead. A roof leak in a hotel or guest house around Hampstead means lost rooms as well as repairs, so it pays to find faults before guests do.

What a thermal roof survey does not cover
In fairness, there are limits to any roof survey:

- The condition of timbers we cannot see
- Structural calculations, which need a structural engineer

Common questions in Hampstead
Are there drone restrictions around Hampstead?
The answer turns on the exact location and the conditions on the day. 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. Each address is checked against all of them before the drone goes up. Before any flight, we check the Drone Safety Map for airspace restrictions. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Does a conservation area affect roof work in Hampstead?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
What insurance do you have?
Our cover is professional indemnity plus public liability.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest, and the report records anything we couldn’t see.
Can you give me structural calculations?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How long does the survey take?
It usually takes an hour or two for a house, rising to roughly 3–4 hours on a commercial building. You will then get the report by email.
Is Hampstead in your area?
Yes, we do. We carry out thermal roof surveys in Hampstead.
Common roof problems in Hampstead
Buyers sometimes want more than a visual look at the roof. A Premium Survey adds thermal imaging, a drone inspection where applicable and a same-day report, which helps when timescales are tight.
It is worth booking a survey if you’ve seen:
- Leaks far from where the stain appears
- Missing or slipped insulation
- Damp around chimneys and parapets
- Moisture around outlets and upstands
If you live in an older home near St John-at-Hampstead church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help.
Questions to ask before booking
- How long they’ve been surveying roofs
- Whether they hold professional indemnity and public liability insurance
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What happens after the report arrives
What we do, step by step
The aim of the visit is simple: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It typically takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In Hampstead, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- If you’re buying, let the agent know when we’re coming
- Keep pets in another room
- Have keys ready for side gates, garages or roof access doors
