Common questions in Castle Green
Will parking be an issue for a roof survey in Castle Green?
Parking in Castle Green, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is drone flying allowed in Castle Green?
It depends on the exact address and the weather on the day. Castle Green is about 2 miles from the edge of the flight restriction zone around London City Airport. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. 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. A small drone cannot fly safely in strong wind or a downpour.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Does thermal imaging work on slate and tile roofs?
It can help, but the results are often less clear than on a flat roof. The air space under slates and tiles can hide patterns, so we also look from the loft where it is safe.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so the building owner or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
Can you check my loft insulation with a thermal camera?
Thermal images can suggest where heat is escaping and where insulation may be missing. The survey is not an energy rating or a heat loss calculation, but the images show where improvements may help.
Will the camera show exactly where the water is?
Not directly. It shows temperature, and wet materials often behave differently from dry ones. That’s why we check any patterns with moisture readings.
How a thermal roof survey works in Castle Green
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. Pitched roofs with slates or tiles are often harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. Typical surveys look at damp that repairs haven’t cured and ceilings that feel colder in places, across ceilings below the roof, commercial roofs and loft conversions.
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. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
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 it applies, structural analysis and an in-person consultation.

Checking the roof from the ground
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
Surveys for landlords and agents in Castle Green

For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters.
Thermal roof surveys around Castle Green
Castle Green is about 2 miles from the edge of the flight restriction zone around London City Airport. If the drone is used for your survey, we check the exact boundary for the address before flying. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. 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 Castle Green. Eastbury Manor House lies about 1 mile west, so building around Castle Green goes back a long way. Close-up aerial shots and thermal images let an old roof be checked without anyone disturbing it.
Castle Green is about 1 mile east of Barking, in Greater London. Wherever you are in Castle Green, we can come and survey your property, on a weekday, Saturday or Sunday. We cover towns and villages across Greater London, from the larger towns to small villages. Our London page covers surveys nearby.

What happens on the day
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it’s safe.
- 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.
- The report pairs each thermal image with a photo and explains what it suggests.
Before we arrive
- Tell us about parking before the day
- For flats, make sure roof access has been agreed
- If you’re buying, check with the agent that we can get in
Booking a survey

Tips that help
A little preparation and a few simple habits help. Our tips:
- Talk to us about the weather when booking
- Keep a record of when stains appear
- Clear a path to the loft hatch before we arrive
- Check from the ground or a window, never by climbing
We note the weather and surface conditions, and how they may have affected the results. It helps you judge how firm each finding is.
Consider a repeat survey after major work on the roof in suitable weather.
When to book a survey in Castle Green
People often book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. The camera helps narrow the search.
People typically book a survey when they’ve noticed one of these:
- Damp that repairs haven’t cured
- Patches of heat loss across the roof
- Damp around chimneys and parapets
- Leaks that are hard to trace
For an older house near a landmark such as St John the Divine, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
