Thermal imaging roof survey in Stonebridge, Greater London
Thermal roof surveys around Stonebridge, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Areas losing heat at the eaves and junctions
- Wet areas near outlets and upstands
- Wet insulation beneath the membrane
Practical tips
Most of what helps is simple and safe from ground level. Our suggestions:
- Check from the ground or a window, never by climbing
- Clear leaves from outlets and gutters each autumn
- Do not switch the heating off before the visit
- Talk to us about the weather when booking
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. There is a 12-month follow-up too.
Make sure loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the loft space.
How a thermal roof survey works in Stonebridge
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. 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 also look from the loft where we can reach it safely. Common reasons to book are leaks that are hard to trace and gaps in loft insulation, across insulated roof spaces, pitched roof slopes and ceilings below the roof.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. Images are taken to show the roof we’re surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building as you book. The extra view helps most on steep slopes, tall stacks and rear additions.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Stonebridge: your questions answered
Does a conservation area affect roof work in Stonebridge?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is drone flying allowed in Stonebridge?
The answer turns on the exact location and the conditions on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus 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. A small drone cannot fly safely in strong wind or heavy rain, and the rest of the survey doesn’t depend on the drone.
How do I arrange a thermal roof survey in Stonebridge?
To book, phone 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How long does the survey take?
Most surveys take between one and two hours at most homes, with bigger or more complicated roofs taking longer. The report follows by email.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
Does the weather affect a thermal survey?
The weather makes a real difference. A sunny day beforehand, a dry surface and calm air all help. Rain and strong wind can make the images less clear, so we talk through the forecast when booking.
What we look for on each type of roof
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
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
What you can safely check yourself
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
What a thermal roof survey does not cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether the deck or roof structure is strong enough
- The condition of timbers we cannot see
- Insulation values or heat loss calculations
If in doubt, phone 07833 053749 or use the contact form and we will recommend the right survey. What our survey covers.
What we check
- Ceilings below the roof
- Commercial roofs
- Loft conversions
- Flat roofs
- Insulated roof spaces
- Pitched roof slopes
Flying and imaging in Stonebridge
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. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Historic houses such as Pitzhanger Manor, about 2.8 miles south-west, show how far back building in the area around Stonebridge goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Shop and office owners around London Designer Outlet may find that a commercial roof can be photographed from above without anyone walking on it. Controlled parking zones are common in London, so mention any permit rules for Stonebridge, along with any off-street space. A roof leak in a hotel or guest house around Stonebridge means lost rooms as well as repairs, so it pays to find faults before guests do.

What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. A typical survey takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In converted houses and mansion blocks, the loft hatch is often on a shared landing. 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.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- If it isn’t your property yet, arrange access through the agent
- Keep pets inside or away from the areas we’re looking at
- Let us know about any leaks, stains or damp patches you know of
Arrange a survey
