Picketts Lock Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof for Picketts Lock and the rest of Greater London. We survey seven days a week.
- Gaps in loft insulation
- Damp around roof outlets and upstands
- Areas of a flat roof that may hold water
What affects the cost of thermal roof surveys
Survey packages start from £150, with VAT included. The price for your roof depends on:
- House, block, shop or office
- The shape of the roof and its details
- How many separate roofs there are, such as extensions, dormers and garages
- Which survey package you book
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all with VAT included. What your roof costs depends on its size, access and what you want to find out.
What we need to know
A little information up front helps. It helps to include:
- Your timetable, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
- The reason for the survey, like buying, a leak or storm damage
Booking is simple: just phone 07833 053749 or send us an email and give us some details about the property and we will explain which survey suits. We confirm the price before anything is booked.
Thermal roof surveys for homes and businesses in Picketts Lock
Thermal imaging is a useful tool, but it has limits. It shows surface temperature, and things like sun, shade, reflections and wind all affect the readings. That’s 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 cannot be confirmed, the report suggests a next step. Common reasons to book are damp that repairs haven’t cured and missing or slipped insulation, on pitched roof slopes, ceilings below the roof and insulated roof spaces.
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. Weather on the day decides whether it goes ahead, in Picketts Lock as anywhere. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Airspace, weather and Picketts Lock roofs
Bruce Castle, about 2.6 miles south-west, is one of the historic houses in the wider area around Picketts Lock. 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, and the council can say whether a home is in a conservation area. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
If you look after a building such as Delta Primary School, thermal images can show where wet insulation sits under a big flat roof. If you own one of the older houses in the streets near All Saints' Church, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from the air or with a thermal camera helps.

An agent can book and manage the survey for a landlord. Access is agreed with the tenant ahead of time.
What we do, step by step
Once we’ve finished looking, we write up our findings in a report with photographs, emailed to you. As for time on site, it normally takes an hour or two at a typical home, and more on a big or complicated roof. Surveys in Picketts Lock can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- Jot down any questions you want answered
- For flats, make sure roof access has been agreed
- If it isn’t your property yet, arrange access through the agent

Common questions in Picketts Lock
Will parking be an issue for a roof survey in Picketts Lock?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
How do I find out if my home in Picketts Lock is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. We do not give energy ratings or heat loss calculations, but the images show where improvements may help.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. We’ll talk about access when you book.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days as you book.
Is thermal imaging good for finding leaks?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. Where it can’t be pinned down, the report suggests a next step, such as electronic leak detection.
How do I book a survey in Picketts Lock?
It is easiest to call 07833 053749 or email us. Let us know the address and a little about the roof, and we will take it from there. We survey on weekdays, Saturdays and Sundays.
Before and after the survey
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Don’t climb onto the roof to look for leaks yourself
- Let us know where and when you’ve seen damp or stains
- Clear a path to the loft hatch before we arrive
- Heat the home normally on the days before
Buyers can use the findings when talking to the seller or agent. It’s your decision how to use it, whether that’s asking for work or discussing the price.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
What you can safely check yourself
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when booking, as it helps us focus the survey.
When to book a survey in Picketts Lock
Once a leak has been fixed, people frequently ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain, given suitable conditions on the day.
It is worth booking a survey if you’ve seen:
- Areas losing heat at the eaves and junctions
- Cold spots on ceilings under the roof
- Water getting in at parapets and stacks
- Thin or uneven insulation in the roof
If you look after a shop, office or commercial unit, for instance near Edmonton Green Shopping Centre, thermal images can show trapped moisture across a wide commercial roof.
Choosing a roof surveyor
- How long they’ve been surveying roofs
- Will the report include photos?
- What the survey will not cover
- Which viewpoints they use to see the roof
