Petts Wood Thermal Roof Survey
Thermal roof surveys for homes and businesses in Petts Wood. More than 5,000 surveys completed across London and South East England.
- Patches of heat loss across the roof
- Stains that keep coming back
- Moisture around outlets and upstands
How a thermal roof survey works in Petts Wood
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves frequently show up as temperature differences. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It isn’t an energy rating or a heat loss calculation. We survey ceilings below the roof, flat roofs and insulated roof spaces, and the problems we’re asked to look at most are areas losing heat at the eaves and junctions and possible trapped moisture under a flat roof covering.
London airspace is busy and tightly controlled: 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. Every address in Petts Wood is checked before any drone flight, and where permission is needed, the flight waits for it.
The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to.

Signs you need a thermal roof survey in Petts Wood
Once a leak has been fixed, people often ask whether the roof is still wet. Thermal images and moisture readings can suggest whether moisture is still trapped, given suitable conditions on the day.
Common reasons to book include:
- Damp around chimneys and parapets
- Areas losing heat at the eaves and junctions
- Wet areas near outlets and upstands
- Missing or slipped insulation
For site and facilities teams at buildings such as Crofton Junior School, thermal images can show where wet insulation sits under a big flat roof.
Before you book any roof surveyor
- Their report turnaround times
- How much experience they have with roofs like yours
- Is there a chance to talk the report through?
- What exactly goes into their report
Tips from our surveys
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Some tips:
- Remember the conditions on the day affect the results
- Note where damp appears and after what weather
- Check from ground level or a window, never by climbing
- Photograph damp patches with the date
If you are buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether that is asking for work or discussing the price.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
When you need someone else
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Reliable images in rain, strong wind or on a wet roof surface
- The condition of timbers we can’t see
- Seeing water directly, as the camera shows temperature, not moisture
If in doubt, ring 07833 053749 or email us and we’ll recommend the right survey before booking. What our survey covers.
What we look at
- Ceilings below the roof
- Insulated roof spaces
- Loft conversions
- Commercial roofs
- Pitched roof slopes
- Flat roofs
Why it’s worth a survey now in Petts Wood
Before replacing a large flat roof, it helps to know how much of it is actually wet. Images backed by moisture readings show where problems seem to be before you spend. In Petts Wood, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
All our prices include VAT. Prices start from £400, including VAT. We confirm the price for your survey before booking.

Thermal roof surveys around Petts Wood
About 2.6 miles north-west lies Bromley Palace, a reminder of how long the area around Petts Wood has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
Parking in Petts Wood, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway as you book, as a space near the door can’t be promised. If you run a business near The Mall, large commercial roofs are often easiest to see by drone or thermal camera.

How the survey works
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take about one to two hours for most houses, while a commercial roof takes nearer three to four hours. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- 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.
- You get the report the same day, with an in-person consultation to follow.
Getting ready for the survey
- Leave side gates unlocked
- Leave a clear route to the loft
- Have any paperwork from past roof work to hand

Petts Wood: your questions answered
Does a conservation area affect roof work in Petts Wood?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is drone flying allowed in Petts Wood?
That depends on where the roof is and on the weather. 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. 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, including zones around airports and prisons. High wind or heavy rain also stops a small drone flying.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Can you check my loft insulation with a thermal camera?
Gaps and thin areas of insulation can show up on the camera. The difference is clearest when the building is heated and it’s colder outside. We look from the loft as well, where there is safe access.
Can you survey at the weekend?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or use the contact form.
How fast do I get the report?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
How do I book a survey in Petts Wood?
The quickest way is to call 07833 053749 or send us an email. Give us the address and a few details about the roof, and we will take it from there. We survey on weekdays and at weekends.

Checking the roof from ground level
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
