How a thermal roof survey works in Colthrop
A thermal survey isn’t a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. That is why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they do not. Where something cannot be confirmed, we say what would help next. Typical surveys look at water getting in at parapets and stacks and damp that repairs haven’t cured, on pitched roof slopes, flat roofs and loft conversions.
Some older homes in villages like Colthrop are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, which suits a building where any change needs care. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
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.

Why act early in Colthrop
Heat lost through a roof costs money every winter. Thermal images can show where insulation is missing or has slipped, so improvements can go where they’re needed. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we will tell you which fits.

Flying and imaging in Colthrop
Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. Historic houses such as Shaw House, about 3.5 miles west, show how far back building in the area around Colthrop goes. Older homes in the wider area frequently 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.
Take a building like Francis Baily Primary School: a view from above covers a wide roof far faster than walking it.

What a survey costs
Survey packages start from £150, including VAT. The price for your roof depends on:
- Building height and the viewpoints available
- Features like valleys, chimneys, dormers and parapets
- Whether you choose the Basic, Standard or Premium Survey
- The type of building, from a house to a block or an office
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Booking your survey
These details help when you get in touch:
- Whether there’s a loft hatch, a shared roof or tricky access
- Photos of the roof, taken safely from ground level or a window
- Any stains, drips or damp patches you’ve seen indoors
- Why you want a survey: buying, a leak, a storm or new work
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or send us an email when you are ready.
Do you need a thermal roof survey in Colthrop?
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so moisture readings can be targeted.
Common reasons to book include:
- Cold areas below the roof
- Missing or slipped insulation
- Areas losing heat at the eaves and junctions
- Water getting in at parapets and stacks
The streets around a church such as St Mary's Church are frequently among the oldest in a place, and if yours is one of the older homes nearby, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

How the survey changes by roof type
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, given suitable conditions on the day.
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there’s a pattern around them.
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. Notes and photographs go into the written report. It typically takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a small place like Colthrop, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Show us where any leaks or stains appear
- Keep pets inside or away from the areas we are looking at
- Have any questions written down, so nothing gets missed

Questions from Colthrop
Do you carry out roof surveys in Colthrop?
Yes. We work right across London and the South East, and Colthrop is part of that. You can ring 07833 053749 or send us an email with the address and a few details.
Is my home in Colthrop listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Does thermal imaging work on slate and tile roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.
What will the report tell me?
Written findings with photographs, covering the condition of the roof, the defects we found and what we recommend, in order of urgency where relevant. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Will you photograph what you find?
Yes. We photograph the roof as we go, and they go into the written report.
Do you climb onto every roof?
Not always. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where it applies.
