Pirton Thermal Roof Survey
Thermal imaging to find moisture and heat loss patterns in a roof in Pirton, with drones and thermal imaging where they help. Get in touch for a price.
- Moisture around outlets and upstands
- Damp that repairs haven’t cured
- Cold spots on ceilings under the roof
Thermal roof survey in Pirton
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It is not an energy rating or a heat loss calculation. Common reasons to book are cold areas below the roof and areas losing heat at the eaves and junctions, on ceilings below the roof, pitched roof slopes and loft conversions.
Older buildings in small places like Pirton may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it’s a gentle way to see the condition of an old roof, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

Landlords, agents and block managers in Pirton
Landlords and agents in Pirton book surveys as well as homeowners. A report with photos gives you a clear record of the roof.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
Roof by roof
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and can’t be read from them.
Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Shiny surfaces can reflect heat, so we take care reading the images.
Common questions in Pirton
Do you cover Pirton?
Yes, Pirton is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Pirton?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers. We will recommend an engineer if we see signs that call for one.
What conditions are best for thermal imaging?
Conditions on the day have a big effect on what the camera can show. Dry, calm weather after some sun gives the best chance of clear images. We record the conditions in the report, so you know how much weight to give the images.
Do you use drones?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
What can thermal imaging tell me about my roof?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
What this survey can’t tell you
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check
- Insulation values or heat loss calculations
If in doubt, ring 07833 053749 or drop us an email and we’ll suggest the right survey. The full list of what we check.
Roof types and parts we check
- Ceilings below the roof
- Pitched roof slopes
- Flat roofs
- Loft conversions
- Insulated roof spaces
- Commercial roofs
What a survey costs
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- House, block, shop or office
- Chimneys, valleys, parapets and other details
- The roof’s overall size
- How tall the building is and how easy the roof is to see
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both inc. VAT. You will know the exact price before booking.
Booking your survey
If you can, have these to hand when you get in touch:
- Your postcode, so we can check access and travel
- Any stains, drips or damp patches you’ve seen indoors
- Anything about access we should know
- The type of building and roof, like pitched or flat
Unsure which package suits your roof? It is easiest to phone 07833 053749 or send us an email and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.
Thermal roof surveys in Pirton: local notes
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
If you look after a building such as Pirton School, thermal images can show where wet insulation sits under a big flat roof.
Pirton is about 3 miles north-west of Hitchin, in Hertfordshire. Wherever you are in Pirton, we can carry out thermal roof surveys at your property. We cover towns and villages across Hertfordshire, large and small. You can also see our page for Milton Keynes.

What we’re asked to look at in Pirton
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
Things that often lead to a survey include:
- Gaps in loft insulation
- Damp around roof outlets and upstands
- Damp patches with no obvious cause
- Ceilings that feel colder in places
If you live in an older home near Church of St Mary (Church of England), thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Their insurance cover
- What follow-up you get after the report
- How long they’ve been surveying roofs

How the survey works
Once we’ve finished looking, we write up our findings as a written report with photographs, emailed to you. As for time on site, it usually takes about one to two hours for most homes, plus time to check any thermal findings with moisture readings. Somewhere like Pirton needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Keep pets inside or away from the areas we are looking at
- Tell us about any leaks, stains or damp patches you know of
- If you are buying, let the agent know when we are coming
