Friar's Wash Thermal Roof Survey
Wondering about the roof at a property in Friar's Wash? We carry out thermal roof surveys in Friar's Wash and across Hertfordshire.

What affects the cost of thermal roof surveys
Prices vary from roof to roof, for these reasons:
- The package you choose: Basic, Standard or Premium
- How big the roof is
- The number of roofs, including extensions and garages
- Chimneys, valleys, parapets and other details
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
What to tell us when you get in touch
A little information up front helps. It’s useful to include:
- Dates you’re working to, like exchange
- The address and postcode of the property
- Any marks or damp showing indoors
- The reason for the survey, such as buying, a leak or storm damage
To arrange a survey, call 07833 053749 or email us with the address and what you’d like to know about the roof. We’ll confirm the price before booking.
Thermal roof surveys for homes and businesses in Friar's Wash
A thermal imaging roof survey uses a thermal camera to show differences in surface temperature across a roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera does not see water itself, so findings are checked with moisture readings. Thermal imaging is included in our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. We survey ceilings below the roof, loft conversions and pitched roof slopes, and the problems we’re asked to look at most are leaks that are hard to trace and damp that repairs haven’t cured.
Somewhere as small as Friar's Wash, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report records the roof as we found it on the day. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

Useful tips for Friar's Wash property owners
Over many surveys, some simple habits stand out:
- Talk to us about the weather when booking
- Don’t climb onto the roof to look for leaks yourself
- Note where damp appears and after what weather
- Keep the report to compare against after any repair
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, with our recommendations. With a Premium Survey, you get the report the same day.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
What we cannot see
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Reliable images in rain, strong wind or on a wet roof surface
- A formal energy assessment
- Hidden layers that need to be opened up to check
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you. What a survey covers and does not.
What we look at
- Pitched roof slopes
- Loft conversions
- Commercial roofs
- Flat roofs
- Insulated roof spaces
- Ceilings below the roof
Airspace, weather and Friar's Wash roofs
The flight restriction zone around Luton Airport comes within about 2 miles of Friar's Wash. If your survey includes the drone, we check the exact boundary for the address before flying. Historic houses like Childwickbury Manor, about 4.5 miles south-east, show how far back building in the area around Friar's Wash goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof.
If you run a business near The Mall Luton, thermal images can show trapped moisture across a wide commercial roof. Anyone responsible for a site like Flamstead Village School will know that thermal images can show where wet insulation sits under a big flat roof. If yours is one of the older homes in the streets near Church of St Leonard, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.

Common questions in Friar's Wash
Does a conservation area affect roof work in Friar's Wash?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover smaller places like Friar's Wash?
Yes. Friar's Wash is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you survey on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
How do I arrange a thermal roof survey in Friar's Wash?
Just ring 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
Is it a structural engineer’s report?
No. We’re roof surveyors, not structural engineers, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Can a thermal survey trace a roof leak?
It frequently helps show where to look. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings because the camera cannot confirm water on its own.
What we do, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take between one and two hours on an ordinary house, with bigger or more complicated roofs taking longer. Cottages and farmhouses around Friar's Wash often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
How to prepare
- Make sure pets are kept safely away
- Jot down any questions you want answered
- For a flat or shared roof, check access with the freeholder or managing agent
