Thermal roof survey in Shenley
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so we check what it shows 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 commercial roofs, flat roofs and pitched roof slopes, and the problems we are asked to look at most are cold areas below the roof and water that travels before it shows.
Around Shenley, a good many roofs are low enough to see partly from the garden or the street. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day, as calm, dry conditions suit both. Close-up images frequently show wear on ridges, verges and flashings that cannot be judged properly from ground level.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. You will see the good as well as the bad.

Roof by roof
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. The camera can give clues to where it is sitting, when the conditions allow.
Loft insulation
Heat loss shows most clearly when it’s warm inside and colder outside. Our report notes how the conditions affected the images.
What happens if roof problems are left?
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Blocked gutters on homes around Shenley overflow and soak walls. Dealing with the cause is simple; drying out a wall is not.
Our price is from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.

Useful tips for Shenley property owners
Over many surveys, some simple habits stand out:
- Remember the conditions on the day affect the results
- Don’t switch the heating off ahead of the visit
- Keep outlets and gutters clear to stop water sitting
- Check the loft can be reached safely
We note the weather and surface conditions, and how they may have affected the results. That way you know how much weight to give each finding.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.
Common roof problems in Shenley
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 when the conditions on the day are suitable.
Most people get in touch when they’ve noticed one of these:
- Stains that keep coming back
- Heat escaping through the roof
- Cold spots on ceilings under the roof
- Possible trapped moisture under a flat roof covering
Take an older house close to Church of St Martin: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Questions to ask before booking
- Whether the inside of the roof is included
- Which parts of the roof they’ll actually see
- Their report turnaround times
- What exactly goes into their report
What a thermal roof survey doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before booking. Keep these in mind:
- A structural engineer’s assessment
- Insulation values or heat loss calculations
- Reliable images in rain, strong wind or on a wet roof surface
If you are not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before booking. What our survey covers.

How the survey works
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 about 1–2 hours at a typical home, and more on a big or complicated roof. Some parts of a survey depend on the weather, so a visit to Shenley is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- 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.
Before the survey
- If it isn’t your property yet, arrange access through the agent
- Keep pets in another room
- Agree roof access with the managing agent if it is shared

On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.

Your questions about thermal roof surveys in Shenley
Is my home in Shenley listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 Shenley?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, but we check each finding with moisture readings.
Do I need to be at home?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
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, which we then check with moisture readings.
How quickly is the report sent?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What’s the best way to book?
