Thermal roof survey in Letchmore Heath: what you get
Thermal imaging is a useful tool, but it has limits. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. If a finding cannot be confirmed, the report suggests a next step. If you’re worried about gaps in loft insulation and wet insulation beneath the membrane, a survey will tell you what’s going on, on pitched roof slopes, commercial roofs and flat roofs alike.
In a small place like Letchmore Heath, open ground can mean strong wind. A small drone cannot fly safely in strong wind or a downpour, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. A change in the forecast can mean moving the visit to another day.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Roof by roof
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. Thermal imaging can suggest where that may be happening.
Loft insulation
In the roof space, the camera can pick up gaps and thin areas of insulation. We look where there is safe access.
Questions from Letchmore Heath
Is my home in Letchmore Heath listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is 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.
Can you fly a drone over a roof in Letchmore Heath?
The answer turns on the exact location and the conditions on the day. Elstree Aerodrome is about 1 mile away, so we check the Drone Safety Map for restrictions before any flight. Strong wind or a downpour also stops a small drone flying, though the rest of the survey goes ahead either way.
What happens next?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you walk on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where applicable, and the report records anything we couldn’t see.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. The survey isn’t an energy rating or a heat loss calculation, but the report shows where to look more closely.
Will the camera show exactly where the water is?
Not directly. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
What we do, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. If you have questions on the day, just ask. Somewhere as small as Letchmore Heath, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- 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.
- You get a report with thermal images, photographs and our recommendations.
Before the survey
- Let us know about parking near the property
- Have any questions written down, so nothing gets missed
- Point out any leaks or damp patches

How we price thermal roof surveys
Survey packages start from £150, inc. VAT. What you pay for your roof depends on:
- Which survey package you book
- Extensions, dormers and garages with roofs of their own
- Commercial roofs and larger buildings
- How tall the building is and how easy the roof is to see
For a price for your roof in Letchmore Heath, call 07833 053749 or drop us an email with the address and some details. We’ll confirm the figure before booking.
What to tell us when you contact us
These details help when you get in touch:
- What’s prompted the survey
- Pictures of the roof from a safe spot, if you have them
- Your postcode, so we can check access and travel
- The kind of building and roof involved
Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or send us an email.
Useful tips for Letchmore Heath property owners
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Heat the home normally on the days before
- Keep outlets and gutters clear to stop water sitting
- Keep dated photos of any marks on ceilings
- Keep the report to compare against after any repair
Once we have been, the thermal images, photos and readings go into a single 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. Once water gets under a membrane, it can travel far before it appears inside.
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Why it is worth a survey now in Letchmore Heath
A damp patch that keeps coming back typically has a cause that hasn’t been found. Thermal imaging with moisture readings can help narrow it down, instead of trying repair after repair. In a small place like Letchmore Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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.

Drones, thermal imaging and Letchmore Heath roofs
About 3.5 miles north-west lies High Elms Manor, a reminder of how long the area around Letchmore Heath has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Letchmore Heath is about 1 mile from Elstree Aerodrome. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
For site and facilities teams at buildings such as Fair Field Junior School, a view from above covers a wide roof far faster than walking it. If you look after a shop, office or commercial unit, for instance near Harlequin Centre, big, flat commercial roofs are where aerial photos and thermal images help most. The streets around a church like Church of St John the Baptist are often among the oldest in a place, and if your home is one of the older ones nearby, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
