About our thermal roof survey in Watford
Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where applicable, structural analysis and a report on the same day. An in-person consultation and a 12-month follow-up are included too. You can phone 07833 053749 or send us an email with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey flat roofs, ceilings below the roof and pitched roof slopes, and common reasons people get in touch are damp where roofs meet walls and chimneys and missing or slipped insulation.
A place the size of Watford has flats, offices, shops and schools with flat or low-pitched roofs. On a large flat roof, trapped moisture under the covering can spread a long way from the leak. Aerial photos show the whole roof at once, and anything a thermal image suggests is checked with moisture readings. Blocks, offices and schools often have plant and rooflights that make a roof harder to walk safely.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Heat the home normally on the days before
- Let us know where and when you’ve seen damp or stains
- Clear a path to the loft hatch before we arrive
- Check outlets after heavy rain
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. A follow-up 12 months later is included as well.
Clear outlets and gutters regularly, so water does not sit on the roof. The less water sits, the less can find its way beneath.
Why it is worth a survey now in Watford
Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. In a place with as many rented homes as Watford, small roof faults often turn into tenant complaints. Finding it early, between tenancies if possible, is simpler than dealing with it mid-let.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.
What you get with us
- Insured for professional indemnity and public liability
- We hold a CAA Flyer ID and Operator ID
- An independent view of the roof
- Satisfaction rate of 98%

Do you need a thermal roof survey in Watford?
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there is a clear difference between inside and outside.
It’s worth booking a survey if you’ve seen:
- Thin or uneven insulation in the roof
- Water getting in at parapets and stacks
- Wet areas near outlets and upstands
- Leaks that are hard to trace
If your house is among the older ones in the streets near Church of St Andrew, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Before you book any roof surveyor
- Which limits apply to the survey
- What experience they bring
- What happens after the report arrives
- Whether they hold professional indemnity and public liability insurance
How the survey changes by roof type
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
What a thermal roof survey looks like in Watford
Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. With High Elms Manor about 2.6 miles north, Watford sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you run a hotel or guest house in or near Watford, a roof problem can mean rooms out of use. Take a building like Watford St John's Church of England Primary School: a drone or thermal camera can show a large roof in a single visit.

FAQs for Watford
Is Watford in the area you cover?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is there anything to prepare before you come to Watford?
Clear the way to the loft hatch if there is one, and let us know about any leaks, stains or past repairs. Parking and access details for Watford help us plan the visit.
Will you photograph what you find?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we’ll plan the survey around it.
Can you do a thermal survey in any weather?
Conditions on the day affect the results. A sunny day beforehand, a dry surface and calm air all help. Rain, wind and heavy cloud can weaken the patterns, so we talk through the forecast when booking.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
How we price thermal roof surveys
Survey packages start from £150, inc. VAT. The price for your roof depends on:
- If the survey needs thermal imaging or a drone
- Chimneys, valleys, parapets and other details
- How many separate roofs there are, like extensions, dormers and garages
- Roof area
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
A few details help us point you to the right survey and price. When you contact us, tell us:
- The style of property, from a terrace to a block
- Access details, like a loft hatch or a shared roof
- Where any leaks, stains or damp patches show inside
- When you need the report by

The survey, step by step
The aim of the visit is simple: to see as much of the roof as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit normally takes about 1–2 hours for a house, and longer for a large or complex roof. In Watford, we survey everything from flats and houses to commercial buildings. Each building type brings its own access questions, from shared stairwells to locked plant rooms. Weekday and weekend visits are both available.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Before the survey
- Show us where any leaks or stains appear
- Mention any parking restrictions on your street
- Leave a clear route to the loft
