Colney Heath Thermal Roof Survey
Thermal roof surveys in Colney Heath and the rest of Hertfordshire. We survey on any day of the week.
- Areas losing heat at the eaves and junctions
- Damp where roofs meet walls and chimneys
- Damp that repairs haven’t cured
Useful tips for Colney Heath property owners
You don’t need to be a roofer to help. What helps most:
- Tell us where and when you’ve seen damp or stains
- Make sure the loft can be reached safely
- Do not switch the heating off ahead of the visit
- Check from the ground or a window, never by climbing
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There is a 12-month follow-up too.
Consider a repeat survey after major work on the roof in suitable weather.
Thermal roof surveys for homes and businesses in Colney Heath
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. There’s a 12-month follow-up as well. Common reasons to book are stains that keep coming back and leaks that are hard to trace, on ceilings below the roof, flat roofs and commercial roofs.
Somewhere as small as Colney Heath, older roofs are often steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you cannot get from the ground. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

What affects the price in Colney Heath
We confirm the price for the job before you book. This is what makes a difference:
- The number of roofs, including extensions and garages
- Which survey package you book
- House, block, shop or office
- Any need for thermal images or a drone flight
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.
Getting in touch
If you can, have these to hand when you contact us:
- Pictures from the garden or a window, if you have them
- Dates you’re working to, such as exchange
- Anything about access we should know
- The type of building and roof, like pitched or flat
Most bookings start with a short call: call 07833 053749 or use the contact form. The price is agreed before a date is set.
What we look for on each type of roof
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences often show through. We confirm any patterns with moisture readings.
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. We use the camera and moisture readings to help follow it.
Drones, thermal imaging and Colney Heath roofs
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. About 2.3 miles north-east lies Hatfield House, a reminder of how long the area around Colney Heath has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Take an older house close to Church of St Mark: steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view by drone or thermal camera helps. If you look after a building like Colney Heath Junior Mixed Infant and Nursery School, a view from above covers a wide roof far faster than walking it.
Colney Heath is about 2 miles south-west of Hatfield, in Hertfordshire. Whether the building in Colney Heath is a house, a flat or a commercial unit, the roof can be surveyed. Colney Heath is one of the towns and villages in Hertfordshire we cover. There’s also a page for London.

Signs you need a thermal roof survey in Colney Heath
Unexplained damp is one of the main reasons people ask for thermal imaging. Water can travel under a roof covering or along timbers before it shows inside. The camera helps narrow the search.
Common reasons to book include:
- Leaks that are hard to trace
- Areas of a flat roof that may hold water
- Damp patches with no obvious cause
- Ceilings that feel colder in places
For businesses in and around places such as The Maltings, big, flat commercial roofs are where close-up aerial shots and thermal images help most.
Questions to ask before booking
- When you’ll get the report
- Is VAT included in the price?
- Will the report include photos?
- What they will not be able to tell you

The survey, step by step
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes between one and two hours for most houses, while a commercial roof takes nearer three to four hours. In a small place like Colney Heath, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Getting ready for the survey
- Show us where any leaks or stains appear
- If you’re buying, let the agent know when we’re coming
- Unlock side gates and any roof access doors

Questions from Colney Heath
Is my home in Colney Heath listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover smaller places like Colney Heath?
Yes, Colney Heath is on our map. Villages and rural addresses get the same survey as a town house.
What happens after the survey?
The report arrives by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. The patterns can suggest wet insulation, gaps in insulation or heat escaping. Findings are checked with moisture readings.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
