Thermal roof survey in Blackwater
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, something you cannot normally tell from the surface. We then check those areas with moisture readings. Typical surveys look at gaps in loft insulation and wet insulation beneath the membrane, across loft conversions, pitched roof slopes and flat roofs.
Some older homes in villages like Blackwater are listed or in a conservation area. A look from the air or with a thermal camera doesn’t touch the roof, which suits a building where any change needs care, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What affects the cost of thermal roof surveys
Prices vary from roof to roof, for these reasons:
- Which survey package you book
- Extensions, dormers and garages with roofs of their own
- Building height and the viewpoints available
- Roof area
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
Getting in touch
Getting the details right at the start saves time. It’s useful to include:
- Pictures from the garden or a window, if you have them
- Your postcode, so we can check access and travel
- Any deadline, such as an exchange date
- What kind of property and roof it is
For a price for thermal roof surveys in Blackwater, phone 07833 053749 or email us. Some details about the property and the roof help us price the survey accurately.
Different roofs, different checks
Felt and asphalt flat roofs
Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, given suitable conditions on the day.
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. That makes the survey more focused.
Why it’s worth a survey now in Blackwater
Before replacing a large flat roof, it’s useful to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you commit. Older cottages and farmhouses around Blackwater can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.

What else we do in Blackwater
How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two for a house, and longer for a large or complex roof. For a village or hamlet like Blackwater, the journey is planned beforehand: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- 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 we arrive
- Make sure pets are kept safely away
- Point out any leaks or damp patches
- Let us know about parking near the property

DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Airspace, weather and Blackwater roofs
Some villages on the Isle of Wight still have thatched roofs, and sea air and wind reach every part of the island. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
Take an older house close to St. Olave's Church: tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Gatcombe House lies about 1.2 miles south-west, so building around Blackwater goes back a long way. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager doesn’t touch the roof itself. Anyone responsible for a site like Christ The King College will know that a view from above covers a wide roof far faster than walking it.

FAQs for Blackwater
Does a conservation area affect roof work in Blackwater?
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.
Will you come out to Blackwater?
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 you book.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Can a thermal camera see water?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep the report to compare against after any repair
- Photograph damp patches with the date
- Remember the conditions on the day affect the results
- Let us know where and when you’ve seen damp or stains
If the images suggest moisture that can’t be confirmed, we’ll say what would help next, for example electronic leak detection or a roofer opening up a small section.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
