Thermal roof survey in Blacknest
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, something you can’t usually tell from the surface. Moisture readings are then used to check what the camera suggests. Typical surveys look at damp around chimneys and parapets and patches of heat loss across the roof, across commercial roofs, loft conversions and insulated roof spaces.
Some older homes in villages like Blacknest are listed or in a conservation area. A look from the air or with a thermal camera does not 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.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

When to book a survey in Blacknest
Some owners book because the rooms under the roof feel cold. Gaps in loft insulation and poorly insulated roof areas can show up on the camera, particularly when there is a clear difference between inside and outside.
These are some of the problems a survey can pick up:
- Ceilings that feel colder in places
- Thin or uneven insulation in the roof
- Areas of a flat roof that may hold water
- Water getting in at parapets and stacks
For any home in Blacknest, it is the small, early fault that is cheapest to put right.
What to check before booking
- Their report turnaround times
- Their track record with similar roofs
- Whether you can ask questions once you have the report
- Whether VAT is in the quoted price
Honest limits
No survey can tell you everything, and it’s better to know them up front. Keep these in mind:
- Proving moisture from the images alone
- Structural calculations, which need a structural engineer
- Readings unaffected by sun, shade or reflections

Roof types and parts we check
- Loft conversions
- Insulated roof spaces
- Flat roofs
- Ceilings below the roof
- Commercial roofs
- Pitched roof slopes
Tips from our surveys
These tips come from what we see on roofs every week:
- Do not switch the heating off ahead of the visit
- Keep the report to compare against after any repair
- Clear leaves from outlets and gutters each autumn
- Let us know where and when you’ve seen damp or stains
Premium Surveys include an in-person consultation, so you can go through the images with us. A follow-up 12 months later is included as well.
Make sure loft insulation covers the whole area and hasn’t been disturbed. Gaps often appear after work in the loft.
How the survey works
Safety comes first on every visit. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. Most visits take roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Older rural homes like those around Blacknest can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- You tell us about the roof and any damp, leaks or cold rooms.
- 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.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Let us know about any leaks, stains or damp patches you know of
- Mention any parking restrictions on your street
- Make a note of anything you’d like us to look at

Blacknest questions
How do I find out if my home in Blacknest is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.

Thermal roof surveys in Blacknest: local notes
Thatch survives on some older buildings in Hampshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
Historic houses like Farnham Castle, about 4.1 miles north-east, show how far back building around Blacknest goes. 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.
Blacknest is about 4 miles south-west of Farnham, in Hampshire. We cover Blacknest and the rest of Hampshire. Across Hampshire, we cover Blacknest and the places around it. For surveys nearby, see our Guildford page.

Why it is worth a survey now in Blacknest
Buyers get extra information from thermal images that the eye can miss. Hidden problems found before exchange can be raised with the seller or agent. In a place like Blacknest, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
