Thermal Roof Survey in Northfleet
Thermal roof surveys in Northfleet, with over 20 years’ experience behind it. Every survey ends with a written report and photos.
- Leaks that are hard to trace
- Areas of a flat roof that may hold water
- Damp patches with no obvious cause
What we do, step by step
After the inspection, everything we found is written up in a report with photographs, emailed to you. On timing, it typically takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. In Northfleet, parking is rarely complicated, though it helps to know about driveways or restrictions. The inspection covers whatever is safely visible from outside, from windows and from the loft space, and from the roof itself where it’s safe.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work

Advice
Thermal roof surveys for homes and businesses in Northfleet
We present each thermal image next to a normal photo of the same area, so it’s easy to see which part of the roof each one shows. 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 is a 12-month follow-up as well. We’re often asked to look into wet insulation beneath the membrane and leaks far from where the stain appears, across pitched roof slopes, insulated roof spaces and loft conversions.
In a town like Northfleet, the roofs that are hardest to see are frequently on taller buildings, steep slopes or the backs of terraces. Close-up drone photos and thermal images show what binoculars from the pavement cannot. Each needs the right weather, so the date is set with the forecast in mind. Rear slopes over back additions are a common example, as they’re rarely visible from the street.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What happens if roof problems are left?
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. Extensions and dormers on homes around Northfleet frequently hide the first signs of trouble at their joints with the main roof. Left for a few seasons, it can spoil plaster, skirting and flooring inside.
Prices quoted always include VAT, and the written report is part of the package. Our price is from £400, including VAT. Where your roof sits in the range depends on its size, height and access.

Do you need a thermal roof survey in Northfleet?
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Signs worth acting on include:
- Moisture around outlets and upstands
- Water getting in at parapets and stacks
- Leaks that are hard to trace
- Areas of a flat roof that may hold water
Cobham College lies about 3.7 miles south-east, so building around Northfleet goes back a long way. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings.

Drones, thermal imaging and Northfleet roofs
Northfleet lies within about 3 miles of the sea, and wind off the sea can be strong. Calm, dry conditions after a sunny day suit thermal imaging best, so the visit is planned around the forecast. Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Steep or complicated roofs are frequently hard to see from the ground, which is where close-up aerial shots and thermal images help.
Take an older house close to Church of All Saints: thin or patchy insulation under an old roof frequently shows up clearly on a thermal image. For site and facilities teams at buildings such as Northfleet Technology College, thermal images can show where wet insulation sits under a big flat roof.

Honest limits
Before you book, it is worth knowing what a survey will not do:
- The condition of timbers we cannot see
- Proving moisture from the images alone
- An energy rating for the building

What this survey covers
- Pitched roof slopes
- Insulated roof spaces
- Ceilings below the roof
- Flat roofs
- Commercial roofs
- Loft conversions
Different roofs, different checks
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. Thermal imaging helps suggest where it is, when the conditions allow.
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We back up what the camera shows with a look in the loft where we can.
FAQs for Northfleet
Do you cover Northfleet?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
How do I find out if my home in Northfleet is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Do you take photos of the roof?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What does a thermal roof survey show?
The images show how warm or cool each part of the surface is. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Is thermal imaging useful on pitched roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Checking the roof from the ground
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
It’s useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when booking.
