Thermal roof surveys for homes and businesses in Bull's Green
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we also look from the loft where we can reach it safely. Typical surveys look at water getting in at parapets and stacks and areas of a flat roof that may hold water, across commercial roofs, insulated roof spaces and pitched roof slopes.
Some older homes in villages like Bull's Green 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.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Questions from Bull's Green
How do I find out if my home in Bull's Green is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Bull's Green?
Yes. Our area covers London and the South East, and Bull's Green is part of that. Just call 07833 053749 or send us an email and tell us about the property, and we will talk through which survey suits.
Is thermal imaging included in your surveys?
Our Premium Survey, from £400, includes thermal imaging. You also get an in-person consultation and a 12-month follow-up. For bigger commercial roofs, we quote on size.
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 use a thermal camera on a sloping roof?
It can be useful, though pitched roofs are normally harder to read. The air space under slates and tiles can hide patterns, so we combine it with an inspection from the loft where there’s safe access.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
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.
How the survey changes by roof type
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. That makes the survey more focused.
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. The camera can help show damp around these junctions.
What a thermal roof survey doesn’t cover
A survey is a close look at the roof, but it cannot do everything. Its limits include:
- Whether the deck or roof structure is strong enough
- The condition of timbers we cannot see
- Clear results when the conditions on the day are poor
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we’ll tell you before booking. What a survey covers and does not.

What we do, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. The survey itself takes about one to two hours for most houses, and about three to four hours for a commercial roof. Somewhere like Bull's Green needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- 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.
Preparing for the visit
- Keep pets out of the way during the survey
- Unlock side gates and any roof access doors
- Mention any parking restrictions on your street

Common roof problems in Bull's Green
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
Typical things we’re asked to look at include:
- Heat escaping through the roof
- Damp around chimneys and parapets
- Wet areas near outlets and upstands
- Stains that keep coming back
If you run a business near Howard Centre, large commercial roofs are often easiest to see from above or with a thermal imager.
Questions to ask before booking

- When you’ll get the report
- How much experience they have with roofs like yours
- What follow-up you get after the report

Tips that help
A little preparation and a few simple habits help. Our tips:
- Don’t climb onto the roof to look for leaks yourself
- Remember the conditions on the day affect the results
- Move stored items away from the loft hatch
- Keep the report to compare against after any repair
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it is easy to find each area on the roof.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
