Thermal roof surveys in Merton and the rest of Oxfordshire. We survey seven days a week.
- Damp around chimneys and parapets
- Stains that keep coming back
- Missing or slipped insulation
Thermal roof survey in Merton: what you get
Thermal imaging is part of our Premium Survey, which starts from £400. It also includes a drone inspection where it applies, a structural analysis and a same-day report. There is an in-person consultation as well, plus a follow-up 12 months later. You can phone 07833 053749 or use the contact form with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We’re often asked to look into heat escaping through the roof and water getting in at parapets and stacks, on insulated roof spaces, loft conversions and commercial roofs.
In a village or hamlet like Merton, roofs can be steep, old and hard to see from the lane. A drone and a thermal camera each give a view you can’t get from the ground. Weather and airspace are checked before the visit. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Merton questions
Is my home in Merton 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, and councils can also use Article 4 directions.
Is Merton within the area you cover?
Yes, Merton is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How much does a thermal roof survey cost?
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.
How long will you be at the property?
Expect it to take roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. You will then get the report by email.
What’s the best way to book?
The quickest way is to phone 07833 053749 or send us an email. Let us know the address and a little about the roof, and we will take it from there. Surveys run seven days a week.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Is thermal imaging good for finding leaks?
It can help narrow down where water may be getting in. Patterns can suggest where trapped water has spread. It is used alongside a close inspection and moisture readings, as the camera alone can’t prove a leak.

Practical tips
You don’t need to be a roofer to help. Here’s what helps most:
- Check from ground level or a window, never by climbing
- Keep the heating on as usual before a heat loss survey
- Use the report as a baseline for later checks
- Tell us where and when you’ve seen damp or stains
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the roof space.
What a thermal roof survey looks like in Merton
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. 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, we check the Drone Safety Map for restrictions before flying.
Boarstall Tower, about 3.7 miles south-east, is one of the historic houses in the wider area around Merton. A drone or thermal survey doesn’t involve any work on the roof, which suits older buildings. If you own one of the older houses in the streets near Church of St Swithin, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

How the survey works
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes about 1–2 hours at a typical home, though large, tall or awkward roofs take more time. Somewhere as small as Merton, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- The roof is inspected visually from safe viewpoints.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Preparing for the visit
- Gather any invoices or paperwork from past roof work
- Make a note of anything you’d like us to look at
- Keep pets in another room
Getting a price

What this survey can’t tell you
It’s a careful look at the roof, not the whole story. Its limits include:
- Whether the deck or roof structure is strong enough
- An energy rating for the building
- Reliable images in rain, strong wind or on a wet roof surface
If you’re not sure which survey you need, ring 07833 053749 or email us and we’ll give you a straight answer. The full list of what we check.
Roofs we survey in Merton
- Flat roofs
- Ceilings below the roof
- Insulated roof spaces
- Pitched roof slopes
- Loft conversions
- Commercial roofs
What we look for on each type of roof
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We combine a visual check of cracks with the thermal images around them.
Single-ply and EPDM roofs
On larger commercial single-ply roofs, thermal imaging can help target moisture readings. It focuses the survey on the areas that matter.
Signs you need a thermal roof survey in Merton
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. The camera helps narrow the search.
These are some of the problems a survey can pick up:
- Areas losing heat at the eaves and junctions
- Areas of a flat roof that may hold water
- Damp patches with no obvious cause
- Damp around roof outlets and upstands
Shop and office owners around Bicester Avenue may find that big, flat commercial roofs are where aerial photos and thermal images help most.
