Thermal Roof Survey in Ewell
Independent thermal roof surveys in Ewell. More than 5,000 surveys completed across London and South East England.
- Areas losing heat at the eaves and junctions
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Move stored items away from the loft hatch
- Let us know where and when you’ve seen damp or stains
- Use the report as a baseline for later checks
- Check outlets after heavy rain
If you’re buying, the report gives you specific points to raise with the seller or agent. It is your decision how to use it, whether you ask for work before completion or discuss the price.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
Thermal roof surveys for homes and businesses in Ewell
Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. Patterns can suggest where water is trapped under the covering. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we also look from the loft where we can reach it safely. If you’ve noticed areas losing heat at the eaves and junctions and wet insulation beneath the membrane, a survey will tell you what’s going on.
For a town like Ewell, every drone flight starts with a check of the Drone Safety Map, which shows restriction zones around airports and prisons. We fly a sub-250g drone and hold a CAA Flyer ID and Operator ID. Neighbours’ privacy is part of planning every flight. Flights stay below 120 m (400 ft) and within sight, as the open category requires.
After the visit, you get a photo-illustrated written report, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Honest limits
A survey is a close look at the roof, but it cannot do everything. Its limits include:
- Confirming water without moisture readings
- What’s inside walls or under coverings, without opening up
- A structural engineer’s assessment
If in doubt, call 07833 053749 or drop us an email and we will recommend the right survey. What a survey covers and does not.
What we look at
- Commercial roofs
- Ceilings below the roof
- Insulated roof spaces
- Flat roofs
- Pitched roof slopes
- Loft conversions

What else we do in Ewell
What happens on the day
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 between one and two hours on an ordinary house, while a commercial roof takes nearer three to four hours. A typical visit in Ewell begins with the street side of the roof and then moves round the building. Rear gardens and side paths frequently give the best view of extensions and back slopes. Then, if it can be reached safely, we look in the loft.
- 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.
- You get the report the same day, with an in-person consultation to follow.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work

Can I check my roof myself?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book, as it helps us focus the survey.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Different roofs, different checks
GRP fibreglass roofs
Cracks in GRP can let water into the boards beneath. We look at cracks by eye and use the images to see whether there is a pattern around them.
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences often show through. Any patterns are checked with moisture readings.
Drones, thermal imaging and Ewell roofs
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. The wider area around Ewell has a long history of building, with Fitznells Manor about 0.2 miles south-east. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you live in an older home near St Mary's Church, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. Shop and office owners around The Ashley Centre may find that big, flat commercial roofs are where photos from the air and thermal images help most.

Your questions about thermal roof surveys in Ewell
What do I need to do before a survey in Ewell?
Clear the way to the loft hatch if there is one, and let us know about any leaks, stains or past repairs. Parking and access details for Ewell help us plan the visit.
How do I find out if my home in Ewell is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Does the report include photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
What happens next?
The report arrives by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Which survey includes thermal imaging?
Thermal imaging is included in our Premium Survey, from £400. That also includes a full inspection, a drone inspection where it applies, structural analysis and a same-day report.
Do you survey roofs on blocks of flats?
Yes, if whoever owns or manages the building agrees access. We look at the parts we’re given access to.
Will the camera show exactly where the water is?
Thermal imaging shows temperature rather than water. Because wet insulation holds heat for longer, it can show as a different temperature, and moisture readings are used to check it.
What we’re asked to look at in Ewell
Some buyers want extra detail before they commit to a purchase. The Premium Survey brings thermal imaging and a drone inspection where applicable, with a report the same day, which helps when timescales are tight.
Most people get in touch after spotting one of these:
- Gaps in loft insulation
- Wet insulation beneath the membrane
- Damp patches with no obvious cause
- Water that travels before it shows
Anyone responsible for a site like St Clement's Catholic Primary School will know that a drone or thermal camera can show a large roof in a single visit.
What to check before booking
