About our thermal roof survey in Old Malden
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. We survey ceilings below the roof, insulated roof spaces and flat roofs, and common reasons people get in touch are wet insulation beneath the membrane and damp patches with no obvious cause.
Older cottages and houses around Old Malden may have little insulation, and some have extensions with their own roofs. A thermal image can show where heat is escaping or where moisture may be trapped, and drone photos show the roof surfaces themselves. Anything that looks like moisture is checked with a meter. Results depend on the weather, so the visit is planned around the forecast.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

Flying and imaging in Old Malden
If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying. 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. Steep or complicated roofs are frequently hard to see from ground level, which is where aerial photos and thermal images help.
For businesses in and around places such as Bentall Centre, a commercial roof can be photographed from above without anyone walking on it. Take an older house close to Parish Church of St Mary the Virgin: thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Old Malden is about 2 miles north-west of Ewell, in Surrey. We visit Old Malden as part of our work across Surrey, for houses, flats and commercial buildings. Our Surrey coverage includes Old Malden. We also survey roofs in London.

Different roofs, different checks
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
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.
What happens on the day
The aim of the visit is simple: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes about one to two hours at most homes, and longer for a large or complex roof. Homes around Old Malden frequently have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- 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.
- Each image is set beside a normal photo and explained in the report.
Before we arrive
- Show us where any leaks or stains appear
- If you’re buying, let the agent know when we’re coming
- Mention any parking restrictions on your street
Booking a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To get started, ring 07833 053749 or send us an email.

Your questions about thermal roof surveys in Old Malden
Does a conservation area affect roof work in Old Malden?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Old Malden?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
How do I book a survey in Old Malden?
To arrange a survey, phone 07833 053749 or use the contact form and tell us the address and what you need to know. We’ll confirm the price and find a day that suits.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. We check the parts we are given access to, and the report makes that clear.
Can you check my loft insulation with a thermal camera?
It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
Common roof problems in Old Malden
On big commercial and residential flat roofs, thermal imaging helps owners plan. Patterns can point to wet areas and show which parts look sound, so moisture readings can be targeted.
Signs worth acting on include:
- Moisture around outlets and upstands
- Wet insulation beneath the membrane
- Gaps in loft insulation
- Ceilings that feel colder in places
Take a building like Knollmead Primary School: a drone or thermal camera can show a large roof in a single visit.
Questions to ask before you book
- What happens after the report arrives
- Which limits apply to the survey
- How much experience they have with roofs like yours
- Whether you get a written report with photos
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which can make access easier.
Landlords, agents and building managers in Old Malden and across Surrey can book any of our surveys. To discuss a property or a block, call 07833 053749 or drop us an email.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check from the ground or a window, never by climbing
- File the images with your roof records
- Make sure the loft can be reached safely
- Tell us where and when you’ve seen damp or stains
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it’s easy to find each area on the roof.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
