Thermal imaging roof survey in Hammer Bottom, Surrey
Independent thermal roof surveys in Hammer Bottom. More than 5,000 surveys completed across London and South East England.
- Missing or slipped insulation
- Stains that keep coming back
- Leaks far from where the stain appears
Different roofs, different checks
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Reflections from shiny surfaces can affect readings, which we allow for.
Felt and asphalt flat roofs
Felt and asphalt roofs often show wet areas as patches that differ from the rest. We check those patches with moisture readings.
About our thermal roof survey in Hammer Bottom
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. This can give an idea of how far water has travelled beneath the membrane, something you can’t normally tell from the surface. Moisture readings are then used to check what the camera suggests. If you’ve noticed missing or slipped insulation and damp patches with no obvious cause, a survey will tell you what’s going on, on loft conversions, insulated roof spaces and commercial roofs alike.
Older buildings in small places like Hammer Bottom may be listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof, 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.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

When to book a survey in Hammer Bottom
Once a leak has been fixed, people often ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain when the conditions on the day are suitable.
Problems we come across frequently include:
- Leaks far from where the stain appears
- Water getting in at parapets and stacks
- Wet areas near outlets and upstands
- Possible trapped moisture under a flat roof covering
Take an older house close to The Parish Church of St Peter: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.
Questions to ask before you book
- What happens after the report arrives
- Whether VAT is added on top
- Whether any drone flown is registered with the CAA
- What they will not be able to tell you
How the survey works
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a small place like Hammer Bottom, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- 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.
How to prepare
- Keep pets inside or away from the areas we are looking at
- Dig out any old roof reports or invoices
- Make a note of anything you’d like us to look at
How to book
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or use the contact form.

What we cannot see
Without opening up the roof, some things stay hidden, so a survey has limits:
- Whether the deck or roof structure is strong enough
- Insulation values or heat loss calculations
- Readings unaffected by sun, shade or reflections

FAQs for Hammer Bottom
Do you cover Hammer Bottom?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Hammer Bottom listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too.
Do you use drones?
Yes, where it applies and safe. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
I live in a flat. Can you survey the roof?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
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.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
Landlords, agents and building managers in Hammer Bottom and across Surrey can book any of our surveys. To discuss a property or a block, call 07833 053749 or send us an email.
Airspace, weather and Hammer Bottom roofs
Older houses across Surrey frequently have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Steep or complicated roofs are frequently hard to see from the ground, which is where photos from the air and thermal images help. Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
Take a building like Woolmer Hill School: a drone or thermal camera can show a large roof in a single visit.
