Thermal imaging roof survey in Dedworth, Windsor and Maidenhead
Thermal imaging to find moisture and heat loss patterns in a roof for Dedworth and the rest of Windsor and Maidenhead. We survey seven days a week.
- Damp patches with no obvious cause
- Areas of a flat roof that may hold water
- Areas losing heat at the eaves and junctions
When to book a survey in Dedworth
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 suits a purchase that’s moving quickly.
Look out for signs like these:
- Leaks far from where the stain appears
- Possible trapped moisture under a flat roof covering
- Heat escaping through the roof
- Wet areas near outlets and upstands
If you look after a building such as Dedworth Green First School, a view from above covers a wide roof far faster than walking it.
Questions to ask before you book
- Whether the inside of the roof is included
- How much experience they have with roofs like yours
- What’s outside the scope of the survey
- Their drone registration, if they fly one
About our thermal roof survey in Dedworth
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, which is hard to judge by eye. Moisture readings are then used to check what the camera suggests. If you are worried about moisture around outlets and upstands and cold spots on ceilings under the roof, we can find out what’s behind it, whatever the roof.
Older cottages and houses around Dedworth 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. Findings are checked with moisture readings where needed. Results depend on the weather, so the visit is planned around the forecast.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to, and recommendations are put by urgency where it matters.

Questions from Dedworth
How do I find out if my home in Dedworth is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you cover Dedworth?
We do. Every survey there gets the same written report with photos.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. That’s why we check any patterns with moisture readings.
What’s in the survey report?
Written findings with photographs, explaining the condition of the roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
Do you climb onto every roof?
Only where it is safe to do so. We check everything that can safely be seen: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
How much does a thermal roof survey cost?
It’s part of the Premium Survey, from £400. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
Tips from our surveys
From years of surveys, a few habits stand out:
- Leave the roof to people with safe access
- Heat the home normally on the days before
- Keep the report to compare against after any repair
- Talk to us about the weather when booking
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Consider a repeat survey after major work on the roof, when the conditions are suitable.
Drones, thermal imaging and Dedworth roofs
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help. If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying.
Take an older house close to All Saints Church: steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view by drone or thermal camera helps. With St Leonard's Hill about 0.6 miles south, the area around Dedworth has a long history. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition.

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 around your tenants.
What this survey cannot tell you
It’s a careful look at the roof, not the whole story. The main limits are:
- Whether the deck or roof structure is strong enough
- Reliable images in rain, strong wind or on a wet roof surface
- Seeing water directly, as the camera shows temperature, not moisture
If in doubt, phone 07833 053749 or send us an email and we will suggest the right survey. What a survey covers and does not.
What we check
- Commercial roofs
- Pitched roof slopes
- Flat roofs
- Ceilings below the roof
- Insulated roof spaces
- Loft conversions
The survey, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Parking around Dedworth is typically easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- 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.
- A full inspection and thermal imaging are carried out together.
- 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.
Getting ready for the survey
- Leave a clear route to the loft
- Make sure pets are kept safely away
- Mention any parking restrictions on your street
How to book
Not sure which survey you need? The easiest way is to call 07833 053749 or email us and describe the roof and what’s worrying you. We will explain the options and the price.
