Thermal roof survey in Cow Roast
Thermal imaging is frequently most useful on flat roofs, from small extensions to large commercial roofs. 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. If you are worried about areas of a flat roof that may hold water and stains that keep coming back, we can find out what’s behind it.
Some older homes in villages like Cow Roast are 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. Check with the council before planning any work on a listed building or one in a conservation area.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Your questions about thermal roof surveys in Cow Roast
Is my home in Cow Roast listed or in a conservation area?
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.
Is Cow Roast within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
When does the report arrive?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
Is this an asbestos survey?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
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.
How does a thermal imaging roof survey work?
It records surface temperature across the roof. Differences can suggest wet areas, missing insulation or heat loss, and we check them with moisture readings.
Useful tips for Cow Roast property owners
There is plenty you can do without going near the roof. Here’s what helps most:
- Make sure the loft can be reached safely
- Keep the report to compare against after any repair
- Ask us about the forecast if rain is expected
- Photograph damp patches with the date
After the visit, we put the thermal images, photos and moisture readings into one report. We explain what each image may mean, alongside what we recommend. With a Premium Survey, you get the report the same day.
After repairs or a new covering, a later survey can confirm things are dry in suitable weather.
Checking the roof from ground level
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
How it works
After the inspection, everything we found is written up as a written report with photos. As for time on site, it usually takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. For a village or hamlet like Cow Roast, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Check we can get to the back of the property
- Mention any parking restrictions on your street
- Leave a clear route to the loft
Getting a price
Photos help, if you have them. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or email us.

Airspace, weather and Cow Roast roofs
The wider area around Cow Roast has a long history of building, with Cholesbury Manor House about 2.7 miles south-west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Steep or complicated roofs are frequently hard to see from ground level, which is where aerial photos and thermal images help.
Anyone responsible for a site like Tring School will know that a view from above covers a wide roof far faster than walking it. If yours is one of the older homes in the streets near Church of St Bartholomew (church of England), tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

Surveys for landlords and agents in Cow Roast
Letting agents frequently book on a landlord’s behalf. We agree a time with the tenant beforehand.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Different roofs, different checks
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. Thermal images can show where it has been pushed aside.
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
How we price thermal roof surveys
When we price a survey, we consider:
- If the survey needs thermal imaging or a drone
- Roof area
- The height of the building and how the roof can be seen safely
- The package you choose: Basic, Standard or Premium
Prices start from £150, including VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. We confirm the exact price before booking.
What we need to know
A few details help us recommend the right survey and price. When you get in touch, it helps to mention:
- The kind of building and roof involved
- Your timetable, such as an exchange date
- How the loft is reached, if there is one
