Thermal imaging roof survey in Frogmore, Hertfordshire
Thermal roof surveys in Frogmore from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and South East England.
- Areas of a flat roof that may hold water
- Water that travels before it shows
- Cold areas below the roof
DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book and it will help the survey.
How a thermal roof survey works in Frogmore
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. Patterns can suggest where water is trapped under the covering. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there is safe access. Common reasons to book are patches of heat loss across the roof and thin or uneven insulation in the roof, on commercial roofs, insulated roof spaces and pitched roof slopes.
In a small place like Frogmore, open ground can mean strong wind. A small drone cannot fly safely in strong wind or a downpour, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Frogmore: your questions answered
Is Frogmore within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Is Frogmore in the area you cover?
Yes. Our area covers London and the South East, and Frogmore is part of that. Just call 07833 053749 or email us and tell us about the property, and we’ll talk through which survey suits.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access; we’ll agree the details when you book.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, and moisture readings are used to check it.
How we price thermal roof surveys
Several things affect the price of a survey:
- House, block, shop or office
- Whether thermal imaging or a drone is needed
- Extra roofs, like extensions, dormers or garages
- Basic, Standard or Premium
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Helping us price your survey
What helps most when you contact us:
- Anything about access we should know
- Your postcode, so we can check access and travel
- Where any leaks, stains or damp patches show inside
- Pictures of the roof from a safe spot, if you have them
Getting a price is simple: just ring 07833 053749 or drop us an email and give us some details about the property and we will explain which survey suits. The price is agreed up front.
What we are asked to look at in Frogmore
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when it is warm inside and cold outside.
Signs worth acting on include:
- Damp around chimneys and parapets
- Leaks far from where the stain appears
- Damp that repairs haven’t cured
- Patches of heat loss across the roof
High Elms Manor lies about 2.8 miles south-west, so building around Frogmore goes back a long way. Close-up aerial shots and thermal images let an old roof be checked without anyone disturbing it.
What to check before booking
- How soon the report will arrive
- What the report includes, and whether it has photos
- Is VAT included in the price?
- Whether the loft is part of the inspection
Landlords, agents and block managers in Frogmore
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, take photographs as we go and record our findings for the written report. It usually takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. For a village or hamlet like Frogmore, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect what can safely be seen, inside and out.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- We look at the roof from the ground, from windows and from the roof itself where it’s safe.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
Before we arrive
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- Leave a clear route to the loft
Book a survey
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.
Advice
What a thermal roof survey looks like in Frogmore
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
For businesses in and around places such as The Maltings, large commercial roofs are often easiest to see from the air or with a thermal camera. If you live in an older home near Church of the Holy Trinity, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from above or with a thermal imager helps.
Frogmore is about 2 miles south of St Albans, in Hertfordshire. Houses, flats, blocks and commercial buildings in Frogmore can all book thermal roof surveys. Our area takes in places right across Hertfordshire, from the larger towns to small villages. For surveys nearby, see our London page.

Why act early in Frogmore
For buyers, a thermal survey adds detail that a visual inspection can’t give. Hidden problems found before exchange can be raised with the seller or agent. In a place like Frogmore, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
