Thermal roof survey in Holwellbury
We present each thermal image next to a normal photo of the same area, so it is easy to see which part of the roof each one shows. We explain what each pattern may mean, what the moisture readings found and what we recommend. Premium reports are sent the same day. You can talk the findings through with us at the in-person consultation. There’s a 12-month follow-up as well. Typical surveys look at heat escaping through the roof and areas of a flat roof that may hold water, on commercial roofs, ceilings below the roof and loft conversions.
In a small place like Holwellbury, open ground can mean strong wind. Strong wind or a downpour stops a small drone flying, and calm conditions also suit thermal imaging best. The visit is planned around the forecast, along with the journey and access. If the day turns windy or wet, the visit can be moved.
The report records the roof as we found it on the day. It is useful right away, and a good reference for later, like when you want to compare after future work.

What a thermal roof survey looks like in Holwellbury
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up photos from the air and thermal images help. An older home may be listed, or stand 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.
Anyone responsible for a site like Derwent Lower School will know that big roofs are where close-up aerial shots and thermal images show the most at once.
Holwellbury is about 3 miles north-west of Letchworth, in Hertfordshire. Houses, flats, blocks and commercial buildings in Holwellbury can all book thermal roof surveys. Our area takes in places right across Hertfordshire. There is also a page for Milton Keynes.

Your questions about thermal roof surveys in Holwellbury
Is Holwellbury within the area you cover?
Yes. Holwellbury is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Is my home in Holwellbury listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
How long will you be at the property?
Time on site depends on the roof, but most surveys take an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. The written report follows by email.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
Common roof problems in Holwellbury
Not every roof problem shows on the surface. Wet insulation, gaps in insulation and heat loss are frequently invisible from outside. Thermal imaging gives us another way to look for them.
We’re frequently asked to look at:
- Water that travels before it shows
- Wet areas near outlets and upstands
- Gaps in loft insulation
- Water getting in at parapets and stacks
Take an older house close to Church of St Peter (C of E) at Corner with Holwell Road: older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help.
Before you book anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Is VAT included in the price?
- Their insurance cover
- How much experience they have with roofs like yours
Can I check my roof myself?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
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. Notes and photos go into the written report. It usually takes an hour or two at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a small place like Holwellbury, access is usually 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.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Keep pets in another room
- Have any paperwork from past roof work to hand
- Let us know about any leaks, stains or damp patches you know of

Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. For older village homes like those around Holwellbury, the right replacement materials aren’t always easy to find quickly. That is one more reason to find defects before they become urgent.
