Thermal imaging roof survey in St Ippolyts, Hertfordshire

How a thermal roof survey works in St Ippolyts
What a thermal camera can show depends a lot on the weather. It’s useful to have a sunny day beforehand, a dry surface and calm air. Rain, a strong wind or heavy cloud can make the images less clear. We will discuss the weather with you when booking, and the report explains how the conditions on the day affected the results. We’re often asked to look into wet insulation beneath the membrane and wet areas near outlets and upstands, on loft conversions, pitched roof slopes and commercial roofs.
Older buildings in small places like St Ippolyts 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. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

What a survey costs
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- The use of thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- Extra roofs, like extensions, dormers or garages
- How big the roof is
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both including VAT. We confirm the exact price before you book.
What we need to know
To price your survey accurately, we’ll ask about:
- Any deadline, such as an exchange date
- What made you get in touch
- Pictures from the garden or a window, if you have them
- How the loft is reached, if there is one
To arrange a survey, phone 07833 053749 or email us with the address and what you’d like to know about the roof. You will know the price before anything is booked.
What we do, step by step
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Rural addresses near St Ippolyts can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- A full inspection and thermal imaging are carried out together.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Jot down any questions you want answered
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work

What we look for on each type of roof
Felt and asphalt flat roofs
On felt and asphalt flat roofs, wet insulation can show as a temperature difference across the surface. Moisture readings are used to check them.
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We take that into account and check findings with moisture readings.
Questions from St Ippolyts
Is St Ippolyts within the area you cover?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Do you cover St Ippolyts?
Yes, St Ippolyts is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or send us an email and let us know about the property.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Can you check my loft insulation with a thermal camera?
The camera can point to heat loss and gaps in insulation. The survey isn’t an energy rating or a heat loss calculation, but the images show where improvements may help.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Do you climb onto every roof?
Only if it is safe. We inspect what can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
Do you need a thermal roof survey in St Ippolyts?
Some owners book because the rooms under the roof feel cold. Missing or slipped insulation can stand out as temperature differences, especially when it is warm inside and cold outside.
Most people get in touch when they’ve noticed one of these:
- Damp that repairs haven’t cured
- Areas of a flat roof that may hold water
- Cold areas below the roof
- Damp where roofs meet walls and chimneys
If you run a hotel or guest house in or near St Ippolyts, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition.
What to check before booking

- How long they’ve been surveying roofs

- Are they insured for the work?

Flying and imaging in St Ippolyts
St Ippolyts has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, large roofs are where photos from the air and thermal images show the most at once. 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. Many roofs like these cannot be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
If your home is one of the older ones in the streets near Church of St Ippolyts (church of England), tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement. Knebworth House lies about 4.4 miles south-east, so building around St Ippolyts goes back a long way. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition.

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, which helps when we look at the roof.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
