How the survey works
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. Where a building in Stevenage has a manager or access rules, those are sorted out before the day. For homes, clear the way to the loft hatch and tell us about any leaks you know of. The written report follows, with photos.
- You tell us about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Keep pets inside or away from the areas we’re looking at
- Unlock side gates and any roof access doors
How to book
Our price is from £400, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or email us with the details.

How a thermal roof survey works in Stevenage
Thermal imaging is a useful tool, but it has limits. Sun, shade, reflective surfaces and wind can all change what the camera shows. That is why we check findings with moisture readings and a close visual inspection. The report is clear about what the images show and what they do not. Where something cannot be confirmed, we say what would help next. We survey pitched roof slopes, loft conversions and flat roofs, and the problems we are asked to look at most are damp patches with no obvious cause and water that travels before it shows.
Conditions on the day matter: drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day with a dry roof and little wind. In Stevenage, as anywhere, the forecast plays a part in when the visit happens, and it can move if conditions change. Some parts of a visit, such as a look in the loft, do not depend on the weather.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, with the urgent items made clear.

Why act early in Stevenage
A damp patch that keeps coming back typically has a cause that hasn’t been found. Thermal imaging with moisture readings can help narrow it down, instead of trying repair after repair. A small defect on a roof in Stevenage seldom stays small: a slipped slate or cracked ridge lets in water, water rots battens, and more slates or tiles follow. Early action is normally the cheaper option.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.

Our packages start from £150, inc. VAT. The price for your roof depends on:
- Which survey package you book

The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 with VAT included. We can help you choose the package that fits what you’d like to know.
What to let us know when you get in touch
A little information up front helps. It helps to include:
- The type of building and roof, like pitched or flat
- The reason for the survey, such as buying, a leak or storm damage
- Dates you are working to, such as exchange
- Any marks or damp showing indoors
Not sure which survey you need? It is easiest to ring 07833 053749 or use the contact form and describe the roof and what’s worrying you. We will talk you through the options and what they cost.
Rented homes, blocks and businesses

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Check outlets after heavy rain
- Move stored items away from the loft hatch
- Talk to us about the weather when booking
- Tell us where and when you’ve seen damp or stains
The report explains the conditions on the day and how they affected the images. That way you know how much weight to give each finding.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.
What a thermal roof survey looks like in Stevenage
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Stevenage was built as one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Low pitches and flat-roofed additions are hard to see from ground level, so aerial and thermal views add detail.
If you look after a building such as Saint Vincent de Paul Catholic Primary School, thermal images can show where wet insulation sits under a big flat roof. Historic houses like Aston Bury, about 2.5 miles south-east, show how far back building around Stevenage goes. Older roofs nearby can be steep and hard to see from ground level, and a survey by drone or thermal camera does not touch the roof itself.

Common questions in Stevenage
What do I need to do before a survey in Stevenage?
Very little. Keep pets out of the way, leave side gates unlocked and have any old roof paperwork handy.
Is Stevenage in the area you cover?
Yes, Stevenage is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can a thermal camera see water?
Not directly. It shows surface temperature, and wet areas can show up because they hold heat differently. We confirm what it suggests with moisture readings.
Does the report include photographs?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
How do I arrange a thermal roof survey in Stevenage?
Simply phone 07833 053749 or drop us an email. We’ll ask a few questions, confirm the price and agree a date.
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.
Signs you need a thermal roof survey in Stevenage
Flat roofs that have leaked for a while can have wet insulation under the covering. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
These are some of the problems a survey can pick up:
- Patches of heat loss across the roof
- Water that travels before it shows
- Missing or slipped insulation
- Damp around chimneys and parapets
For an older house near a landmark such as St Hugh & St John, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
