Thermal imaging roof survey in Garston, Hertfordshire
Thermal imaging to find moisture and heat loss patterns in a roof in Garston. We have completed more than 5,000 surveys across London and South East England.
- Thin or uneven insulation in the roof
- Damp where roofs meet walls and chimneys
- Damp around roof outlets and upstands
Common roof problems in Garston
Unexplained damp is one of the main reasons people ask for thermal imaging. A leak may start well away from where the stain appears. Temperature patterns can help narrow down where to look.
Typical things we are asked to look at include:
- Water getting in at parapets and stacks
- Damp around roof outlets and upstands
- Stains that keep coming back
- Cold spots on ceilings under the roof
For an older house near a landmark such as Stanborough Park Church, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Choosing a roof surveyor
- How long the report takes to arrive
- How long they’ve been surveying roofs
- Whether you can ask questions once you have the report
- Which viewpoints they use to see the roof
How a thermal roof survey works in Garston
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. Common reasons to book are wet insulation beneath the membrane and cold areas below the roof, across ceilings below the roof, pitched roof slopes and insulated roof spaces.
Around Garston, older homes can have thin loft insulation and later additions with roofs of their own. Thermal patterns and close-up photos together give a fuller picture of the roof. Findings are checked with moisture readings where needed. Results depend on the weather, so the visit is planned around the forecast.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Roof by roof
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
What we do, step by step
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes between one and two hours for most houses, while a commercial roof takes nearer three to four hours. Homes around Garston frequently have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- Check pets are kept safely away
- Leave side gates unlocked
- Mention any parking restrictions on your street

Advice
What a survey costs
The price reflects the time and kit the roof needs. That comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- House, block, shop or office
- The number of roofs, including extensions and garages
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.
Booking your survey
To price your survey accurately, we’ll ask about:
- What made you get in touch
- The property’s address and postcode
- What kind of property and roof it is
- Photos of the roof, taken safely from the ground or a window

Your questions about thermal roof surveys in Garston
Is my home in Garston listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Garston within the area you cover?
Yes, Garston is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How long is the visit?
Time on site depends on the roof; most visits take about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. The written report follows by email.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, let us know when booking.
How much does a thermal roof survey cost?
It’s part of the Premium Survey, from £400. You also get an in-person consultation and a 12-month follow-up. For bigger commercial roofs, we quote on size.
How does a thermal imaging roof survey work?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, and we check them with moisture readings.
Why it is worth a survey now in Garston
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Looking now, while the damage may still be limited, keeps more options open. Around Garston, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
