Thermal imaging roof survey in Woodside, Hertfordshire
Thermal imaging to find moisture and heat loss patterns in a roof for Woodside and the rest of Hertfordshire. Surveys run on weekdays and at weekends.
- Water that travels before it shows
- Damp around roof outlets and upstands
- Damp patches with no obvious cause
Can I check my roof myself?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where it applies.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
About our thermal roof survey in Woodside
Thermal imaging is useful when a damp patch has no clear cause. Leaks often run along a roof before they appear on a ceiling, and temperature patterns can help us trace where it may have come from. The images are used alongside a visual inspection and moisture readings, so no conclusion rests on one method alone. If you’re worried about stains that keep coming back and ceilings that feel colder in places, we can find out what’s behind it, on flat roofs, commercial roofs and pitched roof slopes alike.
In smaller places like Woodside, many homes are bungalows and houses with roofs you can partly see from ground level. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. Both depend on the weather on the day, as calm, dry conditions suit both. Close-up images frequently show wear on ridges, verges and flashings that can’t be judged properly from the ground.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Your questions about thermal roof surveys in Woodside
Will you come out to Woodside?
Yes, we do. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you carry out roof surveys in Woodside?
Yes, Woodside is one of the places we work. The survey and report are the same in Woodside as anywhere else, and visits run on weekdays and weekends.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
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. All of them come by email.
How long is the visit?
Time on site depends on the roof, but most surveys take between one and two hours on an ordinary house, though large, tall or awkward roofs take more time. The written report follows by email.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How much does a thermal roof survey cost?
Our Premium Survey, from £400, includes thermal imaging. An in-person consultation and a follow-up 12 months later are included too. For bigger commercial roofs, we quote on size.
Signs you need a thermal roof survey in Woodside
On big commercial and residential flat roofs, thermal imaging helps owners plan. It can suggest which areas may be wet and which seem dry, so we know where to take moisture readings.
Things that often lead to a survey include:
- Water that travels before it shows
- Heat escaping through the roof
- Wet areas near outlets and upstands
- Cold areas below the roof
If you run a business near Charter Place, big, flat commercial roofs are where close-up aerial shots and thermal images help most.
Before you book any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included
- Is VAT included in the price?
- When you will get the report
What a thermal roof survey does not cover
Some things can’t be seen without opening up the roof, and that sets some limits:
- Confirming water without moisture readings
- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check
If in doubt, ring 07833 053749 or drop us an email and we’ll suggest the right survey before booking. What a survey covers and does not.
What this survey covers
- Flat roofs
- Commercial roofs
- Ceilings below the roof
- Loft conversions
- Pitched roof slopes
- Insulated roof spaces
What a survey costs
Not every roof costs the same to survey, and it comes down to:
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- The roof’s overall size
- The type of building, from a house to a block or an office
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both including VAT. You will know the price for your roof before booking.
What we need to know
Here’s what helps us most when you contact us:
- When you need the report by
- Pictures of the roof from a safe spot, if you have them
- Where any leaks, stains or damp patches show inside
- The type of building and roof, like pitched or flat
Getting a price is simple: just phone 07833 053749 or drop us an email and give us a few details about the property and we will explain which survey suits. We confirm the price before anything is booked.
Flying and imaging in Woodside
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. With High Elms Manor about 0.7 miles north-east, Woodside sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
For site and facilities teams at buildings such as Alban Wood Primary School and Nursery, big roofs are where aerial photos and thermal images show the most at once. If you own one of the older houses in the streets near Church of All Saints, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
Woodside is about 2 miles north of Watford, in Hertfordshire. Anywhere in Woodside, we can carry out thermal roof surveys at your property. Across Hertfordshire, we cover Woodside. For surveys nearby, see our London page.

Different roofs, different checks
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are often laid over insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Felt and asphalt flat roofs
Felt and asphalt roofs often show wet areas as patches that differ from the rest. Moisture readings are used to check them.
What we do, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. For a survey in Woodside, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- 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.
- The Premium report reaches you the same day, and we go through it with you in person.
Before the survey
- Agree roof access with the managing agent if it’s shared
- If it is not your property yet, arrange access through the agent
- Have any questions written down, so nothing gets missed
