Thermal roof surveys for homes and businesses in Tyttenhanger
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. Typical surveys look at damp where roofs meet walls and chimneys and ceilings that feel colder in places, on insulated roof spaces, commercial roofs and loft conversions.
In a village or hamlet like Tyttenhanger, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what can’t be reached safely. Both the forecast and the airspace are checked first, and the journey is planned ahead of time. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Your questions about thermal roof surveys in Tyttenhanger
Is my home in Tyttenhanger listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will you come out to Tyttenhanger?
Yes, Tyttenhanger is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Will you photograph what you find?
Yes. Photographs are part of every report.
What’s the best way to book?
Simply ring 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.

How we price thermal roof surveys
A few things affect what a survey costs:
- Roof area
- Extra roofs, like extensions, dormers or garages
- Basic, Standard or Premium
- Height and safe access
Prices start from £400, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.
Booking your survey
These details help when you get in touch:
- Whether there’s a loft hatch, a shared roof or tricky access
- Any stains, drips or damp patches you’ve seen indoors
- Pictures of the roof from a safe spot, if you have them
- Your postcode, so we can check access and travel
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To get started, ring 07833 053749 or drop us an email.

What else we do in Tyttenhanger
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. It typically takes an hour or two at a typical home, and longer for a large or complex roof. Somewhere as small as Tyttenhanger, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- We take thermal images of the roof to pick up temperature patterns.
- Any patterns of interest are checked with moisture readings where we can reach them.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- Keep pets inside or away from the areas we’re looking at
- Make a note of anything you’d like us to look at
- If you are buying, let the agent know when we’re coming
Arrange a survey
A quick phone call is usually the easiest start: call 07833 053749 or send us an email, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
Advice
Airspace, weather and Tyttenhanger roofs
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. Historic houses such as Batchwood Hall, about 3.3 miles north-west, show how far back building in the area around Tyttenhanger goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
Take a building like Nicholas Breakspear School: a view from above covers a wide roof far faster than walking it. The streets around a church such as Church of St Mark are often among the oldest in a place, and if your house is among the older ones nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Tyttenhanger is about 2 miles south-east of St Albans, in Hertfordshire. Tyttenhanger is one of many places we visit across Hertfordshire, for homes and businesses alike. Tyttenhanger is one of the places in Hertfordshire we cover for thermal roof surveys. We also survey roofs in London.
Every address in AL4 is within our area for thermal roof surveys, from the main roads to the quietest streets.

The nearest railway station is St Albans station, about 1.7 miles north-west. A little further out are Hill End Hospital (0.9 miles north-west) and St Albans Musical Museum (1.9 miles north-west).

What we are asked to look at in Tyttenhanger
Some defects simply can’t be seen with the eye. Wet insulation, gaps in insulation and heat loss are often invisible from outside. Thermal imaging gives us another way to look for them.
Signs worth acting on include:
- Damp around chimneys and parapets
- Water that travels before it shows
- Heat escaping through the roof
- Cold spots on ceilings under the roof
Shop and office owners around The Maltings may find that big, flat commercial roofs are where aerial photos and thermal images help most.
Choosing a roof surveyor
- Their report turnaround times
- What insurance they carry
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Is there a chance to talk the report through?
Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Don’t climb onto the roof to look for leaks yourself
- Keep outlets and gutters clear to stop water sitting
- Note where damp appears and after what weather
- Take photos of stains as they appear, so we can compare
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There is a 12-month follow-up too.
Keep an eye on ceilings under the roof for new stains. Catching a leak early stops insulation getting soaked.
Different roofs, different checks
Single-ply and EPDM roofs
On big single-ply roofs, the camera helps show where to take readings. It focuses the survey on the areas that matter.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
