How a thermal roof survey works in Amwell

Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where it applies, structural analysis and a report on the same day. An in-person consultation and a 12-month follow-up are included too. You can call 07833 053749 or use the contact form with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey insulated roof spaces, loft conversions and commercial roofs, and common reasons people get in touch are water that travels before it shows and damp around chimneys and parapets.

In a small place like Amwell, open ground can mean strong wind. High wind or heavy rain stops a small drone flying, and calm conditions also suit thermal imaging best. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.

You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What a thermal roof survey doesn’t cover

Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:

  • The condition of timbers we can’t see
  • Seeing water directly, as the camera shows temperature, not moisture
  • Reliable images in rain, strong wind or on a wet roof surface

If you are not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. What a survey covers and doesn’t.

What this survey covers

  • Flat roofs
  • Insulated roof spaces
  • Ceilings below the roof
  • Loft conversions
  • Pitched roof slopes
  • Commercial roofs

What we look for on each type of roof

Pitched slate and tile roofs

Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and can’t be read from them.

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.

Thermal roof surveys in Amwell: local notes

In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. If your survey includes the drone, the flight is checked against the Drone Safety Map first.

Historic houses such as Childwickbury Manor, about 2.6 miles south-west, show how far back building around Amwell goes. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition. The streets around a church like St Helen's Church 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. Anyone responsible for a site like St Helen's Church of England Primary School will know that thermal images can show where wet insulation sits under a big flat roof.

Amwell is about 2 miles south-east of Harpenden, in Hertfordshire. From houses to flats and shops in Amwell, the roof can be surveyed on a weekday or at the weekend. Our Hertfordshire coverage includes Amwell. There is also a page for London.

Your questions about thermal roof surveys in Amwell

Do you cover Amwell?

Yes, Amwell is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.

Does a conservation area affect roof work in Amwell?

Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.

Can you do a thermal survey in any weather?

Conditions on the day have a big effect on what the camera can show. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.

Does someone need to be in?

Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.

Will thermal imaging find my leak?

It’s a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. Where it cannot be pinned down, the report suggests a next step, like electronic leak detection.

How experienced are you?

Over 20 years and more than 5,000 surveys.

When does the report arrive?

Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when you book.

Before and after the survey

You do not need to be a roofer to help. Here’s what helps most:

  • Do not switch the heating off ahead of the visit
  • Tell us where and when you’ve seen damp or stains
  • Ask us about the forecast if rain is expected
  • Keep the report to compare against after any repair

The report explains the conditions on the day and how they affected the images. It helps you judge how firm each finding is.

Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.

Leave it or get it looked at?

Once insulation under a membrane is wet, it tends to stay wet. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. In a place like Amwell, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.

Our price is from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.

How the survey works

A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and make notes for the report. Most visits take an hour or two at most homes, and more on a big or complicated roof. Somewhere like Amwell needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.

  1. We talk through the roof, any damp or leaks, and the weather expected on the day.
  2. We check the roof from ground level, from windows and from the roof itself where it is safe.
  3. A thermal camera records how the surface temperature varies across the roof.
  4. Areas that look unusual on the camera are checked with moisture readings where possible.
  5. We write up the thermal images alongside ordinary photos and recommendations.

Before we arrive

  • For a flat or shared roof, check access with the freeholder or managing agent
  • Keep pets inside or away from the areas we’re looking at
  • Make sure the loft hatch can be reached

Getting a price

Booking is simple: just ring 07833 053749 or send us an email, let us know about the property and we’ll point you to the right survey. The price is agreed up front.
