How a thermal roof survey works in Clapgate
Thermal imaging is often 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 combine the camera with an inspection from the loft where there is safe access. We survey flat roofs, loft conversions and pitched roof slopes, and the problems we’re asked to look at most are cold areas below the roof and stains that keep coming back.
In a village or hamlet like Clapgate, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report records the roof as we found it on the day. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Flying and imaging in Clapgate
The wider area around Clapgate has a long history of building, with Much Hadham Palace about 3.4 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. 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. Steep or complicated roofs are often hard to see from the ground, which is where aerial photos and thermal images help.
For site and facilities teams at buildings like Albury Church of England Voluntary Aided Primary School, big roofs are where close-up aerial shots and thermal images show the most at once. The streets around a church such as Church of St Mary are often among the oldest in a place, and if you own one of the older houses nearby, thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Clapgate is about 4 miles north-west of Bishop's Stortford, in Hertfordshire.

Why act early in Clapgate
For buyers, a thermal survey adds detail that a visual inspection can’t give. Finding hidden moisture before exchange gives you facts to raise with the seller. In a small place like Clapgate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

How the survey changes by roof type
Parapets, valleys and junctions
Parapet and valley gutters can overflow inside a building. Thermal images, checked with moisture readings, can help trace it.
Loft insulation
Insulation often gets moved during work in the loft. Thermal images can show where it has been pushed aside.
Landlords, agents and block managers in Clapgate
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
The survey, step by step
We will ask a few questions first, like when any problem began and what work has been done before. The inspection then takes about 1–2 hours for a house, and more on a big or complicated roof. In a small place like Clapgate, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- 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
- Mention any parking restrictions on your street
- Make a note of anything you’d like us to look at
- Find any records of previous roof work

Clapgate questions
Does a conservation area affect roof work in Clapgate?
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.
Do you carry out roof surveys in Clapgate?
Yes, Clapgate is one of the places we work. Every survey there gets the same written report with photos.
Does the report include photographs?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
What conditions are best for thermal imaging?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How long will you be at the property?
Time on site depends on the roof, but most surveys take between one and two hours at most homes, though large, tall or awkward roofs take more time. The written report follows by email.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Tell us about it when booking and we will plan the survey around it.
