Thermal roof surveys for homes and businesses in Bishopsgate
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 phone 07833 053749 or email us with the address and a note of what you’ve noticed. Larger commercial roofs are quoted for their size. We survey loft conversions, insulated roof spaces and commercial roofs, and people most often book us about missing or slipped insulation and wet insulation beneath the membrane.
Somewhere as small as Bishopsgate, older roofs are frequently steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you cannot get from ground level. Weather and airspace are looked at before the visit. Steep slopes and tall chimney stacks are where a close-up view adds the most.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that is said too.

How it works
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. The survey typically takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere like Bishopsgate needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it’s safe.
- Thermal images are taken across the roof and, where there is safe access, in the loft.
- Patterns that stand out are checked with moisture readings.
- Each image is set beside a normal photo and explained in the report.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- If you are buying, check with the agent that we can get in
- Move anything stored under the loft hatch
Book a survey
If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.

How the survey changes by roof type
Loft insulation
Loft insulation is easily disturbed when people store things or run cables. The camera can show where it no longer covers the ceiling.
Pitched slate and tile roofs
Thermal images of a pitched roof can still show heat loss patterns and some damp areas. We explain what can and can’t be read from them.
Tips that help
From years of surveys, a few habits stand out as worth the effort:
- File the images with your roof records
- Check from the ground or a window, never by climbing
- Photograph damp patches with the date
- Note where damp appears and after what weather
You also get an in-person consultation with a Premium Survey, so you can go through the images with us. There’s a 12-month follow-up too.
Make sure loft insulation covers the whole area and hasn’t been disturbed. Gaps often appear after work in the loft.
Bishopsgate questions
Do you cover smaller places like Bishopsgate?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is my home in Bishopsgate 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.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and the South East.
Does thermal imaging detect leaks directly?
The camera does not see water itself. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
How long will you be at the property?
That depends on the size and shape of the roof; most visits take between one and two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. The report is sent afterwards by email.
Does the report include photos?
Yes. The report includes photos of what we found, so you can see exactly what each finding refers to.
What’s the best way to book?
The quickest way is to phone 07833 053749 or email us. Let us know the address and a little about the roof, and we will suggest the right survey. We survey on weekdays, Saturdays and Sundays.
What a thermal roof survey looks like in Bishopsgate
About 2.5 miles north lies Frogmore House, a reminder of how long the area around Bishopsgate has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail.
If you live in an older home near Royal Chapel of All Saints, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

Do you need a thermal roof survey in Bishopsgate?
Buyers sometimes want more than a visual look at the roof. A Premium Survey adds thermal imaging, a drone inspection where it applies and a same-day report, which helps when timescales are tight.
Typical things we’re asked to look at include:
- Wet areas near outlets and upstands
- Wet insulation beneath the membrane
- Thin or uneven insulation in the roof
- Damp where roofs meet walls and chimneys
If you look after a building like St John's Beaumont School, thermal images can show where wet insulation sits under a big flat roof.
What to check before booking
- When you’ll get the report
- Will they check the loft as well as the outside?
- What follow-up you get after the report
- Whether you get a written report with photos
