Thermal roof surveys for homes and businesses in St Luke's
Our Premium Survey, from £400, brings together a full roof inspection and thermal imaging. You also get a drone inspection where it applies, structural analysis and a report on the same day. There’s an in-person consultation as well, plus a follow-up 12 months later. To book, just phone 07833 053749 or drop us an email with the address and what you’ve noticed. For big commercial roofs, we quote on size and access. If you are worried about leaks that are hard to trace and cold spots on ceilings under the roof, we can find out what’s behind it, whatever the roof.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Every address in St Luke's is checked before any drone flight, and where permission is needed, the flight waits for it.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. We survey on weekdays, Saturdays and Sundays, which can make access easier.
Letting agents and landlords in St Luke's book surveys as well as homeowners. A written report with photos gives you a clear record of the roof, useful for planning maintenance.
Your questions about thermal roof surveys in St Luke's
Does a conservation area affect roof work in St Luke's?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is parking a problem for a survey in St Luke's?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
Is it the same as a RICS Level 2 or Level 3 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 do I arrange a thermal roof survey in St Luke's?
To arrange a survey, phone 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Does thermal imaging detect leaks directly?
No, not on its own. It shows temperature, and wet materials frequently behave differently from dry ones. That’s why we check any patterns with moisture readings.
Different roofs, different checks
Single-ply and EPDM roofs
Single-ply PVC, TPO and EPDM roofs are frequently laid over insulation boards. Wet boards can show as temperature differences on the images.
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. The camera can help show where to look.
How it works
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely. The survey typically takes about one to two hours for most houses, though large, tall or awkward roofs take more time. In St Luke's, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Clear the way to the loft hatch
- Unlock side gates and any roof access doors
- Dig out any old roof reports or invoices

What a survey costs
All our prices include VAT. What changes the price is:
- Extra roofs, like extensions, dormers or garages
- Roof area
- Whether it’s a home or a commercial building
- Which survey package you book
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
What we need to know
What helps most when you contact us:
- Anything about access we should know
- The address and postcode of the property
- Your timetable, such as an exchange date
- The kind of building and roof involved
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or send us an email.
Do you need a thermal roof survey in St Luke's?
Once a leak has been fixed, people frequently ask whether the roof is still wet. A thermal survey with moisture readings can show whether wet areas remain when the conditions on the day are suitable.
Most people get in touch when they’ve noticed one of these:
- Patches of heat loss across the roof
- Stains that keep coming back
- Possible trapped moisture under a flat roof covering
- Damp where roofs meet walls and chimneys
For hotels and guest houses around St Luke's, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.
What to check before booking
- What experience they bring
- Whether you can ask questions once you have the report
- Whether they hold professional indemnity and public liability insurance
- How they’ll see the roof: from the ground, the loft, the roof or by drone
Flying and imaging in St Luke's
St Luke's is about 1 mile from the restricted area over the City of London, where drone flights need permission from NATS. If your survey includes the drone, the address is checked against it before any flight. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in St Luke's is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
With Mansion House about 0.8 miles south, the area around St Luke's has a long history. Aerial photos and thermal images let an old roof be checked without anyone disturbing it. Anyone responsible for a site like St Luke's CofE Primary School will know that a view from above covers a wide roof far faster than walking it.

Before and after the survey
Here are a few things we’d tell any owner:
- Remember the conditions on the day affect the results
- Take photos of stains as they appear, so we can compare
- Do not switch the heating off ahead of the visit
- Check outlets after heavy rain
Many people send the report to roofers, who can then quote for the areas shown. Because the images are paired with photos, it is easy to find each area on the roof.
Check loft insulation covers the whole area and hasn’t been disturbed. Insulation is often moved when people work in the loft space.
