About our thermal roof survey in Forest Hill
A thermal camera can help when the cause of damp isn’t obvious. Water can travel some distance under a roof covering before it shows inside, and temperature patterns can help us trace where it may have come from. We combine the images with a visual inspection and moisture readings, so the findings don’t rely on the camera alone. We survey loft conversions, pitched roof slopes and flat roofs, and people most frequently book us about wet areas near outlets and upstands and water getting in at parapets and stacks.
London roofs sit shoulder to shoulder in terraces and blocks, so privacy and neighbours matter as much as the view. Images are taken to show the roof we’re surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building when booking. The extra view helps most on steep slopes, tall stacks and rear additions.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Questions from Forest Hill
Can you fly a drone over a roof in Forest Hill?
That depends on where the roof is and on the weather. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather, though the rest of the survey goes ahead either way.
Can parking be tricky for a visit in Forest Hill?
It depends on the street. If Forest Hill has controlled parking where you are, a visitor permit is the easiest answer.
Will you go up on the roof?
Only where it is safe to do so. We inspect whatever is safely visible: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
How does a thermal imaging roof survey work?
A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. Findings are checked with moisture readings.
How experienced are you?
More than 5,000 surveys over 20+ years.
Do you carry out surveys on Saturdays and Sundays?
Surveys run on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or use the contact form.
What we look for on each type of roof
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Parapets, valleys and junctions
Junctions where roofs meet walls, parapets and valleys are common places for water to get in. Thermal imaging can help show damp patterns around them.
What a survey costs
To price your survey, we look at:
- Any need for thermal images or a drone flight
- The size of the roof
- The type of building, from a house to a block or an office
- Whether you choose the Basic, Standard or Premium Survey
All our prices include VAT. Thermal roof survey starts from £400, including VAT. We confirm the price for your roof before booking.
Helping us price your survey
To price your survey accurately, we will ask about:
- Access details, such as a loft hatch or a shared roof
- The style of property, from a terrace to a block
- Pictures of the roof from a safe spot, if you have them
- The reason for the survey, like buying, a leak or storm damage
When you’re ready to go ahead, call 07833 053749 or use the contact form. We will suggest a package, agree the price and find a date.
Checking the roof from the ground
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
Thermal roof surveys around Forest Hill
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
Parking in Forest Hill, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway as you book. If you run a business near Lewisham Shopping Centre, big, flat commercial roofs are where photos from the air and thermal images help most. The streets around a church such as Honor Oak Christian Fellowship Centre are often among the oldest in a place, and if your house is among the older ones nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view from the air or with a thermal camera helps.

The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two for most houses; commercial roofs usually need 3–4 hours. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We check the roof from the ground, from windows and from the roof itself where it is safe.
- Thermal images are taken to show differences in surface temperature.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Have any paperwork from past roof work to hand
- Agree roof access with the managing agent if it is shared
- Buyers: confirm access with the estate agent or seller
How to book
Photos help, if you have them. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or email us.

Why it is worth a survey now in Forest Hill
If a big flat roof may need replacing, knowing the wet areas first is useful. Images backed by moisture readings show where problems seem to be before you spend. Blocked gutters and hoppers on London houses overflow and soak brickwork. A blocked outlet ignored for a winter or two can mean damp walls inside.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you need to know.
