Thermal imaging roof survey in Turnpike Lane, Greater London
We take a careful look at the roof at your property in Turnpike Lane, and put it all in a photo-illustrated written report.
- Thin or uneven insulation in the roof
- Leaks that are hard to trace
- Damp around roof outlets and upstands
About our thermal roof survey in Turnpike Lane
Thermal imaging is useful when a damp patch has no clear cause. Leaks frequently run along a roof before they appear on a ceiling, and the camera can show patterns that help us follow it. We combine the images with a visual inspection and moisture readings, so no conclusion rests on one method alone. If you are worried about gaps in loft insulation and leaks that are hard to trace, a survey will tell you what’s going on.
London roofs sit shoulder to shoulder in terraces and blocks, which makes care around neighbours part of the job. We take care to focus on the roof we’ve been asked to look at. Let us know about the building and access when booking. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Do you need a thermal roof survey in Turnpike Lane?
Building owners and managing agents use thermal surveys to plan work on larger flat roofs. Patterns can point to wet areas and show which parts look sound, so moisture readings can be targeted.
People typically book a survey when they’ve noticed one of these:
- Water that travels before it shows
- Heat escaping through the roof
- Wet areas near outlets and upstands
- Damp where roofs meet walls and chimneys
Turnpike Lane is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.
Questions to ask before booking
- Will the report include photos?
- Their track record with similar roofs
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- When you’ll get the report
What a thermal roof survey looks like in Turnpike Lane
About 1.5 miles north-east lies Bruce Castle, a reminder of how long the area around Turnpike Lane has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
If you look after a shop, office or commercial unit, for instance near The Mall Wood Green, thermal images can show trapped moisture across a wide commercial roof. Take an older house close to Church of St John The Baptist (greek Orthodox): steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that’s where a view from above or with a thermal imager helps.
Turnpike Lane is about 3 miles north of Highbury, in Greater London. From houses to flats and shops in Turnpike Lane, we can survey the roof. Across Greater London, we cover Turnpike Lane. We also survey roofs in London.
All of N8, N22 and N15 is within our area for thermal roof surveys. That includes homes and businesses on Bury Road, High Road and Glebe Road and the roads around them. If you are just outside Turnpike Lane, we cover Hornsey (1 mile west), Noel Park (1 mile north), Wood Green (1 mile north), Stroud Green (1 mile south) and Crouch End (1 mile south-west). Within a short drive, we also cover London (6 miles south), City of Westminster (6 miles south), Marylebone (5 miles south), Kensington (7 miles south-west), St Pancras (4 miles south) and Shoreditch (5 miles south).
Around Turnpike Lane
Typical jobs here are in homes near Moselle Upper School, The Toll Gate pub and Ducketts Common, among other places. There is a railway station in Turnpike Lane itself: Hornsey station. Other landmarks nearby include Hornsey Central Hospital (1.1 miles west) and The Mall Wood Green (less than half a mile north). The countryside around Turnpike Lane includes Darland's Lake and Railway Fields.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we look at the roof.
What affects the price in Turnpike Lane
Survey packages start from £150, with VAT included. The price for your roof depends on:
- Roof area
- The height of the building and how the roof can be seen safely
- The type of building, from a house to a block or an office
- Extra roofs, like extensions, dormers or garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.
What to tell us when you contact us
Here’s what helps us most when you get in touch:
- How the loft is reached, if there is one
- Any marks or damp showing indoors
- What’s prompted the survey
- The kind of building and roof involved
Photos help, if you have them. Take them safely from ground level or a window, and please don’t climb up for a closer look. To send them or to book, call 07833 053749 or use the contact form.
What happens on the day
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. London terraces rarely offer a view of the whole roof from one spot, so in Turnpike Lane we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We look at the roof from ground level, from windows and from the roof itself where it’s safe.
- A thermal camera records how the surface temperature varies across the roof.
- Areas that look unusual on the camera are checked with moisture readings where possible.
- You get a report with thermal images, photographs and our recommendations.
Before we arrive
- Note where any stains or damp appear
- If the roof is shared, arrange access with whoever manages the building
- Tell us about parking before the day

Turnpike Lane questions
Is my home in Turnpike Lane listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Can parking be tricky for a visit in Turnpike Lane?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and they go into the written report.
How long is the visit?
It normally takes roughly 1–2 hours on an ordinary house, and about three to four hours for a commercial roof. We will confirm the timing when you book.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Clear a path to the loft hatch before we arrive
- Leave the roof to people with safe access
- Take photos of stains as they appear, so we can compare
- Use the report as a baseline for later checks
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. Water that gets under a covering can spread a long way before it shows.

Roof by roof
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We take that into account and check findings with moisture readings.
Pitched slate and tile roofs
Slate and tile roofs are frequently harder to read with a thermal camera, because of the air space beneath. We combine the images with an inspection from the loft where there’s safe access.
