About our thermal roof survey in Northfields
Thermal imaging is part of our Premium Survey, which starts from £400. You also get a drone inspection where applicable, structural analysis and a report on the same day. An in-person consultation and a 12-month follow-up are included too. To book, just ring 07833 053749 or use the contact form with the address and what you’ve noticed. Larger commercial roofs are quoted for their size. If you’ve noticed damp around chimneys and parapets and gaps in loft insulation, a survey will tell you what’s going on, on insulated roof spaces, commercial roofs and loft conversions alike.
In London’s terraces and conversions, roofs are packed close together, 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. Tell us about the building and access when booking. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In Northfields, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent
- Make sure pets are kept safely away
- Make sure we can get to the back of the property

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Keep the report to compare against after any repair
- Clear a path to the loft hatch before we arrive
- Leave the roof to people with safe access
- Keep outlets and gutters clear to stop water sitting
Premium Surveys include an in-person consultation, giving you the chance to talk through the images and findings. A follow-up 12 months later is included as well.
Keep outlets and gutters clear so water drains off the roof quickly. Less standing water means less chance of it getting under the covering.
Rented homes, blocks and businesses
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Signs you need a thermal roof survey in Northfields
Once a leak has been fixed, people often 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.
Look out for signs like these:
- Gaps in loft insulation
- Areas of a flat roof that may hold water
- Ceilings that feel colder in places
- Heat escaping through the roof
Boston Manor lies about 0.5 miles south, so building around Northfields goes back a long way. For older roofs nearby, a look from above or with a thermal imager is a hands-off way to check condition.
What to check before booking
- What the report includes, and whether it has photographs
- Are they insured for the work?
- Whether the loft space is looked at, where there is one
- Is VAT included in the price?

Northfields: your questions answered
Is my home in Northfields listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is parking a problem for a survey in Northfields?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What does a thermal roof survey show?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Airspace, weather and Northfields roofs
If the drone is used for your survey, we check the Drone Safety Map for restrictions before flying. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Northfields is one of them, bay roofs, hips and later dormers each have their own details. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
If you run a business near Treaty Centre, big, flat commercial roofs are where photos from the air and thermal images help most. For hotels and guest houses around Northfields, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

Why it is worth a survey now in Northfields
Thermal images can suggest the extent of wet areas without cutting into the roof. That helps you and your roofer decide what really needs replacing. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.
