Thermal roof surveys for homes and businesses in Waltham Cross
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. This can give an idea of how far water has travelled beneath the membrane, something you cannot usually tell from the surface. We then check those areas with moisture readings. Common reasons to book are missing or slipped insulation and cold spots on ceilings under the roof, on commercial roofs, flat roofs and loft conversions.
Around Waltham Cross, lots of roofs are low enough to see partly from the garden or the street. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. Both depend on the weather on the day. Close-up images frequently show wear on ridges, verges and flashings that can’t be judged properly from the ground.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the roof, any defects and our written recommendations.

Common questions in Waltham Cross
How do I find out if my home in Waltham Cross is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Do you cover smaller places like Waltham Cross?
Yes, Waltham Cross is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
What does the report include?
A written report with photographs, covering the condition of the roof, the defects we found and what we recommend, in order of urgency where relevant. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Will you photograph what you find?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
What can thermal imaging tell me about my roof?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.

Practical tips
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Note where damp appears and after what weather
- Keep outlets and gutters clear to stop water sitting
- Check the loft can be reached safely
- Keep dated photos of any marks on ceilings
You can pass the report to a roofer so they can see where the problem areas seem to be. Because the images are paired with photos, it’s easy to find each area on the roof.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
For landlords and managing agents
Letting agents can arrange access with tenants. We survey seven days a week, which helps when tenants work during the week.
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
What happens if roof problems are left?
Before replacing a large flat roof, it helps to know how much of it is actually wet. Thermal imaging, checked with moisture readings, gives a clearer picture before you spend. Around Waltham Cross, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.

How the survey works
The visit has one job: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. With a bit of garden around a house, as there often is around Waltham Cross, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- 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.
How to prepare
- Have any questions written down, so nothing gets missed
- If you are buying, check with the agent that we can get in
- Show us where any leaks or stains appear

Advice
Checking the roof from the ground
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
What a thermal roof survey looks like in Waltham Cross
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help. Historic houses like Forty Hall, about 2.1 miles south-west, show how far back building in the area around Waltham Cross goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Take an older house close to Christ Church: thin or patchy insulation under an old roof often shows up clearly on a thermal image. Anyone responsible for a site like Four Swannes Primary School will know that a drone or thermal camera can show a large roof in a single visit.
