Thermal roof survey in Sewardstone: what you get
Thermal imaging can also show where a roof is losing heat. Missing or slipped insulation and gaps at the eaves often show up as temperature differences. The difference shows most clearly when it is warm inside and cold outside. The report shows the images and explains what they may mean. It isn’t an energy rating or a heat loss calculation. We survey insulated roof spaces, ceilings below the roof and flat roofs, and people most often book us about damp around roof outlets and upstands and cold spots on ceilings under the roof.
London airspace is busy and tightly controlled: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every address in Sewardstone is checked before any drone flight, and permission is never taken for granted.
The report records the roof as we found it on the day. That makes it useful now and a handy reference later.

When you need someone else
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Whether the deck or roof structure is strong enough
- The condition of timbers we cannot see
- Reliable images in rain, strong wind or on a wet roof surface
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer before you book. What a survey covers and does not.
Roofs we survey in Sewardstone
- Insulated roof spaces
- Commercial roofs
- Pitched roof slopes
- Loft conversions

- Ceilings below the roof
Rented homes, blocks and businesses
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or use the contact form with the addresses.
How the survey works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. 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 as you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- We take thermal images of the roof to pick up temperature patterns.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
Before the survey
- Dig out any old roof reports or invoices
- Clear the way to the loft hatch
- Point out any leaks or damp patches
Getting a price
Unsure which package suits your roof? It’s easiest to call 07833 053749 or send us an email and describe the roof and why you want it surveyed. We’ll talk you through the options and what they cost.
Advice
Airspace, weather and Sewardstone roofs
The wider area around Sewardstone has a long history of building, with Forty Hall about 2.8 miles west. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Steep or complicated roofs are often hard to see from ground level, which is where photos from the air and thermal images help.
If you run a business near Edmonton Green Shopping Centre, large commercial roofs are often easiest to see by drone or thermal camera. For site and facilities teams at buildings such as Prince of Wales Primary School, big roofs are where close-up aerial shots and thermal images show the most at once. Parking in Sewardstone, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier.
Sewardstone is about 2 miles south of Waltham Abbey, in Greater London. Anywhere in Sewardstone, we can carry out thermal roof surveys at your property. Across Greater London, we cover Sewardstone and the places around it. You can also see our page for London.

FAQs for Sewardstone
Is my home in Sewardstone listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Can parking be tricky for a visit in Sewardstone?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. That way the visit can be planned around it.
Is thermal imaging good for finding leaks?
It’s a useful tool for tracing leaks, but not the only one. What it shows depends on the weather and the roof. Where it can’t be pinned down, the report suggests a next step, like electronic leak detection.
Do you cover Sewardstone?
Yes. Sewardstone is part of the area we cover, and the service is the same as everywhere else we work.
Can a thermal camera see water?
No, not on its own. It shows temperature, and wet materials often behave differently from dry ones. We confirm what it suggests with moisture readings.
Can thermal imaging show missing insulation?
Thermal images can suggest where heat is escaping and where insulation may be missing. The survey isn’t an energy rating or a heat loss calculation, but the images show where improvements may help.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, backed by photos. Anything we couldn’t see safely is noted too.
What we look for on each type of roof
Pitched slate and tile roofs
From inside the loft, the camera can help with damp around chimneys, valleys and roof windows. Findings are checked with moisture readings.
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.
Tips from our surveys
Small things make a difference. Some pointers:
- Photograph damp patches with the date
- Use the report as a baseline for later checks
- Don’t switch the heating off before the visit
- Remember the conditions on the day affect the results
After the visit, we put the thermal images, photographs and moisture readings into one report. Each image is explained in plain words, with our recommendations. With a Premium Survey, you get the report the same day.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
Checking the roof from ground level
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
