About our thermal roof survey in Furnace Wood
On a flat roof, wet insulation holds heat longer than dry insulation. 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 typically tell from the surface. We then check those areas with moisture readings. We survey insulated roof spaces, pitched roof slopes and commercial roofs, and common reasons people get in touch are water getting in at parapets and stacks and water that travels before it shows.
In a village or hamlet like Furnace Wood, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what can’t be reached safely. Weather and airspace are looked at before the visit, and the journey is planned beforehand. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the roof, any defects and our written recommendations.

Why it is worth a survey now in Furnace Wood
Wet insulation under a flat roof does not dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding them early can mean a smaller job. Older cottages and farmhouses around Furnace Wood can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.

What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere as small as Furnace Wood, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- The roof is inspected visually from safe viewpoints.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Before the survey
- Note where any stains or damp appear
- Have any questions written down, so nothing gets missed
- If the roof is shared, arrange access with whoever manages the building

What else we do in Furnace Wood
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

Furnace Wood questions
Is drone flying allowed in Furnace Wood?
It depends on the exact address and the weather on the day. The flight restriction zone around Gatwick Airport comes within about 2 miles of Furnace Wood. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. A small drone cannot fly safely in strong wind or a downpour.
Is Furnace Wood within the area you cover?
Yes, Furnace Wood is covered. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and they go into the written report alongside our recommendations.
Can you survey at the weekend?
Surveys run on any day of the week. To find a day that suits you, call 07833 053749 or drop us an email.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years, and 98% of customers are satisfied.
Are you structural engineers?
No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Common roof problems in Furnace Wood
After a long-running leak, insulation under a flat roof can stay wet. Owners want to know how far it has spread before deciding what to do. Thermal images and moisture readings together can show the likely extent.
Look out for signs like these:
- Thin or uneven insulation in the roof
- Damp around roof outlets and upstands
- Ceilings that feel colder in places
- Damp around chimneys and parapets
Anyone responsible for a site like Felbridge Primary School will know that thermal images can show where wet insulation sits under a big flat roof.
