Independent thermal roof surveys in Fernhill

When to book a survey in Fernhill

After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.

Things that frequently lead to a survey include:

  • Patches of heat loss across the roof
  • Thin or uneven insulation in the roof
  • Water getting in at parapets and stacks
  • Areas of a flat roof that may hold water

For site and facilities teams at buildings like Oakwood School, big roofs are where photos from the air and thermal images show the most at once.

What to check before booking

  • Whether VAT is in the quoted price
  • Their drone registration, if they fly one
  • Their report turnaround times
  • What happens after the report arrives

What’s in a roof survey

How a thermal roof survey works in Fernhill

Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there is safe access. We survey ceilings below the roof, pitched roof slopes and commercial roofs, and people most often book us about cold spots on ceilings under the roof and damp around chimneys and parapets.

In a village or hamlet like Fernhill, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what cannot be reached safely. Weather and airspace are looked at before the visit. Older roofs with steep slopes and tall chimneys are where the extra view helps most.

Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the roof, any defects and our written recommendations.

DIY checks: what’s safe

Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.

Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.

FAQs for Fernhill

Is my home in Fernhill listed or in a conservation area?

For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.

Will you come out to Fernhill?

Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there when booking.

What does a thermal roof survey show?

The camera records how the surface temperature varies. Those patterns can point to trapped moisture, missing insulation or heat loss. Findings are checked with moisture readings.

Does the report include photographs?

Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.

Can a thermal survey trace a roof leak?

Thermal imaging can help, alongside other checks. The results depend on conditions on the day. If the source can’t be confirmed, we will say what could help next, such as electronic leak detection.

Can thermal imaging show missing insulation?

It can show temperature patterns that point to missing or thin insulation. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.

What conditions are best for thermal imaging?

The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. We record the conditions in the report, so you know how much weight to give the images.

The survey, step by step

When we arrive, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can safely be seen, from the ground, from windows, in the loft space and by drone where it applies. Most surveys take roughly 1–2 hours on an ordinary house, and more on a big or complicated roof. In a hamlet or village like Fernhill, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.

  1. You let us know about the roof and any damp, leaks or cold rooms.
  2. The weather and surface conditions are recorded.
  3. We inspect the roof and take thermal images during the same visit.
  4. We back up the thermal patterns with moisture readings.
  5. You get the report the same day, with an in-person consultation to follow.

How to prepare

  • Show us where any leaks or stains appear
  • Have keys ready for side gates, garages or roof access doors
  • If you are buying, check with the agent that we can get in

Tips from our surveys

A few practical points come up again and again on our surveys. They apply to most roofs:

  • Make sure the loft can be reached safely
  • Keep outlets and gutters clear to stop water sitting
  • Take photos of stains as they appear, so we can compare
  • Heat the home normally on the days before

If you’re buying, the report gives you specific points to raise with the seller or agent. What you do with it is up to you, whether you ask for work before completion or discuss the price.

Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.

What a thermal roof survey doesn’t cover

This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:

  • What’s inside walls or under coverings, without opening up
  • Reliable images in rain, strong wind or on a wet roof surface
  • A formal energy assessment

If you’re not sure which survey you need, call 07833 053749 or email us and we will give you a straight answer. What a survey covers and does not.

What we check

  • Loft conversions
  • Insulated roof spaces
  • Ceilings below the roof
  • Commercial roofs
  • Flat roofs
  • Pitched roof slopes

Flying and imaging in Fernhill

Older houses across Surrey frequently have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask.

The streets around a church like Church of St Bartholomew are often among the oldest in a place, and if you own one of the older houses nearby, 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. If you run a business near County Mall, thermal images can show trapped moisture across a wide commercial roof.
