Thermal roof survey in Langley Green

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. It works best when the building is heated and it’s colder outside. Our report points out what the images suggest and where to look more closely. It is not an energy rating or a heat loss calculation. If you’ve noticed moisture around outlets and upstands and wet insulation beneath the membrane, a survey will tell you what’s going on, on pitched roof slopes, commercial roofs and ceilings below the roof alike.

Around Langley Green, 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, as calm, dry conditions suit both. Even so, a close-up image often shows wear on ridges and flashings that a view from the ground misses.

Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photo. You’ll see the good as well as the bad.

What affects the cost of thermal roof surveys

Prices vary from roof to roof, and it comes down to:

  • Features like valleys, chimneys, dormers and parapets
  • The size of the roof
  • House, block, shop or office
  • The use of thermal imaging or a drone

To find out what your survey will cost, phone 07833 053749 or use the contact form with the address and a few details. The price is agreed before a date is set.

Getting in touch

What helps most when you contact us:

  • Any photos you have, taken from the ground or a window
  • The style of property, from a terrace to a block
  • How the loft is reached, if there is one
  • When you need the report by

To arrange a survey, phone 07833 053749 or send us an email and let us know the address and what’s prompted the survey. You will know the price before anything is booked.

Useful tips for Langley Green property owners

From years of surveys, a few habits stand out as worth the effort:

  • Heat the home normally on the days before
  • Keep dated photos of any marks on ceilings
  • Check outlets after heavy rain
  • Clear a path to the loft hatch before we arrive

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.

Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.

What we do, step by step

The aim of the visit is simple: 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. It typically takes roughly 1–2 hours for a house, though large, tall or awkward roofs take more time. In a smaller place like Langley Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from the ground, with the loft showing the underside, while taller roofs may need other vantage points or the drone where applicable.

  1. First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
  2. We carry out a visual inspection of the roof from wherever it can safely be seen.
  3. Thermal images are taken to show differences in surface temperature.
  4. Any patterns of interest are checked with moisture readings where we can reach them.
  5. You get a report with thermal images, photos and our recommendations.

How to prepare

  • Make sure we can get to the back of the property
  • Mention any parking restrictions on your street
  • Find any records of previous roof work

Flying and imaging in Langley Green

Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.

For businesses in and around places such as County Mall, a commercial roof can be photographed from above without anyone walking on it. The streets around a church like Voice of Deliverance Full Gospel Church of God are frequently among the oldest in a place, and if yours is one of the older homes nearby, older roofs can be steep and hard to see from the street, which is where aerial photos and thermal images help. For hotels and guest houses around Langley Green, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

Questions from Langley Green

Are there drone restrictions around Langley Green?

That depends on where the roof is and on the weather. Langley Green is inside, or right on the edge of, the flight restriction zone around Gatwick Airport. We ask the airport for permission before flying there, and only fly if it’s given. The flight also waits for calm, dry weather, and the rest of the survey does not depend on the drone.

Will you come out to Langley Green?

Yes. Langley Green is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.

How long is the visit?

That depends on the size and shape of the roof, but most surveys take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. The written report follows by email.

How long have you been surveying roofs?

Over 20 years and more than 5,000 surveys, across London and South East England.

Do you survey roofs on blocks of flats?

Yes, as long as access is agreed. Roofs over flats are often shared, so the building owner or managing agent needs to agree access. We inspect only the parts we are allowed to reach.

Will I get photos?

Yes. Photographs are taken throughout the survey, and they go into the written report.

How do I arrange a thermal roof survey in Langley Green?

To book, ring 07833 053749 or use the contact form and let us know the address and what you want to find out. We will confirm the price and find a day that suits.

Rented homes, blocks and businesses

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.

Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant ahead of time.

Different roofs, different checks

Felt and asphalt flat roofs

Felt and asphalt roofs often show wet areas as patches that differ from the rest. We check those patches with moisture readings.

Parapets, valleys and junctions

Parapet and valley gutters can overflow inside a building. We use the camera and moisture readings to help follow it.

What we can’t see

Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:

  • An energy rating for the building
  • Structural calculations, which need a structural engineer
  • Hidden layers that need to be opened up to check
