Bower Heath: your questions answered
Can you fly a drone over a roof in Bower Heath?
That depends on where the roof is and on the weather. Bower Heath is about 1 mile from the edge of the flight restriction zone around Luton Airport. The exact boundary is checked for each address before any flight, and a roof inside it needs permission before we fly. A small drone cannot fly safely in strong wind or a downpour.
Is my home in Bower Heath listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
What do I do with the report?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How long does the survey take?
Time on site depends on the roof, but most surveys take roughly 1–2 hours for a house; commercial roofs usually need 3–4 hours. The written report follows by email.
Will the camera show exactly where the water is?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
What’s the best way to book?
To arrange a survey, call 07833 053749 or use the contact form and tell us the address and what you’d like to know. We will confirm the price and agree a day with you.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Thermal roof survey in Bower Heath
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. There is a 12-month follow-up as well. If you’ve noticed thin or uneven insulation in the roof and water that travels before it shows, a survey will tell you what’s going on.
Some older homes in villages like Bower Heath are listed or in a conservation area. Neither a drone survey nor a thermal survey involves any work on the roof, so it is a gentle way to see the condition of an old roof, before anyone decides what work it needs. Changes that affect a listed building’s special interest need listed building consent, so check with the council first.
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.

How the survey changes by roof type
Felt and asphalt flat roofs
These coverings sit directly on the layers beneath, so temperature differences often show through. Any patterns are checked with moisture readings.
Parapets, valleys and junctions
Problems where roof slopes and walls meet are frequently hidden. A careful visual inspection goes alongside the images.
When to book a survey in Bower Heath
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. A thermal survey, checked with moisture readings, can give a much clearer picture.
It is worth booking a survey if you’ve seen:
- Cold spots on ceilings under the roof
- Wet areas near outlets and upstands
- Heat escaping through the roof
- Wet insulation beneath the membrane
For an older house near a landmark such as All Saints, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.
Before booking any roof surveyor
- What happens after the report arrives
- Will they check the loft as well as the outside?
- Which parts of the roof they’ll actually see
- How soon the report will arrive
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Ask us about the forecast if rain is expected
- Clear a path to the loft hatch before we arrive
- Check outlets after heavy rain
- Leave the roof to people with safe access
If the images suggest moisture that cannot be confirmed, we will say what would help next, for instance electronic leak detection or a roofer opening up a small section.
Keep outlets and gutters clear so water drains off the roof quickly. The less water sits, the less can find its way beneath.

Drones, thermal imaging and Bower Heath roofs
Shaw's Corner, about 3.2 miles east, is one of the historic houses in the wider area around Bower Heath. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. The flight restriction zone around Luton Airport comes within about 1 mile of Bower Heath. Where the drone is part of the survey, we check the exact boundary for the address before flying.
If you look after a building such as Sauncey Wood Primary School, big roofs are where photos from the air and thermal images show the most at once.

Landlord and commercial surveys in Bower Heath
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the visit with that in mind.
We survey roofs for landlords and letting agents as well as homeowners. A photo-illustrated written report gives you a clear record of the roof, useful for planning maintenance.
What affects the cost of thermal roof surveys
Survey packages start from £150, including VAT. What you pay for your roof depends on:
- Building height and the viewpoints available
- Extensions, dormers and garages with roofs of their own
- Features like valleys, chimneys, dormers and parapets
- The size of the roof
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.
Helping us price your survey
Getting the details right at the start saves time. Please include:
- Any photos you have, taken from the ground or a window
- The address and postcode of the property
- When you need the report by
- The reason for the survey, such as buying, a leak or storm damage
Unsure which package suits your roof? It is easiest to phone 07833 053749 or send us an email and describe the roof and why you want it surveyed. We’ll explain the options and the price.
How it works
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take between one and two hours on an ordinary house, with bigger or more complicated roofs taking longer. Older rural homes like those around Bower Heath can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We go through the roof, the problem and the weather expected on the day.
- We look over the roof from wherever it is safe.
- We take thermal images of the roof and of the loft where we can reach it.
- Patterns that stand out are checked with moisture readings.
- The report pairs each thermal image with a photo and explains what it suggests.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Have keys ready for side gates, garages or roof access doors
- Jot down any questions you want answered
