Harpsden questions
Do you carry out roof surveys in Harpsden?
Yes, Harpsden is within the area we cover. Our area covers London and the South East. You can call 07833 053749 or send us an email with the address and some details.
How do I find out if my home in Harpsden is listed?
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.
How long will you be at the property?
It usually takes about one to two hours at a typical home, rising to roughly 3–4 hours on a commercial building. You will then get the report by email, on the timescale of your package.
What’s in the survey report?
Written findings with photos, covering the condition of the roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Is thermal imaging good for finding leaks?
It can help narrow down where water may be getting in. Water can travel under a covering before it shows inside, and temperature patterns can help follow it. We combine it with a visual inspection and moisture readings because the camera cannot confirm water on its own.
Does thermal imaging detect leaks directly?
Thermal imaging shows temperature rather than water. Wet insulation holds heat longer than dry, so it can stand out, but we check each finding with moisture readings.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
How a thermal roof survey works in Harpsden
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. Patterns can suggest where water is trapped under the covering. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we also look from the loft where we can reach it safely. Common reasons to book are missing or slipped insulation and cold spots on ceilings under the roof, across pitched roof slopes, insulated roof spaces and flat roofs.
Somewhere as small as Harpsden, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what can’t be reached safely. Weather and airspace are checked before the visit, and the journey is planned beforehand. Steep slopes and tall chimney stacks are where a close-up view adds the most.
You receive the findings by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

If you own several properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or drop us an email.
Any of our surveys can be booked by landlords, agents and building managers in Harpsden. To discuss a property or a block, call 07833 053749 or send us an email.
What happens if roof problems are left?
Thermal images can suggest the extent of wet areas without cutting into the roof. That helps you and your roofer decide what really needs replacing. For older village homes like those around Harpsden, the right replacement materials are not always easy to find quickly. That’s one more reason to find defects before they become urgent.

Thermal roof surveys in Harpsden: local notes
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
If you run a hotel or guest house in or near Harpsden, a roof problem can mean rooms out of use, so it pays to find faults before guests do. With Greys Court about 2.8 miles north-west, the area around Harpsden has a long history. Older roofs nearby can be steep and hard to see from the ground, and a survey from the air or with a thermal camera does not touch the roof itself. For site and facilities teams at buildings such as Trinity Church of England Primary School, a view from above covers a wide roof far faster than walking it.
Harpsden is about 4 miles north-east of Caversham, in Oxfordshire. From houses to flats and shops in Harpsden, the roof can be surveyed. Across Oxfordshire, we cover Harpsden and the places around it. Our Reading page covers surveys nearby.

What we look for on each type of roof
Parapets, valleys and junctions
Damp at junctions can be hard to see by eye. A careful visual inspection goes alongside the images.
Single-ply and EPDM roofs
Because these membranes are thin, patterns from below often show. Reflections from shiny surfaces can affect readings, which we allow for.
How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes between one and two hours for most houses, with bigger or more complicated roofs taking longer. Somewhere like Harpsden needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- The report pairs each thermal image with a photo and explains what it suggests.
How to prepare
- Keep pets out of the way during the survey
- Have keys ready for side gates, garages or roof access doors
- Leave a clear route to the loft
Arrange a survey
Prices start from £400, including VAT. The exact figure depends on the roof and the package, and you can phone 07833 053749 or drop us an email to find out.
Advice
DIY checks: what’s safe
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.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.

Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Hidden layers that need to be opened up to check
- A formal energy assessment
- Structural calculations, which need a structural engineer
