Roof leak investigations for homes and businesses in Highmoor
The aim is to find where the water is getting in and explain it. You get a photo-illustrated written report showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, while the repair is a separate matter. We survey the roof space, valleys and parapet gutters and flat roof details, and people most frequently book us about leaks below a flat extension roof and staining around the chimney inside.
For a small place like Highmoor, the inspection is the same as anywhere: the journey and access are just planned ahead of time. Tell us where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. If you have photographs of the water coming in, they help as well.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Signs you need a roof leak investigation in Highmoor
A chimney stack has lots of places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. It can show up on the chimney breast, nearby ceilings or in the roof space.
Common reasons to book include:
- Leaks that appear only in driving rain
- Wet patches high on an inside wall
- Brown rings on upstairs ceilings
- Wet patches on loft insulation
If you own one of the older houses in the streets near Church of St Paul, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
What to check before booking
- Will the report include photos?
- Whether they hold professional indemnity and public liability insurance
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Do they have a CAA Flyer ID and Operator ID for drone work?
Honest limits
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Plumbing leaks that look like roof leaks
- Structural calculations (that’s a structural engineer’s job)
- Leaks that only appear in weather we can’t recreate
If in doubt, call 07833 053749 or drop us an email and we’ll recommend the right survey. What our survey covers.
What this survey covers

What a roof leak investigation looks like in Highmoor
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Where water gets in depends a good deal on what the roof is made of and how it is detailed. With Greys Court about 2 miles south-east, Highmoor sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Henley-On-Thames station may find that tracing a leak quickly matters when a tenant is living with it. For site and facilities teams at buildings such as Stoke Row Church of England School, on a building that size, finding the source of a drip means looking well beyond the stain.
Highmoor is about 4 miles north-west of Henley-on-Thames, in Oxfordshire. Houses, flats, blocks and commercial buildings in Highmoor can all book roof leak investigations. Our area takes in places right across Oxfordshire. We also survey roofs in Reading.

What affects the cost of roof leak investigations
Prices vary from roof to roof, for these reasons:
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- The number of roofs, including extensions and garages
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 with VAT included. We can help you choose the package that fits what you want to find out.
What we need to know
When you call or email, these details help:
- The property’s address and postcode
- Where any leaks, stains or damp patches show inside
- The style of property, from a terrace to a block
- Any deadline, such as an exchange date
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or use the contact form whenever suits you.

What else we do in Highmoor
Roof by roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. Outlets and the area around them are checked.
Chimney stacks
Damp on a chimney breast inside frequently starts at the top of the stack. Open, unused pots let rain fall down the flue.
Common questions in Highmoor
Do you cover smaller places like Highmoor?
Yes, Highmoor is covered. Our area covers London and South East England, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.
Does a conservation area affect roof work in Highmoor?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
What will the report tell me?
Written findings with photographs, covering the condition of the leaking 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.
How do I book a survey in Highmoor?
To arrange a survey, phone 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Why is not the leak directly above the stain?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it shows. Tracing that path is the heart of a leak investigation.
Will I get photos?
Yes. The report includes photos of what we found, so you can see each point for yourself.
How the survey works
Every roof is different, but as a rough guide the survey takes about one to two hours for most homes, though a hard-to-trace leak can take longer. If you have questions on the day, just ask. In a small place like Highmoor, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Jot down any questions you want answered
- Keep pets out of the way during the survey
- Let us know about any leaks, stains or damp patches you know of

Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
