Thame Roof Leak Investigation
We carry out roof leak investigations in Thame and the rest of Oxfordshire. Surveys run on weekdays and at weekends.
- Water coming in around a roof light or dormer
- A leak that comes and goes with the weather
- Staining around the chimney inside
What we look for on each type of roof
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
Parapet and box gutters
Linings, joints and outlets are inspected wherever it’s safe, and look for signs of past overflowing.
Roof leak investigation in Thame
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. We survey slate and tile slopes, valleys and parapet gutters and rooflights and dormers, and the problems we’re asked to look at most are damp on a chimney breast and leaks that appear only in driving rain.
Extensions, dormers and conservatories are common on houses in towns like Thame, and the joint between new and old is a classic place for water to get in. The flashings and upstands at those joints get a careful look. The stain inside is often some way from where water gets in, particularly around extensions.
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.

How we price roof leak investigations
The price reflects the time and kit the roof needs. That comes down to:
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- The package you choose: Basic, Standard or Premium
- How big the roof is
For a price for your roof in Thame, call 07833 053749 or send us an email with the address and some details. The price is agreed before a date is set.
Getting in touch
A little information up front helps. It is useful to include:
- What kind of property and roof it is
- Anything about access we should know
- The address and postcode of the property
- The reason for the survey, such as buying, a leak or storm damage
You can call us seven days a week. To book or ask a question, ring 07833 053749 or use the contact form.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Don’t climb onto the roof to look
- Write down the wind direction and rain when it leaks
- Photograph the stain each time it appears
- Clear the loft hatch so we can get in
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
Thame roofs and the weather
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. The covering and its details give the first clues when tracing where water is coming from. Adwell House, about 3.9 miles south, is one of the historic houses in the wider area around Thame. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Hotels and guest houses near Thame cannot easily close rooms for a leak, so it pays to find faults before guests do. Landlords with a home close to Haddenham & Thame Parkway station may find that a clear finding on where water gets in helps you brief a roofer right away. Take a building like Barley Hill Primary School: a leak through a large roof is often found some distance from where the water shows inside.
Thame is about 8 miles south-west of Aylesbury, in Oxfordshire. Roofs in Thame get the same thorough look as anywhere else in Oxfordshire. Thame is one of the places in Oxfordshire where we work for roof leak investigations. Our Oxford page covers surveys nearby.
We cover every part of OX9 for roof leak investigations. You’ll find streets such as Upper High Street, Butter Market and High Street, all of which we cover. With the A329 and A418 close by, Thame is easy for us to reach for roof leak investigations. Neighbouring places we cover for roof leak investigations include Moreton (1 mile south-west), Towersey (1 mile east), Kingsey (2 miles east), Long Crendon (2 miles north-west) and Haddenham (3 miles north-east).

Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Let us know about it when booking and we’ll plan the survey around it.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Your questions about roof leak investigations in Thame
How should I get ready for a visit in Thame?
The main thing is access, inside and out, plus somewhere to park in Thame. Tell us about known leaks or past repairs as well.
Is Thame in the area you cover?
We do. The survey and report are the same in Thame as anywhere else.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
How it works
Once we’ve finished looking, we write up our findings as a photo-illustrated written report. As for time on site, most surveys take between one and two hours on an ordinary house; commercial roofs usually need 3–4 hours. In Thame, parking is rarely complicated, though it helps to know about driveways or restrictions. The inspection covers everything that’s safely in view from outside, from windows and from the roof space, and from the roof itself where it’s safe.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- If you’re buying, check with the agent that we can get in
- Tell us where we can park nearby
Book a survey
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, call 07833 053749 or use the contact form.

What you can safely check yourself
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
