What we’re asked to look at in Denchworth
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. Once that seal cracks or lifts, water gets behind it.
People typically book a survey after spotting something like this:
- Drips in the loft during heavy rain
- Staining around the chimney inside
- Leaks that appear only in driving rain
- Leaks below a flat extension roof
Take an older house close to Church of St James: water on an older roof tends to find its way in at the lead, the valleys or the chimney.

About our roof leak investigation in Denchworth
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. Each one is checked from wherever it is safe to see it. We survey chimney stacks, flat roof details and lead flashings, and common reasons people get in touch are water that shows only in certain storms and leaks at a dormer or roof window.
Roofs in small places like Denchworth frequently stand in the open, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What we look for on each type of roof
Lead flashings
Some roofs have mortar where you’d expect lead. They crack as the roof and wall move, and water runs down behind them.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it is too low, cracked or poorly dressed, water gets behind it.
For landlords and managing agents
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey seven days a week, which helps when tenants work during the week.
Landlords, agents and building managers in Denchworth and across Oxfordshire can book any of our surveys. For a price for a let property or a block, ring 07833 053749 or send us an email.
What a survey costs
Prices vary from roof to roof, and it comes down to:
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
- The package you choose: Basic, Standard or Premium
- Height and safe access
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
Booking your survey
You do not need to know any roofing terms. It’s enough to tell us:
- How the loft is reached, if there is one
- What’s prompted the survey
- Your postcode, so we can check access and travel

Questions from Denchworth
Will you come out to Denchworth?
Yes. Denchworth is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is my home in Denchworth listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you fly a drone over my roof?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed as you book.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What happens after the survey?
You’ll get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
How do I book a survey in Denchworth?
Just ring 07833 053749 or use the contact form. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
What a roof leak investigation looks like in Denchworth
About 4.7 miles north lies Longworth House, a reminder of how long the area around Denchworth has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. The covering and its details give the first clues when tracing where water is coming from.

What happens if roof problems are left?
A leak that returns after a repair typically means the real source wasn’t found. We look past the obvious spot and check each likely route. That is frequently what breaks the cycle. Older cottages and farmhouses around Denchworth can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.

Time on site depends on the size and shape of the roof, but as a rough guide the survey takes an hour or two on an ordinary house, and longer for a large or complex roof.

We work round each section in turn, from the safest viewpoints.

- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
