Chilson Roof Leak Investigation
Roof leak investigations in Chilson from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us.
- Damp on a chimney breast
- Leaks that appear only in driving rain
- Stains around a skylight
Roof by roof
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
Roof leak investigations for homes and businesses in Chilson
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. We look at all of them, from every safe vantage point. We survey lead flashings, the roof space and valleys and parapet gutters, and common reasons people get in touch are a leak that comes and goes with the weather and damp underlay across a wide area.
Many homes in small places like Chilson face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
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.

Your questions about roof leak investigations in Chilson
Does a conservation area affect roof work in Chilson?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover Chilson?
We do. The survey and report are the same in Chilson as anywhere else.
Will you fix the leak as part of this?
Our job here is to trace the leak and explain it, and the repair is separate. With the report, a roofer knows exactly where to look.
Does someone need to be in?
Not always. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Could my leak actually be condensation?
The two can look alike. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We look at the pattern, take moisture readings and tell you which is more likely.
How much does a roof leak investigation cost in Chilson?
Our price is from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
Can you always find the source?
Not always, and we’ll be honest about that. Water can travel a long way, and some leaks only show in particular storms. Where the source is not certain, we list the likely routes in order.

Chilson roofs and the weather
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. 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. Each of these roof types has its own typical places for water to get in.
If you let a flat or house near Ascott-Under-Wychwood station, a clear finding on where water gets in helps you brief a roofer straight away. If you live in an older home near Church of All Saints, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

What you can safely check yourself
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
It is useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book.
What happens on the day
Once we have finished looking, we write up our findings in a report with photographs, sent to you by email. As for time on site, most surveys take roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Somewhere like Chilson needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Keep pets inside or away from the areas we’re looking at
- Unlock side gates and any roof access doors
- Tell us about parking before the day
Arrange a survey
If you’re buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.

What affects the cost of roof leak investigations
When we price a survey, we consider:
- The height of the building and how the roof can safely be seen
- Any need for thermal images or a drone flight
- Whether you choose the Basic, Standard or Premium Survey
- The roof’s overall size
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
