Signs you need a roof leak investigation in Ascott-under-Wychwood
Valleys carry a lot of water. Split linings, slipped valley tiles or debris can send that water under the coverings. The stain may appear well away from the valley itself.
People normally book a survey when they’ve noticed something like this:
- Leaks that appear only in driving rain
- Damp patches next to the stack
- Brown rings on upstairs ceilings
- Water through the ceiling under a flat roof
Take an older house close to Church of the Holy Trinity: the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Which limits apply to the survey
- What experience they bring
- Whether they hold professional indemnity and public liability insurance
Roof leak investigation in Ascott-under-Wychwood: what you get
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot, along with any photos you’ve taken. Even on a dry day, a leak normally leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. Common reasons to book are damp patches next to the stack and leaks at a dormer or roof window, on flat roof details, slate and tile slopes and rooflights and dormers.
Roofs in small places like Ascott-under-Wychwood frequently stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
The written findings come 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.

Common questions in Ascott-under-Wychwood
How do I find out if my home in Ascott-under-Wychwood is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Do you cover smaller places like Ascott-under-Wychwood?
Yes, Ascott-under-Wychwood is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak normally shows in one area and follows rain, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
Will you definitely find the leak?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but some only appear in certain weather. We report what we found and the likeliest sources.
Why is not the leak directly above the stain?
Because water travels. It runs along rafters, battens or underlay before it drips, so the stain may be some distance from where it gets in. That is why we trace the route rather than patching above the stain.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. We’ll talk about access when booking.
DIY checks: what’s safe
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. Leave anything above ground level to a survey.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How we price roof leak investigations
A few things affect what a survey costs:
- Roof area
- How complicated the roof is, with its valleys, chimneys and parapets
- Commercial roofs and larger buildings
- Any need for thermal images or a drone flight
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400, both with VAT included. You will know the price for your roof before booking.
Helping us price your survey
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- The address and postcode of the property
- Anything about access we should know
- Any deadline, like an exchange date
- Where any leaks, stains or damp patches show inside
Photos help, if you have them. Take them safely from the ground or a window. To get started, ring 07833 053749 or send us an email.
What we look for on each type of roof
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, and water runs down behind them.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Water then gets in along the top of the roof.
The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours, more where the leak is intermittent or the roof is large. Rural addresses near Ascott-under-Wychwood can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You tell us where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- Find any records of previous roof work
- Tell us about parking before the day
Arrange a survey
We confirm the price for your roof before you book, so you know where you stand. Roof leak investigation starts from £150, including VAT. For a price for your roof, call 07833 053749 or drop us an email.
Advice
Tips from our surveys
Small things make a difference. Our tips:
- Don’t climb onto the roof to look
- Write down the wind direction and rain when it leaks
- Mention any plumbing above the damp area
- Put a bucket under the drip and move valuables
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, so the repair is aimed at the cause.
Don’t block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Check insulation doesn’t block airflow at the eaves.
