Roof leak investigations for homes and businesses in Sonning
Some ‘leaks’ are not leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, and the stains look much like a leak. Knowing which it is means the right fix can be done, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. If you’ve noticed ceiling stains that grow after rain and water that shows only in certain storms, we can find out what’s behind it.
Being in a small place like Sonning makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. Photographs of the stain and of the roof from outside are helpful too.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Roof leak investigations around Sonning
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Different coverings let water in at different points, which shapes where the search starts. Before planning roof work on an older home, find out whether it is listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
The streets around a church like St Andrew's Church are frequently among the oldest in a place, and if your home is one of the older ones nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. Shop and office owners around The Oracle may find that finding where water is getting in quickly keeps disruption down. Anyone responsible for a site like Sonning Church of England Primary School will know that a leak through a large roof is often found some distance from where the water shows inside.
Sonning is about 1 mile north-west of Woodley, in Reading. Anywhere in Sonning, we can carry out roof leak investigations at your property. Sonning is one of the places in Reading we cover.

Other services in Sonning
Different roofs, different checks
Chimney stacks
Damp on a chimney breast inside frequently starts at the top of the stack. Unused flues with open pots can let rain straight in.
Parapet and box gutters
A butterfly roof drains to a central valley gutter. Problems there frequently show in the rooms on the top floor.
Why get it checked now?
Damp loft insulation loses much of its value. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. For older village homes like those around Sonning, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. Size, height and access can affect the price too.
Why book with us

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we look at the roof.
Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Check whether pipes or tanks run near the stain
- Note the weather when the leak shows
- Let us know what has already been tried
- Photograph the stain each time it appears
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that isn’t clear.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
Questions from Sonning
Do you cover smaller places like Sonning?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Is Sonning in the area you cover?
We do. Every survey there gets the same written report with photos.
Do you look in the loft space?
If there is a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
What does a roof survey cost?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it’s agreed before booking.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. We always check what it shows with moisture readings.
Will you definitely find the leak?
We cannot promise it. Some leaks hide well, particularly those that need wind-driven rain. If we cannot be sure, the report ranks the possible sources.
Is it a leak or condensation?
It’s a common question. A leak normally shows in one area and follows rain, while condensation is often spread out and worse in cold weather. The report explains which it looks like and what to do.
What affects the price in Sonning
Prices vary from roof to roof, for these reasons:
- Roof area
- The package you choose: Basic, Standard or Premium
- How complicated the roof is, with its valleys, chimneys and parapets
- If the survey needs thermal imaging or a drone
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.
What we need to know
The more you tell us, the easier it is to price the survey. When you get in touch, it is useful to mention:
- Photos of the roof, taken safely from the ground or a window
- When you need the report by
- What made you get in touch
- Where water is showing inside, if it is
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or drop us an email to find out.
The survey, step by step
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit normally takes about one to two hours, more where the leak is intermittent or the roof is large. Somewhere as small as Sonning, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
How to prepare
- Let us know about any leaks, stains or damp patches you know of
- Jot down any questions you want answered
- If it is not your property yet, arrange access through the agent
