Roof leak investigations in Windlesham: local notes
If your home is older, it’s worth knowing whether it’s listed or in a conservation area before planning roof work. 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. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
If you live in an older home near Church of St John the Baptist, water on an older roof tends to find its way in at the lead, the valleys or the chimney. Landlords with a home close to Bagshot station may find that a clear finding on where water gets in helps you brief a roofer right away. If you live near a park such as Brentmoor Heath, or anywhere with mature trees, autumn leaves can block gutters and valleys.

Roof leak investigation in Windlesham
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. We check parapets, valleys and flashings from each safe vantage point. Our report shows what we found, with photos. We survey flat roof details, valleys and parapet gutters and slate and tile slopes, and the problems we’re asked to look at most are wet patches on loft insulation and damp ceilings under a flat roof.
Around Windlesham, chimneys on older homes are a common source of leaks, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast is not always rain from above, which is why it is worth tracing properly. It is worth looking at the stack from outside and at the timbers beside it in the loft.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Leave roof access to professionals
- Do not touch fittings that water is reaching
- Photograph the stain each time it appears
- Put a bucket under the drip and move valuables
Any roofer you ask to quote can work from the report. They’ll see exactly where the problem is, rather than at the stain.
Keep gutters, valleys and outlets clear, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
Why get it checked now?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Around Windlesham, leaves and moss in gutters lead to overflowing water and damp walls, particularly where trees overhang. It’s easy to sort the cause early and slow to dry a damp wall.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

How the survey works
We will ask a few questions first, such as when any problem began and what work has been done before. The inspection then takes about 1–2 hours at most homes, while a commercial roof takes nearer three to four hours. In a smaller place like Windlesham, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- 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.
Preparing for the visit
- Let us know about any leaks, stains or damp patches you know of
- Move anything stored under the loft hatch
- If it is not your property yet, arrange access through the agent

Advice
Should I look at the roof myself first?
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
What we look for on each type of roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. We check outlets and the covering around them.
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. Problems there often show in the rooms on the top floor.
For landlords and managing agents
Where a roof is shared: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we will plan the visit with that in mind.
Any of our surveys can be booked by landlords, agents and building managers in Windlesham. For a price for a let property or a block, ring 07833 053749 or send us an email.
Common questions in Windlesham
How do I find out if my home in Windlesham is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you come out to Windlesham?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Does the investigation include the repair?
This service finds and reports the cause, not to carry out the repair. With the report, a roofer knows exactly where to look.
How long have you been surveying roofs?
We have completed more than 5,000 surveys, over more than 20 years.
Could my leak actually be condensation?
It is a common question. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. The report explains which it looks like and what to do.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
