About our roof leak investigation in Sunninghill
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. Telling the two apart matters, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. We are often asked to look into water dripping from rafters or underlay and damp on a chimney breast, on flat roof details, slate and tile slopes and rooflights and dormers.
Around Sunninghill, chimneys on older homes are a common source of leaks, at the flashings, the pointing or the mortar round the pots. Damp in a chimney breast can have more than one cause, so it is not always obvious where it starts. It is worth looking at the stack from outside and at the timbers beside it in the loft.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Do you need a roof leak investigation in Sunninghill?
Condensation is often mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly where ventilation is poor. Wet nail tips and damp underlay over a wide area are classic signs.
A survey can pick up problems like:
- Water coming in around a roof light or dormer
- Water that shows only in certain storms
- Wet patches high on an inside wall
- Drips in the loft during heavy rain
The streets around a church such as Church of St Michael and All Angels 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.
What to check before booking
- How they plan to inspect the roof safely
- Their report turnaround times
- What the survey won’t cover
- What the report includes, and whether it has photos
Tips that help
A little preparation and a few simple habits help. Our tips:
- Put a bucket under the drip and move valuables
- Clear the loft hatch so we can get in
- Check whether pipes or tanks run near the stain
- Don’t touch fittings that water is reaching
If condensation is the cause, we explain it, and suggest how the roof space could be better ventilated. That avoids roof work that wouldn’t help.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.

Common questions in Sunninghill
How do I find out if my home in Sunninghill is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Will you come out to Sunninghill?
Yes, Sunninghill is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Will you go up on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days as you book.
Is this an asbestos survey?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
Do you use drones?
Yes, where it applies and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to, and the report makes that clear.
What happens if roof problems are left?
Patching the spot above the stain often does not work. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first, so the repair is aimed at the right place. Blocked gutters on homes around Sunninghill overflow and soak walls. It is easy to sort the cause early and slow to dry a damp wall.
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

Roof leak investigations around Sunninghill
Historic houses such as St Leonard's Hill, about 4.6 miles north, show how far back building in the area around Sunninghill goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. The covering and its details give the first clues when tracing where water is coming from.
Landlords with a home close to Ascot station may find that tracing a leak quickly matters when a tenant is living with it. If you look after a building like St Michael's CofE Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.

How it works
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes roughly 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. Being in a smaller place like Sunninghill does not change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- We help you choose the package that suits the leak.
- 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.
- The report explains the likely entry point and what needs attention.
How to prepare
- Jot down any questions you want answered
- Have keys ready for side gates, garages or roof access doors
- Make sure the loft hatch can be reached
