What a roof leak investigation does not cover
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- What’s under the covering or behind the plaster
- Structural calculations (that’s a structural engineer’s job)
- Leaks from plumbing, tanks or pipework rather than the roof
If you are not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer. The full list of what we check.

Roof leak investigation in Sunningdale
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Ponding water makes any weakness worse. We check the roof surface and the ceiling below. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. We are often asked to look into stains around a skylight and drips from nail tips in a cold loft, across flat roof details, slate and tile slopes and the roof space.
Chimney stacks on older houses around places like Sunningdale can let water in, through worn flaunching, failed pointing or lifted flashings. Damp on a chimney breast is not always rain from above, which is why it’s worth tracing properly. The stack, its flashings and the loft space beside it are all worth checking.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Different roofs, different checks
Lead flashings
A leak at a flashing frequently shows some way from the joint. That’s why we check the flashings near a stain, not just the one directly above.
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
Roof leak investigations in Sunningdale: local notes
About 4.8 miles north lies St Leonard's Hill, a reminder of how long the area around Sunningdale has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Different coverings let water in at different points, which shapes where the search starts.
Landlords with a home close to Sunningdale station may find that tracing a leak quickly matters when a tenant is living with it. If you live near a park like Silwood Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.

What we are asked to look at in Sunningdale
Condensation is often mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, especially where ventilation is poor. Drips from nails and damp underlay are typical signs.
Typical things we’re asked to look at include:
- Water dripping from rafters or underlay
- Water that shows only in certain storms
- Staining around the chimney inside
- Staining where a gutter or parapet meets the wall
If you live in an older home near Holy Trinity Church, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

Why it’s worth a survey now in Sunningdale
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Arranging work in a smaller place like Sunningdale is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400, both including VAT. You will know the price for your roof before booking.

How it works
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photos go into the written report. It usually takes about 1–2 hours on an ordinary house, or half a day or so for a commercial building. Some parts of a survey depend on the weather, so a visit to Sunningdale is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- 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.
- The report explains the likely entry point and what needs attention.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Tell us about parking before the day
- Leave a clear route to the loft

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Put a bucket under the drip and move valuables
- Check whether pipes or tanks run near the stain
- Record whether it leaks in every downpour or only some
- Make sure the loft is accessible
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. You can ask us about anything that is not clear.
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. Use a professional rather than climbing up yourself.
Sunningdale: your questions answered
Is my home in Sunningdale listed or in a conservation area?
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, and councils can also use Article 4 directions.
Is Sunningdale in the area you cover?
Yes. Our area covers London and the South East, and Sunningdale is part of that. Just ring 07833 053749 or send us an email and tell us about the property, and we will talk through which survey suits.
What should I do before you arrive?
Note when the leak appears and what the weather was doing. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Will you walk on the roof?
Only if it’s safe. We inspect everything that’s safely in view: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
How do I book a survey in Sunningdale?
To book, ring 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
