How a roof leak investigation works in Bagshot
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We look at the roof surface and the ceiling below. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey lead flashings, slate and tile slopes and chimney stacks, and the problems we’re asked to look at most are water dripping from rafters or underlay and drips from nail tips in a cold loft.
Roofs in small places like Bagshot frequently stand in the open, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photos show what each point refers to.

Roof leak investigations in Bagshot: local notes
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Different coverings let water in at different points, which shapes where the search starts. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
Anyone responsible for a site like John O'Gaunt School will know that on a building that size, finding the source of a drip means looking well beyond the stain. If you own a rental within reach of Bedwyn station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

Common questions in Bagshot
Is Bagshot in the area you cover?
Yes. We work right across London and South East England, and Bagshot is part of that. You can phone 07833 053749 or drop us an email with the address and some details, and we will talk through which survey suits.
Do you cover smaller places like Bagshot?
We do. A small place gets exactly the same survey as a big one.
How soon will I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Will I get photos?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
Will you go up on the roof?
Only if it’s safe. We look at everything that can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
DIY checks: what’s safe
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Roof by roof
Lead flashings
A leak at a flashing often shows some way from the joint. That is why we check the flashings near a stain, not just the one directly above.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
How the survey works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely. Most surveys take about 1–2 hours for most houses, with bigger or more complicated roofs taking longer. Somewhere like Bagshot needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Mention any parking restrictions on your street
- Keep pets inside or away from the areas we’re looking at
- For flats, check roof access has been agreed
Booking a survey
If you are buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or send us an email whenever suits you.

How we price roof leak investigations
Not every roof costs the same to survey, for these reasons:
- Extensions, dormers and garages with roofs of their own
- Which survey package you book
- Chimneys, valleys, parapets and other details
- How tall the building is and how easy the roof is to see
Roof leak investigation starts from £150, including VAT. The final price depends on the size and height of the roof, how it can safely be seen and the package you choose.
Helping us price your survey
When you call or email, these details help:
- The reason for the survey, like buying, a leak or storm damage
- Any marks or damp showing indoors
- The kind of building and roof involved
- The property’s address and postcode
Our phone lines are open seven days a week. For a price or to book, ring 07833 053749 or email us.
What this survey cannot tell you
Some things can’t be seen without opening up the roof, and that sets some limits:
- Putting the leak right
- What’s under the covering or behind the plaster
- A promise to find every leak on a single visit
If in doubt, call 07833 053749 or send us an email and we’ll suggest the right survey before you book. The full list of what we check.
Roof types and parts we check
- The roof space
- Rooflights and dormers
- Chimney stacks
- Flat roof details
- Lead flashings
- Slate and tile slopes
- Valleys and parapet gutters
When to book a survey in Bagshot
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
Here are some of the things we see frequently:
- Water marks that spread in wet weather
- Water dripping from rafters or underlay
- Damp ceilings under a flat roof
- Drips from nail tips in a cold loft
The streets around a church such as Church of the Good Shepherd are often among the oldest in a place, and if you own one of the older houses nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- When you’ll get the report
- Whether the loft space is looked at, where there is one
