Roof leak investigation in Blackheath: what you get
We investigate roof leaks in Blackheath and across London and the South East. We visit on weekdays, Saturdays and Sundays. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. You get a written report with photos and recommendations. If it’s leaking right now, contain the water and keep it clear of electrics, then call 07833 053749 or email us. Typical surveys look at leaks at a dormer or roof window and staining around the chimney inside, across rooflights and dormers, flat roof details and slate and tile slopes.
Somewhere as small as Blackheath, older roofs have often been repaired many times. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, particularly to an insurer. We check everything that’s safely in view and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Signs you need a roof leak investigation in Blackheath
Flat roofs fail with age and wear. A felt roof often lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Upstands and outlets are common weak points.
Problems we come across often include:
- Condensation that looks like a leak
- Wet patches on loft insulation
- Leaks that appear only in driving rain
- Damp on a chimney breast
Take an older house close to Church of St Martin: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- Which viewpoints they use to see the roof
- How soon the report will arrive
- Their track record with similar roofs
What a roof leak investigation looks like in Blackheath
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Knowing the roof type helps narrow down where water may be getting in. Chilworth Manor, about 1.1 miles north, is one of the historic houses in the wider area around Blackheath. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Anyone responsible for a site like Chilworth CofE (Aided) Infant School will know that tracing a leak on a big roof starts with where the water appears and works back. Landlords with a home close to Chilworth station may find that a tenant living with a leak needs the cause found, not just the stain painted over.
Blackheath is about 4 miles south-east of Guildford, in Surrey. In Blackheath, as across Surrey, every roof gets the same careful survey. We cover towns and villages across Surrey, large and small.

Leave it or get it looked at?
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it’s harder to clear. Stopping the water is the first step. Older cottages and farmhouses around Blackheath can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.

Blackheath questions
Do you cover Blackheath?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Blackheath listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How many surveys have you done?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
Does the investigation include the repair?
This service finds and reports the cause, and the repair is separate. With the report, a roofer knows exactly where to look.
How much does a roof leak investigation cost in Blackheath?
Roof leak investigation starts from £150, including VAT. The final figure depends on the roof and the package you choose.
Can you inspect my roof with a drone?
Where it is applicable and safe, yes. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
Are you insured?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
Before and after the survey
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Tell us if there are tanks or pipes in the loft
- Let us know about any past repairs to the roof
- Protect furniture and flooring under the leak
- Stay off ladders and the roof
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two for most homes, though a hard-to-trace leak can take longer. Rural addresses near Blackheath can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Unlock side gates and any roof access doors
- Point out any leaks or damp patches
- Make sure pets are kept safely away

If you are buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.
