How we price roof leak investigations
Not every roof costs the same to survey, and it comes down to:
- How big the roof is
- The shape of the roof and its details
- If the survey needs thermal imaging or a drone
- How many separate roofs there are, like extensions, dormers and garages
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. The roof’s size, height and access matter as well.

About our roof leak investigation in East Barnet
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. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. An ageing felt roof is a frequent culprit. We survey rooflights and dormers, the roof space and slate and tile slopes, and the problems we’re asked to look at most are a leak that comes and goes with the weather and wet patches high on an inside wall.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers normally exclude wear and tear. That is as true in East Barnet as anywhere in London. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

What you can safely check yourself
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Leaks and storm damage in East Barnet
With Heath Hall about 4.2 miles south, East Barnet sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. The covering and its details give the first clues when tracing where water is coming from.
Take a building like Church Hill School: on a building that size, finding the source of a drip means looking well beyond the stain. For businesses in and around places such as Grand Arcade, a quick answer on where water is coming in keeps a business running. Trees in and around Oak Hill Park shed leaves that can end up in nearby gutters.

How the survey changes by roof type
Valleys
Stains from a valley leak often show some distance off. From inside the loft space, we follow the water’s route back.
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
FAQs for East Barnet
How do I find out if my home in East Barnet 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.
Can parking be tricky for a visit in East Barnet?
It can be, so it helps to let us know about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
How do you tell a leak from condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We look at the pattern, take moisture readings and tell you which is more likely.
Does the investigation include the repair?
The investigation is about finding the cause. The repair isn’t part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
How long will you be at the property?
Allow an hour or two on an ordinary house, with bigger or more complicated roofs taking longer. We’ll confirm what to expect when we arrange the visit.

Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Whether rotten timbers meet design loads
- What’s under the covering or behind the plaster
- Putting the leak right
If in doubt, phone 07833 053749 or email us and we’ll point you to the right survey. The full list of what we check.
Roofs we survey in East Barnet
- The roof space
- Slate and tile slopes
- Chimney stacks
- Flat roof details
- Lead flashings
- Rooflights and dormers
- Valleys and parapet gutters
What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take about 1–2 hours, more where the leak is intermittent or the roof is large. From the street, a London terrace usually shows only its front slope or parapet, so a visit in East Barnet moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- 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.
How to prepare
- Have any questions written down, so nothing gets missed
- Keep pets out of the way during the survey
- Gather any invoices or paperwork from past roof work
