How a roof leak investigation works in Arnos Grove
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. It gives any roofer a clear brief. We find and report the source, while the repair is a separate matter. We survey the roof space, lead flashings and flat roof details, and people most often book us about wet patches high on an inside wall and condensation that looks like a leak.
In London, leaks frequently start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you’re tracing a leak or recording storm damage in Arnos Grove, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Questions from Arnos Grove
How do I find out if my home in Arnos Grove is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can parking be tricky for a visit in Arnos Grove?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
What do I do with the report?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Will you check the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps.
How long does a roof leak investigation take?
The visit usually takes between one and two hours for a house, and more on a big or complicated roof. We will give you an idea of timing as you book.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Leave it or get it looked at?
Water and electrics don’t mix. If water is reaching a light fitting or switch, keep clear of it and have an electrician check it. Then the source needs tracing. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
Every price we give includes VAT, and the written report is part of the package. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

What happens on the day
We will ask a few questions first, 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. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- If you are buying, check with the agent that we can get in
- Jot down any questions you want answered

Arnos Grove roofs and the weather
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Bruce Castle, about 2.6 miles south-east, is one of the historic houses in the wider area around Arnos Grove. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years.
If you run a business near The Mall Wood Green, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. If you live near a park such as Broomfield Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.
Arnos Grove is about 3 miles north-east of Finchley, in Greater London.

What we’re asked to look at in Arnos Grove
A gutter that overflows can soak a wall and mark the ceiling inside. 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:
- Leaks that appear only in driving rain
- Wet patches on loft insulation
- Damp patches next to the stack
- Water marks that spread in wet weather
For site and facilities teams at buildings like Bowes Primary School, tracing a leak on a big roof starts with where the water appears and works back.
Questions to ask before you book
- When you’ll get the report
- Will the report include photos?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What follow-up you get after the report
Checking the roof from the ground
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check whether pipes or tanks run near the stain
- Make sure the loft is accessible
- Keep water away from lights and sockets
- Mention earlier attempts to fix the leak
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Photograph anything new.
