Roof leak investigation in North Finchley: what you get
The aim is to find where the water is getting in and explain it. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. Common reasons to book are stains around a skylight and wet patches high on an inside wall, on rooflights and dormers, the roof space and valleys and parapet gutters.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. In North Finchley, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What affects the cost of roof leak investigations
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- The use of thermal imaging or a drone
- The height of the building and how the roof can be seen safely
- The shape of the roof and its details
- Which survey package you book
Roof leak investigation starts from £150, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.
What we need to know
When you call or email, these details help:
- Your postcode, so we can check access and travel
- The style of property, from a terrace to a block
- The reason for the survey, like buying, a leak or storm damage
- Anything about access we should know
Unsure which package suits your roof? The easiest way is to call 07833 053749 or use the contact form and describe the roof and what’s worrying you. We will explain the options and the price.
North Finchley: your questions answered
Will parking be an issue for a roof survey in North Finchley?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is North Finchley in the area you cover?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
How experienced are you?
Over 20 years and more than 5,000 surveys.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Do you look in the roof space?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Landlords, agents and block managers in North Finchley
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Letting agents can arrange access with tenants, at a time agreed beforehand. We survey seven days a week, which helps when tenants work during the week.
Useful tips for North Finchley property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Let us know if there are tanks or pipes in the loft
- Note the weather when the leak shows
- Protect furniture and flooring under the leak
- Stay off ladders and the roof
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.
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.
What we look for on each type of roof
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. A low or cracked upstand is a common way in.
Parapet and box gutters
A butterfly roof drains to a central valley gutter. Problems there often show in the rooms on the top floor.
Leaks and storm damage in North Finchley
Heath Hall, about 2.9 miles south, is one of the historic houses in the wider area around North Finchley. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in.
Take an older house close to St. Barnabas Church: water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you let a flat or house near New Southgate station, a clear finding on where water gets in helps you brief a roofer right away. If you look after a building such as Sacks Morasha Jewish Primary School, tracing a leak on a big roof starts with where the water appears and works back.

DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
What we do, step by step
Once we have finished looking, we write up our findings in a report with photos. On timing, it typically takes about one to two hours for most houses, with bigger or more complicated roofs taking longer. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- 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 ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Keep pets in another room
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
