Roof leak investigations for homes and businesses in Totteridge
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. The investigation finds and explains the cause, while the repair is a separate matter. Common reasons to book are staining where a gutter or parapet meets the wall and water dripping from rafters or underlay, across valleys and parapet gutters, flat roof details and chimney stacks.
London’s Victorian and Edwardian roofs have often been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Insurers usually exclude wear and tear, so it helps to know whether damage is old or new. A careful look in Totteridge tells the two apart where the evidence allows. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Stay off ladders and the roof
- Protect furniture and flooring under the leak
- Check whether pipes or tanks run near the stain
- Move stored items away from the hatch
Once the work is done, hold on to the report. If water appears again, it shows what was found before.
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.
Questions from Totteridge
Is parking a problem for a survey in Totteridge?
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.
How do I find out if my home in Totteridge is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Can you always find the source?
We cannot promise it. Water can travel a long way, and some leaks only show in particular storms. Where the source isn’t certain, we list the likely routes in order.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime. Just say which days work for you.
Why doesn’t the damp patch line up with the hole?
Rain that gets in will run along whatever it lands on. On a pitched roof it often runs down a rafter before it shows. Tracing that path is the heart of a leak investigation.
Does the report include photographs?
Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.

What else we do in Totteridge
What affects the cost of roof leak investigations
We confirm the price for the job before booking. This is what makes a difference:
- The roof’s overall size
- Building height and the viewpoints available
- How many separate roofs there are, such as extensions, dormers and garages
- Whether it is a home or a commercial building
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.
What we need to know
Before you get in touch, it helps to have:
- Any deadline, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
- Any marks or damp showing indoors
To get a price for roof leak investigations in Totteridge, phone 07833 053749 or email us. The address, the type of property and what you’d like to know help us give you an accurate price.
Common roof problems in Totteridge
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. Leaks often start at the edges, upstands and outlets.
It is worth booking a survey if you’ve seen:
- Damp underlay across a wide area
- Drips in the loft during heavy rain
- Wet patches high on an inside wall
- Leaks below a flat extension roof
If you look after a building such as The Totteridge Academy, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Questions to ask before you book
- Which viewpoints they use to see the roof
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What follow-up you get after the report
- What experience they bring
How the survey works
Photographs 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. A typical visit takes about 1–2 hours on an ordinary house, or half a day or so for a commercial building. London terraces rarely offer a view of the whole roof from one spot, so a visit in Totteridge moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- You let us know where the water appears, when, and what the weather was doing.
- 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.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Show us where any leaks or stains appear
- Find any records of previous roof work
Booking a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
Advice
What a roof leak investigation doesn’t cover
It is a careful look at the leaking roof, not the whole story. The main limits are:
- Leaks that only appear in weather we can’t recreate
- Leaks from plumbing, tanks or pipework rather than the roof
- Defects hidden under coverings or inside walls without opening up
Not sure which survey suits your roof? You can ring 07833 053749 or email us and we’ll tell you before booking. What a survey covers and does not.

Roof leak investigations around Totteridge
The wider area around Totteridge has a long history of building, with Wyllyotts Manor about 4.2 miles north. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often 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. Knowing the roof type helps narrow down where water may be getting in.
For landlords with property near Oakleigh Park station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you look after a shop, office or commercial unit, for example near Spires Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

Different roofs, different checks
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped.
Chimney stacks
A stack has several possible ways in for rain. Each is checked from every safe viewpoint.
