How a roof leak investigation works in Southgate
We investigate roof leaks in Southgate and across London and South East England. We visit on weekdays, Saturdays and Sundays. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, and then call 07833 053749 or drop us an email to arrange a visit. We survey rooflights and dormers, slate and tile slopes and valleys and parapet gutters, and the problems we are asked to look at most are damp on a chimney breast and staining where a gutter or parapet meets the wall.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. In Southgate, we inspect what we can reach safely and are given access to. Tell us when the water shows, and in what kind of weather.
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.

Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
Common roof problems in Southgate
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, frequently well away from where it shows.
These are some of the problems a survey can pick up:
- Ceiling stains that grow after rain
- Staining where a gutter or parapet meets the wall
- Water through the ceiling under a flat roof
- Water dripping from rafters or underlay
Homes near green spaces such as Grovelands Park can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls.
Questions to ask before booking
- What the survey won’t cover
- Whether you get a written report with photos
- What insurance they carry
- Is VAT included in the price?
What this survey cannot tell you
Some things cannot be seen without opening up the roof, so a survey has limits:
- Whether rotten timbers meet design loads
- Carrying out the fix
- A promise to find every leak on a single visit
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we’ll tell you before you book. What our survey covers.

How it works
The aim of the visit is simple: to see as much of the leaking roof as can safely be seen and record it clearly. Notes and photographs go into the written report. The visit typically takes an hour or two for most homes, though a hard-to-trace leak can take longer. In Southgate, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Before we arrive
- Mention any parking restrictions on your street
- Move anything stored under the loft hatch
- If you are buying, let the agent know when we’re coming
Arrange a survey
A quick phone call is normally the easiest start: call 07833 053749 or send us an email, and we’ll ask about the building and what you need. You will have a price before anything is arranged.
Advice
Leaks and storm damage in Southgate
The wider area around Southgate has a long history of building, with Bruce Castle about 3.2 miles south-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Southgate is one of them, bay roofs, hips and later dormers each have their own details. Knowing the roof type helps narrow down where water may be getting in.
Take an older house close to Christ Church Southgate Parish Church: lead flashings, valleys and old chimneys are typical places for water to get in. Anyone responsible for a site like Ashmole Primary School will know that a leak through a large roof is frequently found some distance from where the water shows inside.

Roof by roof
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely, and look for signs of past overflowing.
Valleys
Leaves and moss build up in valleys and hold water back. In heavy rain, it can spill under the edges of the slates or tiles.
Southgate questions
Is my home in Southgate listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Can parking be tricky for a visit in Southgate?
Sometimes, yes. If Southgate has controlled parking where you are, a visitor permit is the easiest answer.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
How should I prepare for the leak investigation?
Check the loft can be reached. Gather any photos and notes about when it leaks, and tell us about past repairs. Keep catching drips and keep water away from electrics.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it when booking and we will explain what’s needed.
Which days do you carry out surveys?
Surveys run on weekdays, Saturdays and Sundays. To arrange a date, call 07833 053749 or drop us an email.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
What a survey costs
To price your survey, we look at:
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
- How complicated the roof is, with its valleys, chimneys and parapets
- Basic, Standard or Premium
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Getting in touch
We will typically ask about:
- The address and postcode of the property
- Where any leaks, stains or damp patches show inside
- What made you get in touch
- The kind of building and roof involved
To arrange a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. We will confirm the price before booking.
