Why it is worth a survey now in Southfields
Damp loft insulation loses much of its value. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
All our prices include VAT. Prices start from £150, including VAT. We confirm the price for your roof before booking.

Roof leak investigation in Southfields: what you get
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that don’t drain. 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. If you’ve noticed a leak that comes and goes with the weather and leaks at a dormer or roof window, we can find out what’s behind it, whatever the roof.
Water getting into a London home frequently comes from a detail you can’t see from the street: 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 Southfields, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

What you can safely check yourself
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.

Signs you need a roof leak investigation in Southfields
Every flat roof covering has a working life. A felt roof frequently lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Upstands and outlets are common weak points.
People typically book a survey after spotting something like this:
- Water marks that spread in wet weather
- A leak that comes and goes with the weather
- Damp on a chimney breast
- Damp walls below an overflowing gutter
For an older house near a landmark such as St John the Divine, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Before you book any roof surveyor
- Their report turnaround times
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- Whether the roof space is looked at, where there is one
Questions from Southfields
Is my home in Southfields listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is parking a problem for a survey in Southfields?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Is the repair included in the leak investigation?
Our job here is to trace the leak and explain it, and the repair is separate. The report gives any roofer a clear brief.
Do you need to get into the loft?
If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
Can every leak be traced?
Not always, and we’ll be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we can’t be sure, the report ranks the possible sources.
Is Southfields in your area?
Yes. We survey roofs in Southfields and the rest of Greater London, as part of our work across London and South East England. For a price, ring 07833 053749 or use the contact form.
Is there anything I need to do ahead of the visit?
Clear the loft hatch so we can get into the loft space. Gather any photos and notes about when it leaks, and let us know about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Roof by roof
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
Valleys
Stains from a valley leak often show some distance off. We trace the route from the loft where there is safe access.
How it works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. Most visits take an hour or two on an ordinary house, though large, tall or awkward roofs take more time. In Southfields, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You tell us 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.
Before the survey
- Make sure we can get to the back of the property
- Clear the way to the loft hatch
- Keep pets out of the way during the survey
Booking a survey
Getting a price is simple: just ring 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

Leaks and storm damage in Southfields
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Knowing the roof type helps narrow down where water may be getting in. Historic houses such as Fulham Palace, about 1.9 miles north-west, show how far back building in the area around Southfields goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near Earlsfield station, a clear finding on where water gets in helps you brief a roofer right away. Homes near green spaces like King George's Park can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching.

Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Mention any plumbing above the damp area
- Put a bucket under the drip and move valuables
- Keep water away from lights and sockets
- Write down the wind direction and rain when it leaks
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. You can ask us about anything that isn’t clear.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
