What we look for on each type of roof
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak, particularly in driving rain.
Roof leak investigation in Furzedown
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. We find and report the source, and the repair itself is a separate job. We are often asked to look into staining around the chimney inside and drips in the loft during heavy rain, on chimney stacks, flat roof details and lead flashings.
In London, leaks often 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 Furzedown, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Why it is worth a survey now in Furzedown
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Roof leak investigation starts from £150, including VAT.

Furzedown: your questions answered
Do you cover Furzedown?
Yes, Furzedown is one of the places we work. The survey and report are the same in Furzedown as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Furzedown?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can every leak be traced?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. Where the source is not certain, we list the likely routes in order.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that in advance, but the loft and any rooms with damp need someone to let us in.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
How do you tell a leak from condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Landlord and commercial surveys in Furzedown
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Freeholders and residents’ companies use a roof report to plan and budget.
What happens on the day
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take an hour or two, more where the leak is intermittent or the roof is large. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Furzedown runs like any other.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Buyers: confirm access with the estate agent or seller

Checking the roof from ground level
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Make sure the loft is accessible
- Don’t touch fittings that water is reaching
- Check whether pipes or tanks run near the stain
- Catch drips in a bucket and protect the floor
We email the report to you. It sets out where we believe the water is getting in, how it’s travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
What a roof leak investigation looks like in Furzedown
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Different coverings let water in at different points, which shapes where the search starts. Kingswood House, about 2.9 miles east, is one of the historic houses in the wider area around Furzedown. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
Take a building like Graveney School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you own one of the older houses in the streets near St Paul's Church, the leak may come from a chimney, a valley or tired lead rather than the covering itself. Homes near green spaces such as Figge's Marsh can get more leaves in their gutters in autumn.
