About our roof leak investigation in Slade Green
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot, along with any photos you’ve taken. Even on a dry day, a leak normally leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. We survey valleys and parapet gutters, flat roof details and rooflights and dormers, and common reasons people get in touch are leaks below a flat extension roof and damp walls below an overflowing gutter.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Slade Green, 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: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Tell us if there are tanks or pipes in the loft
- Take dated photos of the leak
- Let us know about any past repairs to the roof
- Do not touch fittings that water is reaching
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that isn’t clear.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.

What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Surveys in Slade Green can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before we arrive

How the survey changes by roof type
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. If that gutter or its outlet fails, water can come through the top-floor ceiling.
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Slade Green roofs and the weather
The wider area around Slade Green has a long history of building, with Hall Place and Gardens about 2.1 miles south-west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of 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.
If you own a rental within reach of Slade Green station, a tenant living with a leak needs the cause found, not just the stain painted over. Trees in and around Braeburn Park shed leaves that can end up in nearby gutters, and blocked gutters overflow and soak walls. For site and facilities teams at buildings such as St. Paul's (Slade Green) Church of England Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

FAQs for Slade Green
Does a conservation area affect roof work in Slade Green?
We can’t 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.
Is parking a problem for a survey in Slade Green?
Parking in Slade Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How do you tell a leak from condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern of damp and the ventilation, then say which is most likely.
How long does the visit take?
The visit usually takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. We’ll confirm what to expect when we arrange the visit.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Do you need to get into the loft?
Typically, if there’s one and it can be reached safely. The loft space can show things the outside cannot, such as damp timbers, staining or daylight.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. Points are put in order of urgency where relevant.
Why it’s worth a survey now in Slade Green
Patching the spot above the stain often doesn’t work. 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.
