About our roof leak investigation in Crooked Billet
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. Each one is checked from wherever it is safe to see it. If you’re worried about staining around the chimney inside and leaks below a flat extension roof, a survey will tell you what’s going on.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you are tracing a leak or recording storm damage in Crooked Billet, 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.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What happens on the day
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof cannot be seen, the report says so. Most visits take about 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. From the street, a London terrace normally shows only its front slope or parapet, so a visit in Crooked Billet moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.

Roof leak investigations in Crooked Billet: local notes
With Southside House about 0.5 miles south-west, Crooked Billet sits in an area with a long building history. 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. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Each of these roof types has its own typical places for water to get in.
For an older house near a landmark like Christ Church, water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you let a flat or house near Raynes Park station, tracing a leak quickly matters when a tenant is living with it. If you live near a park like Cannizaro Park, or anywhere with mature trees, autumn leaves can block gutters and valleys.

Why act early in Crooked Billet
A leak near lights or wiring needs attention quickly. Keep away from any fitting that water is reaching. Then the source needs tracing. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is often older than it looks.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. The price for your roof depends on its size, access and what you need to know.

Roof by roof
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.
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. We check outlets and the covering around them.
Useful tips for Crooked Billet property owners
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Have an electrician check any wet fittings
- Write down the wind direction and rain when it leaks
- Keep a photo record of the damp patch
- Tell us if there are tanks or pipes in the loft
If the leak turns out to be condensation, the report says so, and suggest how the loft space could be better ventilated. It saves chasing a leak that isn’t there.
Do not block the vents at the eaves. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation does not block airflow at the eaves.
FAQs for Crooked Billet
Does a conservation area affect roof work in Crooked Billet?
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 Crooked Billet?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
How much does a roof leak investigation cost in Crooked Billet?
Prices start from £150, including VAT. We confirm the exact price before you book. To get a price, ring 07833 053749 or drop us an email.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
How long does a roof leak investigation take?
Allow about 1–2 hours for most homes, though a hard-to-trace leak can take longer. We’ll give you an idea of timing when booking.
What’s in the survey report?
You get our findings in writing, part by part, with photos. Points are put by urgency where it matters.
Could my leak actually be 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.
