Roof leak investigations for homes and businesses in South Oxhey
Our roof leak investigations cover South Oxhey and the wider South East. We visit seven days a week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. You get a report with photos and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, and then ring 07833 053749 or email us to arrange a visit. If you’ve noticed damp on a chimney breast and damp underlay across a wide area, 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 South Oxhey, 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.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Different roofs, different checks
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.
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely, and look for signs of past overflowing.
Landlord and commercial surveys in South Oxhey
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we will plan the survey around it.
Freeholders and residents’ companies use a roof report to plan and budget.

Common questions in South Oxhey
Is parking a problem for a survey in South Oxhey?
It depends on the street. If South Oxhey has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in South Oxhey is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you climb onto every roof?
Only if it is safe. We inspect what can safely be seen: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Is it a leak or condensation?
It is a common question. Leaks tend to follow wet weather and show in one place, while condensation is frequently spread out and worse in cold weather. We tell you which it is most likely to be.
How much is a survey?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We can only inspect what we are given access to.
How should I prepare for the leak investigation?
Keep a note of when it leaks. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
What you can safely check yourself
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.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking, as it helps us focus the survey.
What this survey can’t tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Carrying out the fix
- Plumbing leaks that look like roof leaks
- Faults hidden behind ceilings or boarding
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we will tell you before booking. What a survey covers and doesn’t.
Roof types and parts we check

South Oxhey roofs and the weather
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Knowing the roof type helps narrow down where water may be getting in. Historic houses such as Headstone Manor, about 2.4 miles south-east, show how far back building in the area around South Oxhey goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you live near a park like Oxhey Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls. If you live in an older home near Oxhey Chapel, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you look after a shop, office or commercial unit, for instance near Harlequin Centre, finding where water is getting in quickly keeps disruption down.

What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours, more where the leak is intermittent or the roof is large. London terraces rarely offer a view of the whole roof from one spot, so a visit in South Oxhey moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.

Useful tips for South Oxhey property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Leave roof access to professionals
- Keep a photo record of the damp patch
- Let us know if there are tanks or pipes in the loft
- Write down the wind direction and rain when it leaks
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Do not block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Make sure insulation doesn’t block airflow at the eaves.
