About our roof leak investigation in Biggin Hill
We investigate roof leaks in Biggin Hill and across London and South East England. We visit seven days a week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then call 07833 053749 or use the contact form. We survey valleys and parapet gutters, chimney stacks and the roof space, and the problems we are asked to look at most are brown rings on upstairs ceilings and damp ceilings under a flat roof.
London’s Victorian and Edwardian roofs have frequently been repaired many times. Insurers usually exclude wear and tear, so it’s useful to know whether damage is old or new. That is as true in Biggin Hill as anywhere in London. A written record with photos helps you explain what was found to whoever deals with it next.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

What a roof leak investigation looks like in Biggin Hill
Historic houses such as Down House, about 1.7 miles north-east, show how far back building in the area around Biggin Hill goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Each of these roof types has its own typical places for water to get in.
If you look after a building such as Oaklands Primary Academy, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. Parking in Biggin Hill, as in most of London, takes a little planning: let us know about parking bays, permits or a driveway when you book.

Should I look at the roof myself first?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.

FAQs for Biggin Hill
Can parking be tricky for a visit in Biggin Hill?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Is my home in Biggin Hill listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you climb onto every roof?
Only if it is safe. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.
Is Biggin Hill in your area?
Yes. Our area covers London and South East England, Biggin Hill included.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
What’s the best way to book?
The quickest way is to call 07833 053749 or drop us an email. Tell us the address and a little about the roof, and we will take it from there. Surveys run on weekdays, Saturdays and Sundays.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
The survey, step by step
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and make notes for the report. Most visits take about 1–2 hours for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so a visit in Biggin Hill 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.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- Show us where any leaks or stains appear
- For flats, check roof access has been agreed
- Unlock side gates and any roof access doors
Arrange a survey
Booking is simple: just phone 07833 053749 or drop us an email, let us know about the property and we’ll suggest the right survey. The price is agreed up front.
Advice
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Let us know if there are tanks or pipes in the loft
- Do not touch fittings that water is reaching
- Take dated photos of the leak
- Let us know about any past repairs to the roof
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
Roof by roof
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. Even a single gap can let water in.
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
Do you need a roof leak investigation in Biggin Hill?
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
Here are some of the things we see frequently:
- Wet patches high on an inside wall
- Drips in the loft during heavy rain
- Damp underlay across a wide area
- Water through the ceiling under a flat roof
The streets around a church like St Mark's Church are often among the oldest in a place, and if your home is one of the older ones nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
Choosing a roof surveyor
- What they will not be able to tell you
- Are they insured for the work?
- Whether any drone flown is registered with the CAA
- What experience they bring
Prices for roof leak investigations in Biggin Hill
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Whether it is a home or a commercial building
- Building height and the viewpoints available
- Any need for thermal images or a drone flight
- Whether you choose the Basic, Standard or Premium Survey
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 it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.

Here’s what helps us most when you get in touch:
- Why you want a survey: buying, a leak, a storm or new work
- The style of property, from a terrace to a block
- Whether there is a loft hatch, a shared roof or tricky access
