Roof leak investigations in Botany Bay and the rest of Greater London. Surveys run seven days a week.
- Leaks below a flat extension roof
- Water dripping from rafters or underlay
- Leaks at a dormer or roof window
How a roof leak investigation works in Botany Bay
Some ‘leaks’ aren’t leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. We check the pattern of damp, the weather and the ventilation before reaching a view. We survey slate and tile slopes, lead flashings and flat roof details, and the problems we are asked to look at most are water coming in around a roof light or dormer and damp patches next to the stack.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Botany Bay, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
Where we can’t see part of the leaking roof, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Useful tips for Botany Bay property owners
Nothing here needs a ladder. A few suggestions:
- Have an electrician check any wet fittings
- Move stored items away from the hatch
- Put a bucket under the drip and move valuables
- Let us know if there are tanks or pipes in the loft
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Don’t 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.
DIY checks: what’s safe
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where applicable.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Why it is worth a survey now in Botany Bay
A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it and have an electrician check it. Then the source needs tracing. Any roof job in Botany Bay means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400. We confirm the price for the job before you book.

The survey, step by step
The visit usually starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. All told, expect between one and two hours for most houses; commercial roofs usually need 3–4 hours. In a London area like Botany Bay, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- You pick a Basic, Standard or Premium Survey.
- 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 the survey
- Point out any leaks or damp patches
- Have any paperwork from past roof work to hand
- Check the loft hatch can be reached
Book a survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, call 07833 053749 or drop us an email.

Botany Bay: your questions answered
Does a conservation area affect roof work in Botany Bay?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Botany Bay?
We do. The survey and report are the same in Botany Bay as anywhere else, and visits run on weekdays and weekends.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it’s useful, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
What happens next?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you always find the source?
We cannot promise to find every leak on one visit. Many leave clear signs, but intermittent leaks that need particular weather can be harder. The report sets out what we found and the most likely routes.
Leaks and storm damage in Botany Bay
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in 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. The wider area around Botany Bay has a long history of building, with Forty Hall about 2.5 miles east. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
For businesses in and around places like Spires Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. Living close to Trent Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn. Landlords with a home close to Crews Hill station may find that a tenant living with a leak needs the cause found, not just the stain painted over.

Landlord and commercial surveys in Botany Bay
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the survey around it.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
What we look for on each type of roof
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
Lead flashings
A leak at a flashing often shows some way from the joint. That is why we check the flashings near a stain, not just the one directly above.
