Roof leak investigations in South Darenth from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and the South East.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Roof leak investigation in South Darenth
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. We’re often asked to look into drips in the loft during heavy rain and brown rings on upstairs ceilings, across slate and tile slopes, lead flashings and the roof space.
Many homes in small places like South Darenth face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
The report records the leaking roof as we found it on the day. It is useful straight away, and a good reference for later, like when you want to compare after future work.

Signs you need a roof leak investigation in South Darenth
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
We are frequently asked to look at:
- A leak that comes and goes with the weather
- Wet patches high on an inside wall
- Water coming in around a roof light or dormer
- Drips in the loft during heavy rain
Homes near green spaces such as Darenth Country Park can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls.
Before booking anyone
- Are they insured for the work?
- What they will not be able to tell you
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Which parts of the roof they’ll actually see

South Darenth roofs and the weather
Lullingstone Castle, about 3.9 miles south-west, is one of the historic houses in the wider area around South Darenth. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. You will also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Each of these roof types has its own typical places for water to get in.
If you own a rental within reach of Farningham Road station, tracing a leak quickly matters when a tenant is living with it. Take an older house close to The Parish Church of Saint Mary: old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Your questions about roof leak investigations in South Darenth
Is South Darenth within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is South Darenth in the area you cover?
Yes, South Darenth is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Will you definitely find the leak?
Not always, and we’ll be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Which days do you carry out surveys?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Leave it or get it looked at?
A leak that returns after a repair usually means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. That’s frequently what breaks the cycle. Older cottages and farmhouses around South Darenth can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 with VAT included. We’ll tell you which package suits the questions you have.

What we do, step by step
The visit has one job: to look at the leaking roof as closely as is safe and record what we find. Notes and photographs go into the written report. It typically takes between one and two hours, more where the leak is intermittent or the roof is large. Older roofs in small places like South Darenth can have low, tight loft spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it’s useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Getting ready for the survey
- Move anything stored under the loft hatch
- Let us know where we can park nearby
- Have any questions written down, so nothing gets missed
Book a survey
Booking is simple: just ring 07833 053749 or use the contact form, let us know about the property and we will explain which survey suits. The price is agreed up front.

Practical tips
Small things make a difference. Our tips:
- Don’t climb onto the roof to look
- Note the weather when the leak shows
- Catch drips in a bucket and protect the floor
- Keep a photo record of the damp patch
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that is not clear.
Keep the roof space ventilated. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
