How a roof leak investigation works in Ash
Most roof leaks start at a joint rather than the middle of a slope. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. Each one is looked at from wherever it is safe to see it. Common reasons to book are water coming in around a roof light or dormer and leaks below a flat extension roof, across the roof space, slate and tile slopes and rooflights and dormers.
Many homes in small places like Ash face open ground, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

What happens on the day
There isn’t much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes about 1–2 hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Ash can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Getting ready for the survey
- Agree roof access with the managing agent if it’s shared
- Jot down any questions you want answered
- If you are buying, let the agent know when we’re coming

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
What a roof leak investigation looks like in Ash
About 4.2 miles west lies Lullingstone Castle, a reminder of how long the area around Ash has been built on. Older homes in the wider area often have features worth a closer look, like 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. Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Knowing the roof type helps narrow down where water may be getting in.
Take an older house close to Parish Church of Saint Peter and Saint Paul: leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks. Anyone responsible for a site like New Ash Green Primary School will know that tracing a leak on a big roof starts with where the water appears and works back.
Ash is about 6 miles south-west of Northfleet, in Kent. From houses to flats and shops in Ash, the roof can be surveyed on a weekday or at the weekend. We cover towns and villages across Kent, large and small. You can also see our page for Maidstone.
Postcode districts we cover here for roof leak investigations: TN15 and DA3. Whether your property is on Ash Road, The Street and Billet Hill or anywhere close by, we can survey it. If you’re just outside Ash, we cover West Yoke (1 mile north), Fawkham Green (1 mile north-west), Speed Gate (1 mile north-west), Stansted (2 miles south) and West Kingsdown (2 miles south-west).

Near you in Ash
Typical jobs here are in homes near The White Swan Public House, among other places. For rail, the closest station is Longfield station, about 2.8 miles north of the centre. Nearby you’ll also find Darent Valley Hospital (5.6 miles north) and Eynsford Castle (3.6 miles west).
Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- Put a bucket under the drip and move valuables
- Clear the loft hatch so we can get in
- Don’t touch fittings that water is reaching
- Note the weather when the leak shows
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. You can ask us about anything that is not clear.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
What happens if roof problems are left?
Wet insulation does not insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Matching old materials, like handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Every price we give includes VAT, and the report isn’t charged as an extra. Roof leak investigation starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

What we are asked to look at in Ash
Every flat roof covering has a working life. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
Most people get in touch after spotting one of these:
- Damp ceilings under a flat roof
- Staining around the chimney inside
- Staining where a gutter or parapet meets the wall
- Wet patches on loft insulation
If you own a rental within reach of Longfield station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
What to check before booking
- How long they’ve been surveying roofs
- Whether you get a written report with photos
- Whether the loft space is looked at, where there is one
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Ash: your questions answered
Do you cover Ash?
Yes. We work right across London and South East England, and Ash is part of that. Just ring 07833 053749 or email us and tell us about the property.
Is my home in Ash listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s 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.
Does the report include photos?
Yes, every report has them. Pictures sit next to the findings they show.
Is it a leak or condensation?
It is a common question. A leak usually shows in one area and follows rain, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Is this an asbestos survey?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Can you find a leak when it is not raining?
In most cases, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we’ll tell you what we found and what’s most likely.
