How the survey works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. A typical survey takes between one and two hours for a house, though large, tall or awkward roofs take more time. In a small place like New Ash Green, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Tell us where we can park nearby
- If it isn’t your property yet, arrange access through the agent

Advice
Roof leak investigation in New Ash Green: what you get
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. We check parapets, valleys and flashings from every safe vantage point. The findings are recorded with photos. If you’ve noticed damp patches next to the stack and stains around a skylight, a survey will tell you what’s going on, on lead flashings, slate and tile slopes and the roof space alike.
Roofs in small places like New Ash Green often stand in the open, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A record with photographs is useful if you need to show the damage to anyone else.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Leaks and storm damage in New Ash Green
Cobham College, about 4.3 miles east, is one of the historic houses in the wider area around New Ash Green. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Each of these roof types has its own typical places for water to get in.
The streets around a church such as Parish Church of Saint Peter and Saint Paul are often among the oldest in a place, and if you own one of the older houses nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney. Homes near green spaces such as Rectory Meadow can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. For landlords with property near Longfield station, tracing a leak quickly matters when a tenant is living with it.

What’s near New Ash Green

What happens if roof problems are left?
Patching the spot above the stain often doesn’t work. The real way in may be a metre or more away. We find the probable source before anyone starts work, so the repair is aimed at the right place. Where a roof is exposed, as many are in small places like New Ash Green, driving rain gets into any weakness, and damp in older walls is slow to dry out.
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.

Useful tips for New Ash Green property owners
You don’t need to be a roofer to help. What helps most:
- Protect furniture and flooring under the leak
- Tell us if there are tanks or pipes in the loft
- Photograph the stain each time it appears
- Mention earlier attempts to fix the leak
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
When you need someone else
In fairness, a roof survey has limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- What’s under the covering or behind the plaster
- Whether rotten timbers meet design loads

Your questions about roof leak investigations in New Ash Green
How do I find out if my home in New Ash Green is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is New Ash Green within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How do I book a survey in New Ash Green?
Just call 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect what can safely be seen: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
Why is the stain in a different place from the leak?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
Can a leak be traced on a dry day?
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.
How long does the visit take?
It typically takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.
