Questions from How Green
Do you cover smaller places like How Green?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you carry out roof surveys in How Green?
Yes, How Green is one of the places we work. The survey and report are the same in How Green as anywhere else, and visits run on weekdays and weekends.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
How experienced are you?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
Is it a leak or condensation?
It is a common question. Leaks tend to follow wet weather and show in one place, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Let us know about it when you book and we’ll plan the survey around it.
About our roof leak investigation in How Green
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. The investigation finds and explains the cause, and the repair itself is a separate job. If you’ve noticed water dripping from rafters or underlay and water that shows only in certain storms, we can find out what’s behind it, on flat roof details, rooflights and dormers and valleys and parapet gutters alike.
Many homes in small places like How Green face open ground, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

Why get it checked now?
Water and electrics do not mix. Keep away from any fitting that water is reaching. Finding where the water is getting in should follow right away. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.

Roof leak investigations in How Green: local notes
Historic houses such as Hever Castle, about 0.7 miles south, show how far back building in the area around How Green goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. 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. Each of these roof types has its own typical places for water to get in.
Homes near green spaces such as Chiddingstone Castle Park and Gardens can get more leaves in their gutters in autumn. For landlords with property near Hever station, tracing a leak quickly matters when a tenant is living with it.
How Green is about 7 miles south-west of Sevenoaks, in Kent. From houses to flats and shops in How Green, the roof can be surveyed on a weekday or at the weekend. We cover towns and villages across Kent. For surveys nearby, see our Crawley page.

Landmarks near How Green
Around How Green, our work takes us to homes and buildings near The Wheatsheaf Public House and Chiddingstone Castle Park and Gardens and the streets around them. The nearest railway station is Hever station, about 1.3 miles south-west of the centre. A little further out are Tandridge Priory (5.4 miles north-west) and Hever Castle (0.7 miles south).
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which helps when tenants work during the week.
Businesses and commercial landlords can book us too. Larger roofs take longer.
How it works
The aim of the visit is simple: to see as much of the leaking roof as can safely be seen and record it clearly. Notes and photographs go into the written report. It usually takes roughly 1–2 hours for most houses, and more on a big or complicated roof. Older roofs in small places like How Green can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- You receive a written report with photos showing the likely source and what needs attention.
How to prepare
- Make a note of anything you’d like us to look at
- Keep pets inside or away from the areas we’re looking at
- If you’re buying, check with the agent that we can get in
Arrange a survey
Once you know what you need, call 07833 053749 or email us. From there it is a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.

Before and after the survey
Small things make a difference. Our tips:
- Photograph the stain each time it appears
- Catch drips in a bucket and protect the floor
- Leave roof access to professionals
- Tell us if there are tanks or pipes in the loft
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found, which makes the next step quicker.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Photograph anything new.
Common roof problems in How Green
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Things that often lead to a survey include:
- Water that shows only in certain storms
- Water coming in around a roof light or dormer
- Damp underlay across a wide area
- Drips in the loft during heavy rain
If you own one of the older houses in the streets near Church of St Peter, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
What to check before booking
- How they plan to inspect the roof safely
- Whether VAT is added on top
- Whether the loft is part of the inspection
- Whether they hold professional indemnity and public liability insurance
