Roof leak investigation in Key's Green, Kent

When to book a survey in Key's Green
Condensation is often mistaken for a leak. Warm, moist air from the house rises into a cold roof space and condenses, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
Common reasons to book include:
- Water that shows only in certain storms
- Stains around a skylight
- Drips in the loft during heavy rain
- Damp ceilings under a flat roof
If you live near a park like Brenchley Wood, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.

About our roof leak investigation in Key's Green
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt frequently lasts around 15 to 20 years, so age is part of the picture. We’re often asked to look into stains around a skylight and water dripping from rafters or underlay, across rooflights and dormers, chimney stacks and the roof space.
Many homes in small places like Key's Green face open ground, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, 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 a roof leak investigation looks like in Key's Green
Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. You will also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. The covering and its details give the first clues when tracing where water is coming from. With Scotney Castle about 3.6 miles south-east, Key's Green sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
Take an older house close to Chapel Of Ease Of St Luke: water on an older roof tends to find its way in at the lead, the valleys or the chimney. For landlords with property near Frant station, a clear finding on where water gets in helps you brief a roofer straight away.

Key's Green: your questions answered
Do you carry out roof surveys in Key's Green?
Yes, Key's Green is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or drop us an email with the address and some details.
Is Key's Green within the area you cover?
Yes. Key's Green is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What’s in the report?
A report with photographs, explaining the condition of the leaking roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
How long will you be at the property?
On site, it typically takes about one to two hours at most homes, while a commercial roof takes nearer three to four hours. Report times depend on the package.
Could my leak actually be condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We look at the pattern, take moisture readings and tell you which is more likely.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years.
Roof by roof
Chimney stacks
Damp on a chimney breast inside frequently starts at the top of the stack. Unused flues with open pots can let rain straight in.
Lead flashings
Some roofs have mortar where you’d expect lead. They crack as the roof and wall move, letting rain run behind the joint.
What happens on the day
The visit has one job: to look at the leaking roof as closely as is safe and record what we find. Notes and photos go into the written report. The visit normally takes about 1–2 hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Key's Green 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 start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there is safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Check we can get to the back of the property
- Point out any leaks or damp patches
- Make sure pets are kept safely away
Getting a price
To arrange a survey, phone 07833 053749 or drop us an email and let us know the address and what’s prompted the survey. You’ll know the price before anything is booked.
Related advice
What happens if roof problems are left?
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it’s harder to clear. Stopping the water is the first step. Where a roof is exposed, as many are in small places like Key's Green, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.

What affects the cost of roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:
- House, block, shop or office
- The size of the roof
- Height and safe access
- Features like valleys, chimneys, dormers and parapets
Prices start from £150, including VAT. What you pay depends on how big and how high the roof is, access and which survey you book.
What we need to know
A little information up front helps. Please include:
- Any photos you have, taken from the ground or a window
- The type of building and roof, such as pitched or flat
- Your timetable, such as an exchange date
- Any stains, drips or damp patches you’ve seen indoors
If you have photos of the roof, send them over. Take them safely from the ground or a window. To send them or to book, phone 07833 053749 or email us.
Honest limits
Without opening up the roof, some things stay hidden, and that sets some limits:
- Plumbing leaks that look like roof leaks
- Structural calculations (that’s a structural engineer’s job)
- What’s under the covering or behind the plaster
