Leaks and storm damage in Cowden
Bassetts Manor, about 1.7 miles south, is one of the historic houses in the wider area around Cowden. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If yours is one of the older homes in the streets near Church of St Mary Magdalene, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Cowden is about 5 miles east of East Grinstead, in Kent. We carry out roof leak investigations in Cowden for houses, flats, blocks and commercial buildings, with a written report and photographs every time. Across Kent, we cover Cowden and the places around it. There is also a page for Crawley.

About our roof leak investigation in Cowden
On older houses, leaks frequently start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof frequently turns out to be the source in heavy rain. We check parapets, valleys and flashings from every safe viewpoint. Our report shows what we found, with photos. We are often asked to look into water that shows only in certain storms and water marks that spread in wet weather, on valleys and parapet gutters, slate and tile slopes and lead flashings.
Roofs in small places like Cowden often stand in the open, where storms hit ridges, verges and chimneys hardest. 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.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your questions about roof leak investigations in Cowden
Will you come out to Cowden?
We do. Villages and rural addresses get the same survey as a town house.
Do you cover Cowden?
Yes. We work right across London and the South East, and Cowden is part of that. Just ring 07833 053749 or email us and let us know about the property.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
Do you take photos of the roof?
Yes. Photos are part of every report.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
Is this an asbestos survey?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What happens on the day
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. You’re welcome to ask questions while we’re there. Cottages and farmhouses around Cowden often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- Outside, we check every likely route in.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- If you’re buying, let the agent know when we’re coming
- Keep pets out of the way during the survey
- If the roof is shared, arrange access with whoever manages the building
How to book
If you’re buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.

What we look for on each type of roof
Valleys
Valleys collect water from two roof slopes. Split lead, cracked linings or slipped tiles let water in.
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. A low or cracked upstand is a common way in.
What a survey costs
Survey packages start from £150, inc. VAT. The price for your roof depends on:
- Commercial roofs and larger buildings
- Height and safe access
- Which survey package you book
- Extensions, dormers and garages with roofs of their own
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, including VAT. We can help you choose the package that fits what you want to find out.
Booking your survey
Before you get in touch, it’s useful to have:
- Your timetable, such as an exchange date
- The kind of building and roof involved
- Whether there’s a loft hatch, a shared roof or tricky access
- Photos of the roof, taken safely from ground level or a window
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or send us an email.
Signs you need a roof leak investigation in Cowden
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
Common reasons to book include:
- Leaks below a flat extension roof
- Staining around the chimney inside
- Damp underlay across a wide area
- Staining where a gutter or parapet meets the wall
If you own a rental within reach of Cowden station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
Before booking any roof surveyor
- What exactly goes into their report
- Which limits apply to the survey
- Whether the loft is part of the inspection
- What follow-up you get after the report
Why act early in Cowden
Water and electrics do not mix. If water is reaching a light fitting or switch, keep clear of it and have an electrician check it. Then the source needs tracing. In a small place like Cowden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Prices quoted always include VAT, and the report is not charged as an extra. Roof leak investigation starts from £150, including VAT. Size, height and access decide where your roof falls.
