Roof leak investigation in Rowhook
Flat roofs leak in their own ways. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. Felt frequently lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed wet patches high on an inside wall and damp underlay across a wide area, we can find out what’s behind it, whatever the roof.
Roofs in small places like Rowhook 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.
The report records the leaking roof as we found it on the day. It is useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

The survey, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours for a house, and longer for a large or complex roof. In a small place like Rowhook, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We look at the stain, the ceiling and the loft above it.
- Outside, we look at 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
- Make sure the loft hatch can be reached
- If you are buying, check with the agent that we can get in
- Point out any leaks or damp patches
Booking a survey
Getting a price is simple: just phone 07833 053749 or drop us an email and give us a few details about the property and we will explain which survey suits. The price is agreed up front.

Rowhook: your questions answered
Does a conservation area affect roof work in Rowhook?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Rowhook?
Yes, Rowhook is covered. We survey roofs across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
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.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps.
What will the report tell me?
It works through the roof part by part, in writing and with photos. Points are put with the most urgent first where relevant.
How much is a survey?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose, and it is agreed before booking.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Why get it checked now?
A leak that returns after a repair normally means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Older and listed buildings around Rowhook may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.

When to book a survey in Rowhook
Flat roofs fail with age and wear. 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.
These are some of the problems a survey can pick up:
- Ceiling stains that grow after rain
- Water that shows only in certain storms
- Damp underlay across a wide area
- Leaks at a dormer or roof window
If you let a flat or house near Warnham station, a tenant living with a leak needs the cause found, not just the stain painted over.
Before you book any roof surveyor
- What experience they bring
- Whether VAT is added on top
- What happens after the report arrives
- Do they have a CAA Flyer ID and Operator ID for drone work?
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Landlord and commercial surveys in Rowhook
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Tell us about it as you book and we’ll plan the visit with that in mind.
Freeholders and residents’ companies use a roof report to plan and budget.
What we look for on each type of roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. Outlets and the area around them are looked at.
Valleys
A valley takes the rain from both sides of the roof. Split lead, cracked linings or slipped tiles let water in.

Roof leak investigations in Rowhook: local notes
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your 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, so check with the council. Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Each of these roof types has its own typical places for water to get in.
If you live near a park such as Farlington Strood Park, or anywhere with mature trees, autumn leaves can block gutters and valleys. If you look after a building such as Farlington School, on a building that size, finding the source of a drip means looking well beyond the stain.
