Roof leak investigation in West Marden: what you get
Some ‘leaks’ aren’t leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Knowing which it is means the right fix can be done, since the cure for one won’t solve the other. The pattern of the damp, the ventilation and the timing all help us decide. Common reasons to book are ceiling stains that grow after rain and leaks below a flat extension roof, across rooflights and dormers, chimney stacks and lead flashings.
Being in a small place like West Marden makes no difference to how a leak or storm damage is looked at: the journey and access are just planned ahead of time. Let us know where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photos of the water coming in, they help as well.
After the visit, you get a report with photographs, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Landlords, agents and block managers in West Marden
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
What this survey can’t tell you
Before you book, it is worth knowing what a survey will not do:
- Whether rotten timbers meet design loads
- An intermittent leak that shows no trace on the day
- Defects hidden under coverings or inside walls without opening up
If you are not sure which survey you need, call 07833 053749 or email us and we will give you a straight answer. What a survey covers and doesn’t.
What this survey covers
- Slate and tile slopes
- Flat roof details
- Lead flashings
- The roof space
- Valleys and parapet gutters
- Rooflights and dormers
- Chimney stacks
Leave it or get it looked at?
A leak rarely stays small. Wet timbers start to decay, plaster softens and insulation stops working. Tracing it now means less to put right later. Where a roof is exposed, as many are in small places like West Marden, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 inc. VAT. We’ll tell you which package suits the questions you have.
What you get with us
- 5,000+ surveys completed
- Surveys seven days a week
- Customer satisfaction of 98%
- CAA-registered drone operator (Flyer ID and Operator ID)

Your questions about roof leak investigations in West Marden
Does a conservation area affect roof work in West Marden?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover West Marden?
Yes, West Marden is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Can you inspect my roof with a drone?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
How long does the visit take?
On site, it typically takes between one and two hours, more where the leak is intermittent or the roof is large. Report times depend on the package.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it is part of the Premium Survey. It shows temperature differences, not water itself, so anything it suggests is checked with moisture readings.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
What we look for on each type of roof
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
Valleys
Stains from a valley leak often show some distance off. We trace the route from the loft where there is safe access.
Common roof problems in West Marden
Chimneys can let water in by several routes. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. The damp may appear on a chimney breast, a ceiling or in the loft.
These are some of the problems a survey can pick up:
- Drips from nail tips in a cold loft
- Drips in the loft during heavy rain
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
Take a building like Compton and Up Marden CofE Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Before you book any roof surveyor
- How soon the report will arrive
- Will the report include photos?
- What they will not be able to tell you
- Whether any drone flown is registered with the CAA

Leaks and storm damage in West Marden
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings. Knowing the roof type helps narrow down where water may be getting in. Historic houses such as Uppark, about 2.6 miles north, show how far back building in the area around West Marden goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Rowlands Castle station, a tenant living with a leak needs the cause found, not just the stain painted over. For an older house near a landmark like The Parish Church of St Mary, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

The survey, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. Most surveys take between one and two hours for most homes, though a hard-to-trace leak can take longer. In a small place like West Marden, access is normally 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.
- You tell us where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Outside, we look at every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- For flats, check roof access has been agreed
- Have keys ready for side gates, garages or roof access doors
- Keep pets in another room
