Marehill Roof Leak Investigation
Independent roof leak investigations in Marehill. We have completed more than 5,000 surveys across London and the South East.
- Water marks that spread in wet weather
- Water through the ceiling under a flat roof
- Staining where a gutter or parapet meets the wall
What we do, step by step
The visit typically starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Older rural homes like those around Marehill can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Preparing for the visit
- Leave side gates unlocked
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller

About our roof leak investigation in Marehill
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. The investigation finds and explains the cause, while the repair is a separate matter. Typical surveys look at leaks that appear only in driving rain and damp walls below an overflowing gutter, across chimney stacks, the roof space and slate and tile slopes.
Roofs in small places like Marehill frequently stand in the open, 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.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Marehill roofs and the weather
Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. About 1.4 miles west lies Old Place Manor, a reminder of how long the area around Marehill has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you look after a building such as St Mary's Church of England Primary School, on a building that size, finding the source of a drip means looking well beyond the stain. Take an older house close to Wiggonholt Church: water on an older roof tends to find its way in at the lead, the valleys or the chimney. Landlords with a home close to Pulborough station may find that tracing a leak quickly matters when a tenant is living with it.
Marehill is about 10 miles north of Worthing, in West Sussex. We carry out roof leak investigations in Marehill for houses, flats, blocks and commercial buildings, with a written report and photographs every time. Across West Sussex, we cover Marehill. Brighton is in our area too.

Can I check my roof myself?
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Marehill: your questions answered
Does a conservation area affect roof work in Marehill?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Is Marehill in the area you cover?
Yes, Marehill is one of the places we work. The survey and report are the same in Marehill as anywhere else.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it’s useful, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
Landlord and commercial surveys in Marehill
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, ring 07833 053749 or email us with the addresses.
Landlords and letting agents in Marehill book surveys as well as householders. A photo-illustrated written report gives you a clear record of the leaking roof, which helps you plan work between tenancies.
Why get it checked now?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. In a small place like Marehill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. Size, height and access can affect the price too.

Take a look at how roof surveys are priced and what we found on two real jobs.
Roof by roof
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, letting rain run behind the joint.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it’s too low, cracked or poorly dressed, water gets behind it.
