Rock Roof Leak Investigation

Roof leak investigation in Rock: what you get
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, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. We survey the roof space, chimney stacks and flat roof details, and people most frequently book us about staining around the chimney inside and stains around a skylight.
Being in a small place like Rock makes no difference to how a leak or storm damage is looked at: the journey and access are just planned beforehand. It helps to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Wind, rain and roofs in Rock
Many older homes in Sussex have handmade clay tiles and tile-hung walls. Some old buildings in Sussex have Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from. Parham House, about 3.9 miles west, is one of the historic houses in the wider area around Rock. 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.
Anyone responsible for a site like St Mary's CofE Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. If you live in an older home near The Parish Church of St Mary, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Rock is about 6 miles north of Worthing, in West Sussex. Houses, flats, blocks and commercial buildings in Rock can all book roof leak investigations. Rock is one of the towns and villages in West Sussex where we work for roof leak investigations. For surveys nearby, see our Brighton page.
Surveys in RH20 work the same way as everywhere else we cover. We offer roof leak investigations to properties on Old London Road, London Road and Lamorna Close. We also cover the places around Rock: Washington (1 mile south), Heath Common (1 mile north-west), Sullington (1 mile west), Warminghurst (2 miles north) and Storrington (2 miles west). We also work in nearby towns such as Horsham (11 miles north), Worthing (6 miles south), Bognor Regis (15 miles south-west), Haywards Heath (15 miles north-east), Burgess Hill (12 miles east) and Littlehampton (9 miles south-west).
What’s near Rock
In Rock, that means homes and buildings near Rydon Community College and The Frankland Arms Public House. A little further out are The Storrington And District Museum (1.9 miles west). Not far away are Chanctonbury Hill.
Why act early in Rock
A leak near lights or wiring needs attention quickly. Keep away from any fitting that water is reaching. Then the source needs tracing. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, which starts from £400, with VAT included. We’ll tell you which package suits the questions you have.
Why book with us

What a roof leak investigation doesn’t cover
Some things cannot be seen without opening up the roof, so a survey has limits:
- What’s under the covering or behind the plaster
- Whether rotten timbers meet design loads
- An intermittent leak that shows no trace on the day

Your questions about roof leak investigations in Rock
Will you come out to Rock?
Yes, Rock is covered. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Do you cover Rock?
Yes, Rock is within the area we cover. We work right across London and the South East. You can phone 07833 053749 or drop us an email with the address and a few details.
What does a roof survey cost?
Our price is from £150, including VAT. We confirm the price for your survey before booking. For a price, phone 07833 053749 or use the contact form.
Why doesn’t the damp patch line up with the hole?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is often well away from the mark. We follow the route back instead of guessing.
How do I book a survey in Rock?
Just phone 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
Are you insured?

Landlords, agents and block managers in Rock
Letting agents can arrange access with tenants. We survey seven days a week, which can make access easier.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant beforehand.
What happens on the day
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit usually takes roughly 1–2 hours at most homes; commercial roofs usually need 3–4 hours. Cottages and farmhouses around Rock frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Make sure pets are kept safely away
- Clear the way to the loft hatch
- Jot down any questions you want answered
How to book
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or email us to find out.
Advice
Different roofs, different checks
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely, and look for signs of past overflowing.
DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
