Roof leak investigation in Crossbush
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. Each one is looked at from wherever it is safe to see it. We are often asked to look into staining where a gutter or parapet meets the wall and leaks below a flat extension roof, across slate and tile slopes, rooflights and dormers and lead flashings.
For a small place like Crossbush, the inspection is the same as anywhere: the journey and access are just planned beforehand. Tell us where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. Photos of the stain and of the roof from outside are helpful too.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, with the urgent items made clear.

Why get it checked now?
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. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
To find out what your survey will cost, call 07833 053749 or use the contact form and let us know about the roof. We’ll confirm the figure before booking.

Your questions about roof leak investigations in Crossbush
Does a conservation area affect roof work in Crossbush?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover smaller places like Crossbush?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Just mention lanes, gates or anything else about the route as you book.
What’s in the survey report?
You get our findings in writing, part by part, with photos. Points are put by urgency where it matters.
Why doesn’t the damp patch line up with the hole?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
Can you inspect my roof with a drone?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak normally shows in one area and follows rain, while condensation is often widespread and worst on cold days. The report explains which it looks like and what to do.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
What we cannot see
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Leaks from plumbing, tanks or pipework rather than the roof
- A structural engineer’s report
- Carrying out the fix
If in doubt, call 07833 053749 or send us an email and we will suggest the right survey before booking. What our survey covers.

Roof leak investigations around Crossbush
Crossbush is within about 3 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Driving rain off the sea can be pushed into gaps that stay dry in calmer weather, and salt air slowly wears metal fixings. Historic houses such as Ecclesden Manor, about 3 miles east, show how far back building in the area around Crossbush goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Arundel station, a tenant living with a leak needs the cause found, not just the stain painted over. For an older house near a landmark such as The Parish Church of St Mary Magdalen, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

Roof by roof
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, letting rain run behind the joint.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is looked at from every safe viewpoint, and look for damp on the breast inside.
How we price roof leak investigations
When we price a survey, we consider:
- Chimneys, valleys, parapets and other details
- The use of thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- The package you choose: Basic, Standard or Premium
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
Helping us price your survey
When you call or email, these details help:
- What kind of property and roof it is
- Any photos you have, taken from the ground or a window
- The property’s address and postcode
- How the loft is reached, if there is one
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or drop us an email with the details.
How it works
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely, from the ground, from windows, in the loft space and by drone where applicable. Most surveys take an hour or two for most houses, though large, tall or awkward roofs take more time. In a small place like Crossbush, 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. Weekday and weekend visits are available.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Before the survey
- Let us know about parking before the day
- Tell us about any leaks, stains or damp patches you know of
- Unlock side gates and any roof access doors
Arrange a survey
Not sure which survey you need? It’s easiest to ring 07833 053749 or email us and describe the roof and why you want it surveyed. We will explain the options and the price.
Related advice
When to book a survey in Crossbush
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Signs worth acting on include:
- Damp walls below an overflowing gutter
- Stains around a skylight
- Damp underlay across a wide area
- Leaks that appear only in driving rain
For site and facilities teams at buildings such as The Littlehampton Academy, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
