Roof leak investigation in Ashtead: what you get
Our job is to find the likely source and tell you. You get a report with photographs showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. We survey the roof space, rooflights and dormers and flat roof details, and people most often book us about damp ceilings under a flat roof and damp underlay across a wide area.
When a storm passes over a town like Ashtead, loose tiles, slates and ridges are the first to move. What counts as a storm depends on your policy; many use gusts of around 55 mph. A report setting out the damage, with photographs, helps you explain what you’ve found, whether to an insurer or a roofer. Because wear and tear is usually excluded, the age of any damage matters.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

FAQs for Ashtead
How should I get ready for a visit in Ashtead?
Mostly, it’s about access: the loft hatch, any locked gates and where to park in Ashtead. Tell us about known leaks or past repairs as well.
Is my home in Ashtead listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
Can you always find the source?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. Where the source isn’t certain, we list the likely routes in order.
How much does a roof leak investigation cost in Ashtead?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
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. Each one is emailed, ready to forward.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. We’ll recommend an engineer if we see signs that call for one.
What we do, step by step
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes an hour or two for most homes, though a hard-to-trace leak can take longer. A visit in Ashtead runs most smoothly with the loft hatch clear, side gates open and a parking spot in mind. Someone needs to let us in, so tell us who that will be.

Tips that help
Most of what helps is simple and safe from the ground. Our suggestions:
- Keep a photo record of the damp patch
- Catch drips in a bucket and protect the floor
- Mention any plumbing above the damp area
- Make sure the loft is accessible
We email the report to you, with photographs of what we found. It sets out where we believe the water is getting in, how it is travelling and what needs attention. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
Why act early in Ashtead
Wet insulation does not insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Around Ashtead, gutters that overflow soak the wall below. A slipped tile or worn flashing does the same higher up. Neither gets better on its own.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Why us?
- An independent view of the roof
- We hold a CAA Flyer ID and Operator ID

Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Landlords, agents and block managers in Ashtead
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Do you need a roof leak investigation in Ashtead?
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can push water under the slates or tiles. The stain may appear well away from the valley itself.
It’s worth booking a survey if you’ve seen:
- Ceiling stains that grow after rain
- A leak that comes and goes with the weather
- Leaks below a flat extension roof
- Wet patches high on an inside wall
The streets around a church such as St George's Church are frequently among the oldest in a place, and if you own one of the older houses nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Choosing a roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Their track record with similar roofs
- Whether the loft is part of the inspection
- What’s outside the scope of the survey
