About our roof leak investigation in Dorking
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. Each of these is checked in turn 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’s safe to see it. Typical surveys look at stains around a skylight and leaks below a flat extension roof, across the roof space, chimney stacks and slate and tile slopes.
Many homes around Dorking have been extended, frequently with flat roofs or dormers, and the joint between new and old is a classic place for water to get in. Flashings, upstands and the edges of flat roofs are checked alongside the main roof, inside and out. The stain inside is frequently some way from where water gets in, especially around extensions.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that’s said too.

What else we do in Dorking
Dorking: your questions answered
Is Dorking in the area you cover?
Yes, Dorking is within the area we cover. We survey roofs across London and the South East. You can ring 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.
How do I find out if my home in Dorking is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s included in our Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
How much is a survey?
Our price is from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it is agreed before booking.
Do you use drones?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
What’s in the survey report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
Can a leak be traced on a dry day?
In most cases, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
What we are asked to look at in Dorking
Every flat roof covering has a working life. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
Problems we come across frequently include:
- Damp patches next to the stack
- Wet patches on loft insulation
- Water through the ceiling under a flat roof
- Staining where a gutter or parapet meets the wall
Living close to Deepdene Terrace is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What happens after the report arrives
- Whether the price includes VAT
- How long the report takes to arrive
What a roof leak investigation doesn’t cover
Before you book, it’s worth knowing what a survey won’t do:
- A structural engineer’s report
- Leaks that only appear in weather we can’t recreate
- Defects hidden under coverings or inside walls without opening up
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer before booking. What a survey covers and doesn’t.
What this survey covers
- Slate and tile slopes
- Lead flashings
- Flat roof details
- Rooflights and dormers
- Chimney stacks
- The roof space
- Valleys and parapet gutters
What we do, step by step
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit usually takes between one and two hours, more where the leak is intermittent or the roof is large. For a visit in Dorking, we need access to the loft, any rooms with leaks or stains, and the outside of the building. If there is a side gate or a rear garden, let us know how to reach it. Weekday and weekend visits are available.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Dig out any old roof reports or invoices
- Have any questions written down, so nothing gets missed
- Buyers: confirm access with the estate agent or seller

Advice
How we price roof leak investigations
When we price a survey, we consider:
- How complicated the roof is, with its valleys, chimneys and parapets
- Basic, Standard or Premium
- Any need for thermal images or a drone flight
- Whether it is a home or a commercial building
Every price we give includes VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Size, height and access decide where your roof falls.
What we need to know
If you can, have these to hand when you contact us:
- Pictures of the roof from a safe spot, if you have them
- Any deadline, like an exchange date
- Any stains, drips or damp patches you’ve seen indoors
- The kind of building and roof involved
Once you know what you need, phone 07833 053749 or drop us an email. We will suggest a package, agree the price and find a date, weekday or weekend.
Roof leak investigations in Dorking: local notes
About 2.7 miles north-west lies Polesden Lacey, a reminder of how long the area around Dorking has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Knowing the roof type helps narrow down where water may be getting in.
If you own a rental within reach of Dorking Deepdene station, a tenant living with a leak needs the cause found, not just the stain painted over. If you live in an older home near Church of St Paul, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
Dorking is about 10 miles north-west of Crawley, in Surrey. Bookings from Dorking are handled just like any other: a call or an email, a price, then a date. Dorking is one of the towns and villages in Surrey where we work for roof leak investigations. You can also see our page for Crawley.

Local landmarks in Dorking
Typical jobs here are in homes near The Wheatsheaf Public House, The Ashcombe School and Deepdene Terrace and the streets around them. Other local landmarks include The Ashcombe School (0.6 miles north) and Pippbrook House (0.5 miles north). The closest station to Dorking is Dorking Deepdene station, about 0.6 miles north of the centre. Nearby you’ll also find Mesolithic Museum (3.9 miles south-west) and Headley Court (4.8 miles north-east). The countryside around Dorking includes Reigate Heath and Box Hill.
Why get it checked now?
Patching the spot above the stain often doesn’t work. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first, so the repair is aimed at the right place. Roof faults found early can be planned for, whereas a leak tends to force the timing on you.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you need to know.
