How a roof leak investigation works in Charlwood
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. Typical surveys look at water that shows only in certain storms and water through the ceiling under a flat roof, across lead flashings, rooflights and dormers and the roof space.
Many homes in small places like Charlwood face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

When to book a survey in Charlwood
Flat roofs fail with age and wear. Felt frequently lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Leaks frequently start at the edges, upstands and outlets.
A survey can pick up problems like:
- Drips in the loft during heavy rain
- Leaks that appear only in driving rain
- Damp walls below an overflowing gutter
- Water through the ceiling under a flat roof
Landlords with a home close to Ifield station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

Common questions in Charlwood
Is my home in Charlwood listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 cover smaller places like Charlwood?
Yes, Charlwood is covered. We work right across London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
What does a roof survey cost?
Roof leak investigation starts from £150, including VAT. What you pay for your roof depends on its size, height, access and the package.
How long does a roof leak investigation take?
On site, it normally takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Will you go up on the roof?
Only if it is safe. We check everything that can be seen safely: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
Can you always find the source?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but some only appear in certain weather. We report what we found and the likeliest sources.
How we price roof leak investigations
The price reflects the time and kit the roof needs. The main factors are:
- How many separate roofs there are, like extensions, dormers and garages
- Whether you choose the Basic, Standard or Premium Survey
- House, block, shop or office
- Chimneys, valleys, parapets and other details
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.
Getting in touch
A few details help us point you to the right survey and price. When you contact us, it helps to mention:
- The style of property, from a terrace to a block
- When you need the report by
- How the loft is reached, if there is one
- What made you get in touch
Our price is from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or use the contact form with the details.
The survey, step by step
It helps to start with what’s prompted the survey: 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. Most visits take an hour or two, more where the leak is intermittent or the roof is large. Rural addresses near Charlwood can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Keep pets inside or away from the areas we’re looking at
- Find any records of previous roof work
Book a survey
Booking is simple: just call 07833 053749 or drop us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Advice
Checking the roof from the ground
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Wind, rain and roofs in Charlwood
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Each of these roof types has its own typical places for water to get in.
Anyone responsible for a site like Charlwood Village Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. If you run a business near County Mall, a leak can close part of a shop or office, so finding the cause quickly matters.

Tips from our surveys
Nothing here needs a ladder. Our suggestions:
- Let us know what has already been tried
- Stay off ladders and the roof
- Catch drips in a bucket and protect the floor
- Record whether it leaks in every downpour or only some
We email the report to you. It sets out where we believe the water is getting in, how it’s travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
