About our roof leak investigation in Loudwater
The aim is to find where the water is getting in and explain it. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. We find and report the source, while the repair is a separate matter. We survey the roof space, lead flashings and slate and tile slopes, and the problems we are asked to look at most are leaks that appear only in driving rain and damp ceilings under a flat roof.
Many homes in small places like Loudwater face open ground, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible.

What happens if roof problems are left?
A leak near lights or wiring needs attention quickly. Keep away from any fitting that water is reaching. Finding where the water is getting in should follow straight away. Where a roof is exposed, as many are in small places like Loudwater, driving rain gets into any weakness, and damp in older walls is slow to dry out.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Why us?
- 5,000+ surveys completed
- Thermal imaging and drones used where they help
- Photos and a written report every time
- More than 20 years surveying roofs

What affects the cost of roof leak investigations
Several things affect the price of a survey:
- Whether it is a home or a commercial building
- Which survey package you book
- How many separate roofs there are, such as extensions, dormers and garages
- Height and safe access
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before you book.
What to let us know when you get in touch
Getting the details right at the start saves time. It helps to include:
- Where the property is, with the postcode
- What kind of property and roof it is
- Pictures from the garden or a window, if you have them
- Access details, such as a loft hatch or a shared roof
Most bookings start with a short call: ring 07833 053749 or drop us an email. You’ll have a price before anything is arranged.
FAQs for Loudwater
Will you come out to Loudwater?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
How do I find out if my home in Loudwater is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you use drones?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.
How do I arrange a roof leak investigation in Loudwater?
To arrange a survey, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
Is thermal imaging part of a leak investigation?
We use thermal imaging where it helps, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Checking the roof from the ground
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
How it works
Every roof is different, but as a rough guide the survey takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. If you have questions on the day, just ask. Somewhere like Loudwater needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it’s safe.
- 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.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- We email a written report showing where the water most likely gets in.
How to prepare
- Dig out any old roof reports or invoices
- Leave a clear route to the loft
- Let us know about parking near the property
How to book
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.

When to book a survey in Loudwater
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. On slate roofs, slipping is often caused by corroded nails.
A survey can pick up problems like:
- Damp underlay across a wide area
- Damp patches next to the stack
- Water dripping from rafters or underlay
- Water coming in around a roof light or dormer
For businesses in and around places such as Charter Place, finding where water is getting in quickly keeps disruption down.
Before you book any roof surveyor
- How long they’ve been surveying roofs
- How they plan to inspect the roof safely
- Whether you get a written report with photos
- Their insurance cover
Roof leak investigations in Loudwater: local notes
About 2.5 miles north-west lies Chenies Manor House, a reminder of how long the area around Loudwater has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. The covering and its details give the first clues when tracing where water is coming from.
Take an older house close to Christ Church: water on an older roof tends to find its way in at the lead, the valleys or the chimney. For landlords with property near Rickmansworth station, a tenant living with a leak needs the cause found, not just the stain painted over.

What a roof leak investigation doesn’t cover
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- What’s under the covering or behind the plaster
- Leaks from plumbing, tanks or pipework rather than the roof
- Leaks that only appear in weather we can’t recreate
