About our roof leak investigation in North Holmwood
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. We check each likely route and we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. We check all of them, from each safe vantage point. Typical surveys look at damp ceilings under a flat roof and staining where a gutter or parapet meets the wall, on valleys and parapet gutters, the roof space and rooflights and dormers.
Houses in smaller places like North Holmwood can stand more in the open, where driving rain gets into any gap at a ridge, verge or flashing. A leak that only appears in certain weather often points to an exposed detail. Let us know when it happens when you get in touch. Gutters and downpipes on the exposed side are worth a look as well.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

How it works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours for a house, with bigger or more complicated roofs taking longer. Some parts of a survey depend on the weather, so a visit to North Holmwood is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- Outside, we look at every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- We email a report with photographs, the likely entry point and recommendations.
Before the survey
- Clear the way to the loft hatch
- Point out any leaks or damp patches
- Buyers: confirm access with the estate agent or seller

North Holmwood questions
Will you come out to North Holmwood?
Yes, North Holmwood is covered. We survey roofs across London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Do you cover North Holmwood?
Yes. We cover the whole of London and South East England, and North Holmwood is part of that. You can ring 07833 053749 or send us an email with the address and some details.
How do I book a survey in North Holmwood?
To arrange a survey, call 07833 053749 or use the contact form and tell us the address and what you’d like to know. We’ll confirm the price and find a day that suits.
Is it a leak or condensation?
It is a common question. A leak normally shows in one area and follows rain, while condensation is often spread out and worse in cold weather. The report explains which it looks like and what to do.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. 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. We always check what it shows with moisture readings.
Why it is worth a survey now in North Holmwood
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it is harder to clear. Finding the leak comes first. In a smaller place like North Holmwood, wherever a roof is exposed, a loose ridge or flashing doesn’t stay loose for long. Wind gets under it and lifts more.
All our prices include VAT. Roof leak investigation starts from £150, including VAT. We confirm the exact price before booking.

How the survey changes by roof type
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely.
Valleys
Valleys collect water from two roof slopes. Worn or split linings and slipped valley tiles let it under the coverings.
What affects the cost of roof leak investigations
When we price a survey, we consider:
- How complicated the roof is, with its valleys, chimneys and parapets
- How tall the building is and how easy the roof is to see
- If the survey needs thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. The price for your roof depends on its size, access and what you want to find out.
What we need to know
What helps most when you contact us:
- Any stains, drips or damp patches you’ve seen indoors
- The reason for the survey, such as buying, a leak or storm damage
- How the loft is reached, if there is one
- Pictures from the garden or a window, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or email us with the address and the days you’d prefer.
What we cannot see
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- A structural engineer’s report
- Carrying out the fix
- A promise to find every leak on a single visit
If in doubt, phone 07833 053749 or send us an email and we’ll recommend the right survey. What a survey covers and does not.
What we check
- Rooflights and dormers
- Chimney stacks
- Valleys and parapet gutters
- Lead flashings
- Slate and tile slopes
- The roof space

Roof leak investigations in North Holmwood: local notes
About 3.8 miles north-west lies Polesden Lacey, a reminder of how long the area around North Holmwood has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
A roof leak in a hotel or guest house around North Holmwood means lost rooms as well as repairs, so it is worth knowing the roof’s condition. If you own a rental within reach of Dorking West station, a tenant living with a leak needs the cause found, not just the stain painted over.

Signs you need a roof leak investigation in North Holmwood
A chimney stack has plenty of places for rain to get in. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. The damp may appear on a chimney breast, a ceiling or in the loft.
People typically book a survey after spotting something like this:
- Stains around a skylight
- Water through the ceiling under a flat roof
- Wet patches on loft insulation
- Staining around the chimney inside
Take an older house close to Church of St John the Evangelist: leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
