How a roof leak investigation works in Blacknest
The aim is to find where the water is getting in and explain it. You get a report with photos showing the likely entry point and the route the water is taking, and recommends what should be done. It gives any roofer a clear brief. The investigation finds and explains the cause, while the repair is a separate matter. Typical surveys look at leaks below a flat extension roof and water coming in around a roof light or dormer, on rooflights and dormers, valleys and parapet gutters and chimney stacks.
Roofs in small places like Blacknest often stand in the open, so storms hit ridges, verges and chimneys hard. 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.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Blacknest: your questions answered
Is Blacknest in the area you cover?
Yes, Blacknest is within the area we cover. We survey roofs across London and the South East. You can ring 07833 053749 or drop us an email with the address and a few details.
Is my home in Blacknest listed or in a conservation area?
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.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Mention it when you contact us and we will plan the survey around it.
What’s the best way to book?
Just ring 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date.
How much does a roof leak investigation cost in Blacknest?
Roof leak investigation starts from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, confirmed before anything is booked.
Is it a structural engineer’s report?
No. We point out what can be seen, like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Leaks and storm damage in Blacknest
Farnham Castle, about 4.1 miles north-east, is one of the historic houses in the wider area around Blacknest. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. A number of Hampshire villages keep thatched roofs on their older buildings. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. The covering and its details give the first clues when tracing where water is coming from.

For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Should I look at the roof myself first?
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
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.

What happens if roof problems are left?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. Tracing it now lets you plan the work rather than react to it. Outbuildings and barns around Blacknest are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.

What happens on the day
We don’t take risks to get a closer look. We inspect everything that’s safely in view, and if part of the roof cannot be seen, the report says so. Most visits take an hour or two for most homes, though a hard-to-trace leak can take longer. Older roofs in small places like Blacknest can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Preparing for the visit
- For flats, make sure roof access has been agreed
- Jot down any questions you want answered
- Have any paperwork from past roof work to hand

Advice
Signs you need a roof leak investigation in Blacknest
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Common reasons to book include:
- Water that shows only in certain storms
- Drips in the loft during heavy rain
- Damp on a chimney breast
- Drips from nail tips in a cold loft
For landlords with property near Bentley (Hampshire) station, a clear finding on where water gets in helps you brief a roofer straight away.
What to check before booking
- What the survey will not cover
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether the inside of the roof is included
- What the report includes, and whether it has photographs
What a survey costs
Prices vary from roof to roof, and it comes down to:
- The size of the roof
- The package you choose: Basic, Standard or Premium
- The height of the building and how the roof can safely be seen
- Features like valleys, chimneys, dormers and parapets
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
We will typically ask about:
- The kind of building and roof involved
- The property’s address and postcode
- Access details, such as a loft hatch or a shared roof
- Why you want a survey: buying, a leak, a storm or new work
Our price is from £150, including VAT. The exact figure depends on the roof and the package, so phone 07833 053749 or use the contact form with the details.
