Useful tips for Blacknest property owners
These tips come from what we see on roofs every week:
- Take dated photos of the leak
- Do not touch fittings that water is reaching
- Don’t climb onto the roof to look
- Move stored items away from the hatch
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. You can ask us about anything that is not clear.
Do not block the vents at the eaves. Good airflow reduces condensation, which is often mistaken for a leak. Make sure insulation doesn’t block airflow at the eaves.
Roof leak investigation in Blacknest: what you get
We investigate roof leaks in Blacknest and across London and the South East. We visit on weekdays and at weekends. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then phone 07833 053749 or use the contact form to arrange a visit. Common reasons to book are damp walls below an overflowing gutter and water coming in around a roof light or dormer, on chimney stacks, rooflights and dormers and flat roof details.
Roofs in small places like Blacknest often stand in the open, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

FAQs for Blacknest
Do you carry out roof surveys in Blacknest?
Yes, Blacknest is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and tell us about the property, and we’ll talk through which survey suits.
Will you come out to Blacknest?
Yes. Blacknest is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you as you book.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
What should I do before you arrive?
Note when the leak appears and what the weather was doing. Clear access to the loft. Keep away from any light or socket that water is reaching.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
Why get it checked now?
Patching the spot above the stain often does not work. The real way in may be a metre or more away. We find the probable source before anyone starts work. For older village homes like those around Blacknest, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
To find out what your survey will cost, phone 07833 053749 or email us with the address and some details. We’ll confirm the figure before booking.
What you get with us
- PI and public liability insurance
- Surveys seven days a week
- An independent view of the roof
- Thermal imaging and drone inspection where they help
Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Roof leak investigations in Blacknest: local notes
With St Leonard's Hill about 4.2 miles north, Blacknest sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Knowing the roof type helps narrow down where water may be getting in.
Living close to Silwood Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls. Take a building like Holy Trinity CofE Primary School: a leak through a large roof is often found some distance from where the water shows inside.

What else we do in Blacknest
What we do, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. Most visits take an hour or two for most homes, though a hard-to-trace leak can take longer. Somewhere like Blacknest needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the loft space above it.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Unlock side gates and any roof access doors
- Mention any parking restrictions on your street

What we’re asked to look at in Blacknest
A chimney stack has a good many places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. It can show up on the chimney breast, nearby ceilings or in the loft space.
A survey makes sense if you’ve noticed:
- Drips in the loft during heavy rain
- Drips from nail tips in a cold loft
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
Take an older house close to Holy Trinity Church: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
