How a roof leak investigation works in Forty Green
We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. If you’ve noticed water dripping from rafters or underlay and leaks that appear only in driving rain, a survey will tell you what’s going on.
For a small place like Forty Green, the inspection is the same as anywhere: the journey and access are just planned in advance. It helps to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

Tips that help
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Let us know what has already been tried
- Clear the loft hatch so we can get in
- Photograph the stain each time it appears
- Do not touch fittings that water is reaching
If condensation is the cause, we explain it, with recommendations on ventilation. That avoids roof work that wouldn’t help.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours, more where the leak is intermittent or the roof is large. Somewhere as small as Forty Green, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around 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 viewpoint.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Buyers: confirm access with the estate agent or seller
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked

Honest limits
It helps to know what a survey won’t do before you book:
- Leaks that only appear in weather we cannot recreate
- The repair itself (the investigation finds and reports the cause)
- Leaks from plumbing, tanks or pipework rather than the roof
If in doubt, call 07833 053749 or drop us an email and we’ll point you to the right survey. What our survey covers.
Roof types and parts we check
- Lead flashings
- Flat roof details
- Valleys and parapet gutters
- Rooflights and dormers
- Slate and tile slopes
- The roof space
- Chimney stacks
Why get it checked now?
Patching the spot above the stain frequently doesn’t work. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work. For older village homes like those around Forty Green, the right replacement materials are not always easy to find quickly. That’s one more reason to find defects before they become urgent.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.

Forty Green questions
How do I find out if my home in Forty Green is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you carry out roof surveys in Forty Green?
Yes. We cover the whole of London and South East England, and Forty Green is part of that. You can ring 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
Could my leak actually be condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or send us an email.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
