Your questions about roof leak investigations in Forestdale
Is my home in Forestdale listed or in a conservation area?
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.
Will parking be an issue for a roof survey in Forestdale?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it is useful, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Do you use drones?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
Can you find a leak when it is not raining?
In most cases, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
How should I prepare for the leak investigation?
Check the loft can be reached. Have any photos of the leak ready, plus details of past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
About our roof leak investigation in Forestdale
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. If you’ve noticed leaks below a flat extension roof and drips in the loft during heavy rain, we can find out what’s behind it, on slate and tile slopes, flat roof details and valleys and parapet gutters alike.
Water getting into a London home frequently comes from a detail you can’t see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you’re tracing a leak or recording storm damage in Forestdale, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

What we do, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. Most surveys take between one and two hours for most houses, or half a day or so for a commercial building. For a visit in Forestdale, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at whatever is safely visible from ground level, windows, the loft and, where it is safe, the roof itself.
- You tell us where the water shows and when it appears.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Mention any parking restrictions on your street
- Unlock side gates and any roof access doors
- Buyers: confirm access with the estate agent or seller

Common roof problems in Forestdale
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
A survey makes sense if you’ve noticed:
- Stains around a skylight
- Brown rings on upstairs ceilings
- Leaks below a flat extension roof
- Water that shows only in certain storms
If you own a rental within reach of Sanderstead station, a tenant living with a leak needs the cause found, not just the stain painted over.
Before booking any roof surveyor

Can I check my roof myself?
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 ground level.
What you can’t 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.
Roof leak investigations around Forestdale
With Addington Palace about 0.9 miles north, Forestdale sits in an area with a long building history. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Each of these roof types has its own typical places for water to get in.
For an older house near a landmark such as St Francis, water on an older roof tends to find its way in at the lead, the valleys or the chimney. For businesses in and around places such as St George's Walk, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Have an electrician check any wet fittings
- Let us know if there are tanks or pipes in the loft
- Mention earlier attempts to fix the leak
- Leave roof access to professionals
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Don’t block the vents at the eaves. Good airflow reduces condensation, and condensation is a common false alarm. Check insulation does not block airflow at the eaves.
