Roof leak investigations in Force Green: local notes
About 0.8 miles south lies Quebec House, a reminder of how long the area around Force Green has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
For an older house near a landmark such as Church of St Mary the Virgin, the leak may come from a chimney, a valley or tired lead rather than the covering itself. For landlords with property near Oxted station, tracing a leak quickly matters when a tenant is living with it. For a London address like Force Green, it is useful to know about controlled parking before the day.

How a roof leak investigation works in Force Green
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, while the repair is a separate matter. We survey valleys and parapet gutters, rooflights and dormers and lead flashings, and common reasons people get in touch are damp on a chimney breast and staining where a gutter or parapet meets the wall.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Force Green, we inspect what we can reach safely and are given access to. It is useful to know when the water appears and in what weather.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What we do, step by step
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You tell us where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Leave a clear route to the loft
- If you’re buying, let the agent know when we are coming
- Mention any parking restrictions on your street
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email.
Advice
Useful tips for Force Green property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Put a bucket under the drip and move valuables
- Record whether it leaks in every downpour or only some
- Clear the loft hatch so we can get in
- Mention any plumbing above the damp area
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. That avoids roof work that wouldn’t help.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
Checking the roof from the ground
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book.
Landlords, agents and block managers in Force Green
Freeholders and residents’ companies use a roof report to plan and budget.
Where a roof is shared: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we’ll plan the survey around it.
Roof by roof
Valleys
Leaves and moss build up in valleys and hold water back. In heavy rain, it can spill under the edges of the slates or tiles.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Rain can then run in at the ridge.
What affects the cost of roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:
- Commercial roofs and larger buildings
- Any need for thermal images or a drone flight
- The number of roofs, including extensions and garages
- Height and safe access
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
Before you get in touch, it helps to have:
- Where the property is, with the postcode
- Where any leaks, stains or damp patches show inside
- The style of property, from a terrace to a block
- Photos of the roof, taken safely from the ground or a window
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, ring 07833 053749 or email us.
Force Green questions
Can parking be tricky for a visit in Force Green?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Force Green?
We do. The survey and report are the same in Force Green as anywhere else.
Can you find a leak when it isn’t raining?
In most cases, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
How should I prepare for the leak investigation?
Keep a note of when it leaks. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
What happens next?
The report arrives by email, with photographs and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
