Roof leak investigation in Osidge
Most roof leaks start at a joint rather than the middle of a slope. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. Each one is checked from wherever it is safe to see it. If you are worried about damp patches next to the stack and damp walls below an overflowing gutter, we can find out what’s behind it, whatever the roof.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in Osidge, those hidden details are where the inspection begins. Water from a hidden gutter can run along joists and show up a room or two away.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible, with the urgent items made clear.

What to let us know when you get in touch
If you can, have these to hand when you get in touch:
- The type of building and roof, such as pitched or flat
- Why you want a survey: buying, a leak, a storm or new work
- Whether there is a loft hatch, a shared roof or tricky access
- Photos of the roof, taken safely from the ground or a window
Photos help, if you have them. Take them safely from the ground or a window. To send them or to book, call 07833 053749 or send us an email.
Why act early in Osidge
Water damage grows the longer it’s left. Damp spreads into rafters, ceilings and insulation. Finding the source early keeps the damage down. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.

What happens on the day
There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will take it from there. A typical survey takes an hour or two on an ordinary house, though large, tall or awkward roofs take more time. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Osidge runs like any other.
- We start with your notes and photos of the leak.
- Inside, we look at the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there is safe access.
- 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.
Before we arrive
- If it isn’t your property yet, arrange access through the agent
- Have keys ready for side gates, garages or roof access doors
- If the roof is shared, arrange access with whoever manages the building

Advice
Wind, rain and roofs in Osidge
About 3.8 miles south-east lies Bruce Castle, a reminder of how long the area around Osidge has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Knowing the roof type helps narrow down where water may be getting in.
Shop and office owners around Grand Arcade may find that a leak can close part of a shop or office, so finding the cause quickly matters. The streets around a church such as St Andrew's Church are often among the oldest in a place, and if yours is one of the older homes nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney. Homes near green spaces like Oak Hill Park can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.

What this survey cannot tell you
Some things cannot be seen without opening up the roof, so a survey has limits:
- Carrying out the fix
- A structural engineer’s report
- What’s under the covering or behind the plaster

What else we do in Osidge
Osidge: your questions answered
Does a conservation area affect roof work in Osidge?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is Osidge in the area you cover?
Yes, Osidge is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
How long does a roof leak investigation take?
Allow roughly 1–2 hours for most houses, and longer for a large or complex roof. We’ll confirm what to expect when we arrange the visit.
Does this replace a RICS home survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
Roof by roof
Valleys
Leaves and moss build up in valleys and hold water back. During a downpour, water can back up under the coverings.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Rain can then run in at the ridge.
