Osea Island questions
Is the coastal weather around Osea Island hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Do you cover smaller places like Osea Island?
Yes, we do. We work right across London and the South East, and smaller places are part of that. Longer journeys are simply planned beforehand.
What does a roof survey cost?
Prices start from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
Why isn’t the leak directly above the stain?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it shows. Following that route is what our investigation does.
Do you use drones?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
What does the report include?
Written findings with photos, covering the condition of the leaking roof, the defects we found and what we recommend, by urgency where it matters. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Is this a RICS survey?
No. We look at the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Roof leak investigation in Osea Island: what you get
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back. A repair aimed only at the stain can miss the cause entirely. Finding the route first lets the repair go where it is needed. Common reasons to book are damp patches next to the stack and damp walls below an overflowing gutter, on rooflights and dormers, chimney stacks and flat roof details.
Being in a small place like Osea Island makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Why get it checked now?
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it’s harder to deal with once established. Finding the leak comes first. Outbuildings and barns around Osea Island are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.

Do you need a roof leak investigation in Osea Island?
When a slate slips or a tile cracks, the underlay takes the water. Old bitumen felt may cope for a while, but it tears and sags with age, and very old roofs may have no underlay at all. On slate roofs, slipping is often caused by corroded nails.
Most people get in touch after spotting something like this:
- Condensation that looks like a leak
- A leak that comes and goes with the weather
- Water marks that spread in wet weather
- Water dripping from rafters or underlay
Whether the property is in Osea Island itself or nearby, the inspection covers everything that’s safely in view, inside and out.

How it works
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit normally takes roughly 1–2 hours for most houses; commercial roofs usually need 3–4 hours. In a small place like Osea Island, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
How to prepare
- Agree roof access with the managing agent if it’s shared
- Make sure pets are kept safely away
- Point out any leaks or damp patches

What this survey can’t tell you
Some things cannot be seen without opening up the roof, so a survey has limits:
- A promise to find every leak on a single visit
- Whether rotten timbers meet design loads
- Leaks from plumbing, tanks or pipework rather than the roof
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we’ll give you a straight answer before booking. What our survey covers.

Roof leak investigations around Osea Island
The coast is about 2 miles or less from Osea Island, so there’s more wind and more salt in the air than further inland. Strong wind lifts anything already loose, and driving rain gets in wherever it can, while salt slowly corrodes metal fixings and flashings. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand.
For any home in Osea Island, it is the small, early fault that is cheapest to put right.

Should I look at the roof myself first?
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
