About our roof leak investigation in Sandown
Some ‘leaks’ aren’t leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, and the stains look much like a leak. Knowing which it is means the right fix can be done, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. If you’re worried about water marks that spread in wet weather and drips from nail tips in a cold loft, a survey will tell you what’s going on.
Houses in smaller places like Sandown can stand more in the open, so wind and driving rain find any weakness in ridges, verges and flashings. A leak that only appears in certain weather frequently points to an exposed detail. It helps to know when and where the water appears. Gutters and downpipes on the exposed side are worth a look as well.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

Roof leak investigations around Sandown
Sandown lies within about 1 mile of the sea, so there is more wind and more salt in the air than further inland. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave. With Morton Manor about 1.5 miles north-east, Sandown sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings such as The Bay Church of England School, a leak through a large roof is often found some distance from where the water shows inside. For hotels and guest houses around Sandown, a roof problem found early is far less disruptive than one found by a guest.
Sandown is about 10 miles south of Gosport, in the Isle of Wight. In Sandown, as across the Isle of Wight, every roof gets the same careful survey. Our area takes in places right across the Isle of Wight, from the larger towns to small villages. Our Portsmouth page covers surveys nearby.

Before and after the survey
You don’t need to be a roofer to help. Here’s what helps most:
- Don’t touch fittings that water is reaching
- Photograph the stain each time it appears
- Move stored items away from the hatch
- Write down the wind direction and rain when it leaks
Any roofer you ask to quote can work from the report. They’ll see exactly where the problem is, rather than at the stain.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
What happens on the day
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes an hour or two, more where the leak is intermittent or the roof is large. With a bit of garden around a house, as there often is around Sandown, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- You let us know where the water shows and when it appears.
- We look at 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.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Getting ready for the survey
- Keep pets inside or away from the areas we’re looking at
- Note where any stains or damp appear
- For flats, check roof access has been agreed

When to book a survey in Sandown
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Common reasons to book include:
- A leak that comes and goes with the weather
- Drips from nail tips in a cold loft
- Leaks at a dormer or roof window
- Staining around the chimney inside
For an older house near a landmark like Christ Church, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Questions from Sandown
Is Sandown within the area you cover?
Yes, Sandown is covered. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Do roofs near the sea, like those around Sandown, take more of a battering?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Ridges, verges, flashings and fixings are where it usually shows.
Will you definitely find the leak?
Not always, and we’ll be honest about that. Some leaks hide well, particularly those that need wind-driven rain. Where the source isn’t certain, we list the likely routes in order.
Does the report include photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Will you fly a drone over my roof?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
How long will you be at the property?
It normally takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Report times depend on the package.
How much does a roof leak investigation cost in Sandown?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose.
What a survey costs
All our prices include VAT. The things that change the price are:
- Basic, Standard or Premium
- Features like valleys, chimneys, dormers and parapets
- The number of roofs, including extensions and garages
- Building height and the viewpoints available
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
What to let us know when you get in touch
Getting the details right at the start saves time. Please include:
- What made you get in touch
- Where the property is, with the postcode
- Your timetable, such as an exchange date
- What kind of property and roof it is
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
What you can safely check yourself
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
