Leaks and storm damage in Calshot
Calshot is within about 1 mile of the coast, and being near the sea means more wind and salt than a roof inland would face. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave, while salt slowly corrodes metal fixings and flashings. About 4.9 miles south-east lies Osborne House, a reminder of how long the area around Calshot has been built on. 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.
Landlords with a home close to Hamble station may find that a tenant living with a leak needs the cause found, not just the stain painted over. For an older house near a landmark like St George, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

About our roof leak investigation in Calshot
Not every drip is a leak. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. We are often asked to look into damp walls below an overflowing gutter and drips in the loft during heavy rain, across slate and tile slopes, valleys and parapet gutters and the roof space.
For a small place like Calshot, the inspection is the same as anywhere: we simply plan the journey and access ahead. It’s useful to know where the water appears, in what weather, and what you’ve seen outside, along with any repairs done before. If you have photographs of the water coming in, they help as well.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put in order of urgency where relevant.

How it works
We don’t take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. Most visits take about one to two hours at a typical home, and more on a big or complicated roof. Somewhere as small as Calshot, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Let us know about parking before the day
- Gather any invoices or paperwork from past roof work
- Check pets are kept safely away

Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or email us.
Related advice
What we look for on each type of roof
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. If it is too low, cracked or poorly dressed, water gets behind it.
Slate and tile slopes
A gap in the coverings exposes the underlay. Ageing felt eventually lets water through.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
Honest limits
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Plumbing leaks that look like roof leaks
- Whether rotten timbers meet design loads
- Leaks that only appear in weather we can’t recreate

FAQs for Calshot
Do roofs near the sea, like those around Calshot, take more of a battering?
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.
How do I find out if my home in Calshot is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How long does the visit take?
On site, it typically takes about one to two hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
What insurance do you have?
Our cover is professional indemnity plus public liability.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
For landlords and managing agents
Landlords and letting agents in Calshot book surveys as well as homeowners. A report with photographs gives you a clear record of the leaking roof, useful for planning maintenance.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
