About our roof leak investigation in Landport
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. We check parapets, valleys and flashings from every safe viewpoint. Our report shows what we found, with photos. Common reasons to book are water coming in around a roof light or dormer and damp ceilings under a flat roof, on rooflights and dormers, chimney stacks and flat roof details.
In a smaller place like Landport, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. A leak that only appears in certain weather often points to an exposed detail. Let us know when it happens when you get in touch. Gutters and downpipes on the exposed side are worth a look as well.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What happens if roof problems are left?
Damp in a ceiling or loft can lead to mould. It is unpleasant, and it’s harder to deal with once established. Finding the leak comes first. On a bungalow or cottage around Landport, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
All our prices include VAT. Prices start from £150, including VAT. We confirm the price for your survey before booking.

How it works
After the inspection, everything we found is written up as a written report with photos, sent to you by email. On timing, most surveys take about one to two hours for most houses, rising to roughly 3–4 hours on a commercial building. With a bit of garden around a house, as there often is around Landport, the roof can be viewed from several angles. Mention any side of the property we can’t get to. The loft, where there’s safe access, completes the picture.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around 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.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- Check the loft hatch can be reached
- Dig out any old roof reports or invoices

Roof leak investigations around Landport
Landport lies within about 1 mile of the sea, so there is 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. Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If you look after a shop, office or commercial unit, for example near Tricorn Centre, a leak can close part of a shop or office, so finding the cause quickly matters. If you live near a park such as Alexandra Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching. If you look after a building like Ark Dickens Primary Academy, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Landport is about 1 mile south-west of Portsmouth, in Portsmouth. Anywhere in Landport, we can come and survey your property, on a weekday, Saturday or Sunday. Landport is one of the places in Portsmouth we cover for roof leak investigations.

Landport questions
Do you cover smaller places like Landport?
We do. Villages and rural addresses get the same survey as a town house.
How do I find out if my home in Landport is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can you survey a shared roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We can only inspect what we are given access to.
Is the repair included in the leak investigation?
A leak investigation finds and reports the likely source. The repair is not part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch.
What we cannot see
It’s a careful look at the leaking roof, not the whole story. Its limits include:
- Leaks from plumbing, tanks or pipework rather than the roof
- A promise to find every leak on a single visit
- Structural calculations (that’s a structural engineer’s job)
If in doubt, ring 07833 053749 or use the contact form and we will suggest the right survey before you book. The full list of what we check.

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Write down the wind direction and rain when it leaks
- Protect furniture and flooring under the leak
- Don’t touch fittings that water is reaching
- Clear the loft hatch so we can get in
If condensation is the cause, we explain it, with recommendations on ventilation. That avoids roof work that wouldn’t help.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
Checking the roof from the ground
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
How the survey changes by roof type
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Slate and tile slopes
A gap in the coverings exposes the underlay. Ageing felt eventually lets water through.
