Alverstoke Roof Leak Investigation

Roof leak investigation in Alverstoke: what you get
Water is good at hiding where it gets in. Water frequently travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back, one likely route at a time. Patching the spot above the stain often misses the real cause. Tracing the route first means any work can be aimed at the right place. We survey slate and tile slopes, the roof space and lead flashings, and common reasons people get in touch are stains around a skylight and drips from nail tips in a cold loft.
Roofs in small places like Alverstoke often stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

Alverstoke questions
Will you come out to Alverstoke?
Yes, Alverstoke is on our map. A small place gets exactly the same survey as a big one.
Is my home in Alverstoke listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
What does a roof survey cost?
Prices start from £150, including VAT. We confirm the price for the job before booking, and it depends on the roof’s size, access and the package you choose. To get a price, phone 07833 053749 or drop us an email.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
What do I do with the report?
You’ll get the report by email, with photos and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.

How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. In a hamlet or village like Alverstoke, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- 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.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
How to prepare
- Check pets are kept safely away
- Have any questions written down, so nothing gets missed
- For a flat or shared roof, check access with the building owner or managing agent
Booking a survey

Advice
Roof leak investigations around Alverstoke
Alverstoke is within about 1 mile of the coast, and being near the sea means more wind and salt than a roof inland would face. 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. Different coverings let water in at different points, which shapes where the search starts.
For site and facilities teams at buildings such as Alverstoke Community Infant School, on a building that size, finding the source of a drip means looking well beyond the stain. The streets around a church such as The Little Church are often among the oldest in a place, and if your house is among the older ones nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Alverstoke is about 2 miles south of Gosport, in Hampshire. Alverstoke is part of the area we cover and the surrounding area as part of our work across London and South East England. Our Hampshire coverage includes Alverstoke and the places around it.

Why get it checked now?
A leak that returns after a repair normally means the real source wasn’t found. We look past the obvious spot and check each likely route. It gives the next repair a far better chance. Where a roof is exposed, as many are in small places like Alverstoke, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.

- The repair itself (the investigation finds and reports the cause)
- Plumbing leaks that look like roof leaks
- What’s under the covering or behind the plaster

Prices for roof leak investigations in Alverstoke

What to let us know when you get in touch
Getting the details right at the start saves time. Please include:
- Access details, such as a loft hatch or a shared roof
- Photos of the roof, taken safely from ground level or a window
- What’s prompted the survey
- Dates you’re working to, such as exchange
Unsure which package suits your roof? It is easiest to phone 07833 053749 or email us and describe the roof and what’s worrying you. We will talk you through the options and what they cost.
Before and after the survey
Small things make a difference. Our tips:
- Note the weather when the leak shows
- Let us know if there are tanks or pipes in the loft
- Take dated photos of the leak
- Put a bucket under the drip and move valuables
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. It’s a chance to ask about anything in the report.
Keep gutters, valleys and outlets clear, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
What we are asked to look at in Alverstoke
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, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Common reasons to book include:
- Drips in the loft during heavy rain
- Stains around a skylight
- Water through the ceiling under a flat roof
- Drips from nail tips in a cold loft
For landlords with property near Portsmouth Harbour station, tracing a leak quickly matters when a tenant is living with it.
