How a roof leak investigation works in Portchester
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. Common reasons to book are water that shows only in certain storms and damp on a chimney breast, across the roof space, rooflights and dormers and chimney stacks.
In a smaller place like Portchester, 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. It is useful to know when and where the water appears. Gutters and downpipes on the exposed side are worth a look as well.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Why act early in Portchester
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. Tradespeople may need to travel further to a smaller place like Portchester, so it’s useful to plan roof work rather than call someone out in a hurry. A survey gives you that notice.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. Size, height and access can affect the price too.

Leaks and storm damage in Portchester
Portchester lies within about 1 mile of the sea, so there’s more wind and more salt in the air than further inland. In a coastal gale, rain is driven sideways into laps, verges and flashings. A number of Hampshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently 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 Castle Primary School, a leak through a large roof is frequently found some distance from where the water shows inside. For landlords with property near Portchester station, tracing a leak quickly matters when a tenant is living with it.

Common roof problems in Portchester
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. On slate roofs, slipping is frequently caused by corroded nails.
We are often asked to look at:
- Water coming in around a roof light or dormer
- Damp on a chimney breast
- Water dripping from rafters or underlay
- Damp walls below an overflowing gutter
If you run a business near Fareham Shopping Centre, a leak can close part of a shop or office, so finding the cause quickly matters.
Questions to ask before booking
- What happens after the report arrives
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Their track record with similar roofs
- Which limits apply to the survey
When you need someone else
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether rotten timbers meet design loads
- Faults hidden behind ceilings or boarding
- Leaks that only appear in weather we can’t recreate
If in doubt, call 07833 053749 or send us an email and we’ll point you to the right survey before booking. What our survey covers.

How we price roof leak investigations
The price reflects the time and kit the roof needs. The main factors are:
- The use of thermal imaging or a drone
- Features like valleys, chimneys, dormers and parapets
- How many separate roofs there are, such as extensions, dormers and garages
- Roof area
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, with VAT included. We’ll tell you which package suits the questions you have.
Helping us price your survey
We’ll typically ask about:
- Your postcode, so we can check access and travel
- The kind of building and roof involved
- Any stains, drips or damp patches you’ve seen indoors
- The reason for the survey, such as buying, a leak or storm damage
Not sure which survey you need? It is easiest to ring 07833 053749 or use the contact form and describe the roof and what’s worrying you. We’ll explain the options and the price.
The survey, step by step
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Being in a smaller place like Portchester doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- You tell us where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Getting ready for the survey
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at
- Make sure we can get to the back of the property
Getting a price

Tips from our surveys
These tips come from what we see on roofs every week:
- Do not climb onto the roof to look
- Note the weather when the leak shows
- Do not touch fittings that water is reaching
- Put a bucket under the drip and move valuables
We email the report to you, with photos of what we found. It sets out where we believe the water is getting in, how it is travelling and what needs attention. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Keep gutters, valleys and outlets clear, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
Your questions about roof leak investigations in Portchester
Will you come out to Portchester?
Yes, Portchester is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do roofs near the sea, like those around Portchester, take more of a battering?
It can do. Portchester is within about 1 mile of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
Can you survey at the weekend?
We carry out surveys on any day of the week. To find a day that suits you, ring 07833 053749 or email us.
Will you fix the leak as part of this?
Our job here is to trace the leak and explain it, not to carry out the repair. With the report, a roofer knows exactly where to look.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
Why is the stain in a different place from the leak?
Because water travels. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
