Roof leak investigation in Portslade, West Sussex
We carry out roof leak investigations in Portslade and the rest of West Sussex. We survey on any day of the week.
- Drips in the loft during heavy rain
- Damp ceilings under a flat roof
- Ceiling stains that grow after rain
When to book a survey in Portslade
Flat roofs fail with age and wear. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
A survey makes sense if you’ve noticed:
- Water through the ceiling under a flat roof
- A leak that comes and goes with the weather
- Staining where a gutter or parapet meets the wall
- Drips from nail tips in a cold loft
The streets around a church such as St Nicolas Church are often among the oldest in a place, and if yours is one of the older homes nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Questions to ask before booking
- What they will not be able to tell you
- Their insurance cover
- Which parts of the roof they’ll actually see
- Will they check the loft as well as the outside?
Roof leak investigation in Portslade
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, such as tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. If you’re worried about wet patches high on an inside wall and drips from nail tips in a cold loft, we can find out what’s behind it, on flat roof details, lead flashings and slate and tile slopes alike.
In older homes around places like Portslade, the underlay may be old bitumen felt, or there may be none at all. Once the slates or tiles let water past, there is little to stop it reaching the ceiling. Finding where it gets in, and whether it’s old wear or new damage, decides what comes next. In the loft, damp battens or wet insulation are often the first clues.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Prices for roof leak investigations in Portslade
We confirm the price for the job before booking. This is what makes a difference:
- The package you choose: Basic, Standard or Premium
- The size of the roof
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
Before you get in touch, it helps to have:
- The address and postcode of the property
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
- The kind of building and roof involved
Photos help, if you have them. Take them safely from ground level or a window. To get started, ring 07833 053749 or drop us an email.
Different roofs, different checks
Chimney stacks
Our chimney check is a visual inspection of the stack, and it isn’t a flue or gas safety check.
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
Portslade: your questions answered
Does being near the coast affect roofs in Portslade?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch.
Is Portslade within the area you cover?
Yes, we do. 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.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair itself is a separate job. The report shows where the water gets in and what should be done.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put by urgency where it matters.
What does a roof survey cost?
Roof leak investigation starts from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT.
Could my leak actually be condensation?
It is a common question. Leaks tend to follow wet weather and show in one place, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Will you definitely find the leak?
We cannot promise to find every leak on one visit. Most leave clues we can follow, but intermittent leaks that need particular weather can be harder. The report sets out what we found and the most likely routes.

Wind, rain and roofs in Portslade
Portslade is within about 1 mile of the coast, and places near the sea get more salt in the air and more wind than inland. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. The covering and its details give the first clues when tracing where water is coming from.
Shop and office owners around Churchill Square may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. Landlords with a home close to Fishersgate station may find that a clear finding on where water gets in helps you brief a roofer right away.

How the survey works
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, using the ground, windows, the loft and a drone where applicable. The survey usually takes an hour or two for most houses, though large, tall or awkward roofs take more time. Being in a smaller place like Portslade does not 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 pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Before we arrive
- Tell us about any leaks, stains or damp patches you know of
- Dig out any old roof reports or invoices
- Have keys ready for side gates, garages or roof access doors
