Roof leak investigation in Chichester: what you get
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt frequently lasts around 15 to 20 years, so age is part of the picture. We survey chimney stacks, valleys and parapet gutters and the roof space, and common reasons people get in touch are leaks that appear only in driving rain and staining around the chimney inside.
Extensions, dormers and conservatories are common on houses in towns like Chichester, and where an extension meets the house is a common leak point. The flashings and upstands at those joints get a close look. Water can run along the top of a wall or a joist before it shows, so the stain isn’t always the place to look.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Why get it checked now?
Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Extensions and dormers on homes around Chichester often hide the first signs of trouble at their joints with the main roof. Left for a few seasons, it can spoil plaster, skirting and flooring inside.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you want to find out.

Common questions in Chichester
Is Chichester in the area you cover?
We do. The survey and report are the same in Chichester as anywhere else.
Do roofs near the sea, like those around Chichester, take more of a battering?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Ridges, verges, flashings and fixings are where it usually shows, and Chichester is within about 5 miles of the coast.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
How many surveys have you done?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
How should I prepare for the leak investigation?
Keep a note of when it leaks, and take photos. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking.
How the survey changes by roof type
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
What a roof leak investigation does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks that only appear in weather we cannot recreate
- Whether rotten timbers meet design loads
- Carrying out the fix

What a roof leak investigation looks like in Chichester
Chichester is within about 5 miles of the coast, so there’s more wind and more salt in the air than further inland. Driving rain off the sea can be pushed into gaps that stay dry in calmer weather, while salt slowly corrodes metal fixings and flashings. The wider area around Chichester has a long history of building, with Goodwood House about 2.7 miles north-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If you let a flat or house near Chichester station, a tenant living with a leak needs the cause found, not just the stain painted over. Anyone responsible for a site like Lancastrian Infant School will know that a leak through a large roof is frequently found some distance from where the water shows inside. If yours is one of the older homes in the streets near Church of St Paul, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Chichester is about 27 miles east of Southampton, in West Sussex. We carry out roof leak investigations in Chichester for houses, flats, blocks and commercial buildings. Across West Sussex, we cover Chichester. You can also see our page for Portsmouth.
Roof leak investigations in PO19, PO20, PO18 and PO10 work the same way as everywhere else we cover. Whether your property is on St Martin's Square, Market Road and Old Market Avenue or anywhere close by, we can help. With the A27 and A259 close by, Chichester is easy for us to reach. We also cover Portfield (1 mile east), Westhampnett (1 mile north-east), Shopwyke (2 miles east), Maudlin (2 miles north-east) and East Lavant (2 miles north). Within a short drive, we also cover Bognor Regis (5 miles south-east), Selsey (7 miles south), Littlehampton (11 miles east), Emsworth (7 miles west), Rustington (12 miles east) and Storrington (15 miles east). Being one of West Sussex’s larger places, Chichester has every kind of building, from houses and flats to offices.
What’s near Chichester
Around Chichester, our work takes us to homes and buildings near Chichester High School For Girls, George and Dragon Inn and Central C of E Junior School. The closest station to Chichester is Chichester station, roughly 0.6 miles south. Other landmarks nearby include Novium Museum (less than half a mile south) and Chichester Castle (under half a mile east). Not far away are Stoke Down and Kingley Vale National Nature Reserve.
How it works
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes roughly 1–2 hours for most houses, rising to roughly 3–4 hours on a commercial building. Most visits in a town like Chichester start at the front of the house and work round to the back. The back garden is often where extensions, dormers and rear slopes are best seen, so unlocked gates help. Then, if it can be reached safely, we look in the loft.

Useful tips for Chichester property owners
A survey works best with a little help from you, before and after. Tips:
- Have an electrician check any wet fittings
- Mention any plumbing above the damp area
- Put a bucket under the drip and move valuables
- Mention earlier attempts to fix the leak
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant.
Don’t block the vents at the eaves. Air movement keeps condensation down, which is often mistaken for a leak. Keep insulation clear of the eaves.
