Flat Roof Survey in Lagness
We carry out flat roof surveys in Lagness and the rest of West Sussex. We survey on any day of the week.
- Damaged trims at the roof edge
- Splits and cracks in the covering
- Gaps at upstands and abutments
How a flat roof survey works in Lagness
Every flat roof covering tends to fail in its own way. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. If you’re worried about failed upstands where the roof meets a wall and leaks around rooflights, a survey will tell you what’s going on, on EPDM rubber, GRP fibreglass and upstands and outlets alike.
Flat roofs on exposed homes in small places like Lagness take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Flat and commercial roofs around Lagness
Lagness is within about 3 miles of the coast, so there’s more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your house is among the older ones in the streets near Church of St Giles, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For landlords with property near Bognor Regis station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Lagness is about 2 miles west of Bognor Regis, in West Sussex. If you’re in Lagness, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Our West Sussex coverage includes Lagness. You can also see our page for Portsmouth.

Lagness: your questions answered
Is the coastal weather around Lagness hard on roofs?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch.
How do I find out if my home in Lagness is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is a flat roof survey the same as a building survey?
No. It’s a survey of the flat roof. It is not a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. It often sits alongside a buyer’s building survey.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in; we’ll agree the details when you book.
What do I do with the report?
The report arrives by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Can you survey at the weekend?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Can you survey a flat roof on an office or unit?
Yes. Offices, units, shops and blocks of flats are all part of our work. We quote bigger roofs on their size and how they’re reached, so please call 07833 053749 or send us an email with the details.
Landlord and commercial surveys in Lagness
Any of our surveys can be booked by landlords, agents and building managers in Lagness. To discuss a property or a block, ring 07833 053749 or send us an email.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
What we are asked to look at in Lagness
A buyer’s general survey often recommends a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
Common reasons to book include:
- A sagging deck under the covering
- Splits and cracks in the covering
- Blistering in felt or asphalt
- Failed upstands where the roof meets a wall
Take a building like Rose Green Junior School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Roof by roof
Felt and built-up roofs
The edges and upstands of a felt roof are normally where trouble starts. Every upstand and edge is looked at, with photos of any that have lifted or cracked.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.

The survey, step by step
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. For a village or hamlet like Lagness, the journey is planned beforehand: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Preparing for the visit
- Leave side gates unlocked
- If it is not your property yet, arrange access through the agent
- Move anything stored under the loft hatch
How to book
Most bookings start with a short call: ring 07833 053749 or use the contact form. You will have a price before anything is arranged.

When you need someone else
Some things can’t be seen without opening up the roof, so a survey has limits:
- Hidden layers beneath the covering
- An exact number of years the roof has left
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
If you are not sure which survey you need, call 07833 053749 or drop us an email and we will give you a straight answer. The full list of what we check.
Roofs we survey in Lagness
- EPDM rubber
- Mastic asphalt
- GRP fibreglass
- Single-ply membranes
- Upstands and outlets
- Felt flat roofs
Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Check ceilings under the roof for damp patches
- Limit foot traffic on the covering
- Book a survey every few years
- Check that new brackets or units haven’t damaged the covering
Many people send the report to two or three roofers for quotes. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
