Colworth Flat Roof Survey
Find out what’s going on with the flat roof before you spend money on it. We carry out flat roof surveys in Colworth.
- Splits, cracks and crazing
- Damaged trims at the roof edge
- Pools of water lying on the roof
What we do, step by step
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. A typical survey takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Older rural homes like those around Colworth can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We check the roof from the ground, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Before we arrive
- Check the loft hatch can be reached
- For a flat or shared roof, check access with the building owner or managing agent
- Show us where any leaks or stains appear

How a flat roof survey works in Colworth
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. If you’ve noticed water getting in at rooflights and failed upstands where the roof meets a wall, we can find out what’s behind it, whatever the roof.
In a small place like Colworth, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

What happens if roof problems are left?
If you’re buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. A report gives you facts to put to the seller or agent. In a place like Colworth, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

Common questions in Colworth
Is the coastal weather around Colworth hard on roofs?
It can do. Within about 3 miles of the sea, as Colworth is, metal fixings wear faster and gales find any loose ridge or slate.
Does a conservation area affect roof work in Colworth?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you look for flat roof leaks?
The survey covers the covering and all the details where leaks usually begin, recording anything that could let water through. Where the source is not obvious, a roof leak investigation or electronic leak detection may be the next step.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Will this cover the whole house?
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. Many buyers use it alongside a building survey.
Do you go up onto the roof?
Only where it’s safe to do so. Otherwise we use windows, vantage points and the spaces below, and the report says if any part couldn’t be seen. Fragile surfaces are never walked on.
How long will you be at the property?
Time on site depends on the roof; most visits take between one and two hours for most houses, and about three to four hours for a commercial roof. The report is sent afterwards by email.
Flat roofs in Colworth
Colworth is within about 3 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. With Goodwood House about 4 miles north-west, Colworth sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Landlords with a home close to Bognor Regis station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings like Bartons Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
