Flat roof surveys for homes and businesses in Croxley Green
Standing water is one of the first things we look for on a flat roof. It can point to poor falls, a blocked outlet or a deck that is deflecting. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’ve noticed failed upstands where the roof meets a wall and water getting in at rooflights, we can find out what’s behind it.
Flat roofs on exposed homes in small places like Croxley Green take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently 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 typically the first part of a flat roof to go.
Where we cannot see part of the flat roof, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Croxley Green questions
Does a conservation area affect roof work in Croxley Green?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Croxley Green within the area you cover?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Will you walk on the flat roof?
Where it’s safe, the roof is inspected from the roof itself. Otherwise we use windows, vantage points and the spaces below, and we note any area we couldn’t see. Fragile surfaces are never walked on.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
How long is the visit?
Most surveys take between one and two hours on an ordinary house, though large, tall or awkward roofs take more time. We will confirm the timing when booking.
Do you look in the loft space?
If there is a loft and safe access to it, yes. The roof space can show things the outside can’t, such as damp timbers, staining or daylight.
Does a flat roof survey replace a RICS survey?
No. We look closely at the flat roof rather than the whole building. It works alongside a RICS home survey, not instead of one, and structural calculations need a structural engineer.
Flat roofs in Croxley Green
With Chenies Manor House about 4.2 miles north-west, Croxley Green 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, and a listed home or one in a conservation area may need consent for changes of material. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For an older house near a landmark such as St Oswald's Parish Church, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Rickmansworth station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building such as Harvey Road Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Croxley Green is about 1 mile north-east of Rickmansworth, in Hertfordshire. We provide flat roof surveys for homes and businesses in Croxley Green and the surrounding area. Our area takes in places right across Hertfordshire. For surveys nearby, see our London page.

The survey, step by step
The visit usually starts outside and finishes in the loft: outside views come first, then the roof space if there’s safe access. In total, it takes about 1–2 hours for a house, though large, tall or awkward roofs take more time. Older roofs in small places like Croxley Green can have low, tight loft spaces, so it is useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking 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.
Before the survey
- Move anything stored under the loft hatch
- If you are buying, check with the agent that we can get in
- If the roof is shared, arrange access with whoever manages the building

What affects the cost of flat roof surveys
A few things affect what a survey costs:
- Whether it’s a home or a commercial building
- How big the roof is
- The number of roofs, including extensions and garages
- Whether thermal imaging or a drone is needed
Prices quoted always include VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Helping us price your survey
If you can, have these to hand when you contact us:
- Where water is showing inside, if it is
- Access details, such as a loft hatch or a shared roof
- When you need the report by
- The reason for the survey, such as buying, a leak or storm damage
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or drop us an email.
Should I look at the roof myself first?
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.

Practical tips
Getting the most from a flat roof survey starts before we arrive and carries on afterwards. Some tips:
- Ask contractors to protect the roof if they work on it
- Have the roof looked at again after a severe storm
- Keep outlets clear of leaves and moss
- Check from a window for ponding after heavy rain
If you are buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
What we look for on each type of roof
Rooflights and upstands
Rooflights and fragile sheets are never walked on. They’re inspected from safe positions and recorded with photographs.
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. The survey looks at welded seams, edges, fixings and signs of damage.
