About our flat roof survey in Pinner Green
Many commercial buildings and blocks of flats have big flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. The photographed record helps you plan and budget for work. Commercial roofs are quoted for their size and access, so it helps if you ring 07833 053749 or send us an email with the address and a rough idea of the roof area. We survey upstands and outlets, EPDM rubber and single-ply membranes, and the problems we are asked to look at most are outlets that hold water back and failed upstands where the roof meets a wall.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Pinner Green, the roof above may belong to the building rather than one flat.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

When you need someone else
A survey is a proper look at the flat roof, but it cannot do everything. The main limits are:
- Structural calculations, which need a structural engineer
- A fixed date for when the roof will need replacing
- What’s under the membrane without opening it up
If in doubt, phone 07833 053749 or use the contact form and we’ll point you to the right survey before you book. What our survey covers.

Questions from Pinner Green
Is parking a problem for a survey in Pinner Green?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Is my home in Pinner Green listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover Pinner Green?
Yes. Our area covers London and South East England, and that includes Pinner Green.
How much does a flat roof survey cost in Pinner Green?
Our price is from £150, including VAT. You will know the price for the job before booking. To get a price, ring 07833 053749 or drop us an email.
How do you inspect a flat roof?
It depends on what’s safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.

Practical tips
Small things make a difference. Some pointers:
- Keep outlets clear of leaves and moss
- Ask whoever fits equipment on the roof to make good the covering
- Note any new marks on ceilings beneath the roof
- Keep records of when the roof was laid and what work has been done
Buyers can take the findings back to the seller or the agent. It can support a request for work before completion or a conversation about price, depending on the findings.
Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the visit with that in mind.
What we do, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. The survey usually takes between one and two hours for a small flat roof at home, and longer for a large commercial one. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Pinner Green moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from ground level, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
Before we arrive
- Keep pets inside or away from the areas we’re looking at
- Check we can get to the back of the property
- Have any questions written down, so nothing gets missed
Arrange a survey
Getting a price is simple: just phone 07833 053749 or email us and give us some details about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
Flat roof surveys in Pinner Green: local notes
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Headstone Manor about 1.7 miles east, Pinner Green sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Hatch End station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. The streets around a church like Christian Science Church are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems usually start.

Do you need a flat roof survey in Pinner Green?
Water that doesn’t drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Things that frequently lead to a survey include:
- Cracked or split membrane
- Upstands pulling away from walls
- Standing water left after rain
- Blistering in felt or asphalt
For a London address like Pinner Green, it helps to know about controlled parking before the day.
Choosing a roof surveyor
- What happens after the report arrives
- Will they check the loft as well as the outside?
- Their drone registration, if they fly one
- Which limits apply to the survey
Why get it checked now?
Standing water on a flat roof rarely sorts itself out. It usually points to an outlet, the falls or a sagging deck, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
