Flat roof survey in Harlington, Greater London
Flat roof surveys in Harlington from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys across London and South East England.
- Outlets that hold water back
- Damaged trims at the roof edge
- Raised blisters across the surface
How it works
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We check the roof from wherever it can be seen safely.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- The findings are written up with photos and recommendations and emailed to you.
Getting ready for the survey
- Let us know about parking near the property
- For flats, check roof access has been agreed
- Make a note of anything you’d like us to look at
How to book
Photos help, if you have them. Take them safely from ground level or a window, and please don’t climb up for a closer look. To get started, phone 07833 053749 or send us an email.
Advice
Flat roof survey in Harlington
A flat roof leak often travels before it shows on the ceiling. It can run along the deck from a split, an open lap or a failed upstand some distance away. That is why we check every detail across the roof, not only the area above the stain, with photographs of anything that could be letting water in. Whoever carries out the work then has a clear starting point. If you’ve noticed a sagging deck under the covering and pools of water lying on the roof, we can find out what’s behind it, on EPDM rubber, upstands and outlets and mastic asphalt alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Harlington shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

Should I look at the roof myself first?
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.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
How we price flat roof surveys
Prices always include VAT. The things that change the price are:
- Building height and the viewpoints available
- How big the roof is
- Which survey package you book
- Whether thermal imaging or a drone is needed
Prices start from £150, including VAT. The final price depends on how big and how high the roof is, how it can be seen safely and which survey you book.
What we need to know
You do not need to know any roofing terms. Just let us know:
- When you need the report by
- Where water is showing inside, if it is
- Access details, such as a loft hatch or a shared roof
- Why you want a survey: buying, a leak, a storm or new work
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or send us an email.
What we can’t see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Fragile surfaces, which we do not walk on
- Whether old sheeting or boards contain asbestos
- Hidden layers beneath the covering
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we’ll tell you before you book. What a survey covers and doesn’t.

For landlords and managing agents
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Where a roof is shared: we need access agreed with the building owner or managing agent. Tell us about it when you book and we’ll plan the visit with that in mind.
Questions from Harlington
Does a conservation area affect roof work in Harlington?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can parking be tricky for a visit in Harlington?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Do you cover flat roofs on blocks of flats?
Yes. Commercial and residential flat roofs are both covered. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
What insurance do you have?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Does the survey cover asbestos?
Our survey does not include asbestos testing. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
How long will you be at the property?
Most surveys take about 1–2 hours at a typical home, and more on a big or complicated roof. We’ll confirm the timing when booking.
What we are asked to look at in Harlington
No flat roof covering lasts for ever. Felt roofs often last around 15 to 20 years, EPDM often 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
Look out for signs like these:
- Leaks around rooflights
- Loose or cracked edge trims
- Failed upstands where the roof meets a wall
- Blocked or damaged outlets
If you own one of the older houses in the streets near Church of St Peter and St Paul, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before booking any roof surveyor
- What insurance they carry
- Whether the loft is part of the inspection
- How much experience they have with roofs like yours
- Their report turnaround times
Flat and commercial roofs around Harlington
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Osterley House, about 3.6 miles east, is one of the historic houses in the wider area around Harlington. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If you look after a shop, office or commercial unit, for example near Treaty Centre, a flat roof over a business is out of sight and out of mind until it leaks. Hotels and guest houses near Harlington cannot easily close rooms for a leak.
