Flat Roof Survey in High Leigh
Surveys of flat roofs on homes, extensions and commercial buildings across High Leigh, with drones and thermal imaging where they help. Call or email for a price.
- Pools of water lying on the roof
- Cracked or split membrane
- Raised blisters across the surface
When to book a survey in High Leigh
Flat roofs frequently get walked on for other jobs: to clean windows, fit aerials or air conditioning units, or reach a gutter. Each visit can damage a covering not made for regular foot traffic. New brackets and fixings through the roof are another common source of leaks.
Problems we come across often include:
- Dips that suggest the deck is deflecting
- Gaps at upstands and abutments
- Standing water left after rain
- Cracked or split membrane
Anyone responsible for a site like Westfield Community Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- Whether VAT is added on top
- Is there a chance to talk the report through?
- Which viewpoints they use to see the roof
- What exactly goes into their report
How a flat roof survey works in High Leigh
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. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. Common reasons to book are raised blisters across the surface and splits and cracks in the covering, on GRP fibreglass, single-ply membranes and mastic asphalt.
In a small place like High Leigh, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

DIY checks: what’s safe
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
What happens on the day
We do not take risks to get a closer look. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. The survey typically takes roughly 1–2 hours for most houses, and about three to four hours for a commercial roof. Rural addresses near High Leigh can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Before the survey
- Tell us where we can park nearby
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work

Advice
Questions from High Leigh
Does a conservation area affect roof work in High Leigh?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you cover High Leigh?
We do. Every survey there gets the same written report with photographs.
Should I worry about standing water on my flat roof?
Water that lies on a flat roof for days is a sign that something needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
Will I get photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
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.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we’ll talk to you about another date.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
Roof by roof
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. Every upstand and edge is looked at, with photos of any that have lifted or cracked.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We check for splits, gaps and loose flashings above the upstand.
Honest limits
Before booking, it’s worth knowing what a survey will not do:
- Whether the deck or joists are strong enough
- Hidden layers beneath the covering
- Asbestos testing, which needs a specialist asbestos surveyor
If in doubt, call 07833 053749 or drop us an email and we’ll point you to the right survey before you book. The full list of what we check.

What else we do in High Leigh
Local flat roofs in High Leigh
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing.
Take an older house close to Church of St Catherine & St Paul: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Broxbourne station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
