Common questions in The Wrythe
Will parking be an issue for a roof survey in The Wrythe?
Sometimes, yes. If The Wrythe has controlled parking where you are, a visitor permit is the easiest answer.
How do I find out if my home in The Wrythe is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
What happens next?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To arrange a date, phone 07833 053749 or send us an email.
Do you work in The Wrythe?
Yes. We survey roofs across London and South East England, and that includes The Wrythe.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when you book.
About our electronic leak detection in The Wrythe
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We’ll say if ELD won’t work on your roof at the start. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that can’t give results. If you’ve noticed patched roofs that still leak and leaks under green or ballasted roofs, we can find out what’s behind it, on green roofs, commercial flat roofs and flat roof membranes alike.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in The Wrythe, access is agreed with whoever manages the roof before the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Tips that help
Here are a few things we’d tell any owner:
- Let us know about the membrane and build-up if you know it
- Ask contractors to protect the membrane
- Avoid repeated repairs without finding the cause
- Do not let outlets block
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Honest limits
To be straight with you, there are limits to any roof survey:
- Fixing the holes we find
- Leaks from plumbing or windows
- Moisture spread under the membrane

Electronic leak detection in The Wrythe: local notes
With Nonsuch Mansion about 2.9 miles west, The Wrythe sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
Take a building like Victor Seymour Infants' School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. For landlords with property near Carshalton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For an older house near a landmark like Bishop Andrewes Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
The Wrythe is about 7 miles south of Stockwell, in Greater London. We visit The Wrythe as part of our work across Greater London, for homes and businesses alike. We cover towns and villages across Greater London. London is in our area too.

Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
How the survey changes by roof type
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
How it works
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in The Wrythe runs like any other.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked
- Keep pets inside or away from the areas we are looking at
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or send us an email when you are ready.
