Flat and commercial roofs around Agar Town
Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Agar Town is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Winfield House, about 1.5 miles west, show how far back building in the area around Agar Town goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Shop and office owners around Brunswick Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. For landlords with property near Camden Road station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you live in an older home near All Saints, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

Electronic leak detection in Agar Town
We carry out electronic leak detection on flat roofs in Agar Town and across London and South East England. Testing normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a written report with photos. We survey commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing, and people most often book us about stains far from any visible defect and breaches around outlets and penetrations.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Agar Town, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- For flats, make sure roof access has been agreed
- Mention any parking restrictions on your street
- Clear the way to the loft hatch

What else we do in Agar Town
Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Stay off the flat roof unless needed
- Find the breach before more patching
- Have roof specifications to hand
- Use boards when working on the roof
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Act on leaks quickly. Water under a membrane can spread.
What this survey cannot tell you
We only report everything that’s safely in view on the day, so there are some things a survey can’t cover:
- Repairing the breaches (that’s for your roofer)
- Build-ups without a suitable layer below
- How wet the insulation is
If in doubt, ring 07833 053749 or email us and we will suggest the right survey. What our survey covers.

Checking the roof from the ground
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
