Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to.
What happens after the survey?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.

The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Electronic leak detection in St John Street area
Our ELD report shows where each breach was found with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a report with photographs. Typical surveys look at punctures from foot traffic or tools and leaking laps in the waterproofing, on green roofs, single-ply roofs and commercial flat roofs.
Around a smaller place like St John Street area, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it. Ponding, splits and lifting edges are the signs to look for from a window.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

How the survey works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a survey in St John Street area, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. Tell us about any garages, outbuildings or extensions you want included.
- We agree the area to be tested.
