Questions from Appspond
Do you carry out roof surveys in Appspond?
Yes. Our area covers London and South East England, and Appspond is part of that. You can phone 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Appspond?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Electronic leak detection in Appspond
Our ELD report shows where each breach was found, with photos. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you’ve noticed holes around roof penetrations and patched roofs that still leak, we can find out what’s behind it, on roof terraces and balconies, green roofs and single-ply roofs alike.
Somewhere as small as Appspond, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

How the survey works
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes a time that depends on the membrane area and the build-up, which we set out in the quote. Somewhere as small as Appspond, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Check the loft hatch can be reached
- Jot down any questions you want answered
- Show us where any leaks or stains appear
How to book
To book a survey, call 07833 053749 or email us with the address and what you’d like to know about the roof. We will confirm the price before booking.
Advice
Do you need electronic leak detection in Appspond?
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in for months before it shows.
These are some of the problems a survey can pick up:
- Damage from equipment installers
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
- Leaks that return after repairs
Shop and office owners around Village Arcade St Albans may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Questions to ask before you book
- Their insurance cover
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What they will not be able to tell you
- Which parts of the roof they’ll actually see
Practical tips
Most of what helps is simple and safe from ground level. A few suggestions:
- Keep foot traffic on flat roofs to a minimum
- Share any drawings of the roof
- Don’t let outlets block
- Do not keep patching the same spot
Questions about the results are welcome. We can talk you through the findings.
Check contractors protect the waterproofing when fitting equipment. Have the roof looked at after other work.
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
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.

Flat and commercial roofs around Appspond
Historic houses like High Elms Manor, about 2.5 miles south, show how far back building in the area around Appspond goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For landlords with property near St Albans Abbey station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Take a building like Marlborough Science Academy: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
