How electronic leak detection works in St Lawrence
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs are not part of the report, so your roofer prices the work. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. We survey green roofs, commercial flat roofs and single-ply roofs, and the problems we are asked to look at most are stains far from any visible defect and leaks at pipes, outlets or fixings.
Some older homes in villages like St Lawrence are listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report works through the roof section by section, from the coverings down to the gutters. You will see the good as well as the bad.

Do you need electronic leak detection in St Lawrence?
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
People typically book a survey when they’ve noticed something like this:
- Gaps at membrane joints
- Waterproofing to test before it is covered
- Damp inside with no sign on the roof
- Repairs that haven’t stopped the leak
The streets around a church such as St Lawrence's Church are often among the oldest in a place, and if your house is among the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Questions to ask before you book
- Which limits apply to the survey
- Are they insured for the work?
- Whether the inside of the roof is included
- Whether you get a written report with photos
Other services in St Lawrence
How the survey changes by roof type
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Common questions in St Lawrence
Do you look at commercial flat roofs near St Lawrence, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
How do I find out if my home in St Lawrence is listed?
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, and councils can also use Article 4 directions.
What do I do with the report?
You’ll receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Will you walk on the roof?
Only if it’s safe. We inspect what can be seen safely: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
How do I arrange electronic leak detection in St Lawrence?
Simply call 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Is this a RICS survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What we cannot see
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- The extent of water in the insulation
- Build-ups without a suitable layer below
- Water entering through details rather than the membrane
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey before booking. What our survey covers.
Roofs we survey in St Lawrence
- Flat roof membranes
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
Can I check my roof myself?
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. Do not go up yourself.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
The survey, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Somewhere like St Lawrence needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Let us know about parking near the property
- Move anything stored under the loft hatch
- Agree roof access with the managing agent if it’s shared
Booking a survey
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or send us an email with the address and the days you’d prefer.

Flat roofs in St Lawrence
St Lawrence is within about 1 mile of the coast, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. St Lawrence has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Rylstone Manor lies about 3.8 miles north-east, so building around St Lawrence goes back a long way. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once. Take a building like St Francis Catholic and Church of England Primary Academy: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Get leaks traced quickly
- Check trades protect the waterproofing
- Do not let outlets block
- Have roof specifications to hand
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
