How the survey works
Safety comes first on every visit. We inspect whatever is safely visible, and anything we can’t see is noted in the report. Most visits take a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. For a village or hamlet like Gomshall, the journey is planned ahead of time: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Preparing for the visit
- Clear the way to the loft hatch
- For flats, make sure roof access has been agreed
- Tell us about parking before the day
Getting a price
Every survey is priced before it’s booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or use the contact form.
Advice
Electronic leak detection for homes and businesses in Gomshall
A leak in a flat roof frequently shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey green roofs, liquid-applied waterproofing and single-ply roofs, and people most often book us about new membranes needing a check before handover and leaks at pipes, outlets or fixings.
Older buildings in small places like Gomshall may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. 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.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

FAQs for Gomshall
Does a conservation area affect roof work in Gomshall?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover Gomshall?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How long will testing take?
It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too.
What happens next?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Do you need to get into the loft?
Normally, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that cannot be seen from outside.
What’s the best way to book?
To book, call 07833 053749 or send us an email and tell us the address and what you want to find out. We will confirm the price and agree a day with you.
Signs you need electronic leak detection in Gomshall
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
Look out for signs like these:
- Waterproofing to test before it’s covered
- Leaks through a covered membrane
- Damage from equipment installers
- Stains far from any visible defect
Landlords with a home close to Gomshall station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Choosing a roof surveyor
- Whether the price includes VAT
- Which parts of the roof they’ll actually see
- What the report includes, and whether it has photos
- How soon the report will arrive
What we look for on each type of roof
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We’ll tell you if yours isn’t suitable.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Areas we can’t reach or that can’t be tested
- Repairing the breaches (that is for your roofer)
- Roofs whose membrane or build-up isn’t suitable
Not sure which survey suits your roof? You can phone 07833 053749 or use the contact form and we’ll tell you before booking. The full list of what we check.

Useful tips for Gomshall property owners
A survey works best with a little help from you, before and after. Some tips:
- Check trades protect the waterproofing
- Keep outlets clear of debris
- Find the breach before more patching
- Note where leaks show inside and when
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Checking the roof from the ground
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Flat and commercial roofs around Gomshall
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Hatchlands Park, about 2.9 miles north, show how far back building in the area around Gomshall goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church such as The Church of St James are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Take a building like Shere CofE Aided Infant School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
