Egham questions
Is Egham in the area you cover?
Yes, Egham is within the area we cover. Our area covers London and South East England. Just phone 07833 053749 or email us and tell us about the property.
Does a conservation area affect roof work in Egham?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, 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.
How long will testing take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
About our electronic leak detection in Egham
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. Typical surveys look at leaking laps in the waterproofing and leaks showing away from the breach, on flat roof membranes, single-ply roofs and liquid-applied waterproofing.
Around Egham, many garages, porches and extensions have flat roofs of their own. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed. Each kind of covering, from felt to rubber and GRP, is checked in its own way. Asbestos testing is not part of what we do, though a report may flag materials that could contain it.
Findings are set out part by part, from the coverings down to the gutters. You’ll see the good as well as the bad.

What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Practical tips
Nothing here needs a ladder. A few suggestions:
- Act on new leaks promptly
- Clear flat roof outlets regularly
- Avoid repeated repairs without finding the cause
- Share any drawings of the roof
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What happens if roof problems are left?
Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In a family home in Egham, a small roof fault lets water into places you can’t see, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection in Egham: local notes
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 3.7 miles north-west lies Frogmore House, a reminder of how long the area around Egham has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Take an older house close to St John's Church: the flat roofs on later extensions tend to wear out long before the main roof. Take a building like Manorcroft Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

- New membranes needing a check before handover
- Holes around roof penetrations

What else we do in Egham
Landlords, agents and block managers in Egham
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
How the survey works
Every roof is different; as a rough guide, the survey takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. If you have questions on the day, just ask. In Egham, parking is rarely complicated, though it helps to know about driveways or restrictions. The inspection covers everything that’s safely in view from outside, from windows and from the loft space.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Let us know about parking before the day
- Note where any stains or damp appear
- Buyers: confirm access with the estate agent or seller
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.
