Acton Vale: your questions answered
How do I find out if my home in Acton Vale is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Can parking be tricky for a visit in Acton Vale?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we will work around them.
Can you survey a shared roof?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
How do you choose the testing method?
The roof decides the method. We will explain why when we quote.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How do I book a survey in Acton Vale?
To book, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
About our electronic leak detection in Acton Vale
Some flat roofs cannot be tested electronically. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you at the start. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It saves a wasted visit. We are often asked to look into gaps at membrane joints and holes around roof penetrations, across roof terraces and balconies, liquid-applied waterproofing and flat roof membranes.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Acton Vale shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
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.

Useful tips for Acton Vale property owners
Small things make a difference. Some pointers:
- Share any drawings of the roof
- Do not let outlets block
- Stay off the flat roof unless needed
- Avoid repeated repairs without finding the cause
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
What we are asked to look at in Acton Vale
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs, depending on the build-up.
It is worth booking a survey if you’ve seen:
- Holes around roof penetrations
- Leaks that return after repairs
- Leaks under green or ballasted roofs
- Stains far from any visible defect
The streets around a church such as St Saviour's Centre for the Deaf are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.
Before booking anyone
- Is VAT included in the price?
- Whether you get a written report with photos
- How they plan to inspect the roof safely
- Their insurance cover
How the survey works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photographs as we go and make notes for the report. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear
- Let us know where we can park nearby

Flat and commercial roofs around Acton Vale
Acton Vale has a number of hotels within about a mile and a half. If you look after one, a leak through a flat roof can put a room out of use. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Historic houses such as Emery Walker's House, about 1.2 miles south, show how far back building around Acton Vale goes. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
