Questions from Astrope

Will you come out to Astrope?

Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.

Is my home in Astrope listed or in a conservation area?

Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.

Does the weather affect the survey?

A survey can typically go ahead in light rain. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.

Do I have to be there for the survey?

If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.

Is it a structural engineer’s report?

No. We are experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.

Do you use low-voltage or high-voltage testing?

The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.

How do I arrange electronic leak detection in Astrope?

To arrange a survey, phone 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.

Electronic leak detection in Astrope

Our ELD report shows where each breach was found with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report; that’s for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. If you are worried about patched roofs that still leak and breaches hidden under paving or planting, a survey will tell you what’s going on, whatever the roof.

In a small place like Astrope, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.

If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

What electronic leak detection looks like in Astrope

About 4.8 miles north lies Ascott House, a reminder of how long the area around Astrope has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.

Anyone responsible for a site like Long Marston VA Church of England Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Cheddington station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Astrope is about 5 miles east of Aylesbury, in Hertfordshire. We provide electronic leak detection for householders, landlords and businesses in Astrope and nearby.

Do you need electronic leak detection in Astrope?

Holes in a membrane often come from feet, tools or debris. Some are too small to see, but still let water through.

Problems we come across often include:

  • Holes left by work on the roof
  • Leaks that return after repairs
  • Leaking laps in the waterproofing
  • Water coming in under a flat roof

For an older house near a landmark such as Church of St Mary (Church of England), flat-roofed rear additions and dormers added over the years are worth checking.

Questions to ask before you book

  • Their drone registration, if they fly one
  • Their insurance cover
  • What happens after the report arrives
  • How long the report takes to arrive

What to expect from a roof survey

What affects the cost of electronic leak detection

The price reflects the time and kit the roof needs. That comes down to:

  • Commercial roofs and larger buildings
  • Extensions, dormers and garages with roofs of their own
  • Height and safe access
  • Roof area

Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Getting in touch

We’ll usually ask about:

  • What made you get in touch
  • The property’s address and postcode
  • How the loft is reached, if there is one
  • Any marks or damp showing indoors

If you are buying, it’s useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

The survey, step by step

Every roof is different; as a rough guide, the survey takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. You are welcome to ask questions while we’re there. Cottages and farmhouses around Astrope often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.

  1. First, we confirm which roof areas are included.
  2. We get the roof ready for testing.
  3. We work across the roof with the test equipment.
  4. We mark the breach locations in our records.
  5. You receive the results to pass to your roofer.

Before the survey

  • Jot down any questions you want answered
  • For flats, make sure roof access has been agreed
  • Check the loft hatch can be reached

Advice

For landlords and managing agents

We survey roofs for landlords and letting agents as well as householders. A report with photographs gives you a clear record of the flat roof membrane, useful for planning maintenance.

Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.

What we look for on each type of roof

Bituminous membranes

Bituminous roofs frequently have laps and old repairs where breaches occur. We test where the roof suits it.

EPDM rubber roofs

ELD on EPDM depends on the product and the layers. We check before we quote.

What happens if roof problems are left?

Some breaches are too small to see. ELD picks up breaches a visual check might miss where the roof suits it. Older and listed buildings around Astrope may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.

The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
