Common questions in Aston
Will you come out to Aston?
Yes, Aston is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Should a flat-roofed garage or porch in Aston be checked too?
Often, yes, so mention it as you book. Flat-roofed garages and porches are common in new towns like Stevenage, and older felt coverings may be near the end of their life.
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 and can sit alongside a RICS survey.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Do you use low-voltage or high-voltage testing?
The roof decides the method. We will explain why when we quote.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or drop us an email for a quote.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch.
Electronic leak detection for homes and businesses in Aston
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. If you are worried about breaches hidden under paving or planting and leaking laps in the waterproofing, we can find out what’s behind it, on green roofs, single-ply roofs and flat roof membranes alike.
Older buildings in small places like Aston 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.
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 is not.

What you can safely check yourself
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking.
What happens on the day
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Aston can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- If it isn’t your property yet, arrange access through the agent
- Let us know where we can park nearby
- Dig out any old roof reports or invoices
How to book
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To send them or to book, ring 07833 053749 or drop us an email.
Related advice
What we’re asked to look at in Aston
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Most people get in touch after spotting one of these:
- Leaks through a covered membrane
- Failed seams and laps
- Punctures from foot traffic or tools
- Repairs that haven’t stopped the leak
The streets around a church such as Parish Church of St Mary the Virgin 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.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- Their insurance cover
- What the report includes, and whether it has photos
- Whether VAT is added on top
Useful tips for Aston property owners
These tips come from what we see on roofs every week:
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
- Avoid repeated repairs without finding the cause
- Check new waterproofing before handover
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.

Why it is worth a survey now in Aston
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Older cottages and farmhouses around Aston can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

Electronic leak detection around Aston
With Aston Bury about 0.7 miles south, Aston sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Stevenage, which Aston is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
For site and facilities teams at buildings such as Aston St Mary's Church of England Aided Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Knebworth station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
