Flat roofs in Batford
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Childwickbury Manor about 2.9 miles south, Batford sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
If you let a flat or house near Harpenden station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If your home is one of the older ones in the streets near All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Electronic leak detection for homes and businesses in Batford
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. If you’ve noticed leaks under green or ballasted roofs and waterproofing to test before it’s covered, we can find out what’s behind it, whatever the roof.
Around Batford, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when you book. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

For landlords and managing agents
We survey roofs for landlords and agents as well as householders. A written report with photos gives you a clear record of the flat roof membrane, useful for planning maintenance.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. You are welcome to ask questions while we’re there. For a survey in Batford, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- For flats, make sure roof access has been agreed

Checking the roof from ground level
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
Common roof problems in Batford
Holes in a membrane often come from feet, tools or debris. Some are too small to see, but still let water through.
Most people get in touch when they’ve noticed one of these:
- Damage from equipment installers
- Leaks through a covered membrane
- Leaks through a flat roof with no obvious cause
- Holes around roof penetrations
Take a building like Crabtree Infants' School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
What to check before booking
- Is there a chance to talk the report through?
- Whether you get a written report with photos
- Whether any drone flown is registered with the CAA
- How long the report takes to arrive
Roof by roof
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will tell you if yours is not suitable.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
What a survey costs
A few things affect what a survey costs:
- How many separate roofs there are, such as extensions, dormers and garages
- Roof area
- Whether thermal imaging or a drone is needed
- House, block, shop or office
What a survey costs comes down to the roof itself: 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.
Helping us price your survey
Before you get in touch, it helps to have:
- Any photos you have, taken from ground level or a window
- Any deadline, such as an exchange date
- The type of building and roof, like pitched or flat
- Where water is showing inside, if it is
A quick phone call is usually the easiest start: phone 07833 053749 or email us and we’ll ask a few questions about the roof. You will have a price before anything is arranged.
FAQs for Batford
Does a conservation area affect roof work in Batford?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you cover Batford?
Yes, Batford is one of the places we work. The survey and report are the same in Batford as anywhere else, and visits run on weekdays and weekends.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access as you book.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning. Mention it when you contact us and we’ll plan the survey around it.
How is ELD priced?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks. Just call 07833 053749 or email us for a quote.
