Common questions in Great Dunmow
Do you cover smaller places like Great Dunmow?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Do you cover commercial flat roofs around Great Dunmow?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.

No. We point out what can be seen, like sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
About our electronic leak detection in Great Dunmow
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Tell us about your roof to find out more. We survey green roofs, flat roof membranes and commercial flat roofs, and the problems we’re asked to look at most are leaks under green or ballasted roofs and new roofs to check before paving or planting.
Around a smaller place like Great Dunmow, flat roofs normally cover extensions, garages and dormers. Even a small flat roof can let plenty of water into the room below. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen. The survey normally takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. For a survey in Great Dunmow, 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.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Point out any leaks or damp patches
- Have keys ready for side gates, garages or roof access doors
- Jot down any questions you want answered

Advice
Common roof problems in Great Dunmow
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs though it depends on the layers.
Look out for signs like these:
- Leaks at pipes, outlets or fixings
- Leaking laps in the waterproofing
- Waterproofing to test before it is covered
- Holes left by work on the roof
If you let a flat or house near Stansted Airport station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
What to check before booking
- What exactly goes into their report
- How long the report takes to arrive
- Are they insured for the work?
- Whether the loft is part of the inspection
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Blocked gutters on homes around Great Dunmow overflow and soak walls, particularly where trees overhang. Dealing with the cause is simple; drying out a wall is not.

What we look for on each type of roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Electronic leak detection around Great Dunmow
What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned. In Essex, older buildings are frequently clay-tiled, many with weatherboarding, while many towns grew with post-war and newer estates. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Parish Church of St Mary the Virgin: the flat roofs on later extensions tend to wear out long before the main roof. A roof leak in a hotel or guest house around Great Dunmow means lost rooms as well as repairs, so it is worth knowing the roof’s condition.

What a survey costs
A few things affect what a survey costs:
- Building height and the viewpoints available
- The size of the roof
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

A little information up front helps. Please include:
- Where any leaks, stains or damp patches show inside
