What we look for on each type of roof
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped.
Roof leak investigation in Mountnessing
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit. We check parapets, valleys and flashings from every safe vantage point. The findings are recorded with photos. Typical surveys look at ceiling stains that grow after rain and leaks below a flat extension roof, on valleys and parapet gutters, chimney stacks and rooflights and dormers.
Being in a small place like Mountnessing makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Tell us where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

How it works
Once we have finished looking, we write up our findings in a report with photos, sent to you by email. As for time on site, most surveys take about one to two hours for most homes, though a hard-to-trace leak can take longer. Cottages and farmhouses around Mountnessing often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Before we arrive
- Find any records of previous roof work
- Let us know about parking near the property
- Leave side gates unlocked

What we are asked to look at in Mountnessing
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. On slate roofs, slipping is frequently caused by corroded nails.
Things that often lead to a survey include:
- Water coming in around a roof light or dormer
- A leak that comes and goes with the weather
- Staining where a gutter or parapet meets the wall
- Water dripping from rafters or underlay
Living close to Hutton Country Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
Questions to ask before you book
- How they plan to inspect the roof safely
- Whether the loft is part of the inspection
- Their report turnaround times
- Whether VAT is in the quoted price
Practical tips
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Check the loft is accessible
- Let us know what has already been tried
- Tell us if there are tanks or pipes in the loft
- Record whether it leaks in every downpour or only some
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found.
Keep the roof space ventilated. Air movement keeps condensation down, which is often mistaken for a leak. Keep insulation clear of the eaves.

Common questions in Mountnessing
Do you carry out roof surveys in Mountnessing?
We do. Every survey there gets the same written report with photos.
Do you cover smaller places like Mountnessing?
Yes. Mountnessing is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
Can you find a leak when it isn’t raining?
In many cases, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Mountnessing roofs and the weather
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. The covering and its details give the first clues when tracing where water is coming from. The wider area around Mountnessing has a long history of building, with Ingatestone Hall about 1.6 miles east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you own a rental within reach of Ingatestone station, a tenant living with a leak needs the cause found, not just the stain painted over. If you look after a building such as Mountnessing Church of England Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Why it is worth a survey now in Mountnessing
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. Outbuildings and barns around Mountnessing are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
