About our roof leak investigation in Mark Hall South
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We check all of them, from each safe vantage point. If you are worried about damp patches next to the stack and damp walls below an overflowing gutter, we can find out what’s behind it.
Around Mark Hall South, chimneys on older homes are a common source of leaks, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast is not always rain from above, which is why it’s worth tracing properly. It’s worth looking at the stack from outside and at the timbers beside it in the loft.
It is not only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Parking around Mark Hall South is typically easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- Move anything stored under the loft hatch

Mark Hall South questions
Should a flat-roofed garage or porch in Mark Hall South be checked too?
Yes, if you’d like it included, mention it as you book. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Is Mark Hall South within the area you cover?
Yes. Mark Hall South is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Why doesn’t the damp patch line up with the hole?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is often well away from the mark. That’s why we trace the route rather than patching above the stain.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Can you trace a leak in dry weather?
In most cases, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Leaks and storm damage in Mark Hall South
Mark Hall South is part of Harlow, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Take an older house close to St Andrew's Methodist Church: water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you own a rental within reach of Harlow Town station, a tenant living with a leak needs the cause found, not just the stain painted over.

Useful tips for Mark Hall South property owners
From years of surveys, a few habits stand out as worth the effort:
- Catch drips in a bucket and protect the floor
- Write down the wind direction and rain when it leaks
- Tell us if there are tanks or pipes in the loft
- Mention earlier attempts to fix the leak
The report gives whoever carries out the work a clear starting point. The photos show the defects and where they are, so the repair is aimed at the cause.
Look at the roof from ground level after strong winds. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
Signs you need a roof leak investigation in Mark Hall South
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Most people get in touch when they’ve noticed something like this:
- Water coming in around a roof light or dormer
- Water that shows only in certain storms
- Ceiling stains that grow after rain
- Damp ceilings under a flat roof
If you look after a building like Cooks Spinney Primary Academy and Nursery, tracing a leak on a big roof starts with where the water appears and works back.
