Hunsdon roofs and the weather
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. The covering and its details give the first clues when tracing where water is coming from. About 3.6 miles north lies Much Hadham Palace, a reminder of how long the area around Hunsdon has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
The streets around a church such as St Francis Chapel are often among the oldest in a place, and if you own one of the older houses nearby, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks. Take a building like Hunsdon Junior Mixed and Infant School: a leak through a large roof is often found some distance from where the water shows inside.

Roof leak investigation in Hunsdon: what you get
A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot, along with any photos you’ve taken. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. We survey rooflights and dormers, slate and tile slopes and lead flashings, and the problems we’re asked to look at most are water that shows only in certain storms and damp on a chimney breast.
Many homes in small places like Hunsdon face open ground, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

How the survey works
The aim of the visit is simple: to see as much of the leaking roof as can safely be seen and record it clearly. Notes and photos go into the written report. It normally takes about one to two hours for most homes, though a hard-to-trace leak can take longer. In a small place like Hunsdon, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- You receive a written report with photos showing the likely source and what needs attention.
How to prepare
- Dig out any old roof reports or invoices
- Make sure the loft hatch can be reached
- Make sure pets are kept safely away
How to book
If you have photos of the roof, send them over. Take them safely from the ground or a window. To get started, phone 07833 053749 or drop us an email.
Advice
What a roof leak investigation does not cover
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- A structural engineer’s report
- An intermittent leak that shows no trace on the day
- Defects hidden under coverings or inside walls without opening up

Signs you need a roof leak investigation in Hunsdon
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Things that often lead to a survey include:
- A leak that comes and goes with the weather
- Wet patches on loft insulation
- Damp patches next to the stack
- Water marks that spread in wet weather
Landlords with a home close to Roydon station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
It’s useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
What happens if roof problems are left?
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. An investigation now gives you time to plan the work. For older village homes like those around Hunsdon, the right replacement materials aren’t always easy to find quickly. That’s one more reason to find defects before they become urgent.

Hunsdon questions
Do you carry out roof surveys in Hunsdon?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How do I find out if my home in Hunsdon is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you need to get into the loft?
Normally, if there’s one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Can you find a leak when it is not raining?
Often, yes. Leaks leave clues, like staining, damp timber and moisture in materials. Some leaks only show in particular weather, so photos and notes from when it leaks help a lot.
How long does a roof leak investigation take?
It typically takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.
How should I prepare for the leak investigation?
Make sure the loft can be reached. Gather any photos and notes about when it leaks, and tell us about past repairs. Keep catching drips and keep water away from electrics.
Can you always find the source?
We can’t promise to find every leak on one visit. Most leave clues we can follow, but intermittent leaks that need particular weather can be harder. The report sets out what we found and the most likely routes.
How the survey changes by roof type
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is checked from every safe viewpoint.
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. If that gutter or its outlet fails, water can come through the top-floor ceiling.
