Horndean Roof Leak Investigation
Tracing where water is getting into your roof for Horndean and the rest of Hampshire. We survey on any day of the week.
- Damp underlay across a wide area
- Wet patches high on an inside wall
- Water coming in around a roof light or dormer
How a roof leak investigation works in Horndean
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. We survey chimney stacks, valleys and parapet gutters and flat roof details, and the problems we’re asked to look at most are staining where a gutter or parapet meets the wall and damp patches next to the stack.
When a storm passes over a town like Horndean, loose tiles, slates and ridges are the first to move. Many policies treat gusts of about 55 mph as storm conditions, though it varies. A report setting out the damage, with photographs, helps you explain what you’ve found, whether to an insurer or a roofer. Because wear and tear is normally excluded, the age of any damage matters.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What we look for on each type of roof
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. We check every flashing that could feed the stain.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. We check each one as far as we can safely see, and look for damp on the breast inside.
What a roof leak investigation doesn’t cover
Before booking, it’s worth knowing what a survey will not do:
- Faults hidden behind ceilings or boarding
- Plumbing leaks that look like roof leaks
- An intermittent leak that shows no trace on the day

Why get it checked now?
Wet insulation does not insulate well. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. On homes in Horndean, the joint between an extension and the house is where a slow leak tends to start. A few wet winters later, it can mean new plaster and decorating as well as roof work.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.

Questions from Horndean
Do you carry out roof surveys in Horndean?
Yes. Our area covers London and the South East, and Horndean is part of that. Just call 07833 053749 or drop us an email and tell us about the property, and we’ll talk through which survey suits.
Does a conservation area affect roof work in Horndean?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is it a leak or condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We look at the pattern, take moisture readings and tell you which is more likely.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
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.
How quickly is the report sent?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.
Do you use drones?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.

Useful tips for Horndean property owners
Most of what helps is simple and safe from the ground. A few suggestions:
- Move stored items away from the hatch
- Write down the wind direction and rain when it leaks
- Check whether pipes or tanks run near the stain
- Catch drips in a bucket and protect the floor
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
Rented homes, blocks and businesses
Letting agents and landlords in Horndean book surveys as well as homeowners. The report gives you a dated record of the leaking roof, with photos.
An agent can book and manage the survey for a landlord. Access is agreed with the tenant in advance.
Roof leak investigations around Horndean
The coast is about 5 miles or less from Horndean, and places near the sea get more salt in the air and more wind than inland. Strong wind lifts anything already loose, and driving rain gets in wherever it can. About 4.8 miles south-east lies Warblington Castle, a reminder of how long the area around Horndean has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Rowlands Castle station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. The streets around a church such as Saint Wilfrid's are often among the oldest in a place, and if your home is one of the older ones nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in. Take a building like Horndean Technology College: tracing a leak on a big roof starts with where the water appears and works back.

A survey in Horndean needs access inside and out, including the loft hatch and any rooms with damp. Mention gates, side passages and anything at the back. Weekday and weekend visits are available.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
