About our roof leak investigation in Longstock
Older homes have more places for water to get in. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. We check parapets, valleys and flashings from every safe viewpoint. The findings are recorded with photos. Common reasons to book are staining around the chimney inside and condensation that looks like a leak, on rooflights and dormers, lead flashings and flat roof details.
Roofs in small places like Longstock often stand in the open, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A record with photos is useful if you need to show the damage to anyone else.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What happens if roof problems are left?
A leak that returns after a repair typically means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. In a small place like Longstock, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.

Tips that help
From years of surveys, a few habits stand out:
- Check whether pipes or tanks run near the stain
- Protect furniture and flooring under the leak
- Clear the loft hatch so we can get in
- Do not touch fittings that water is reaching
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
What a roof leak investigation looks like in Longstock
Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Different coverings let water in at different points, which shapes where the search starts. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
If you look after a building such as Test Valley School, on a building that size, finding the source of a drip means looking well beyond the stain. For hotels and guest houses around Longstock, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. For an older house near a landmark such as Church of St Mary, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Questions from Longstock
Do you cover Longstock?

Do you cover smaller places like Longstock?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
How do I book a survey in Longstock?
Simply ring 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. The report gives any roofer a clear brief.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, tell us as you book.
Will you walk on the roof?
Not unless it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed.
For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps when budgeting.
Businesses and commercial landlords can book us too. Bigger roofs take more time, and they’re priced for the size.
What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take between one and two hours for most homes, though a hard-to-trace leak can take longer. In a hamlet or village like Longstock, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- You let us know where the water shows and when it appears.
- 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.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
How to prepare
- If you’re buying, let the agent know when we are coming
- Dig out any old roof reports or invoices
- Jot down any questions you want answered
Getting a price
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or email us with the details.
Advice
Checking the roof from the ground
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
How the survey changes by roof type
Lead flashings
Mortar fillets are sometimes used instead of lead. Fillets crack and pull away over time, letting rain run behind the joint.
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. One slipped slate can be enough to cause a leak, particularly in driving rain.
