Roof leak investigation in Blackmoor, Hampshire
We take a careful look at the leaking roof at your property in Blackmoor, with photographs and a written report.
- Water coming in around a roof light or dormer
- Ceiling stains that grow after rain
- Water that shows only in certain storms
How a roof leak investigation works in Blackmoor
Flat roofs leak in their own ways. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Ponding water makes any weakness worse. We check the roof surface and the ceiling below to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. If you are worried about water coming in around a roof light or dormer and staining where a gutter or parapet meets the wall, we can find out what’s behind it, on rooflights and dormers, the roof space and lead flashings alike.
Somewhere as small as Blackmoor, older roofs have often been repaired many times. That makes it hard to tell new damage from old wear, which matters if you’re thinking of an insurance claim. We look at what can safely be seen and set out what we find. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. You’ll see the good as well as the bad.

Your questions about roof leak investigations in Blackmoor
Do you carry out roof surveys in Blackmoor?
We do. The survey and report are the same in Blackmoor as anywhere else.
How do I find out if my home in Blackmoor is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
What insurance do you have?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Will you go up on the roof?
Only where it is safe to do so. We check everything that can be seen safely: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Why is the stain in a different place from the leak?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it finds a way through the ceiling. Following that route is what our investigation does.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
Can a leak be traced on a dry day?
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.
Signs you need a roof leak investigation in Blackmoor
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
Typical things we’re asked to look at include:
- Damp ceilings under a flat roof
- Damp underlay across a wide area
- Damp patches next to the stack
- Water marks that spread in wet weather
For an older house near a landmark such as St Matthew's Church, lead flashings, valleys and old chimneys are typical places for water to get in.
Questions to ask before booking
- Whether you get a written report with photos
- Are they insured for the work?
- What’s outside the scope of the survey
- Their report turnaround times
Leaks and storm damage in Blackmoor
Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East frequently 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. 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.
Anyone responsible for a site like St Matthew's Church of England Aided Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. If you let a flat or house near Liss station, a tenant living with a leak needs the cause found, not just the stain painted over.

What we cannot see
A survey is a close look at the leaking roof, but it can’t do everything. The main limits are:
- What’s under the covering or behind the plaster
- A promise to find every leak on a single visit
- Whether rotten timbers meet design loads
If in doubt, call 07833 053749 or use the contact form and we will recommend the right survey. What a survey covers and doesn’t.

What else we do in Blackmoor
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Clear the loft hatch so we can get in
- Let us know about any past repairs to the roof
- Put a bucket under the drip and move valuables
- Don’t climb onto the roof to look
Once the work is done, hold on to the report. If water appears again, it shows what was found before.
Keep the loft space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation doesn’t block airflow at the eaves.
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
What we look for on each type of roof
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from every safe vantage point.
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take between one and two hours, more where the leak is intermittent or the roof is large. In a small place like Blackmoor, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are checked, 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 it is not your property yet, arrange access through the agent
- Gather any invoices or paperwork from past roof work
- If the roof is shared, arrange access with whoever manages the building
