How a roof leak investigation works in Liss
The aim is to find where the water is getting in and explain it. You get a report with photographs showing the likely entry point and the route the water is taking, and recommends what should be done. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. We survey lead flashings, chimney stacks and slate and tile slopes, and common reasons people get in touch are wet patches on loft insulation and damp ceilings under a flat roof.
Chimney stacks on older houses around places like Liss can let water in, through worn flaunching, failed pointing or lifted flashings. Damp in a chimney breast can have more than one cause, so it isn’t always obvious where it starts. The stack, its flashings and the loft space beside it are all worth checking.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Practical tips
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Let us know if there are tanks or pipes in the loft
- Clear the loft hatch so we can get in
- Photograph the stain each time it appears
- Let us know about any past repairs to the roof
Your report arrives by email, with photographs of what we found. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
Signs you need a roof leak investigation in Liss
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. The damp may appear on a chimney breast, a ceiling or in the loft.
A survey makes sense if you’ve noticed:
- Damp walls below an overflowing gutter
- Leaks below a flat extension roof
- Damp on a chimney breast
- Drips from nail tips in a cold loft
For site and facilities teams at buildings such as Liss Infant School, tracing a leak on a big roof starts with where the water appears and works back.

What happens on the day
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes roughly 1–2 hours for most houses, and about three to four hours for a commercial roof. You are welcome to ask questions while we are there. A visit to Liss is planned like any other: the time, the access and where to park are agreed ahead of time. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
How to prepare
- Point out any leaks or damp patches
- Keep pets in another room
- Leave side gates unlocked

Different roofs, different checks
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.
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.
Questions from Liss
Do you carry out roof surveys in Liss?
We do. The survey and report are the same in Liss as anywhere else.
Is my home in Liss listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Could my leak actually be condensation?
It’s a common question. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. The report explains which it looks like and what to do.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
What’s in the report?
Written findings with photos, explaining the condition of the leaking roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. We will recommend an engineer if we see signs that call for one.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Landlords, agents and block managers in Liss
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 with budgets and planning.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Why get it checked now?
Lingering damp encourages mould on ceilings and walls. It is unpleasant, and it’s harder to deal with once established. Stopping the water is the first step. On a bungalow or cottage around Liss, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.
Why book with us
- 98% customer satisfaction
- Independent findings on the roof’s condition
- Drone flown under a CAA Flyer ID and Operator ID

Liss roofs and the weather
Some Hampshire villages still have thatched roofs. 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. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
For landlords with property near Liss station, tracing a leak quickly matters when a tenant is living with it. For an older house near a landmark like Church of St Mary, lead flashings, valleys and old chimneys are typical places for water to get in.
