Roof leak investigation in Alton
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it is needed. We are often asked to look into water through the ceiling under a flat roof and wet patches high on an inside wall, across slate and tile slopes, valleys and parapet gutters and the roof space.
Strong winds lift loose tiles, slates and ridge pieces in towns like Alton as anywhere. What counts as a storm depends on your policy; many use gusts of around 55 mph. Photographs and a written account help you show what happened, whether to an insurer or a roofer. Policies typically exclude wear and tear, which is why the age of the damage matters.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Can I check my roof myself?
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Common questions in Alton
How should I get ready for a visit in Alton?
It helps to clear access to the loft, and to let us know about leaks, damp patches or recent work. Parking and access details for Alton help us plan the visit.
Do you cover Alton?
Yes, Alton is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Why does not the damp patch line up with the hole?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it shows. Tracing that path is the heart of a leak investigation.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you go up on the roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where applicable let us see the rest, and the report records anything we couldn’t see.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it is useful, and it’s included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Will you photograph what you find?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Clear the loft hatch so we can get in
- Put a bucket under the drip and move valuables
- Leave roof access to professionals
- Mention earlier attempts to fix the leak
Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely. The survey usually takes between one and two hours for most houses; commercial roofs usually need 3–4 hours. In Alton, parking is rarely complicated, though it helps to know about driveways or restrictions. The inspection covers whatever is safely visible from outside, from windows and from the roof space, and from the roof itself where it’s safe.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Before the survey
- Point out any leaks or damp patches
- Clear the way to the loft hatch
- Unlock side gates and any roof access doors
Getting a price
Once you know what you need, call 07833 053749 or email us. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.

When to book a survey in Alton
Flat roofs fail with age and wear. Felt frequently lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks frequently start at the edges, upstands and outlets.
Here are some of the things we see frequently:
- Drips in the loft during heavy rain
- Water that shows only in certain storms
- Leaks below a flat extension roof
- Stains around a skylight
Landlords with a home close to Alton station may find that a tenant living with a leak needs the cause found, not just the stain painted over.
What to check before booking
- How much experience they have with roofs like yours
- Whether the price includes VAT
- Whether you can ask questions once you have the report
- What they will not be able to tell you
What a roof leak investigation looks like in Alton
A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Each of these roof types has its own typical places for water to get in. Historic houses such as Bentworth Hall, about 3.2 miles west, show how far back building in the area around Alton goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
The streets around a church such as Church of St Lawrence are often among the oldest in a place, and if yours is one of the older homes nearby, lead flashings, valleys and old chimneys are typical places for water to get in. Anyone responsible for a site like Saint Lawrence Church of England Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain.
