How a roof leak investigation works in Bagmore
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. Even on a dry day, a leak normally leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. We survey lead flashings, valleys and parapet gutters and rooflights and dormers, and common reasons people get in touch are damp ceilings under a flat roof and damp patches next to the stack.
For a small place like Bagmore, the inspection is the same as anywhere: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. If you have photos of the water coming in, they help as well.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

What we look for on each type of roof
Parapet and box gutters
A butterfly roof drains to a central valley gutter. If that gutter or its outlet fails, water can come through the top-floor ceiling.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
How we price roof leak investigations
We confirm the price for your survey before you book. This is what makes a difference:
- Whether you choose the Basic, Standard or Premium Survey
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
- How big the roof is
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £150, including VAT.
Booking your survey
Before you get in touch, it helps to have:
- What made you get in touch
- The kind of building and roof involved
- Any marks or damp showing indoors
- Pictures from the garden or a window, if you have them
A quick phone call is usually the easiest start: ring 07833 053749 or send us an email. The price is agreed before a date is set.
How the survey works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take about one to two hours at most homes, rising to roughly 3–4 hours on a commercial building. Older roofs in small places like Bagmore can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Outside, we look at every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- We email a report with photos, the likely entry point and recommendations.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Jot down any questions you want answered
- Point out any leaks or damp patches

- Leaks from plumbing, tanks or pipework rather than the roof
- Carrying out the fix

Bagmore: your questions answered
Do you cover smaller places like Bagmore?
Yes, Bagmore is on our map. A small place gets exactly the same survey as a big one.
Do you cover Bagmore?
Yes, Bagmore is within the area we cover. We cover the whole of London and South East England. Just call 07833 053749 or use the contact form and let us know about the property.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s included in our Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Will you check the loft?
Usually, if there is one and it can be reached safely. The loft space can show things the outside cannot, like damp timbers, staining or daylight.
Why is the stain in a different place from the leak?
Because water travels. It runs along rafters, battens or underlay before it drips, so the stain may be some distance from where it gets in. We follow the route back instead of guessing.
How do you tell a leak from condensation?
It’s a common question. A leak typically shows in one area and follows rain, while condensation is often spread out and worse in cold weather. The report explains which it looks like and what to do.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we’ll plan the survey around it.
Landlord and commercial surveys in Bagmore
Where a roof is shared: we need access agreed with the freeholder or managing agent. Let us know about it when booking and we will plan the visit with that in mind.
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey seven days a week, which helps when tenants work during the week.
Roof leak investigations around Bagmore
Historic houses such as Hall Place, about 3 miles south, show how far back building in the area around Bagmore goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. 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.
If you let a flat or house near Alton station, a tenant living with a leak needs the cause found, not just the stain painted over. If you live in an older home near Church of St. Mary, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

Can I check my roof myself?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
