How a roof leak investigation works in Winchester
Most roof leaks start at a joint rather than the middle of a slope. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We check all of them, from every safe viewpoint. Common reasons to book are staining where a gutter or parapet meets the wall and ceiling stains that grow after rain, on rooflights and dormers, lead flashings and valleys and parapet gutters.
With roofs of every age and type in a place like Winchester, there are many ways for water to get in: slipped slates, cracked tiles, failed flashings, blocked valleys and gutters, or split flat-roof coverings. The stain inside is rarely right under the cause, which is why the inside and outside are looked at together. Moisture readings and a careful look outside help trace where the water has travelled.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

FAQs for Winchester
Do you cover Winchester?
Yes, Winchester is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
Is my home in Winchester listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can thermal imaging help find my roof leak?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
How do I book a survey in Winchester?
Simply ring 07833 053749 or email us. After a few questions, we confirm the price and fix a day.
What should I do before you arrive?
Keep a note of when it leaks. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
Do you use drones?
Yes, where applicable and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
What do I do with the report?
You’ll get the report by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Leaks and storm damage in Winchester
An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent. A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Knowing the roof type helps narrow down where water may be getting in.
Anyone responsible for a site like St Bede 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. For an older house near a landmark such as St Swithun-upon-Kingsgate Church, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Keep a photo record of the damp patch
- Note the weather when the leak shows
- Let us know if there are tanks or pipes in the loft
- Put a bucket under the drip and move valuables
Keep the report after the work is done. If water appears again, it shows what was found before.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.

What else we do in Winchester
What affects the price in Winchester
The price reflects the time and kit the roof needs. The main factors are:
- Whether it is a home or a commercial building
- Building height and the viewpoints available
- How complicated the roof is, with its valleys, chimneys and parapets
- Roof area
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, including VAT. We can help you choose the package that fits what you need to know.
Helping us price your survey
Here’s what helps us most when you get in touch:
- The style of property, from a terrace to a block
- Where water is showing inside, if it is
- Where the property is, with the postcode
- How the loft is reached, if there is one
Every survey is priced before it’s booked, so you know the cost up front. Prices start from £150, including VAT. To book, call 07833 053749 or use the contact form.
What we’re asked to look at in Winchester
Valleys carry a lot of water. Split linings, slipped valley tiles or debris can send that water under the coverings. The stain may appear well away from the valley itself.
It is worth booking a survey if you’ve seen:
- Condensation that looks like a leak
- Damp walls below an overflowing gutter
- Stains around a skylight
- Damp ceilings under a flat roof
For hotels and guest houses around Winchester, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Their insurance cover
- Whether VAT is added on top
- Is there a chance to talk the report through?
What we look for on each type of roof
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Where conditions allow, moisture readings and thermal imaging help narrow it down.
What happens on the day
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely, from ground level, from windows, in the roof space and by drone where it applies. The survey typically takes an hour or two for most homes, though a hard-to-trace leak can take longer. Visits in a place the size of Winchester range from flats and family homes to offices and blocks. Each building type brings its own access questions, from shared stairwells to locked plant rooms. Weekday and weekend visits are both available.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Before the survey
- Tell us where we can park nearby
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at
