How a roof leak investigation works in Petersfield
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, while the repair is a separate matter. If you’ve noticed staining where a gutter or parapet meets the wall and damp patches next to the stack, a survey will tell you what’s going on.
In a town like Petersfield, older houses and newer estates leak in different ways. On older roofs it’s often slates, mortar and lead that has split or lifted; later homes can leak at valleys, verges and flat roofs over extensions. Knowing the cause tells you what to do next. It also tells you whether the problem is old wear or something more recent.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later.

Roof leak investigations in Petersfield: local notes
Uppark, about 4.1 miles south-east, is one of the historic houses in the wider area around Petersfield. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. A number of Hampshire villages keep thatched roofs on their older buildings. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. The covering and its details give the first clues when tracing where water is coming from.
For landlords with property near Petersfield station, tracing a leak quickly matters when a tenant is living with it. The streets around a church such as St Peter's Church are often among the oldest in a place, and if yours is one of the older homes nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:
- An intermittent leak that shows no trace on the day
- Plumbing leaks that look like roof leaks
- Carrying out the fix

DIY checks: what’s safe
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
The survey, step by step
We look at the roof from outside and, where it is relevant and there is safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. In Petersfield, parking is rarely complicated, though it’s useful to know about driveways or restrictions. The inspection covers what can safely be seen from outside, from windows and from the roof space, and from the roof itself where it is safe.
- 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 ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Find any records of previous roof work
- If you’re buying, check with the agent that we can get in
- Leave side gates unlocked
Booking a survey
Most bookings start with a short call: phone 07833 053749 or email us. The price is agreed before a date is set.
Advice
Common roof problems in Petersfield
Some water in the loft is not rain at all. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly where ventilation is poor. Drips from nails and damp underlay are typical signs.
Here are some of the things we see frequently:
- Damp patches next to the stack
- Damp walls below an overflowing gutter
- Water that shows only in certain storms
- Water dripping from rafters or underlay
Take a building like Petersfield Infant School: tracing a leak on a big roof starts with where the water appears and works back.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- Is VAT included in the price?
- Which limits apply to the survey
- Is there a chance to talk the report through?
Why it’s worth a survey now in Petersfield
Patching the spot above the stain frequently doesn’t work. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first. On a house in a town like Petersfield, wet loft insulation stops working and can stay damp for a long time. That’s an extra cost on top of the roof work itself.
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both with VAT included. We confirm the exact price before booking.

FAQs for Petersfield
How should I get ready for a visit in Petersfield?
Very little. Keep pets out of the way, leave side gates unlocked and have any old roof paperwork handy, and the visit in Petersfield can get straight on.
How do I find out if my home in Petersfield is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will you definitely find the leak?
We cannot promise it. Some leaks hide well, especially those that need wind-driven rain. Where the source is not certain, we list the likely routes in order.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. We always check what it shows with moisture readings.
How long does the visit take?
The visit normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. We will confirm what to expect when we arrange the visit.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. We’ll talk about access when booking.
Roof by roof
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is looked at from every safe vantage point.
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
