Roof leak investigations for homes and businesses in Winnall
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. A central valley gutter on a butterfly roof often turns out to be the source. Parapet walls and their gutters are checked from wherever it is safe. Our report shows what we found, with photos. We survey chimney stacks, rooflights and dormers and lead flashings, and people most frequently book us about damp underlay across a wide area and water that shows only in certain storms.
Chimney stacks on older houses around places like Winnall can let water in, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast is not always rain from above, which is why it is worth tracing properly. The stack, its flashings and the loft space beside it are all worth checking.
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, for instance when you want to check whether anything has changed.

What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey.

Practical tips
Small things make a difference. Some pointers:
- Mention any plumbing above the damp area
- Do not climb onto the roof to look
- Record whether it leaks in every downpour or only some
- Don’t touch fittings that water is reaching
If condensation is the cause, we explain it, with recommendations on ventilation. That avoids roof work that wouldn’t help.
Keep the loft space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation doesn’t block airflow at the eaves.
Why act early in Winnall
Patching the spot above the stain often does not work. The real way in may be a metre or more away. We find the probable source before anyone starts work. Tradespeople may need to travel further to a smaller place like Winnall, so it is useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.

Leaks and storm damage in Winnall
What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing. 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. The covering and its details give the first clues when tracing where water is coming from.
If you run a hotel or guest house in or near Winnall, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition. If your house is among the older ones in the streets near Church of St John the Baptist, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

Questions from Winnall
Do you cover Winnall?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my home in Winnall listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us when you book.
Do you use thermal imaging to find leaks?
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 many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
What we do, step by step
The visit typically starts outside and finishes in the loft: outside views come first, then the roof space if there’s safe access. All told, expect about one to two hours at a typical home, while a commercial roof takes nearer three to four hours. In a smaller place like Winnall, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can frequently be seen well from the ground, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- From the roof space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- We email a written report showing where the water most likely gets in.
How to prepare
- Gather any invoices or paperwork from past roof work
- Check the loft hatch can be reached
- Tell us where we can park nearby

Do you need a roof leak investigation in Winnall?
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Common reasons to book include:
- Ceiling stains that grow after rain
- Wet patches high on an inside wall
- Drips in the loft during heavy rain
- Staining around the chimney inside
Trees in and around St. Cross Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching.
Questions to ask before booking
- What exactly goes into their report
- Whether they hold professional indemnity and public liability insurance
- What’s outside the scope of the survey
- Their track record with similar roofs
