Roof leak investigations for homes and businesses in Strawberry Hill
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. Each one is looked at from wherever it’s safe to see it. We survey lead flashings, rooflights and dormers and the roof space, and people most frequently book us about drips from nail tips in a cold loft and drips in the loft during heavy rain.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you’re tracing a leak or recording storm damage in Strawberry Hill, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What else we do in Strawberry Hill
How the survey works
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take about 1–2 hours, more where the leak is intermittent or the roof is large. For a visit in Strawberry Hill, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at whatever is safely visible from the ground, windows, the loft and, where it is safe, the roof itself.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- Unlock side gates and any roof access doors
- Let us know about any leaks, stains or damp patches you know of
- If you’re buying, check with the agent that we can get in
Arrange a survey
Most bookings start with a short call: phone 07833 053749 or send us an email, and we will ask about the building and what you need. The price is agreed before a date is set.

Should I look at the roof myself first?
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Strawberry Hill roofs and the weather
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Strawberry Hill is one of them, bay roofs, hips and later dormers each have their own details. Different coverings let water in at different points, which shapes where the search starts. Strawberry Hill House, about 0.1 miles south-west, is one of the historic houses in the wider area around Strawberry Hill. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
The streets around a church like Holy Trinity Church are frequently among the oldest in a place, and if you own one of the older houses nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you look after a building such as Kneller Hall Senior School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. For landlords with property near Strawberry Hill station, a clear finding on where water gets in helps you brief a roofer straight away.

Why act early in Strawberry Hill
Water and electrics don’t mix. Keep away from any fitting that water is reaching. Finding where the water is getting in should follow straight away. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.

FAQs for Strawberry Hill
Do you carry out roof surveys in Strawberry Hill?
We do. The survey and report are the same in Strawberry Hill as anywhere else, and visits run on weekdays and weekends.
Is parking a problem for a survey in Strawberry Hill?
Parking in Strawberry Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when booking.
Do you climb onto every roof?
Only where it is safe to do so. We look at everything that can safely be seen: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
Is there anything I need to do ahead of the visit?
Keep a note of when it leaks, and take photos. Clear access to the loft. Keep away from any light or socket that water is reaching.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we’ll plan the survey around it.
Can you inspect my roof with a drone?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
How long will you be at the property?
It normally takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Take dated photos of the leak
- Let us know about any past repairs to the roof
- Keep water away from lights and sockets
- Check whether pipes or tanks run near the stain
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant.
Do not block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Make sure insulation doesn’t block airflow at the eaves.
Different roofs, different checks
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. Outlets and the area around them are checked.
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. Even a single gap can let water in, especially in driving rain.
