Roof leak investigations for homes and businesses in Islington
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey lead flashings, the roof space and chimney stacks, and common reasons people get in touch are leaks at a dormer or roof window and water that shows only in certain storms.
Water getting into a London home often comes from a detail you cannot see from the street: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you’re tracing a leak or recording storm damage in Islington, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

Islington questions
Does a conservation area affect roof work in Islington?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you carry out roof surveys in Islington?
Yes, Islington is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or use the contact form with the address and a few details.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Can every leak be traced?
We cannot promise it. Water can travel a long way, and some leaks only show in particular storms. Where the source is not certain, we list the likely routes in order.
Can you find a leak when it isn’t raining?
Typically, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
Will you go up on the roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.

Different roofs, different checks
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. We check outlets and the covering around them.
Parapet and box gutters
We check the linings, joints and outlets where we can see them safely.
Roof leak investigations in Islington: local notes
With Dr Johnson's House about 1.6 miles south, Islington sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Each of these roof types has its own typical places for water to get in.
Shop and office owners around Brunswick Centre may find that a quick answer on where water is coming in keeps a business running. Trees in and around Barnard Park shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall.
Islington is about 3 miles north-east of City of Westminster, in Greater London. Houses, flats, blocks and commercial buildings in Islington can all book roof leak investigations, with a written report and photographs every time. Across Greater London, we cover Islington and the places around it.

When to book a survey in Islington
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it, frequently well away from where it shows.
Problems we come across frequently include:
- Damp underlay across a wide area
- Wet patches high on an inside wall
- Damp patches next to the stack
- Damp ceilings under a flat roof
Take a building like Islington Proprietary School: on a building that size, finding the source of a drip means looking well beyond the stain.

Landlord and commercial surveys in Islington
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, ring 07833 053749 or use the contact form with the addresses.
What you can safely check yourself
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours at a typical home, while a commercial roof takes nearer three to four hours. You are welcome to ask questions while we are there. For a visit in Islington, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from ground level, windows, the loft and, where it’s 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.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Keep pets in another room
- Have any paperwork from past roof work to hand
