Questions from Fish Island
Can parking be tricky for a visit in Fish Island?
It depends on the street. If Fish Island has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Do you cover Fish Island?
We do. The survey and report are the same in Fish Island as anywhere else.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Will you walk on the roof?
Only if it’s safe. We check everything that can be seen safely: from ground level, from windows, from inside the loft space, from the roof where it is safe and by drone where it applies. Anything we can’t see is noted in the report.
How fast do 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. If you have a deadline, like an exchange date, tell us as you book.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Roof leak investigation in Fish Island: what you get
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it’s needed. Typical surveys look at stains around a skylight and brown rings on upstairs ceilings, across rooflights and dormers, slate and tile slopes and lead flashings.
London’s Victorian and Edwardian roofs have frequently been repaired many times. Telling wear from a one-off event matters, because insurers normally exclude wear and tear. A careful look in Fish Island tells the two apart where the evidence allows. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Landlords, agents and block managers in Fish Island
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
What we can’t see
It’s a careful look at the leaking roof, not the whole story. Its limits include:
- The repair itself (the investigation finds and reports the cause)
- Whether rotten timbers meet design loads
- Water from pipes, tanks or heating systems
Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we’ll tell you. What a survey covers and does not.

Fish Island roofs and the weather
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Fish Island is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Knowing the roof type helps narrow down where water may be getting in. The wider area around Fish Island has a long history of building, with Sutton House about 1.3 miles north-west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For businesses in and around places such as Westfield Stratford City, finding where water is getting in quickly keeps disruption down. If yours is one of the older homes in the streets near St Mary of Eton, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
Fish Island is about 1 mile west of Stratford, in Greater London. We carry out roof leak investigations for homes and businesses in Fish Island and nearby. Our area takes in places right across Greater London.

What we’re asked to look at in Fish Island
Some water in the loft isn’t rain at all. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, especially where ventilation is poor. Wet nail tips and damp underlay over a wide area are classic signs.
It is worth booking a survey if you’ve seen:
- Wet patches high on an inside wall
- Damp on a chimney breast
- Leaks below a flat extension roof
- Water dripping from rafters or underlay
For landlords with property near Hackney Wick station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

How the survey works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes between one and two hours at most homes, rising to roughly 3–4 hours on a commercial building. London terraces rarely offer a view of the whole roof from one spot, so a visit in Fish Island moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near 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.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Keep pets out of the way during the survey
- Have any questions written down, so nothing gets missed
- If it is not your property yet, arrange access through the agent
Getting a price
Booking is simple: just call 07833 053749 or email us and give us some details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.

Practical tips
Over many surveys, some simple habits stand out:
- Move stored items away from the hatch
- Let us know about any past repairs to the roof
- Take dated photos of the leak
- Note the weather when the leak shows
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Check the loft after heavy rain, with care and a good torch. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
