Roof leak investigation in Harringay: what you get
Our roof leak investigations cover Harringay and the wider South East. Surveys are carried out on weekdays and at weekends. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then phone 07833 053749 or email us. We survey lead flashings, valleys and parapet gutters and the roof space, and the problems we are asked to look at most are damp patches next to the stack and staining where a gutter or parapet meets the wall.
London’s Victorian and Edwardian roofs have frequently been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Insurers normally exclude wear and tear, so it is useful to know whether damage is old or new. A careful look in Harringay tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Why it’s worth a survey now in Harringay
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. An investigation now gives you time to plan the work. Any roof job in Harringay means planning around parking, neighbours and access. That’s a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We will give you the figure before anything is booked.

Tips from our surveys
Small things make a difference. Our tips:
- Tell us if there are tanks or pipes in the loft
- Do not climb onto the roof to look
- Write down the wind direction and rain when it leaks
- Put a bucket under the drip and move valuables
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that is not clear.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and catching wear early keeps water out.
Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
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, using safe viewpoints and a drone where applicable.
Wind, rain and roofs in Harringay
With Bruce Castle about 1.6 miles north-east, Harringay sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Harringay is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. The covering and its details give the first clues when tracing where water is coming from.
For site and facilities teams at buildings like South Harringay Infant School, tracing a leak on a big roof starts with where the water appears and works back. Landlords with a home close to Harringay Green Lanes station may find that tracing a leak quickly matters when a tenant is living with it.

Surveys for landlords and agents in Harringay
Where a roof is shared: we need access agreed with the freeholder or managing agent. Mention it when you contact us and we’ll plan the visit with that in mind.
Letting agents can arrange access with tenants. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
What we’re asked to look at in Harringay
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, often well away from where it shows.
Most people get in touch when they’ve noticed one of these:
- Water through the ceiling under a flat roof
- Water marks that spread in wet weather
- Stains around a skylight
- Damp walls below an overflowing gutter
Living close to Chestnuts Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.
Questions to ask before booking
- What follow-up you get after the report
- Whether any drone flown is registered with the CAA

- Is VAT included in the price?

What else we do in Harringay
How it works
The visit typically starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect about one to two hours, more where the leak is intermittent or the roof is large. From the street, a London terrace normally shows only its front slope or parapet, so in Harringay we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Make sure pets are kept safely away
- Show us where any leaks or stains appear
- Move anything stored under the loft hatch

Harringay questions
Is parking a problem for a survey in Harringay?
Sometimes, yes. If Harringay has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
How do I find out if my home in Harringay is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you fly a drone over my roof?
Yes, where it applies and safe. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Do you work in Harringay?
Yes, we do. Harringay is part of the area we cover, and the service is the same as everywhere else we work.
Do you need to get into the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
How much is a survey?
Our price is from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT.
