Roof leak investigation in Winchmore Hill, Greater London
Know where you stand with the leaking roof before you spend money on it. We carry out roof leak investigations in Winchmore Hill, with photos and a clear written report.
- A leak that comes and goes with the weather
- Drips from nail tips in a cold loft
- Damp patches next to the stack
Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
A lot can be seen 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.
Roof leak investigation in Winchmore Hill
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot and so do photos. Even on a dry day, a leak usually leaves clues: stained timbers, tide marks and damp underlay. Moisture readings show where materials are still wet. Common reasons to book are water dripping from rafters or underlay and condensation that looks like a leak, across slate and tile slopes, the roof space and lead flashings.
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. For a leak or storm damage in Winchmore Hill, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
What you get is a clear record of the leaking roof on the day we saw it. It is useful right away, and a good reference for later, for example when you want to check whether anything has changed.

Prices for roof leak investigations in Winchmore Hill
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- Whether you choose the Basic, Standard or Premium Survey
- Extra roofs, like extensions, dormers or garages
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.
What to tell us when you get in touch
To price your survey accurately, we’ll ask about:
- Access details, such as a loft hatch or a shared roof
- Where water is showing inside, if it is
- Pictures from the garden or a window, if you have them
- Dates you’re working to, such as exchange
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or send us an email whenever suits you.

Roof leak investigations in Winchmore Hill: local notes
About 2.6 miles south-east lies Bruce Castle, a reminder of how long the area around Winchmore Hill has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in.
Trees in and around Grovelands Park shed leaves that can end up in nearby gutters. Anyone responsible for a site like St. Paul's School will know that tracing a leak on a big roof starts with where the water appears and works back.
Winchmore Hill is about 2 miles north-west of Edmonton, in Greater London. Winchmore Hill is one of many places we visit across Greater London. Our Greater London coverage includes Winchmore Hill and the places around it. You can also see our page for London.

Common roof problems in Winchmore Hill
Flat roofs fail with age and wear. Felt frequently lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Leaks often start at the edges, upstands and outlets.
Most people get in touch after spotting one of these:
- Water marks that spread in wet weather
- Water through the ceiling under a flat roof
- Damp on a chimney breast
- Leaks at a dormer or roof window
If you run a business near Edmonton Green Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
What to check before booking
- Is VAT included in the price?
- When you will get the report
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether the loft space is looked at, where there is one
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it when booking and we’ll plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take an hour or two at a typical home, and more on a big or complicated roof. Surveys in Winchmore Hill can be booked for any day of the week. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.

Questions from Winchmore Hill
Is Winchmore Hill in the area you cover?
Yes, Winchmore Hill is one of the places we work. The survey and report are the same in Winchmore Hill as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in Winchmore Hill is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you climb onto every roof?
Only where it’s safe to do so. We inspect whatever is safely visible: from the ground, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. Anything we cannot see is noted in the report.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
How experienced are you?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.
What should I do before you arrive?
Note when the leak appears and what the weather was doing. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Will you definitely find the leak?
We can’t promise it. Water can travel a long way, and some leaks only show in particular storms. If we can’t be sure, the report ranks the possible sources.
Honest limits
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Whether rotten timbers meet design loads
- A promise to find every leak on a single visit
- Carrying out the fix
