About our roof leak investigation in Staples Corner
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. We survey slate and tile slopes, the roof space and valleys and parapet gutters, and the problems we’re asked to look at most are leaks below a flat extension roof and staining around the chimney inside.
In London, leaks frequently 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 Staples Corner, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

Roof leak investigations around Staples Corner
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. The covering and its details give the first clues when tracing where water is coming from. With Heath House about 2.2 miles east, Staples Corner sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Brent Cross West station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused. For businesses in and around places like Brent Cross Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Staples Corner is about 1 mile south of Hendon, in Greater London. Surveys in Staples Corner work the same way as everywhere we cover: a careful inspection, photographs and a written report. Our Greater London coverage includes Staples Corner. Our London page covers surveys nearby.

The survey, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. Most surveys take an hour or two for most houses, and longer for a large or complex roof. London terraces rarely offer a view of the whole roof from one spot, so in Staples Corner we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around 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.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Make sure we can get to the back of the property
- Let us know about any leaks, stains or damp patches you know of
- Agree roof access with the managing agent if it is shared

What we look for on each type of roof
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped.
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. When their outlets block, water rises over the lining and runs indoors.
Signs you need a roof leak investigation in Staples Corner
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. Leaks from valleys frequently show up some distance away inside.
These are some of the problems a survey can pick up:
- Drips from nail tips in a cold loft
- Brown rings on upstairs ceilings
- A leak that comes and goes with the weather
- Damp walls below an overflowing gutter
For an older house near a landmark such as Church of St John, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Before you book anyone
- Will the report include photos?
- How long the report takes to arrive
- Whether VAT is in the quoted price
- What insurance they carry
Should I look at the roof myself first?
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
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.

Questions from Staples Corner
Will parking be an issue for a roof survey in Staples Corner?
It rarely stops a survey, but it’s worth planning. Let us know what parking is available nearby, and the visit is planned around it.
Does a conservation area affect roof work in Staples Corner?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Are you structural engineers?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How long does a roof leak investigation take?
Allow about 1–2 hours, more where the leak is intermittent or the roof is large. We will confirm what to expect when we arrange the visit.
How much does a roof leak investigation cost in Staples Corner?
Roof leak investigation starts from £150, including VAT. The final figure depends on the roof and the package you choose, and it’s agreed before booking.
Can you find a leak when it is not raining?
Usually, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
