Roof leak investigations for New Southgate homes and businesses

Leave it or get it looked at?

Patching the spot above the stain often does not work. The real way in may be a metre or more away. An investigation finds the likely cause first. In New Southgate, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.

Roof leak investigation starts from £150, including VAT. What you pay depends on how big and how high the roof is, how it can safely be seen and which survey you book.

Why us?

  • Plain-English reports with photos
  • A sub-250g drone, flown with a CAA Flyer ID and Operator ID
  • PI and public liability insurance
  • An independent look at the roof

Roof leak investigation in New Southgate: what you get

A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us and so do photos. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. If you’ve noticed drips from nail tips in a cold loft and wet patches on loft insulation, a survey will tell you what’s going on, on the roof space, chimney stacks and valleys and parapet gutters alike.

Water getting into a London home often comes from a detail you cannot see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you’re tracing a leak or recording storm damage in New Southgate, those are among the first places to look. 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. That makes it useful now and a handy reference later, like when you want to compare after future work.

Can I check my roof myself?

The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.

A lot can be seen 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.

What happens on the day

When we arrive, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. The survey typically takes an hour or two at a typical home, and about three to four hours for a commercial roof. In a London area like New Southgate, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at everything that’s safely in view from the ground, windows, the loft and, where it is safe, the roof itself.

  1. We start with what you’ve seen: where the stain is and when it gets worse.
  2. Inside, we check the damp area and the roof space above it.
  3. Outside, we check every likely route in.
  4. Moisture readings and thermal imaging are used where they help.
  5. We email a report with photographs, the likely entry point and recommendations.

Preparing for the visit

  • Clear the way to the loft hatch
  • Leave side gates unlocked
  • Keep pets out of the way during the survey

What affects the cost of roof leak investigations

Several things affect the price of a survey:

  • Roof area
  • The use of thermal imaging or a drone
  • Building height and the viewpoints available
  • The type of building, from a house to a block or an office

Prices quoted always include VAT, and the report isn’t charged as an extra. Roof leak investigation starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Getting in touch

To price your survey accurately, we will ask about:

  • Whether there is a loft hatch, a shared roof or tricky access
  • Any deadline, such as an exchange date
  • Where water is showing inside, if it is
  • Why you want a survey: buying, a leak, a storm or new work

Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or drop us an email with the address and the days you’d prefer.

Common questions in New Southgate

Will parking be an issue for a roof survey in New Southgate?

It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.

Do you cover New Southgate?

Yes. We cover the whole of London and South East England, and New Southgate is part of that. Just call 07833 053749 or email us and let us know about the property.

How experienced are you?

Over 5,000 surveys so far, across 20+ years of surveying roofs.

Is it a structural engineer’s report?

No. Our survey is not a structural engineer’s report. If we see signs that need an engineer’s opinion, we’ll recommend one.

What should I do before you arrive?

Keep a note of when it leaks. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.

Do you carry out surveys on Saturdays and Sundays?

We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.

How long does the visit take?

On site, it typically takes an hour or two, more where the leak is intermittent or the roof is large. Report times depend on the package.

When you need someone else

Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:

  • Water from pipes, tanks or heating systems
  • A promise to find every leak on a single visit
  • A structural engineer’s report

If in doubt, call 07833 053749 or send us an email and we will suggest the right survey. The full list of what we check.

Roof leak investigations around New Southgate

Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. The covering and its details give the first clues when tracing where water is coming from. About 2.9 miles south-west lies Heath Hall, a reminder of how long the area around New Southgate has been built on. 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.

Living close to O. R. Tambo Recreation Ground is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall. Anyone responsible for a site like St Paul's CofE Primary School N11 will know that a leak through a large roof is often found some distance from where the water shows inside. If you let a flat or house near New Southgate station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
