Questions from North Wembley

Is North Wembley in the area you cover?

We do. Every survey there gets the same written report with photographs.

How do I find out if my home in North Wembley is listed?

Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.

Will you go up on the roof?

Not unless it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed.

I live in a flat. Can you survey the roof?

Yes. A shared roof needs access agreed first. Mention it when you contact us and we’ll explain what’s needed.

Will you definitely find the leak?

We cannot promise it. Some leaks hide well, particularly those that need wind-driven rain. If we cannot be sure, the report ranks the possible sources.

Will you check the loft?

Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps.

Does someone need to be in?

Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.

Roof leak investigation in North Wembley

Not every drip is a leak. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Knowing which it is means the right fix can be done, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. We survey flat roof details, lead flashings and chimney stacks, and common reasons people get in touch are water through the ceiling under a flat roof and drips in the loft during heavy rain.

In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. In North Wembley, we inspect what we can reach safely and are given access to. It helps to know when the water appears and in what weather.

With the Standard Survey, you also get 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.

What happens on the day

We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two at most homes, while a commercial roof takes nearer three to four hours. In North Wembley, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when you book.

  1. You get in touch with details of the leak and any photos.
  2. The visit starts indoors, at the stain and in the loft.
  3. We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
  4. We use moisture detection, and thermal imaging where it’s useful.
  5. We email a report with photographs, the likely entry point and recommendations.

How to prepare

  • Check the loft hatch can be reached
  • Check pets are kept safely away
  • Let us know where we can park nearby

Prices for roof leak investigations in North Wembley

All our prices include VAT. The things that change the price are:

  • Extensions, dormers and garages with roofs of their own
  • The roof’s overall size
  • The type of building, from a house to a block or an office
  • The height of the building and how the roof can safely be seen

For a price for your roof in North Wembley, ring 07833 053749 or drop us an email with the address and a few details. The price is agreed before a date is set.

What we need to know

You do not need to know any roofing terms. It’s enough to tell us:

  • Pictures of the roof from a safe spot, if you have them
  • The style of property, from a terrace to a block
  • The address and postcode of the property
  • The reason for the survey, such as buying, a leak or storm damage

Photos help, if you have them. Take them safely from the ground or a window. To get started, ring 07833 053749 or drop us an email.

Tips from our surveys

A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:

  • Leave roof access to professionals
  • Keep a photo record of the damp patch
  • Write down the wind direction and rain when it leaks
  • Move stored items away from the hatch

We email the report to you. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.

After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.

Roof leak investigations around North Wembley

Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Different coverings let water in at different points, which shapes where the search starts. Northolt Manor, about 2.9 miles west, is one of the historic houses in the wider area around North Wembley. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.

Trees in and around Preston Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. If yours is one of the older homes in the streets near Church of St John, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks. For businesses in and around places such as London Designer Outlet, a quick answer on where water is coming in keeps a business running.

DIY checks: what’s safe

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. Don’t go up yourself.

A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.

For landlords and managing agents

We also survey roofs for businesses and commercial landlords. Bigger roofs take more time, and they’re priced for the size.

Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Let us know about it when you book and we’ll plan the visit with that in mind.

Honest limits

No survey can tell you everything, and it’s better to know them up front. Bear these in mind:

  • Faults hidden behind ceilings or boarding
  • A structural engineer’s report
  • An intermittent leak that shows no trace on the day

Not sure which survey suits your roof? You can call 07833 053749 or send us an email and we will tell you before booking. What a survey covers and does not.
