How a roof leak investigation works in North Woolwich
Our roof leak investigations cover North Woolwich and the wider South East. We visit on weekdays, Saturdays and Sundays. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If it’s leaking right now, contain the water and keep it clear of electrics, and then phone 07833 053749 or use the contact form to arrange a visit. If you’ve noticed staining where a gutter or parapet meets the wall and stains around a skylight, we can find out what’s behind it, on valleys and parapet gutters, chimney stacks and the roof space alike.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers usually exclude wear and tear. A careful look in North Woolwich tells the two apart where the evidence allows. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Why get it checked now?
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Our price is from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT.

Wind, rain and roofs in North Woolwich
Eastbury Manor House, about 2.9 miles north-east, is one of the historic houses in the wider area around North Woolwich. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering and its details give the first clues when tracing where water is coming from.
If you run a business near Gallions Reach Shopping Park, a leak can close part of a shop or office, so finding the cause quickly matters. Take an older house close to St John's Church: old mortar, worn lead and slipped slates are the usual suspects when water gets in. Living close to Beckton District Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
North Woolwich is about 1 mile north of Woolwich, in Greater London. We carry out roof leak investigations for householders, landlords and businesses in North Woolwich. North Woolwich is one of the places in Greater London we cover for roof leak investigations. You can also see our page for London.

Different roofs, different checks
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. A low or cracked upstand is a common way in.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is checked from every safe viewpoint, and look for damp on the breast inside.
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
How we price roof leak investigations
Prices always include VAT. The things that change the price are:
- Whether thermal imaging or a drone is needed
- The size of the roof
- Extensions, dormers and garages with roofs of their own
- Which survey package you book
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
Booking your survey
Getting the details right at the start saves time. It helps to include:
- Any deadline, like an exchange date
- The address and postcode of the property
- Anything about access we should know
- Why you want a survey: buying, a leak, a storm or new work
For a price for roof leak investigations in North Woolwich, ring 07833 053749 or email us. A few details about the property and the roof help us give you an accurate price.
What we do, step by step
We’ll ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes an hour or two for most homes, though a hard-to-trace leak can take longer. In a London area like North Woolwich, 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 ground level, windows, the loft and, where it is safe, the roof itself.
- 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.
- The report explains the likely entry point and what needs attention.
Preparing for the visit
- Let us know about parking near the property
- Make a note of anything you’d like us to look at
- For a flat or shared roof, check access with the freeholder or managing agent

North Woolwich: your questions answered
Will parking be an issue for a roof survey in North Woolwich?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Is my home in North Woolwich listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do I need to be at home?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access.
Why is not the leak directly above the stain?
Water rarely drops straight down. It runs along rafters, battens or underlay before it drips, so the stain may be some distance from where it gets in. That’s why we trace the route rather than patching above the stain.
Can you trace a leak in dry weather?
Typically, yes. Damp materials can be found without rain. If a leak only appears in driving rain from one direction, we’ll tell you what we found and what’s most likely.
Is North Woolwich in your area?
Yes. We cover North Woolwich and the rest of Greater London. For a price, phone 07833 053749 or send us an email.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Rented homes, blocks and businesses
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out with the most urgent first where relevant, which helps when budgeting.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time.
