Roof leak investigations for homes and businesses in Erith
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot, along with any photos you’ve taken. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. Common reasons to book are damp underlay across a wide area and brown rings on upstairs ceilings, on rooflights and dormers, valleys and parapet gutters and slate and tile slopes.
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. Insurers normally exclude wear and tear, so it helps to know whether damage is old or new. A careful look in Erith tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Common questions in Erith
Will parking be an issue for a roof survey in Erith?
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.
Is Erith in the area you cover?
Yes, Erith is one of the places we work. The survey and report are the same in Erith as anywhere else.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
How long does the visit take?
It typically takes between one and two hours for a house, with bigger or more complicated roofs taking longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we’re allowed to reach.
Can every leak be traced?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but some only appear in certain weather. We report what we found and the likeliest sources.
What does a roof survey cost?
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.
Why get it checked now?
Water and electrics do not mix. Keep away from any fitting that water is reaching and have an electrician check it. Finding where the water is getting in should follow straight away. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Roof leak investigation starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we can help you choose.

What else we do in Erith
Wind, rain and roofs in Erith
Hall Place and Gardens, about 2.3 miles south, is one of the historic houses in the wider area around Erith. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. 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. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
Homes near green spaces such as Wildspace Conservation Park can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls. If you look after a building such as Christ Church (Erith) CofE Primary School, a leak through a large roof is frequently found some distance from where the water shows inside. Take an older house close to Christ Church: water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Erith is about 3 miles north-west of Dartford, in Greater London. Erith is part of the area we cover across London and South East England. Our area takes in places right across Greater London. We also survey roofs in London.

How it works
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so in Erith we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Tell us about parking before the day
- Jot down any questions you want answered
- If the roof is shared, arrange access with whoever manages the building
Book a survey
A quick phone call is normally the easiest start: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Advice
Tips that help
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Have an electrician check any wet fittings
- Photograph the stain each time it appears
- Tell us if there are tanks or pipes in the loft
- Stay off ladders and the roof
We email the report to you, with photos of what we found. 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.
Plan a roof survey every few years. They’re where most leaks start, and catching wear early keeps water out.
What this survey cannot tell you
A survey is a close look at the leaking roof, but it cannot do everything. The main limits are:
- A promise to find every leak on a single visit
- Whether rotten timbers meet design loads
- Plumbing leaks that look like roof leaks
