Perivale Roof Leak Investigation
Tracing where water is getting into your roof in Perivale, carried out by an experienced roof surveyor. Every survey comes with a written report and photos.
- Water coming in around a roof light or dormer
- Leaks below a flat extension roof
- Wet patches on loft insulation
Roof leak investigation in Perivale
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. A central valley gutter on a butterfly roof often turns out to be the source. Parapet walls and their gutters are checked from wherever it is safe. Our report shows what we found, with photos. If you’ve noticed wet patches on loft insulation and water that shows only in certain storms, a survey will tell you what’s going on, whatever the roof.
In London, leaks frequently start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Perivale, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
The report records the leaking roof as we found it on the day. It is useful straight away, and a good reference for later.

Why it is worth a survey now in Perivale
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. We look past the obvious spot and check each likely route. That is frequently what breaks the cycle. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.

FAQs for Perivale
How do I find out if my home in Perivale is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you carry out roof surveys in Perivale?
Yes, Perivale is one of the places we work. The survey and report are the same in Perivale as anywhere else.
Can you always find the source?
We cannot promise it. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
How do you tell a leak from condensation?
It is a common question. A leak typically shows in one area and follows rain, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
What’s the best way to book?
To book, phone 07833 053749 or send us an email and tell us the address and what you need to know. We’ll confirm the price and agree a day with you.
Can a leak be traced on a dry day?
Frequently, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Some leaks only show in particular weather, so your photos and notes from wet days are very useful.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe vantage point, photograph what we find and make notes for the report. It typically takes between one and two hours on an ordinary house, and about three to four hours for a commercial roof. In a London area like Perivale, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at whatever is safely visible from the ground, windows, the loft and, where it’s safe, the roof itself.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near 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 vantage point.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Let us know about parking near the property
- Move anything stored under the loft hatch
- Jot down any questions you want answered
How to book

Advice
Perivale roofs and the weather
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Perivale is one of them, bay roofs, hips and later dormers each have their own details. Knowing the roof type helps narrow down where water may be getting in. The wider area around Perivale has a long history of building, with Pitzhanger Manor about 2 miles south. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to South Greenford station may find that a tenant living with a leak needs the cause found, not just the stain painted over. The streets around a church such as St. Mary with St. Nicholas - Perivale are often among the oldest in a place, and if you own one of the older houses nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Perivale is about 1 mile east of Greenford, in Greater London. We carry out roof leak investigations for homeowners, landlords and businesses in Perivale. Our Greater London coverage includes Perivale. There is also a page for London.

DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
What a roof leak investigation doesn’t cover
Before you book, it is worth knowing what a survey will not do:
- What’s under the covering or behind the plaster
- A promise to find every leak on a single visit
- Putting the leak right
If in doubt, ring 07833 053749 or email us and we’ll point you to the right survey before booking. What a survey covers and does not.

Signs you need a roof leak investigation in Perivale
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
Here are some of the things we see often:
- Drips in the loft during heavy rain
- Damp underlay across a wide area
- A leak that comes and goes with the weather
- Staining where a gutter or parapet meets the wall
Take a building like St John Fisher Catholic Primary School: on a building that size, finding the source of a drip means looking well beyond the stain.
