Flat roof survey in Alperton
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. You get a report with photos and our recommendations. We survey mastic asphalt, single-ply membranes and upstands and outlets, and common reasons people get in touch are a sagging deck under the covering and splits and cracks in the covering.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Alperton, the flat roof is often a shared part of the building.
The report works through the roof section by section, from the coverings down to the gutters. You’ll see the good as well as the bad.

What happens on the day
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes an hour or two at a typical home, and longer for a large or complex roof. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- You let us know about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
Before we arrive
- For a flat or shared roof, check access with whoever owns or manages the building
- Point out any leaks or damp patches
- Find any records of previous roof work
How to book
Booking is simple: just phone 07833 053749 or send us an email, tell us about the property and we’ll recommend the right survey. We confirm the price before anything is booked.
Advice
Why get it checked now?
Waiting for a stain inside means the water has already got through the layers. We can pick up worn covering and failing details sooner, while there is still time to plan the work. In Alperton, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Dealing with it early is far less disruptive.
Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, how it can safely be seen and the package you choose.

Practical tips
A little preparation and a few simple habits help. Our tips:
- Watch the ceilings below the flat roof for stains
- Clear roof outlets and gutters each autumn
- Book a survey every few years
- Ask contractors to protect the roof if they work on it
If you’re buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Keep foot traffic on a flat roof to a minimum. If access is needed, boards or walkways help protect the covering, and to keep well clear of rooflights and fragile sheeting.
For landlords and managing agents
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or email us.
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.
Honest limits
It is a careful look at the flat roof, not the whole story. The main limits are:
- A promise that the roof will not leak in future
- Fragile surfaces, which we don’t walk on
- What’s under the membrane without opening it up

Alperton: your questions answered
Is my home in Alperton listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. 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.
Do you look at commercial flat roofs near Alperton, like hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report is sent afterwards by email.
Is this a RICS survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can I check my roof myself?
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. Leave anything above ground level to a survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Flat and commercial roofs around Alperton
The wider area around Alperton has a long history of building, with Pitzhanger Manor about 2.1 miles south. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For hotels and guest houses around Alperton, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. If you own one of the older houses in the streets near St James Church Alperton, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you run a business near London Designer Outlet, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
