Flat roofs in Mortlake
Chiswick House, about 1.3 miles north, is one of the historic houses in the wider area around Mortlake. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take a building like Thomson House School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Mortlake station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you live in an older home near All Saints' Church, flat-roofed rear additions and dormers added over the years are worth checking.

How a flat roof survey works in Mortlake
Many commercial buildings and blocks of flats have big flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photos so work can be planned and budgeted. We quote commercial roofs on their size and how they’re reached, so please phone 07833 053749 or email us with the address and an idea of the roof’s size. If you’ve noticed blistering in felt or asphalt and dips that suggest the deck is deflecting, a survey will tell you what’s going on.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Mortlake, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

How it works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. Most surveys take about 1–2 hours for a house, and longer for a large or complex roof. From the street, a London terrace usually shows only its front slope or parapet, so in Mortlake 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 agree the roof to be surveyed, its use and any leaks you know about.
- We check the roof from ground level, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
Before the survey
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
- Keep pets out of the way during the survey
Arrange a survey
If you have photos of the roof, send them over. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, phone 07833 053749 or use the contact form.

What happens if roof problems are left?
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. Once you’ve exchanged, any work on the roof is down to you. A report gives you facts to put to the seller or agent. In Mortlake, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Take a look at how roof surveys are priced and our case studies.
Roof by roof
Felt and built-up roofs
A felt roof often lasts around 15 to 20 years, though quality and upkeep make a big difference. We record how yours is doing and where it is weakest.
Single-ply membranes
Single-ply relies on its welded laps staying sound. We look at seams, corners and the joints around outlets and upstands.
What this survey can’t tell you
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
- Whether old sheeting or boards contain asbestos
- A promise that the roof won’t leak in future

FAQs for Mortlake
Is parking a problem for a survey in Mortlake?
It can be, so it is useful to tell us about permits, visitor bays or off-street space as you book. That way the visit can be planned around it.
Does a conservation area affect roof work in Mortlake?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Can you survey a flat roof on an office or unit?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
How much does a flat roof survey cost in Mortlake?
Flat roof survey starts from £150, including VAT. We confirm the exact price before booking. For a price, call 07833 053749 or drop us an email.
Can you survey any kind of flat roof?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. We record what the covering is and how it is holding up.
Do you check flat roofs for asbestos?
Asbestos testing isn’t part of our survey. If we see materials that could contain it, such as cement sheets on a building from before 2000, we flag them and recommend a specialist asbestos surveyor.
Will you photograph what you find?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Prices for flat roof surveys in Mortlake
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Extra roofs, like extensions, dormers or garages
- Features like valleys, chimneys, dormers and parapets
- Which survey package you book
- Any need for thermal images or a drone flight
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
What to let us know when you contact us
To price your survey accurately, we’ll ask about:
- When you need the report by
- Anything about access we should know
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from the ground or a window
When you’re ready to go ahead, ring 07833 053749 or use the contact form. We’ll suggest a package, agree the price and find a date, weekday or weekend.
Surveys for landlords and agents in Mortlake
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time, so they’re priced to suit.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
