Flat Roof Survey in Brentford
Need a flat roof survey in Brentford? We can help, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Dips that suggest the deck is deflecting
- Outlets choked with leaves and silt
- Splits, cracks and crazing
What you can safely check yourself
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Flat roof surveys for homes and businesses in Brentford
Our Basic Survey, from £150, gives you a visual inspection with photos and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Larger commercial roofs are quoted for their size. We survey single-ply membranes, EPDM rubber and mastic asphalt, and the problems we are asked to look at most are ponding water that doesn’t drain away and outlets choked with leaves and silt.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Brentford, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
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.

How the survey works
It’s useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. London terraces rarely offer a view of the whole roof from one spot, so a visit in Brentford moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, tell us who can let us into the shared parts.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Before the survey
- Clear the way to the loft hatch
- Keep pets inside or away from the areas we’re looking at
- Find any records of previous roof work

Advice
When to book a survey in Brentford
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
We are often asked to look at:
- Gaps at upstands and abutments
- Damaged trims at the roof edge
- A sagging deck under the covering
- Cracked or split membrane
If you look after a building such as St Paul's CofE Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before booking anyone
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Their report turnaround times
- Whether you can ask questions once you have the report
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Flat and commercial roofs around Brentford
Brentford has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. The wider area around Brentford has a long history of building, with Kew Palace about 0.5 miles south-east. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Brentford station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you run a hotel or guest house in or near Brentford, a roof problem can mean rooms out of use.
Brentford is about 2 miles south of Ealing, in Greater London. From houses to flats and shops in Brentford, the roof can be surveyed on a weekday or at the weekend. Our Greater London coverage includes Brentford. For surveys nearby, see our London page.
We work across TW8, W3, W4 and W5 for flat roof surveys and the streets around it. We cover properties on High Street, Market Place and New Road. Brentford is on the A4 and A315, which makes it straightforward to reach. Close by, we survey roofs in Brentford End (1 mile south-west), Northfields (1 mile north-west), Gillette Corner (1 mile west), Isleworth (2 miles south-west) and Spring Grove (2 miles west). Within a short drive, we also cover London (9 miles east), City of Westminster (7 miles east), Marylebone (7 miles east), Kensington (4 miles east), St Pancras (8 miles east) and Shoreditch (10 miles east).
Around Brentford
We work in homes and buildings around Library for Iranian Studies, Brentford School for Girls and Kew College Prep and the streets around them. Nearby too are The Brook pub (less than half a mile south-west) and Kew Green (0.7 miles south-east). Brentford has its own railway station: Brentford station. Other landmarks nearby include Treaty Centre (3 miles south-west) and Musical Museum (0.5 miles east). Not far away are Kew Gardens Lake and Long Wood.
Leave it or get it looked at?
Ponding seldom gets better on its own. It usually points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Finding the cause now keeps more options open. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.

What a survey costs
When we price a survey, we consider:
- Roof area
- Features like valleys, chimneys, dormers and parapets
- Height and safe access
- If the survey needs thermal imaging or a drone
Prices start from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
What we need to know
You don’t need to know any roofing terms. It is enough to tell us:
- When you need the report by
- Why you want a survey: buying, a leak, a storm or new work
- Access details, such as a loft hatch or a shared roof
- The address and postcode of the property
A quick phone call is typically the easiest start: phone 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
Brentford: your questions answered
Can you look at the flat roof of a hotel or office near Brentford?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Does a conservation area affect roof work in Brentford?
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.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. The roof space can show things the outside cannot, like damp timbers, staining or daylight.
Will you photograph what you find?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Surveys for landlords and agents in Brentford
Letting agents frequently book on a landlord’s behalf. We agree a time with the tenant beforehand.
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
