How a flat roof survey works in West Drayton
Buying a home with a flat-roofed extension, dormer or garage? It is useful to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP frequently go on for longer. We set out the type of covering, its condition and the defects we found, with photos of each. That gives you facts to raise with the seller or agent. We survey felt flat roofs, EPDM rubber and single-ply membranes, and common reasons people get in touch are outlets that hold water back and failed upstands where the roof meets a wall.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In West Drayton, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

How it works
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. A typical survey takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- 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.
Preparing for the visit
- Leave side gates unlocked
- If you are buying, let the agent know when we’re coming
- Keep pets in another room
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or use the contact form when you’re ready.
Advice
FAQs for West Drayton
Is my home in West Drayton listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Will parking be an issue for a roof survey in West Drayton?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we will work around them.
Does the weather affect the survey?
It depends on the weather and the survey. High wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
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. The report names the covering and explains its condition.
Do you give a life expectancy for the roof?
There’s no honest way to give an exact number of years. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but the report tells you how your roof is really doing.
What do I do with the report?
You will get the report by email, with photographs and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Flat roof surveys in West Drayton: local notes
With Ickenham Hall about 4.2 miles north, West Drayton sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in West Drayton is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take an older house close to Church of St Martin: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Controlled parking zones are common in London, so mention any permit rules for West Drayton, along with any off-street space.

Surveys for landlords and agents in West Drayton
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we’ll plan the survey around it.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
Signs you need a flat roof survey in West Drayton
The surface of a flat roof heats up and cools down far more than the rooms below. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
Look out for signs like these:
- Failed seals around rooflight kerbs
- Ponding water that does not drain away
- Outlets choked with leaves and silt
- Gaps at upstands and abutments
If you look after a building like West Drayton Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

- Whether you get a written report with photos
Why act early in West Drayton
Before replacing a flat roof, it is useful to know if you really need to. Sometimes some details are to blame, and sometimes the covering has simply had its day. The report sets out what we found, so you can make that decision with a roofer. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Our price is from £150, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.
Why book us in West Drayton
- More than 20 years surveying roofs
- Drones and thermal imaging where it applies
- An independent look at the roof
- Surveys on any day of the week
Should I look at the roof myself first?
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
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. Do not go up yourself.

What we look for on each type of roof
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. We note where this is happening and how widespread it looks.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
