Flat roof surveys for homes and businesses in Preston
If the house you’re buying has a flat roof on an extension, dormer or garage, it’s worth knowing its condition before exchange. Felt roofs frequently last around 15 to 20 years, while EPDM and GRP frequently last longer. Our report records the covering, how it is holding up and any defects we can see, with a photo of every defect. You then have something specific to put to the seller or agent. We survey single-ply membranes, felt flat roofs and EPDM rubber, and people most frequently book us about ponding water that doesn’t drain away and outlets that hold water back.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Preston, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to.

What a flat roof survey looks like in Preston
Preston has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as London Designer Outlet, the flat roofs over shops and commercial units are worth checking before a leak, not after. Take a building like Preston Park Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Preston is about 1 mile north of Wembley, in Greater London. We survey roofs in Preston and the rest of Greater London. We cover towns and villages across Greater London. You can also see our page for London.
Every address in HA9, HA3 and HA0 is within our area for flat roof surveys. If you need a flat roof survey at a property on Quad Road, Tower Lane and The Avenue or a nearby road, we can survey it. If you’re just outside Preston, we cover Wembley (1 mile south), Wembley Park (1 mile south-east), Kingsbury (1 mile north-east), Queensbury (1 mile north) and Mapesbury (1 mile south-east). Within a short drive, we also cover London (10 miles south-east), City of Westminster (7 miles south-east), Marylebone (7 miles south-east), Kensington (6 miles south-east), St Pancras (8 miles east) and Shoreditch (10 miles east).
Around Preston
We work in homes and buildings around Windermere pub, Preston Manor School and Preston Park. Preston’s nearest station is South Kenton station, roughly 0.6 miles west. A little further out are London Designer Outlet (1.1 miles south-east) and Kodak Museum (2.6 miles north-west). For a walk, there is Masons Field and Castlebar Hill.
Should I look at the roof myself first?
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. Don’t go up yourself.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
What affects the price in Preston
All our prices include VAT. What changes the price is:
- The package you choose: Basic, Standard or Premium
- House, block, shop or office
- The height of the building and how the roof can safely be seen
- Extra roofs, like extensions, dormers or garages
Prices quoted always include VAT, and the written report is part of the package. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Booking your survey
Here’s what helps us most when you get in touch:
- Dates you are working to, such as exchange

We survey roofs on weekdays and at weekends. To arrange a day that suits you, call 07833 053749 or send us an email with the address and the days you’d prefer.
FAQs for Preston
Does a conservation area affect roof work in Preston?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover commercial flat roofs around Preston?
Yes. As well as homes, we check flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Is Preston in your area?
Yes. We survey roofs across London and South East England, Preston included.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
How much does a flat roof survey cost in Preston?
Our price is from £150, including VAT. We confirm the price for your survey before you book, based on the roof’s size, access and package. To get a price, ring 07833 053749 or email us.
Do you test for asbestos?
No. Asbestos surveys and testing aren’t part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them.
What happens on the day
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey typically takes about 1–2 hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. In Preston, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- 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.
- Inside, we look for damp and staining under the roof where there is access.
- You get a report with photos and our recommendations.
Getting ready for the survey
- Find any records of previous roof work
- Have keys ready for side gates, garages or roof access doors
- Keep pets in another room

Roof by roof
Single-ply membranes
Single-ply membranes can be damaged by foot traffic and equipment on the roof. Any tears, punctures or loose membrane are recorded with photos.
Felt and built-up roofs
Many extensions, garages and dormers have a felt roof laid in layers. The survey checks for blisters, cracks, open laps and bare patches where the surfacing has worn.
Why get it checked now?
Before replacing a flat roof, it helps to know if you really need to. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. Any roof job in Preston means planning around parking, neighbours and access. That’s a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
Why us?
- Drone flown under a CAA Flyer ID and Operator ID
- Clear package prices, with VAT included
- 5,000+ roofs surveyed
- Visits on any day of the week

Do you need a flat roof survey in Preston?
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. Where they weren’t finished well, they tend to fail before anything else.
A survey makes sense if you’ve noticed:
- Raised blisters across the surface
- Gaps at upstands and abutments
- Failed seals around rooflight kerbs
- Loose or cracked edge trims
If you own a rental within reach of South Kenton station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- Whether the roof space is looked at, where there is one
- Whether VAT is in the quoted price
- How they plan to inspect the roof safely
- When you will get the report
