About our flat roof survey in Colindale
Offices, shops, industrial units and blocks of flats frequently sit under large flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. The photographed record helps you plan and budget for work. We quote commercial roofs on their size and how they’re reached, so it helps if you call 07833 053749 or drop us an email with the address and a rough idea of the roof area. We survey single-ply membranes, mastic asphalt and EPDM rubber, and the problems we’re asked to look at most are water getting in at rooflights and outlets choked with leaves and silt.
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, each with its own weak points. Which one is on a roof in Colindale shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

What we’re asked to look at in Colindale
Water that doesn’t drain sits on the roof and speeds up wear. It normally comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
These are some of the problems a survey can pick up:
- Cracked or split membrane
- Failed seals around rooflight kerbs
- Outlets choked with leaves and silt
- Damaged trims at the roof edge
As a London address, Colindale can be tricky for parking: let us know about permits, visitor bays or off-street space when booking.

What a flat roof survey looks like in Colindale
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. 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. Heath Hall, about 3.5 miles east, is one of the historic houses in the wider area around Colindale. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you let a flat or house near Hendon station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as Colindale Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Colindale is about 1 mile south-east of Burnt Oak, in Greater London. If you are in Colindale, booking works exactly as it does anywhere else: a call or an email, a price, then a date. We cover towns and villages across Greater London, large and small. You can also see our page for London.

Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
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.
What happens on the day
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes roughly 1–2 hours at most homes, or half a day or so for a commercial building. In a London area like Colindale, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it is safe.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from ground level, from windows and from the roof where it’s safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- The findings are written up with photos and recommendations and emailed to you.
Getting ready for the survey
- Have any paperwork from past roof work to hand

Common questions in Colindale
Will parking be an issue for a roof survey in Colindale?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Is Colindale in the area you cover?
Yes. We cover the whole of London and South East England, and Colindale is part of that. You can ring 07833 053749 or drop us an email with the address and some details.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
How long is the visit?
Time on site depends on the roof; most visits take roughly 1–2 hours at most homes, with bigger or more complicated roofs taking longer. The written report follows by email.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
How do you inspect a flat roof?
We inspect from wherever is safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.

Why act early in Colindale
A small split in a flat roof is usually a modest job when it’s found early. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. A survey now shows which you are dealing with. In Colindale, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
Flat roof survey starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we’ll tell you which fits.

What we cannot see

- Structural calculations, which need a structural engineer
- Asbestos testing, which needs a specialist asbestos surveyor
- Parts of the roof that aren’t safe to walk on or view
