Flat roof survey in Park Royal: what you get
Every flat roof covering tends to fail in its own way. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’re worried about loose or cracked edge trims and ponding water that doesn’t drain away, a survey will tell you what’s going on, whatever the roof.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Park Royal, the roof above may belong to the building rather than one flat.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Common roof problems in Park Royal
Flat roofs swing between hot and cold more than most parts of a building. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
Things that frequently lead to a survey include:
- Signs of deflection in the roof deck
- Damaged trims at the roof edge
- Cracked or split membrane
- Upstands pulling away from walls
Shop and office owners around London Designer Outlet may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
Before booking any roof surveyor
- Whether the inside of the roof is included
- Whether you can ask questions once you have the report
- Their report turnaround times
- Will the report include photos?
For landlords and managing agents
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
What a flat roof survey does not cover
It’s useful to know what a survey will not do before you book:
- What’s under the membrane without opening it up
- Whether the deck or joists are strong enough
- Fragile surfaces, which we do not walk on

Flat roof surveys around Park Royal
Park Royal has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.

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 a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings like West Twyford Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Your questions about flat roof surveys in Park Royal
Do you cover commercial flat roofs around Park Royal?
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.
Can parking be tricky for a visit in Park Royal?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Will you photograph what you find?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Can you survey in bad weather?
It can, depending on the survey. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
Do you need to get into the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Do you work in Park Royal?
Yes. We survey roofs across London and South East England, Park Royal included.
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London area like Park Royal, the main things to sort out are parking and access: tell us 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 agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from ground level, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Getting ready for the survey
- Keep pets out of the way during the survey
- Show us where any leaks or stains appear
- Have any paperwork from past roof work to hand
Arrange a survey
When you’re ready to go ahead, phone 07833 053749 or drop us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
Advice
Roof by roof
Felt and built-up roofs
The edges and upstands of a felt roof are normally where trouble starts. We check each one and photograph any that have split or pulled away.
GRP fibreglass
A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. We look for cracks at board joints, around trims and at upstands.
