What we are asked to look at in St Mary Cray
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
A survey can pick up problems like:
- Outlets choked with leaves and silt
- Gaps at upstands and abutments
- Failed seals around rooflight kerbs
- Loose or cracked edge trims
If you own a rental within reach of St Mary Cray station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

How a flat roof survey works in St Mary Cray
A flat roof leak frequently travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. Our survey covers the whole roof, not just the part above the mark, with photos of anything that could be letting water in. Whoever carries out the work then has a clear starting point. If you are worried about leaks around rooflights and damaged trims at the roof edge, a survey will tell you what’s going on, on felt flat roofs, upstands and outlets and GRP fibreglass alike.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In St Mary Cray, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. It records what’s sound as well as what isn’t.

Roof by roof
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We check for splits, gaps and loose flashings above the upstand.
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.
Flat roof surveys in St Mary Cray: local notes
About 3.8 miles west lies Bromley Palace, a reminder of how long the area around St Mary Cray has been built on. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Church of St Mary: the joins between later flat roofs and the old walls are where problems typically start. If you look after a building like Poverest Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

FAQs for St Mary Cray
Can parking be tricky for a visit in St Mary Cray?
It can be, so it’s useful to let us know about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
Do you cover St Mary Cray?
Yes. Our area covers London and the South East, and St Mary Cray is part of that. Just call 07833 053749 or send us an email and let us know about the property.
How do you inspect a flat roof?
Where it’s safe, the roof is inspected from the roof itself. Otherwise we use windows, vantage points and the spaces below, and the report says if any part couldn’t be seen. Fragile surfaces are never walked on.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
Should I worry about standing water on my flat roof?
Water that lies on a flat roof for days is a sign that something needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
What if it rains on the day?
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.
What happens on the day
Once we’ve finished looking, we write up our findings as a report with photographs, sent to you by email. On timing, it normally takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. In a London area like St Mary Cray, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can safely be seen from the ground, windows, the loft and, where it’s safe, the roof itself.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
How to prepare
- Have any questions written down, so nothing gets missed
- Tell us about any leaks, stains or damp patches you know of
- Leave a clear route to the loft
How to book
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or drop us an email.
Advice
When you need someone else
In fairness, a roof survey has limits:
