Flat roofs
Flat roof survey by drone — see the whole surface in one go
You cannot judge a flat roof from the edge of a ladder. Our drone photographs the entire surface from above, so ponding, splits, blisters, failed seams and blocked outlets are all visible in one set of dated images — each defect circled and graded in your report. Fixed £99 for residential, £149 for commercial.

Flat roof defects we photograph
Ponding water
Standing water after rain points to falls that are too shallow or a sagging deck, and it shortens the life of any covering.
Splits and cracks
Felt hardens and splits with age and temperature swings — usually at upstands and corners first.
Blistering and lifting
Trapped moisture beneath the membrane bubbles up and eventually tears.
Failed seams and laps
Where sheets overlap is where water gets in first, especially on older torch-on felt.
Upstand and flashing defects
Where the flat roof meets a wall, parapet or door threshold is the most common leak point.
Blocked outlets and gutters
Leaves and moss block rainwater outlets, and the water has nowhere to go but inwards.

Flat roof survey questions
Can you survey a flat roof with a drone?
Flat roofs are the ideal drone job. From above you see the entire surface at once — ponding, splits, blisters, seams and outlets — which is far more useful than the partial view you get from a ladder at the edge.
What does a flat roof survey cost?
A residential flat roof survey is £99 and commercial premises are £149, fixed price with the annotated report included and no access equipment to hire.
Do you survey felt, GRP, EPDM and single-ply?
Yes. The photographic survey works on any covering — torch-on felt, GRP fibreglass, EPDM rubber, single-ply membrane, asphalt and liquid systems. The report describes what we can see and how serious each defect is.
How long does a flat roof last?
As a rough guide, older built-up felt often lasts 10–20 years, GRP and EPDM commonly 20–30 years, and single-ply systems similar, depending on install quality, falls and maintenance. A photographic survey tells you where yours is in that life.
Can you survey a commercial or industrial flat roof?
Yes. Commercial premises are £149 and we cover warehouse, retail and office roofs across G, ML and EH postcodes. Large sites can be quoted individually — get in touch with the address and rough footprint.
