Flat Roof Survey in Broad Colney
Flat roof surveys in Broad Colney, with over 20 years’ experience behind it. You get a clear report with photos.
- Outlets choked with leaves and silt
- Damaged trims at the roof edge
- Signs of deflection in the roof deck
Before and after the survey
From years of surveys, a few habits stand out:
- Keep people off the roof unless they need to be there
- Never stand on rooflights or fragile sheeting
- Book a survey every few years
- Check from a window for ponding after heavy rain
Once we’ve been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.
How a flat roof survey works in Broad Colney
We inspect a flat roof from wherever it can safely be seen: from the roof itself where that’s safe, from windows and nearby vantage points, and from inside where there is access. Fragile rooflights and fragile sheets are never walked on. If part of the roof can’t be seen or reached safely, the report says so, so you know exactly what was covered. We survey single-ply membranes, mastic asphalt and upstands and outlets, and the problems we are asked to look at most are edge trims that have lifted or split and raised blisters across the surface.
In a village or hamlet like Broad Colney, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

The survey, step by step
The aim of the visit is simple: to see as much of the flat roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. The visit typically takes about one to two hours for most houses; commercial roofs usually need 3–4 hours. Somewhere like Broad Colney needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- 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.
Before we arrive
- Point out any leaks or damp patches
- Keep pets in another room
- Dig out any old roof reports or invoices

Advice
Flat roof surveys around Broad Colney
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. High Elms Manor, about 4.1 miles west, is one of the historic houses in the wider area around Broad Colney. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
The streets around a church like Church of St Peter are often among the oldest in a place, and if you own one of the older houses nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Park Street station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

FAQs for Broad Colney
Does a conservation area affect roof work in Broad Colney?

What we are asked to look at in Broad Colney
The surface of a flat roof heats up and cools down far more than the rooms below. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
These are some of the problems a survey can pick up:
- Dips that suggest the deck is deflecting
- Raised blisters across the surface
- Water getting in at rooflights
- Gaps at upstands and abutments
For site and facilities teams at buildings like Saint Bernadette Catholic Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before you book
- What the survey will not cover
- Their drone registration, if they fly one
- Their track record with similar roofs
- What follow-up you get after the report
Honest limits
To be straight with you, a roof survey has limits:
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
- A structural engineer’s assessment of the deck
- Hidden layers beneath the covering

Roofs we survey in Broad Colney
- Mastic asphalt
- Felt flat roofs
- GRP fibreglass

Roof by roof
EPDM rubber
A rubber roof can last 30 to 50 years, provided its details were done well. Those details are where we focus.
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. We note where this is happening and how widespread it looks.
