Flat roof survey in Colliers End, Hertfordshire

Roof by roof
EPDM rubber
A rubber roof can last 30 to 50 years, provided its details were done well. We look closely at each of those details.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.
Flat roof survey in Colliers End
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. You then have something specific to put to the seller or agent. If you’ve noticed blocked or damaged outlets and a sagging deck under the covering, a survey will tell you what’s going on, whatever the roof.
In a small place like Colliers End, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

What we do, step by step
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes between one and two hours for a small flat roof at home, and longer for a large commercial one. Around Colliers End, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from ground level, windows and the roof where it is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Before we arrive
- Make a note of anything you’d like us to look at
- If you are buying, check with the agent that we can get in
- For a flat or shared roof, check access with whoever owns or manages the building

What a flat roof survey does not cover

- Testing older roof sheets for asbestos
- Hidden layers beneath the covering
If in doubt, phone 07833 053749 or drop us an email and we’ll suggest the right survey. What a survey covers and does not.

Flat roof surveys in Colliers End: local notes
Much Hadham Palace, about 3.7 miles east, is one of the historic houses in the wider area around Colliers End. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you let a flat or house near Ware station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take an older house close to St Mary's: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you look after a building such as Ralph Sadleir Middle School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Colliers End questions
Is Colliers End in the area you cover?
Yes, Colliers End is one of the places we work. Every survey there gets the same written report with photos.
Is Colliers End within the area you cover?
Yes, we do. We survey roofs across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Which flat roof coverings do you cover?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. If you don’t know what your roof is, we will identify it on the day.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Is a flat roof survey the same as a building survey?
No. It’s a closer look at the flat roof, not a survey of the whole property. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
Will the survey show why my flat roof is leaking?
Our survey looks across the whole roof, not only above the stain. Every split, lap, upstand, outlet and rooflight we can see is looked at. If the cause cannot be seen, we will say so and suggest what would help.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Practical tips
There is plenty you can do without going near the roof. Here’s what helps most:
- Treat rooflights and old sheeting as fragile
- Note the date and type of any roof work
- Note any new marks on ceilings beneath the roof
- Book a survey every few years
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on.
