About our flat roof survey in Park Street
Flat roofs deal with rain in a very different way from pitched ones. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. We check the surface, the falls, the upstands and the edge trims, and we note any sign that the deck below has got wet. That way, defects are found before they reach the room below. We survey single-ply membranes, EPDM rubber and felt flat roofs, and the problems we’re asked to look at most are edge trims that have lifted or split and a sagging deck under the covering.
Flat roofs on exposed homes in small places like Park Street take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photo. You will see the good as well as the bad.

Your questions about flat roof surveys in Park Street
Do you cover smaller places like Park Street?
Yes. Park Street is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Park Street in the area you cover?
Yes, Park Street is within the area we cover. We work right across London and South East England. You can call 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
Can you tell me how long my flat roof will last?
A precise figure is not something we give, because it depends on upkeep, weather and how the roof was laid. We describe the condition and say which work is urgent and which can wait.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It often means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. Our survey notes the ponding and what seems to be causing it.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so the building owner or managing agent needs to agree access. We can only inspect what we are given access to.
What types of flat roof do you survey?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you don’t know what your roof is, we’ll identify it on the day.
Is a flat roof survey the same as a building survey?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
What this survey can’t tell you
Every survey has limits, and we’d rather be clear about that before you book. Bear these in mind:
- A structural engineer’s assessment of the deck
- A fixed date for when the roof will need replacing
- Whether old sheeting or boards contain asbestos

What this survey covers
- Upstands and outlets
- GRP fibreglass
- Single-ply membranes
- Mastic asphalt
- EPDM rubber
- Felt flat roofs
How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes between one and two hours at most homes, rising to roughly 3–4 hours on a commercial building. For a village or hamlet like Park Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can be seen safely, inside and out.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from ground level, from windows and from the roof where it is safe to do so.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- The findings are written up with photographs and recommendations and emailed to you.
How to prepare
- Make a note of anything you’d like us to look at
- Dig out any old roof reports or invoices
- If the roof is shared, arrange access with whoever manages the building
How to book
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.

Flat roof surveys around Park Street
Historic houses such as High Elms Manor, about 2.7 miles south-west, show how far back building in the area around Park Street goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Anyone responsible for a site like Park Street Church of England Voluntary Aided Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you run a business near Village Arcade St Albans, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Park Street is about 2 miles south of St Albans, in Hertfordshire. Surveys in Park Street work the same way as everywhere we cover: a careful inspection, photos and a written report. Our area takes in places right across Hertfordshire. You can also see our page for London.

What’s near Park Street

What we are asked to look at in Park Street
Ponding keeps the covering wet and wears it faster. It typically comes from poor falls, a blocked outlet or a deck that has dipped. Leaves and silt from nearby trees can soon choke an outlet.
A survey can pick up problems such as:
- Blocked or damaged outlets
- A sagging deck under the covering
- Leaks around rooflights
- Pools of water lying on the roof
For landlords with property near Park Street station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Questions to ask before booking
- Their insurance cover
- What follow-up you get after the report
- Whether you get a written report with photos
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What you can safely check yourself
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
Leave it or get it looked at?
A leak over an office, shop or unit can affect the people and stock underneath. A planned survey lets you budget for work rather than deal with an emergency around the people who use the building. In a place like Park Street, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.

Roof by roof
Felt and built-up roofs
The edges and upstands of a felt roof are usually where trouble starts. We check each one and photograph any that have split or pulled away.
EPDM rubber
EPDM often lasts 30 to 50 years, but it relies on its seams, trims and upstands being well finished. Those details are where we focus.
