Flat roof survey in Haldens
Every flat roof covering tends to fail in its own way. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. We survey EPDM rubber, felt flat roofs and single-ply membranes, and the problems we are asked to look at most are loose or cracked edge trims and pools of water lying on the roof.
In smaller places like Haldens, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What happens on the day
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. In a smaller place like Haldens, parking is seldom the issue; lanes, gates and long drives are worth mentioning. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
Preparing for the visit
- Have any paperwork from past roof work to hand
- If it is not your property yet, arrange access through the agent

What else we do in Haldens
Different roofs, different checks
Felt and built-up roofs
Many extensions, garages and dormers have a felt roof laid in layers. We look for blistering, cracking, split laps and worn mineral surfacing.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
Signs you need a flat roof survey in Haldens
Flat roofs often get walked on for other jobs: to clean windows, fit aerials or air conditioning units, or reach a gutter. A covering that wasn’t designed for foot traffic can crack or puncture. New brackets and fixings through the roof are another common source of leaks.
Common reasons to book include:
- Ponding water that doesn’t drain away
- Dips that suggest the deck is deflecting
- Edge trims that have lifted or split
- Leaks around rooflights
Anyone responsible for a site like Waterside Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

When you need someone else
Before booking, it is worth knowing what a survey will not do:
- A structural engineer’s assessment of the deck
- Asbestos testing, which needs a specialist asbestos surveyor
- A fixed date for when the roof will need replacing

Haldens: your questions answered
Is my home in Haldens listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.

Yes, Haldens is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and some details, and we’ll talk through which survey suits.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
How fast do I get the report?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.

It typically takes about 1–2 hours for most houses, and about three to four hours for a commercial roof. You’ll then get the report by email.
Will you check the loft?
If there’s a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To arrange a date, phone 07833 053749 or send us an email.
What a survey costs
The price reflects the time and kit the roof needs. The main factors are:
- The shape of the roof and its details
- How tall the building is and how easy the roof is to see
- Which survey package you book
- How many separate roofs there are, such as extensions, dormers and garages
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.
Booking your survey
We’ll normally ask about:
- Whether there’s a loft hatch, a shared roof or tricky access
- Your timetable, such as an exchange date
- Why you want a survey: buying, a leak, a storm or new work
- What kind of property and roof it is
Every survey is priced before it’s booked, so you know where you stand. Our price is from £150, including VAT. To book, call 07833 053749 or send us an email.

Flat roof surveys around Haldens
