About our flat roof survey in Westwick Row
Many commercial buildings and blocks of flats have big flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photos so work can be planned and budgeted. We quote commercial roofs on their size and how they’re reached, so please phone 07833 053749 or email us with the address and an idea of the roof’s size. We survey upstands and outlets, single-ply membranes and EPDM rubber, and people most often book us about cracked or split membrane and blistering in felt or asphalt.
In a small place like Westwick Row, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to.

What this survey can’t tell you
It’s a careful look at the flat roof, not the whole story. The main limits are:
- Structural calculations, which need a structural engineer
- Hidden layers beneath the covering
- An exact number of years the roof has left
If you’re not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer. The full list of what we check.

Why get it checked now?
Flat roofs can’t normally be seen from the street, so they’re often overlooked. Owners often learn the roof is at the end of its life only when it leaks. A survey every few years stops that from catching you out. Where a roof is exposed, as many are in small places like Westwick Row, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
All our prices include VAT. Prices start from £150, including VAT. You will know the price for your survey before booking.

Your questions about flat roof surveys in Westwick Row
Is my home in Westwick Row listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is Westwick Row within the area you cover?
Yes, we do. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Does the survey cover asbestos?
We don’t carry out asbestos surveys. Buildings built or refurbished before 2000 may contain asbestos, for example in cement roof sheets. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
How experienced are you?
More than 5,000 surveys over 20+ years, across London and South East England.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
What a flat roof survey looks like in Westwick Row
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Westwick Row is part of Hemel Hempstead, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Many of those flat roofs have been re-covered over the years, and some may still have older felt.
Take an older house close to Church of Holy Trinity: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a building such as Leverstock Green Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Westwick Row is about 2 miles east of Hemel Hempstead, in Hertfordshire. We carry out flat roof surveys for homes and businesses in Westwick Row and nearby. Westwick Row is one of the places in Hertfordshire where we work. For surveys nearby, see our London page.

Common roof problems in Westwick Row
Ponding keeps the covering wet and wears it faster. Blocked outlets, poor falls and a sagging deck are the usual causes. Leaves and silt from nearby trees can soon choke an outlet.
A survey makes sense if you’ve noticed:
- Blisters and bubbles in the covering
- Loose or cracked edge trims
- Failed seals around rooflight kerbs
- Standing water left after rain
With Batchwood Hall about 3.1 miles north-east, the area around Westwick Row has a long history. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.
Before booking any roof surveyor
- Whether the price includes VAT
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What happens after the report arrives
- Will they check the loft as well as the outside?
Tips from our surveys
Over many surveys, some simple habits stand out as worth the effort:
- Keep clear of rooflights and fragile roof sheets
- Check that new brackets or units haven’t damaged the covering
- Keep outlets clear of leaves and moss
- Look for standing water a day after rain
If anything in the report is not clear, just ask us. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, so you can talk the findings through.
Small defects are simpler to deal with while they’re still small. A flat roof that is looked after between surveys typically lasts longer.
What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will take it from there. A typical survey takes about one to two hours for a small flat roof at home, and longer for a large commercial one. Around Westwick Row, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We check the roof from the ground, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Before the survey
- Tell us where we can park nearby
- Unlock side gates and any roof access doors
- Make sure the loft hatch can be reached
