Flat roof survey in Kemprow: what you get
Each flat roof is looked at from the safest viewpoints we have: from the roof itself where that is safe, from windows and nearby vantage points, and from inside where there’s access. We don’t walk on fragile rooflights or fragile roof sheeting. Where any area can’t be viewed safely, we say so in the report, so the limits of the survey are clear. We survey mastic asphalt, EPDM rubber and upstands and outlets, and people most frequently book us about cracked or split membrane and gaps at upstands and abutments.
Some older homes in villages like Kemprow are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

DIY checks: what’s safe
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey.
Kemprow: your questions answered
Is my home in Kemprow listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Will you come out to Kemprow?
We do. A small place gets exactly the same survey as a big one.
Do you cover flat roofs on blocks of flats?
Yes. Commercial and residential flat roofs are both covered. A commercial roof typically takes about 3 to 4 hours on site, longer if it is large or complex, and larger roofs are quoted for their size.
Do you survey on Saturdays and Sundays?
We carry out surveys on any day of the week. To arrange a date, call 07833 053749 or use the contact form.
How long is the visit?
Time on site depends on the roof; most visits take between one and two hours for a small flat roof at home, and longer for a large commercial one. The written report follows by email.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
Leave it or get it looked at?
Most flat roofs are out of sight, so they’re easy to forget. Many owners only find out a roof is worn out when water comes through. A survey every few years stops that from catching you out. In a small place like Kemprow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every price we give includes VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Size, height and access decide where your roof falls.

Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep records of when the roof was laid and what work has been done
- Limit foot traffic on the covering
- Have the roof looked at again after a severe storm
- Keep clear of rooflights and fragile roof sheets
After the visit, we write up the report with photographs of what we found. 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.
Keep outlets, gutters and hoppers clear, particularly after the leaves fall. Water that can drain away does far less harm than water that sits.
How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about one to two hours for a small flat roof at home, and longer for a large commercial one. If you have questions on the day, just ask. Older roofs in small places like Kemprow can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there’s access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- Have any paperwork from past roof work to hand
- Leave side gates unlocked
- Agree roof access with the managing agent if it’s shared
Getting a price
Getting a price is simple: just phone 07833 053749 or email us and give us some details about the property and we’ll recommend the right survey. The price is agreed up front.

Flat roof surveys around Kemprow
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. High Elms Manor, about 2.7 miles north-west, is one of the historic houses in the wider area around Kemprow. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
For landlords with property near Radlett station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you run a business near Harlequin Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Kemprow is about 3 miles north of Bushey, in Hertfordshire. Whether the building in Kemprow is a house, a flat or a commercial unit, the roof can be surveyed. Our area takes in places right across Hertfordshire. London is in our area too.

How the survey changes by roof type
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. We record any we can see, with photographs.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
Do you need a flat roof survey in Kemprow?
Flat roofs swing between hot and cold more than most parts of a building. This constant movement works at laps, seams and board joints, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.
A survey can pick up problems like:
- Damaged trims at the roof edge
- Blisters and bubbles in the covering
- Signs of deflection in the roof deck
- Splits, cracks and crazing
Take an older house close to St John: the joins between later flat roofs and the old walls are where problems normally start.
