How a flat roof survey works in Longfield
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. The photographed record helps you plan and budget for work. Commercial roofs are quoted for their size and access, so please phone 07833 053749 or email us with the address and an idea of the roof’s size. We survey EPDM rubber, single-ply membranes and mastic asphalt, and the problems we’re asked to look at most are ponding water that doesn’t drain away and signs of deflection in the roof deck.
Somewhere as small as Longfield, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what is not.

What happens on the day
Every roof is different; as a rough guide, the survey takes between one and two hours for a small flat roof at home, and longer for a large commercial one. You’re welcome to ask questions while we are there. Somewhere like Longfield needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
Before the survey
- Clear the way to the loft hatch
- Find any records of previous roof work
- Have keys ready for side gates, garages or roof access doors

Common questions in Longfield
How do I find out if my home in Longfield is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Longfield?
Yes, Longfield is one of the places we work. The survey and report are the same in Longfield as anywhere else, and visits run on weekdays and weekends.
How much does a flat roof survey cost in Longfield?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it’s agreed before booking.
Are you structural engineers?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Will the survey show why my flat roof is leaking?
We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is looked at. Where nothing visible explains the leak, the report says what to try next.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
What will the report tell me?
Written findings with photographs, explaining the condition of the flat roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
When you need someone else
It is a careful look at the flat roof, not the whole story. Its limits include:
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- An exact number of years the roof has left
- Structural calculations, which need a structural engineer

Local flat roofs in Longfield
About 4 miles east lies Cobham College, a reminder of how long the area around Longfield has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For businesses in and around places such as Bluewater, flat roofs over shops and units are easy to forget until water comes through a ceiling. For site and facilities teams at buildings such as Longfield Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Longfield station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

How the survey changes by roof type
EPDM rubber
Rubber roofs can shrink back from their edges or lift where the adhesive has failed. We record any we can see, with photographs.
GRP fibreglass
A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. The survey checks for cracking at board joints, at the edge trims and where the roof meets walls.
