Flat Roof Survey in Ley Green
Know where you stand with the flat roof before you decide what to do next. We carry out flat roof surveys in Ley Green, with photographs and a clear written report.
- Ponding water that does not drain away
- Failed seals around rooflight kerbs
- Edge trims that have lifted or split
When you need someone else
Some things can’t be seen without opening up the roof, so a survey has limits:
- Asbestos testing, which needs a specialist asbestos surveyor
- Parts of the roof that are not safe to walk on or view
- Whether the deck or joists are strong enough

Flat roof surveys for homes and businesses in Ley Green
Buying a home with a flat-roofed extension, dormer or garage? It is useful to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. Our report records the covering, how it’s holding up and any defects we can see, with photos of each. That gives you facts to raise with the seller or agent. We survey single-ply membranes, GRP fibreglass and EPDM rubber, and the problems we’re asked to look at most are raised blisters across the surface and gaps at upstands and abutments.
Older buildings in small places like Ley Green may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
After the visit, you get a photo-illustrated written report, sent by email. It sets out the condition of the flat roof, any defects and our written recommendations.

What else we do in Ley Green
What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
Flat roofs in Ley Green
About 4.9 miles south-east lies Knebworth House, a reminder of how long the area around Ley Green has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you live in an older home near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. Landlords with a home close to Hitchin station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as Preston Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Ley Green is about 4 miles south-west of Hitchin, in Hertfordshire. Bookings from Ley Green are handled just like any other: a call or an email, a price, then a date. Ley Green is one of the places in Hertfordshire we cover for flat roof surveys. Milton Keynes is in our area too.
Flat roof surveys in SG4 work the same way as everywhere else we cover. If you need a flat roof survey at a property on Plough Lane, Whitehall Road and School Lane or a nearby road, we can survey it. Close by, we survey roofs in Great Offley (2 miles north-west), Temple End (2 miles north) and The Flints (2 miles north-west). Further out, we also cover Hemel Hempstead (12 miles south-west), Stevenage (6 miles east), St Albans (11 miles south), Welwyn Garden City (9 miles south-east), Harpenden (6 miles south) and Hitchin (4 miles north-east).
Around Ley Green
For rail, the closest station is Hitchin station, about 4 miles north-east of the centre. Well-known places in the area include Wymondley Castle (4.3 miles north-east) and Lister Hospital (4.5 miles east). For a walk, there’s Markham's Hill and Oughtonhead Nature Reserve.
What happens on the day
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes roughly 1–2 hours at a typical home, or half a day or so for a commercial building. Cottages and farmhouses around Ley Green frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We view the roof from ground level, from windows and from the roof where it’s safe to do so.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there’s safe access, we check the ceilings and spaces below for signs of water.
- The findings are written up with photographs and recommendations and emailed to you.
Before the survey
- Have any paperwork from past roof work to hand
- Clear the way to the loft hatch
- Unlock side gates and any roof access doors

Your questions about flat roof surveys in Ley Green
Is Ley Green within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you cover Ley Green?
Yes, Ley Green is one of the places we work. The survey and report are the same in Ley Green as anywhere else.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
What do I do with the report?
The report arrives by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
How do I book a survey in Ley Green?
Just call 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Treat rooflights and old sheeting as fragile
- Note where water lies after a downpour
- Keep outlets clear of leaves and moss
- File the paperwork for the roof and any repairs
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, giving you a chance to go through what we found.
Try not to let a flat roof become a walkway. Where someone does need access, ask them to use boards or a protected route, and remind them never to step on rooflights or fragile sheets.
Roof by roof
Rooflights and upstands
Rooflights and fragile sheets are never walked on. They’re inspected from safe positions and recorded with photos.
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.
