Your questions about flat roof surveys in Lea Valley
Is my home in Lea Valley listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you come out to Lea Valley?
Yes, Lea Valley is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Can you survey any kind of flat roof?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
How do I arrange a flat roof survey in Lea Valley?
To arrange a survey, phone 07833 053749 or email us and tell us the address and what you need to know. We’ll confirm the price and agree a day with you.
How much is a survey?
Flat roof survey starts from £150, including VAT. We confirm the price for the job before you book, based on the roof’s size, access and package. To get a price, ring 07833 053749 or drop us an email.
How many years has my flat roof got left?
We don’t put a figure on it. As a guide, felt often lasts around 15 to 20 years, EPDM often 30 to 50 and GRP up to about 30, but the report tells you how your roof is really doing.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Flat roof survey in Lea Valley: what you get
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. You get a report with photographs and our recommendations. We survey felt flat roofs, upstands and outlets and single-ply membranes, and the problems we’re asked to look at most are standing water left after rain and dips that suggest the deck is deflecting.
In a small place like Lea Valley, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Flat roof surveys in Lea Valley: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, 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. Shaw's Corner, about 2.5 miles north-east, is one of the historic houses in the wider area around Lea Valley. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
Take a building like High Beeches Primary School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Harpenden station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

Common roof problems in Lea Valley
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
Here are some of the things we see frequently:
- Signs of deflection in the roof deck
- Cracked or split membrane
- Loose or cracked edge trims
- Upstands pulling away from walls
If yours is one of the older homes in the streets near All Saints, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

DIY checks: what’s safe
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. Don’t go up yourself.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
How it works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about 1–2 hours on an ordinary house; commercial roofs usually need 3–4 hours. If you have questions on the day, just ask. For a village or hamlet like Lea Valley, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We check the roof from wherever it can be seen safely.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- Where there’s safe access, we check the ceilings and spaces below for signs of water.
- The findings are written up with photos and recommendations and emailed to you.
Before we arrive
- Mention any parking restrictions on your street
- If the roof is shared, arrange access with whoever manages the building
- Keep pets in another room
