Flat roof survey in Redbourn: what you get
Every flat roof covering tends to fail in its own way. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. Common reasons to book are damaged trims at the roof edge and upstands pulling away from walls, on felt flat roofs, upstands and outlets and GRP fibreglass.
Around a smaller place like Redbourn, flat roofs typically cover extensions, garages and dormers. Even a small flat roof can let plenty of water into the room below. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

FAQs for Redbourn
How do I find out if my home in Redbourn 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.
Is Redbourn in the area you cover?
Yes, Redbourn is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
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 water that sits wears the covering sooner. Our survey notes the ponding and what seems to be causing it.
Can you survey a flat roof on an office or unit?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
Do you take photos of the roof?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
Are you insured?
Our cover is professional indemnity plus public liability.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know as you book.
How we price flat roof surveys
Not every roof costs the same to survey, and it comes down to:
- Whether you choose the Basic, Standard or Premium Survey
- Chimneys, valleys, parapets and other details
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
Prices quoted always include VAT, and the written report is part of the package. Flat roof survey starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Helping us price your survey
Some details help us suggest the right survey and price. When you contact us, tell us:
- Any deadline, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- The address and postcode of the property
- Any marks or damp showing indoors
We confirm the price for your roof before you book, so you know where you stand. Prices start from £150, including VAT. For a price for your roof, ring 07833 053749 or drop us an email.
What this survey can’t tell you
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- Whether old sheeting or boards contain asbestos
- Hidden layers beneath the covering
- Areas we can’t see or reach safely, including fragile rooflights and sheeting

What a flat roof survey looks like in Redbourn
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Childwickbury Manor, about 2.6 miles south-east, is one of the historic houses in the wider area around Redbourn. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For landlords with property near Harpenden station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Redbourn Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you live in an older home near Mount Zion Evangelical Church, flat-roofed rear additions and dormers added over the years are worth checking.
Redbourn is about 2 miles south-west of Harpenden, in Hertfordshire. Roofs in Redbourn get the same thorough look as anywhere else in Hertfordshire. We cover towns and villages across Hertfordshire, from the larger towns to small villages. There is also a page for Milton Keynes.

The survey, step by step
Every roof is different; as a rough guide, the survey takes between one and two hours on an ordinary house, and about three to four hours for a commercial roof. You’re welcome to ask questions while we are there. A visit to a smaller place like Redbourn is no different on the day: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
How to prepare
- Clear the way to the loft hatch
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed
How to book
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or send us an email when you’re ready.

Before and after the survey
There’s plenty you can do without going near the roof. Here’s what helps most:
- Check ceilings under the roof for damp patches
- Never stand on rooflights or fragile sheeting
- Keep people off the roof unless they need to be there
- Have the roof looked at again after a severe storm
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. Each defect is described in plain words and shown in a photo, so anyone reading it can see what we saw.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
Why act early in Redbourn
A small split in a flat roof is usually a modest job when it is found early. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Around Redbourn, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
