Flat roof survey in Harpenden: what you get
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. Typical surveys look at blocked or damaged outlets and blisters and bubbles in the covering, across GRP fibreglass, single-ply membranes and felt flat roofs.
In a town like Harpenden, plenty of shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile. A survey, or electronic testing where the membrane suits it, shows what’s going on. If someone else manages the building, let us know so roof access can be arranged.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

What happens if roof problems are left?
A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes some details are to blame, and sometimes the covering has simply had its day. The report sets out what we found, so you can make that decision with a roofer. Once water reaches the loft insulation in a home in Harpenden, it loses much of its value and is slow to dry. That adds to the bill long before the leak is obvious.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.
Why us?
- Professional indemnity and public liability insurance
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID

DIY checks: what’s safe
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.

Flat and commercial roofs around Harpenden
About 2.6 miles south lies Childwickbury Manor, a reminder of how long the area around Harpenden has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you live in an older home near St Nicholas Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Take a building like Harpenden Academy: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For landlords with property near Harpenden station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Roof by roof
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. We record any cracking and any signs of the deck moving.
Rooflights and upstands
Rooflights and fragile sheets are never walked on. We view them from safe positions and photograph what we see.
Practical tips
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Book a survey every few years
- Keep people off the roof unless they need to be there
- Clear roof outlets and gutters each autumn
- Treat rooflights and old sheeting as fragile
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. Each defect is described in plain words and shown in a photo, so anyone reading it can see what we saw.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.

Questions from Harpenden
What do I need to do before a survey in Harpenden?
Mostly, it’s about access: the loft hatch, any locked gates and where to park in Harpenden. It also helps to know about any leaks or earlier repairs.
Is Harpenden in the area you cover?
Yes, Harpenden is within the area we cover. We work right across London and the South East. Just ring 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.

Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days as you book.
Will you photograph what you find?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
Will you check the loft?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.

Just ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.
How it works
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take roughly 1–2 hours for a house, while a commercial roof takes nearer three to four hours. Parking in a town like Harpenden is normally simple, but tell us if there is a driveway or any restrictions. The inspection covers what can safely be seen from outside, from windows and from the loft space.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- 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.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Clear the way to the loft hatch
- Keep pets in another room
