Questions from Bull's Green
Does a conservation area affect roof work in Bull's Green?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you cover Bull's Green?
Yes. We survey roofs across London and South East England, and Bull's Green is part of that. You can ring 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Can you tell me how long my flat roof will last?
We do not give a fixed number of years, because so much depends on upkeep, exposure and workmanship. We describe the condition and say which work is urgent and which can wait.
How much is a survey?
Flat roof survey starts from £150, including VAT. The final figure depends on the roof and the package you choose, and it is agreed before booking.
I live in a flat. Can you survey the roof?
Yes, if whoever owns or manages the building agrees access. We look at the parts we’re given access to.
Does the weather affect the survey?
Light rain is usually fine; heavy rain and wind are different. High wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
About our flat roof survey in Bull's Green
Every flat roof covering tends to fail in its own way. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the 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. If you are worried about blocked or damaged outlets and dips that suggest the deck is deflecting, a survey will tell you what’s going on, whatever the roof.
Flat roofs on exposed homes in small places like Bull's Green take more wind and rain, 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.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Why get it checked now?
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, while there’s still time to plan the work. For older village homes like those around Bull's Green, the right replacement materials are not always easy to find quickly. That’s one more reason to find defects before they become urgent.
Prices quoted always include VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

How the survey changes by roof type
EPDM rubber
A rubber roof can last 30 to 50 years, provided its details were done well. Those details are where we focus.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.
Tips from our surveys
You do not need to be a roofer to help. Here’s what helps most:
- Ask whoever fits equipment on the roof to make good the covering
- Never stand on rooflights or fragile sheeting
- Check ceilings under the roof for damp patches
- Plan a survey before the covering reaches the end of its usual life
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. It’s written in plain English, with a photo of each defect, so anyone reading it can see what we saw.
Try not to let a flat roof become a walkway. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
Flat roofs in Bull's Green
The wider area around Bull's Green has a long history of building, with Digswell House about 2.6 miles south-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Shop and office owners around Howard Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. For landlords with property near Welwyn North station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. Most surveys take between one and two hours for a small flat roof at home, and longer for a large commercial one. Older roofs in small places like Bull's Green can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it’s safe.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from ground level, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.

DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
