Flat roofs in Letty Green
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. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Hatfield House, about 3.4 miles south-west, is one of the historic houses in the wider area around Letty Green. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you live in an older home near St John's Church, the flat roofs on later extensions tend to wear out long before the main roof. For businesses in and around places like Howard Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Letty Green is about 3 miles south-east of Welwyn Garden City, in Hertfordshire. If you are in Letty Green, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day.

Flat roof survey in Letty Green: what you get
We inspect a flat roof from wherever it can safely be seen: on the roof where it’s safe, from windows and higher ground, and from the rooms below where we can reach them. We do not walk on fragile rooflights or fragile roof sheeting. If part of the roof can’t be seen or reached safely, the report says so, so the limits of the survey are clear. Typical surveys look at blocked or damaged outlets and upstands pulling away from walls, across GRP fibreglass, single-ply membranes and mastic asphalt.
Somewhere as small as Letty Green, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report records the flat roof as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

Letty Green questions
Does a conservation area affect roof work in Letty Green?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you cover Letty Green?
Yes, Letty Green is within the area we cover. We work right across London and South East England. You can call 07833 053749 or drop us an email with the address and a few details.
How do I arrange a flat roof survey in Letty Green?
Simply call 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
What happens next?
You will get the report by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Can you survey in bad weather?
Light rain is typically fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
The survey, step by step
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take between one and two hours for a small flat roof at home, and longer for a large commercial one. Cottages and farmhouses around Letty Green frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is 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.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Keep pets in another room
- If it isn’t your property yet, arrange access through the agent
Getting a price
When you’re ready to go ahead, ring 07833 053749 or drop us an email. We will suggest a package, agree the price and find a date, weekday or weekend.
Related advice
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
When to book a survey in Letty Green
The details are often where a flat roof lets go first. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. If they were rushed when the roof was laid, they’re often the first things to fail.
Common reasons to book include:
- Outlets choked with leaves and silt
- Upstands pulling away from walls
- Loose or cracked edge trims
- Blistering in felt or asphalt
Landlords with a home close to Hertford North station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
What to check before booking
- Will the report include photos?
- Will they check the loft as well as the outside?
- Their report turnaround times
- What they won’t be able to tell you
How we price flat roof surveys
We confirm the price for the job before you book. This is what makes a difference:
- The shape of the roof and its details
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- How tall the building is and how easy the roof is to see
Flat roof survey starts from £150, including VAT. The final price depends on the size and height of the roof, how it can safely be seen and which survey you book.
Booking your survey
To price your survey accurately, we’ll ask about:
- Photos of the roof, taken safely from the ground or a window
- What kind of property and roof it is
- Where any leaks, stains or damp patches show inside
- The reason for the survey, such as buying, a leak or storm damage
To get a price for flat roof surveys in Letty Green, phone 07833 053749 or use the contact form. The address, the type of property and what you’d like to know help us give you an accurate price.

Useful tips for Letty Green property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Check from a window for ponding after heavy rain
- File the paperwork for the roof and any repairs
- Limit foot traffic on the covering
- Note any new marks on ceilings beneath the roof
If you are buying, the report gives you something specific to take back to the seller or agent. It can support a request for work before completion or a conversation about price, depending on what we found.
Have the roof surveyed every few years, and after any work that goes through it. You will spot changes early and have a record to look back on.
