Flat roof survey in Woolmer Green: what you get
Each flat roof is looked at from the safest viewpoints we have: from the roof itself where that is safe, from windows and nearby vantage points, and from inside where there is access. We don’t walk on fragile rooflights or fragile roof sheeting. If part of the roof cannot be seen or reached safely, the report says so, so the limits of the survey are clear. Typical surveys look at water getting in at rooflights and edge trims that have lifted or split, across EPDM rubber, felt flat roofs and mastic asphalt.
In a small place like Woolmer Green, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Different roofs, different checks
Single-ply membranes
Single-ply membranes can be damaged by foot traffic and equipment on the roof. Any tears, punctures or loose membrane are recorded with photos.
GRP fibreglass
A well-laid GRP roof frequently lasts up to about 30 years. Cracking where boards meet or where the deck moves is a common early sign of trouble.

Tips that help
From years of surveys, a few habits stand out:
- Note the date and type of any roof work
- Ask whoever fits equipment on the roof to make good the covering
- Note any new marks on ceilings beneath the roof
- Plan a survey before the covering reaches the end of its usual life
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.
What affects the price in Woolmer Green
We confirm the price for your survey before you book. This is what makes a difference:
- Chimneys, valleys, parapets and other details
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
- The package you choose: Basic, Standard or Premium
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.
Helping us price your survey
A little information up front helps. It helps to include:
- Pictures of the roof from a safe spot, if you have them
- The kind of building and roof involved
- Any marks or damp showing indoors
- Your postcode, so we can check access and travel
Booking is simple: just phone 07833 053749 or send us an email and give us some details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
What a flat roof survey looks like in Woolmer Green
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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Knebworth House, about 2 miles north-west, is one of the historic houses in the wider area around Woolmer Green. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you own a rental within reach of Knebworth station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you run a business near Howard Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Woolmer Green is about 4 miles north of Welwyn Garden City, in Hertfordshire. Roofs in Woolmer Green get the same thorough look as anywhere else in Hertfordshire. Woolmer Green is one of the places in Hertfordshire where we work. For surveys nearby, see our London page.

The survey, step by step
We check the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Older roofs in small places like Woolmer Green can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- 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 is access.
- The roof is inspected from every safe viewpoint, without walking 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.
Preparing for the visit
- Leave side gates unlocked
- Tell us about parking before the day
- Tell us about any leaks, stains or damp patches you know of
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or send us an email whenever suits you.

Woolmer Green: your questions answered
Do you cover smaller places like Woolmer Green?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Does a conservation area affect roof work in Woolmer Green?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
What will the report tell me?
A written report with photos, covering the condition of the flat roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Is a flat roof survey the same as a building survey?
No. It’s a survey of the flat roof. It’s not a RICS Level 2 or 3 home survey or a structural engineer’s report. It often sits alongside a buyer’s building survey.
Can you survey a flat roof on an office or unit?
Yes. Commercial and residential flat roofs are both covered. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
How do I book a survey in Woolmer Green?
Just ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day.
How soon will I get the report?

Common roof problems in Woolmer Green
Every flat roof covering has a working life. Felt roofs frequently last around 15 to 20 years, EPDM often 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
Problems we come across often include:
- Cracked or split membrane
- Dips that suggest the deck is deflecting
- Loose or cracked edge trims
- Failed seals around rooflight kerbs
Take a building like St Michael's Woolmer Green CofE VA Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
Before you book anyone
- Whether you get a written report with photos
- Will they check the loft as well as the outside?

Why get it checked now?
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. Surveying the roof in good time means work can be planned and budgeted around the people who use the building. Outbuildings and barns around Woolmer Green are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
Flat roof survey starts from £150, including VAT. The final price depends on how big and how high the roof is, how it can safely be seen and which survey you book.
