Flat Roof Survey in Coleman Green
Get a clear view of the flat roof at a property in Coleman Green. We visit on weekdays and at weekends.
- Ponding water that doesn’t drain away
- Blocked or damaged outlets
- Gaps at upstands and abutments
What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
Flat roof survey in Coleman Green
Our Basic Survey, from £150, gives you a visual inspection with photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. On a flat roof, moisture readings can help show whether water has got under the covering. Larger commercial roofs are quoted for their size. If you are worried about splits and cracks in the covering and dips that suggest the deck is deflecting, we can find out what’s behind it, on felt flat roofs, mastic asphalt and EPDM rubber alike.
Some older homes in villages like Coleman Green are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
We keep jargon out of it: if work is needed, the report says so clearly.

Roof by roof
Felt and built-up roofs
On felt, the upstands and edge details often fail before the main surface. Every upstand and edge is looked at, with photos of any that have lifted or cracked.
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. Our report notes cracks and any sign that the deck is flexing.
What we can’t see
It’s a careful look at the flat roof, not the whole story. Its limits include:
- The condition of the deck or insulation hidden under the covering
- Fragile surfaces, which we don’t walk on
- Whether old sheeting or boards contain asbestos

Flat roof surveys around Coleman Green
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 2.5 miles north lies Shaw's Corner, a reminder of how long the area around Coleman Green has been built on. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
For businesses in and around places such as Howard Centre, a flat roof over a business is out of sight and out of mind until it leaks. For site and facilities teams at buildings such as Beech Hyde Primary School and Nursery, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you let a flat or house near Welwyn Garden City station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Practical tips
There’s plenty you can do without going near the roof. What helps most:
- Clear roof outlets and gutters each autumn
- File the paperwork for the roof and any repairs
- Check ceilings under the roof for damp patches
- Check that new brackets or units haven’t damaged the covering
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.
Get splits, lifted seams and loose trims seen to while they’re small. A flat roof that’s looked after between surveys usually lasts longer.
Rented homes, blocks and businesses
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Landlords and agents in Coleman Green book surveys as well as householders. A photo-illustrated written report gives you a clear record of the flat roof.
FAQs for Coleman Green
Do you cover Coleman Green?
Yes. We survey roofs across London and South East England, and Coleman Green is part of that. Just call 07833 053749 or send us an email and let us know about the property.
Is Coleman Green within the area you cover?
We do. A small place gets exactly the same survey as a big one.
Will you check the loft?
Normally, if there is one and it can be reached safely. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
How much is a survey?
Flat roof survey starts from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we’ll explain what’s needed.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Do you check flat roofs for asbestos?
We do not test for asbestos. Where a roof has materials that might contain asbestos, like old cement sheeting, the report flags them and recommend a specialist asbestos surveyor.
How it works
The visit has one job: to look at the flat roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes about 1–2 hours on an ordinary house, or half a day or so for a commercial building. Somewhere like Coleman Green needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it is safe.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- 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.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- Tell us about any leaks, stains or damp patches you know of
- Move anything stored under the loft hatch
- Gather any invoices or paperwork from past roof work
Getting a price
