What we look for on each type of roof
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. The survey looks at welded seams, edges, fixings and signs of damage.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
Flat roof surveys for homes and businesses in Codicote
If the house you’re buying has a flat roof on an extension, dormer or garage, it’s worth knowing its condition before exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. That gives you facts to raise with the seller or agent. We survey felt flat roofs, mastic asphalt and EPDM rubber, and common reasons people get in touch are loose or cracked edge trims and blisters and bubbles in the covering.
Outbuildings, garden rooms and garages in places like Codicote frequently have flat roofs of their own. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what is not.

What else we do in Codicote
Flat roof surveys in Codicote: local notes
With Shaw's Corner about 1.7 miles south-west, Codicote sits in an area with a long building history. 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. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you live in an older home near Parish Church of St Giles, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For landlords with property near Knebworth station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building such as Codicote Church of England Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Codicote is about 4 miles north-west of Welwyn Garden City, in Hertfordshire.

What we do, step by step
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. It normally takes between one and two hours on an ordinary house, though large, tall or awkward roofs take more time. A visit to a smaller place like Codicote is no different on the day: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- 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 is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
Preparing for the visit
- Keep pets in another room
- Mention any parking restrictions on your street
- Make sure the loft hatch can be reached

What this survey cannot tell you
A survey is a close look at the flat roof, but it can’t do everything. The main limits are:
- Whether old sheeting or boards contain asbestos
- Fragile surfaces, which we don’t walk on
- The condition of the deck or insulation hidden under the covering
If you are not sure which survey you need, call 07833 053749 or drop us an email and we will give you a straight answer before booking. What our survey covers.
What we check
- Mastic asphalt
- Felt flat roofs
- EPDM rubber
- Upstands and outlets
- Single-ply membranes
- GRP fibreglass
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Look for standing water a day after rain
- Keep outlets clear of leaves and moss
- Note the date and type of any roof work
- Have the roof looked at again after a severe storm
After the visit, we write up the report with photographs of what we found. It explains the covering, its condition and every defect, and what we recommend. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Keep foot traffic on a flat roof to a minimum. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
Questions from Codicote
Do you carry out roof surveys in Codicote?
We do. Every survey there gets the same written report with photos.
Do you cover smaller places like Codicote?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Is it a structural engineer’s report?
No. We’re roof surveyors, not structural engineers, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
How many years has my flat roof got left?
We don’t put a figure on it. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but the report tells you how your roof is really doing.
How many surveys have you done?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
Will the survey show why my flat roof is leaking?
We check the covering and every detail where leaks commonly start, and photograph anything that could be letting water in. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
How quickly is the report sent?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What affects the cost of flat roof surveys
To price your survey, we check:
- Roof area
- Which survey package you book
- How many separate roofs there are, such as extensions, dormers and garages
- Height and safe access
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Getting in touch
Before you get in touch, it’s useful to have:
- The address and postcode of the property
- Any deadline, like an exchange date
- How the loft is reached, if there is one
- The type of building and roof, like pitched or flat
Once you know what you need, call 07833 053749 or drop us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.
Why get it checked now?
If you are buying, find out about the flat roof before you exchange. Once you’ve exchanged, any work on the roof is down to you. A report gives you facts to put to the seller or agent. On a bungalow or cottage around Codicote, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.
Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
