Prices for flat roof surveys in Tyttenhanger
What a survey costs depends on the time and equipment it needs. The main factors are:
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
- Height and safe access
- The roof’s overall size
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
What to tell us when you get in touch
When you call or email, these details help:
- Pictures of the roof from a safe spot, if you have them
- Any stains, drips or damp patches you’ve seen indoors
- Whether there’s a loft hatch, a shared roof or tricky access
- What kind of property and roof it is
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To send them or to book, phone 07833 053749 or send us an email.
Flat roof survey in Tyttenhanger
Ponding is frequently the first sign that something on a flat roof is not right. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey felt flat roofs, single-ply membranes and GRP fibreglass, and the problems we are asked to look at most are dips that suggest the deck is deflecting and outlets choked with leaves and silt.
In a small place like Tyttenhanger, a flat roof can stand in the open, 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. Exposed edges are typically the first part of a flat roof to go.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof, the defects we found and what we recommend.

Roof by roof
GRP fibreglass
GRP roofs can last up to about 30 years when they’re laid well. Cracking where boards meet or where the deck moves is a common early sign of trouble.
Felt and built-up roofs
On felt, the upstands and edge details often fail before the main surface. We check each one and photograph any that have split or pulled away.

Flat and commercial roofs around Tyttenhanger
With Batchwood Hall about 3.3 miles north-west, Tyttenhanger sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you run a business near The Maltings, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For landlords with property near St Albans station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If your house is among the older ones in the streets near Church of St Mark, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.

FAQs for Tyttenhanger
Is Tyttenhanger in the area you cover?
Yes, Tyttenhanger is one of the places we work. Every survey there gets the same written report with photos.
How do I find out if my home in Tyttenhanger is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Does a flat roof survey replace a RICS survey?
No. Our survey covers the flat roof only. It is not a RICS Level 2 or 3 home survey or a structural engineer’s report. Many buyers use it alongside a building survey.
What does ponding on a flat roof mean?
Standing water on a flat roof deserves a closer look. It can point to blocked outlets, poor falls or a deck that is sagging, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Will the survey show why my flat roof is leaking?
We check the covering and every detail where leaks commonly start, recording anything that could let water through. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
Do you give a life expectancy for the roof?
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.
For landlords and managing agents
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
An agent can book and manage the survey for a landlord. We agree a time with the tenant beforehand.
Tips from our surveys
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Clear roof outlets and gutters each autumn
- Note where water lies after a downpour
- Watch the ceilings below the flat roof for stains
- Ask contractors to protect the roof if they work on it
For landlords and building managers, the report is a dated record of the roof’s condition. It is useful when planning upkeep and setting budgets, and it makes changes easy to spot at the next survey.
Have the roof surveyed every few years, and after any work that goes through it. You’ll spot changes early and have a record to look back on.
The survey, step by step
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take an hour or two for most houses, with bigger or more complicated roofs taking longer. In a hamlet or village like Tyttenhanger, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start with the address and, on larger roofs, the roof area and access.
- 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.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Make sure pets are kept safely away
- Note where any stains or damp appear
Booking a survey

Related advice
Leave it or get it looked at?
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, so you can plan the work rather than react to it. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
